How to Resolve the uTorrent Disk Overloaded Error in Windows?

The Disk Overload Error in uTorrent  occurs after the download speed reaches a certain threshold. In most cases, the error lats for about one minute (during which the download drops) before returning to normal. However, in most cases, the error is recurring and returns after just a couple of minutes.

uTorrent Disk Overload error

The most common reason that will cause this problem is the way uTorrent downloads data in a non-sequential way. This approach puts a lot of stress on your HDD due to the fact that it’s forced to write hundreds of parts at the same time in a random error. In this case, one way to ensure that the problem is not occurring is to enable file pre-allocation form the Advanced settings menu.

Keep in mind that newer uTorrent version is much more efficient with Disk Usage due to the fact that they are no longer using single-thread I/O. If this scenario is applicable and you’re indeed using an older uTorrent build, uninstall the current installation and install the latest stable build available.

Another popular scenario in which this issue will occur is a situation in which partfile is turned on so the drive is forced into a lot of file skipping. This problem was resolved with newer versions, but in case you don’t want to upgrade, you can circumvent the problem by accessing the Advanced options and setting the value of diskio.use_partfile to false.

If the issue only happens when you attempt to download large files or you attempt to download multiple files at once, the problem most likely occurs due to the fact that the base Cache is insufficient. To fix this, you’ll need to access the Preferences menu and enlarge the Disk Cache to superior value in order to prevent this problem from occurring.

1. Enable File Pre-Allocation

The main reason why uTorrent users are encountering the Disk Overload Error in uTorrent is due to the fact that the client downloads and uploads pieces in a non-sequential way. This is very different from a local transfer and puts much more stress on your drive – your HDD needs to read and write hundreds of random parts of the file at the same time.

This can become a problem with slow traditional HDDs. One way to ensure that the problem no longer occurs is to enable file pre-allocation from the Preferences menu. Several affected users have confirmed that the issue was completely resolved as soon as they did this modification.

Here’s a quick guide on resolving the Disk Overload Error in uTorrent issue by enabling file pre-allocation:

  1. Open your Utorrent client and go to the ribbon bar at the top.
  2. Click on Options and then select Preferences from the drop-down menu.
  3. Once you’re inside the Preference menu, select General from the left-hand section.
  4. Next, move over to the right-hand section and check the box associated with Pre-allocate all files under When Downloading.
  5. Once the modifications have been made, click on Apply to save the changes.
  6. Restart the uTorrent client and see if the issue is resolved at the next system startup.

2. Update to the latest uTorrent client

As it turns out, newer versions of uTorrent have become a lot more efficient with Disk usage. A simple explanation is that versions 3.1.3 and older previously used a complete single-threaded I/O.

Fortunately, the newer versions are multi-threaded and facilitate a much higher performance. With multi-threading, you no longer run the risk of seeing that a single disk job ends up blocking everything.

If you’re using uTorrent 3.1.3 or older, you should be able to fix the issue swiftly by uninstalling the current version and then downloading and installing the latest available stable build.

Here’s a quick guide on updating to the latest uTorrent client:

  1. Press Windows key + R to open up a Run dialog box. Next, type ‘appwiz.cpl’ inside the text box and press Enter to open up the Programs and Features menu.
    Type appwiz.cpl and Press Enter to Open Installed Programs List
  2. Once you’re inside the Programs and Files window, scroll through the list of installed applications and locate your uTorrent installation.
  3. Once you see it, right-click on it and choose Uninstall from the newly appeared context menu.
    Uninstalling uTorrent
  4. Inside the uninstallation screen, check the box associated with Remove my settings, then click on Uninstall and confirm to start the process.

  5. Once the process is complete, restart your computer and wait for the next startup to complete.
  6. After the next startup sequence is complete, access this link (here) scroll down and click on Download uTorrent Classic to get the latest version available.

  7. As soon as the installation executable is downloaded, open it and follow the on-screen instructions to complete the installation of the new uTorrent version.
  8. Once the newer version is installed, repeat the action that was previously causing the Disk Overloaded error and see if the problem is now resolved.

In case the same problem is persisting, move down to the next potential fix below.

3. Setting diskio.use_partfile to False

As it turns out, this is a known issue triggered due to file skipping when the partfile is turned on (it’s turned on by default). The majority of users have confirmed that the issue was resolved with version 3.3, but in case you don’t want to upgrade to a newer uTorrent version, there’s also an alternative.

To circumvent the Disk Overloaded error, you can open the advanced Preferences menu and set the value of diskio.use_partfile to false.

This operation will ensure that there is no more file skipping caused by the partfile. Here’s a quick guide on how to do this:

  1. Open up your uTorrent client and use the ribbon menu at the top to access the Options drop-down menu.
  2. Inside the drop-down Options menu, click on Preferences.
  3. Once you’re inside the Preferences menu, select the Advanced tab from the left-hand section.
  4. Move over to the right-hand section, paste ‘diskio.use_partfile’ in the Filter section and press Enter to locate the value.
  5. After you manage to find the correct name, select it by clicking on it once, then set the value from True to False and click on Apply to save the changes.
DIsabling diskio.use

In case you already enforced this modification and you’re still encountering the same Disk Overloaded error, move down to the next method below.

4. Enlarge the Base Cache

If you’re mainly encountering the issue when you attempt to download large files (10+ GB) or you attempt to download multiple files at once, it’s very likely that the issue occurs because the base Cache is insufficient.

In most cases, the issue will occur because the your disk is forced to write blocks to many different locations at the same time and it gets busy. One way to fix this issue is to enlarge the cache enough so that the writing takes place in a sequential way.

Here’s a quick guide on enforcing this change on every version of uTorrent:

  1. Open your default uTorrent applications and access the Options tab from the ribbon bar at the top.
  2. From the Options drop-down menu, click on Preferences.
  3. Inside the Preferences menu, click on the Advanced menu, then click on Disk Cache.
  4. With the Disk Cache tab selected, move over to the right section and start by checking the box associated with Override automatic cache size and specify the size manually.
  5. After you do this modification, change the value of the Disk Cache to 1024 Mb and click Apply to save the modifications.
  6. Restart uTorrent and see if the issue is resolved.
