Peer-to-peer networks significantly speed up data transfer, so torrents are used by millions of users around the world to download movies, music, programs and much more. What a disappointment befalls an ordinary person who wants to download a movie: he spent time finding it on the Internet, opened a torrent client, and when downloading, the error “Access denied (Write to disk)” pops up. And everything would be fine, but the malicious error does not disappear either when deleting and assigning a new download, or when restarting the program.
What kind of error is this and will we now have to download the movie directly from the browser at a snail’s pace? Let's try to figure it out together.
Rehashing a torrent in BitTorrent
Sometimes, if you interrupted downloading via torrent for a long time, part of the downloaded content could for some reason be deleted from the computer’s hard drive, or the seed added new files to the distribution. In this case, when you restart the content download, the torrent client will display an error. What to do? You need to check the torrent file located on your computer and the one posted on the tracker for identity, and in case of discrepancies, bring them to a common denominator. This procedure is called rehashing. Let's describe this process step by step using the example of working with the popular program for downloading torrents BitTorrent.
Reason 2: Lack of peers
The quality of downloading depends on the number and availability of peers. After all, peers are the total number of all users performing any manipulations on a torrent file. If the client does not connect to peers, it is possible that the distribution to the uploaded file is very old or that seeders come in very rarely. In this case, you have two options:
- Look for a more recent distribution, with more users.
- Wait until at least someone appears who is able to distribute fragments of the object.
Rehashing torrents
In the BitTorrent program, we are seeing a problematic download that cannot complete correctly. To solve this problem, let's rehash the file.
By left-clicking on the download name, call up the context menu and select the “Recalculate hash” item.
The hash recalculation procedure starts.
After it ends, we re-launch the torrent.
As you can see, the download has now continued as normal.
By the way, you can also rehash a normally downloading torrent, but to do this you first need to stop its downloading.
As you can see, the procedure for rehashing a torrent is quite simple, but many users, not knowing its algorithm, panic when they see a request from the program to rehash the file.

I set it to download GTA5. But at 80% the torrent froze and gave the following error. I thought I would have to download the game again. But I decided to google the error and found a solution. The method really works. Previously, I did not know that it was possible to bypass this error and downloaded it again. Thank you. They helped.
Please! Always happy to help!
Can you use this to correct hash errors and recover lost meters?
When checking the video season hash, BitTorrent freezes and does not reset even in the task manager, and a reboot does not occur, only a forced one helps.
It seems. The problem was in the HDD.
Thanks a lot! I had a similar situation with Media Jet. I didn't know what to do next. Setup.exe and Autorun were missing. Before downloading, use the “Check data integrity” menu.
re-ashed the hash, but there are 2 hash modifications
I always have a problem with the Torent client (it doesn’t matter whether it’s qBittorrent or uTorrent) when I reinstall it to a new version or when I reinstall Windows OS. the problem is this: I distribute several dozen releases (music/albums) on rutracker_org and when I delete the old client, for the new one I will have to download the torrent files of my releases again (hoping that besides me there is also someone seeding my distribution) in order to stand at the distribution, that is, as if at one’s own place. but the whole point is that I don’t want to update releases by creating new torrent files and uploading them to the tracker, because it resets the number of downloads and the date of the posted release, and there are no identical published releases that are on the tracker on my PC (I have my own sorting albums, deleting some songs, etc.). in the end, I downloaded half because they were seeded, and half not, because I was the only one seeding. Now I have an old version of qBittorrent, I want to remove it and install a new one (or even reinstall the OS), how can I somehow put the torrent files of my distributions that are currently active on the PC into the newly installed client?? is it even possible?
When right-clicking on a file, the “recalculate hash” button does not work. The article does not say what to do in this case.
none of the above helps, but I want to download it
Good afternoon. What's your problem? It's not clear from the screenshot. Slow loading aphids in something else? If the situation is slow loading, then there may be situations that you cannot influence. For example, the line capacity or the absence of seeds on the distribution. Well, you can still try to solve the first question by contacting your provider. And the second one can’t be solved. Unless you find an alternative distribution.

Third party software
There is a huge amount of software for editing Windows startup. We will look at one of the best utilities, which is called CCleaner. And you need to work with it as follows:
- First, of course, we download the latest Russian version of the program. Next, run the resulting file and perform the installation.
- When the program starts, go to the “Tools” tab. It's in the left side menu. When this is done, in another side menu, select the “Launch” section (o). Next, when a list of all programs launched along with the operating system appears, select ours with the left mouse button.
- As a result, two options will become available on the right side of the window: disable and delete. This and other buttons remove the selected program from autorun.
Now the torrent should definitely not start along with the computer.
Expert opinion Vasily Project manager, comment moderation expert. But if this software independently adds itself to autorun, then we can regard it as malicious and use the option given below.
How to rehash a torrent, fix errors and download files
A very large number of people take advantage of the BitTorrent Internet protocol. This wonderful technology allows you to very quickly receive or transfer any large files. Modern torrent clients are extremely easy to use and learn.
However, just as there is nothing ideal in the world, BitTorrent technology is not thorough and trouble-free. Whatever client program is used to download torrents, sometimes errors and crashes occur. In most cases, these problems can be easily fixed - you just need to know how to rehash a torrent. Let's take a closer look at this and figure out what a hash sum is and why problems may arise.
Why do files continue to be downloaded or distributed during pause mode?
Because the utorrent torrent system, which works using the BitTorrent protocol, does not complete the downloading/distributing process immediately. uTorrent must first receive or send all file sharing items from the queue. Therefore, the connection does not break after it is turned off and some reception and transmission activity is possible for several minutes (usually 1 - 3 minutes allows you to download or distribute files). This is the feature of the BitTorrent protocol that makes it very effective and so popular.
Hash errors
In P2P networks, the hash is used to verify the integrity of the downloaded or distributed file. For example, a hash error will definitely occur if the seeder has made changes to the seeded file or damaged it. Very often, similar situations occur when downloading music audio files.
This can happen when the seeder, after some time has passed since the creation of the distribution, changes the tags in the distributed audio compositions. Or, for example, a video file is distributed, and then subtitles are added to it. In both situations, there will be a hash mismatch and errors will occur. In the case when such an error occurs when downloading very important content, moreover, with a single seeder, a user who does not have information about how to rehash a torrent will have to spend a lot of effort and time solving the problem.
The second way to solve the problem when uTorrent loads your hard drive.
The essence of this method of solving the problem of loading a uTorrent hard drive is to artificially limit the speed of downloading and uploading files. To do this, you need to artificially limit the speed of downloading and uploading files in each active torrent. As a result of this, the load on the hard drive will significantly decrease and most likely the message that uTorrent is loading the hard drive will disappear.
It is up to you to decide which download and upload speed to choose specifically on your PC. Because The performance of different hard drives is different, and the speed of their operation is correspondingly different, hence the conclusion that the speed must be selected experimentally. Gradually, in small steps, reduce the download and upload speed until uTorrent stops loading the disk 100%. If this method also did not help you, then read the next, most radical method of solving the problem.
There are a fairly large number of ways to solve the problem of loading uTorrent hard drive 100%. In the first two ways to solve the problem, the most common methods were considered, but they are not alone, there are many other options for solving the problem, individually for each PC (personal computer).
Types of hash problems
In most cases, problems when downloading torrents arise due to “excess” and hash sum errors. “Redundant” data is data that was rejected by the client or simply corrupted during transmission. Data sent by the peer is rejected by the client program if the algorithm embedded in it considers that this data is not needed.
A “hash sum error” occurs when the data does not pass the integrity check, that is, it is simply corrupted. By the way, if the amount of corrupted data is small, you should not worry - the torrent client discards this data, but then downloads it again.
How to identify errors?
Before we figure out how to rehash a torrent, let's look at the signs of the problem:
- During the download of a distribution characterized by a sufficient number of distributors, constant download interruptions occur.
- After all the files from the distribution have been downloaded, it is discovered that the volume of data received greatly exceeds what is stated in the description.
- Acting as a seeder, the user discovers that the distributed file has several leechers, but they, even after a long period of time, do not join the seeders. At the same time, the load rate of peers freezes at the level of 98-99%.
- Among the downloaded distributions there are those whose downloading has stopped at 98-99%.
How to rehash a torrent?
There is a simple method that almost always works to defeat hash errors.
You can solve the problem yourself with just a couple of mouse clicks. In all known torrent clients, just stop the distribution, right-click on its name and click on the “Recalculate hash” item in the context menu. The scan will begin at that very second, and after it is completed, the torrent file will no longer deliver problems.
Please note that the hash recalculation item in the distribution menu may have different names. In popular client programs there are names “Force recheck”, “Force Re-check”, “Force check” and the like. The user can safely select these items, and questions about how to rehash a torrent and download files should no longer arise - this simplest method helps in most cases.
OS startup management
Any operating system, including Windows, has its own tools for working with startup. Let's look at how this is implemented, for example, in Windows 10:
- Initially, launch the task manager. To do this, right-click on an empty space on the taskbar and select the item indicated in the screenshot from the context menu.
- If you launched this system utility for the first time, in its lower left part we will see the “More details” link. Next, switch to the “Startup” tab, find the application that we want to remove from startup, and by right-clicking on its name, select the disable option.
As in the previous case, after restarting the computer, the program should not automatically start. If this method does not work, and the torrent continues to start automatically, we can resort to the so-called heavy artillery.
Common torrent client errors, how to fix them
torrent error If you find yourself on this page, it means you are out of luck, and a torrent error is preventing you from downloading the distribution that you so badly want. Perhaps you have prepared yourself a delicious dinner that you want to eat while watching some movie or TV series, but, as luck would have it, it does not want to load due to a damned error in the torrent client. Then I don’t envy you - the situation is unpleasant, and it needs to be corrected, otherwise dinner will get cold and the evening will be ruined. I just really hope that your torrent client is throwing one of the common errors, and my recommendations can help you.
Setting up uTorrent using the BEncode Editor utility
These were the standard parameters. If uTorrent still says that the disk is 100% overloaded, then you can try an advanced setting. In this case, you will need the BEncode Editor utility.
With its help, you can configure uTorrent so that it downloads files of one torrent one by one, and not all at once (for example, episodes in TV series). This will help reduce the load on the hard drive and remove the message HDD is 100% overloaded.
To do this:
- Quit uTorrent.
- Launch BEncode Editor.
- Go to: C:UsersUsernameAppDataRoaminguTorrent (AppData folder is hidden, so make it visible).
- Find the settings.dat file and drag it into the BEncode Editor program window.
- Select the first line (ROOT), click on the green plus sign and in the window that appears, enter the following settings: Name - bt.sequential_download, Type - Integral, Value = 1. Click "OK".
- Select the second line (fileguard) and delete it. This is to prevent uTorrent from creating a new file with the same settings when you restart it.
After that, you can launch Torrent and download any movies, games, music. The error disk is 100% overloaded should no longer occur.
The most common torrent client errors and methods for fixing them:
Error: write to disk access denied
Cause: The torrent client does not have sufficient rights to write to the disk. How to fix: - Go to the properties of the folder into which you are downloading the “problem” file(s), and uncheck the “Read-only” option. Restart your torrent client. — Close the torrent client and open the properties of its shortcut. On the “Compatibility” tab, check the “Run this program as an administrator” checkbox.
Error: The system cannot find the specified path
Reason: 1. The folder into which you are trying to download something does not exist, and the torrent client cannot create it; 2. The path to the folder is too long and the torrent client cannot read it (the system limit is 255 characters); 3. Uploaded files have been moved or deleted. How to fix: - Check the presence of the folder into which the distribution is downloaded. Create it if necessary. — Make sure that the folder is located closer to the root directory (C:Downloads, for example). — If you receive the error “The system cannot find the specified path” when trying to resume downloading a distribution that has already been partially downloaded, check whether parts of the files are still there and rehash the distribution. To do this, in the torrent client, right-click on the desired distribution and select “Update hash”. If the error persists, delete the torrent and add it again. It is advisable to upload to a different location from the previous one.
Error: The process cannot access the file because the file is occupied by another process
Cause: Some other application is interfering with the torrent download. This error, when a torrent client cannot access the downloaded file, most often occurs due to processes occurring in the Windows system itself. This is usually associated with multimedia files (pictures, video files, etc.). When the system finds similar files, it adds them to its index. Those. accesses the file, and since the system has a higher priority, uTorrent has no choice but to “complain.” How to fix: - Disable thumbnails for files and folders. To do this, select “Run” from the Start menu or simply press Win + R on the keyboard. Enter the control folders command in the field and click Ok. Folder Options will open. On the "View" tab, find "Always display icons, not thumbnails", check the box and confirm with the Ok button. — If the error still occurs, try adding the torrent client to your antivirus exceptions. — Do not open files/folders until the download is complete.
These were the 3 most common errors that bother users of bittorrent networks year after year. Unfortunately, these errors are not caused by the torrent client as such, otherwise they would have been fixed long ago. Therefore, even the correct setting will not save you. In fact, there are much more errors, but there is little point in describing them, because they appear extremely rarely. However, if you have any problem and you cannot download the torrent without errors, write about it in the comments, I will definitely help. That's all!
Set up caching
Let's manually tell the program how much RAM space can be used for the cache. This will not greatly reduce the amount of information written to the disk per unit of time, but it will significantly reduce the number of accesses to it. Open uTorrent settings and in the left panel, click on the plus sign next to “Advanced”.
From the submenu that opens, go to “Caching”.
Check the “Use the specified size instead of auto-select” checkbox. Then write the number 128 in the box on the right (this is the number written there by default) and click OK.
Did it help? If not, open the caching settings again, and now set the number to 256. Each time, increase the number of megabytes by 128 until you reach 512. Save the settings and check if the error disappears. To be on the safe side, you can restart uTorrent each time.
What is a hash error in uTorrent
Hash errors in torrents don't happen often, but everyone faces a similar problem from time to time. If such an error occurs when downloading the necessary content with a single seeder, a user who is not familiar with this problem will spend a lot of time and effort solving it.
P2P networks use a hash to verify the integrity of the file. If the seeder has changed or damaged the distributed file, an error will inevitably occur. Most often, this situation occurs with music audio files, when a participant first creates a distribution, and after a while decides to change the tags in the audio compositions. The hash sum does not match and errors occur.
Lack of free disk space
Quite rarely, but it still happens that a torrent access error appears when there is not enough free disk space.
The solution suggests itself: you need to clear the disk of everything unnecessary or (if there are several logical partitions) change the purpose of not only the download folder, but also the disk. How this is done has been stated above.
How to identify and fix hash errors in a torrent
First, let's look at the signs:
- When downloading a torrent with a sufficient number of seeders, the download is constantly interrupted, although the file has been downloaded completely.
- After downloading the torrent, you discovered that you downloaded more than the volume stated in the description (the weight is 400 MB, but you downloaded 600 MB). This is surplus.
- You are seeding a file to which several leechers have joined, but even after a long time, these users do not join the seeders, and the peers show that their downloading has stopped at 98-99%.
- Among the torrents you download, there is one whose downloading stops at 98-99%.
Let's look at several ways to help fix hash errors:
- While receiving data, uTorrent compares the hash amount, and if it doesn't match, it downloads that part again. It is because of this that surpluses appear. Some torrent clients may block a user who submits such incorrect data. Using personal messages, you can contact a person on the tracker and ask them to re-upload the distribution.
- You can solve the issue yourself by trying to rehash the torrent. Select the required task and right-click on it. Find the "Update hash" option.
To prevent such troubles, use trusted clients, for example, uTorrent. Do not edit file tags yourself and make sure that your player does not change them automatically.
Check HDD
First, never download torrents to an external hard drive connected via USB. This is not the most reliable connection method, nor the fastest. From time to time, due to the low bandwidth of the uTorrent interface, it will show the error “disk is 100% overloaded” and reset the download speed to 0. Until the pieces of files in RAM are written to the HDD.
Next, make sure that the hard drive on which downloaded torrents are saved is in good condition. Check the drive status information in SMART Install the CrystalDiskInfo program and see if all attribute values are within tolerances (all circles on the left should be blue). If SMART shows errors, this is very bad. Such disks first only slow down, and then suddenly die, taking with them to the grave all the information stored on them. We recommend that you save all files to another drive as soon as possible and stop using that HDD.
