About uTorrent Error Former Volume Not Mounted

The former volume not mounted is an error that may occur in uTorrent. The volume refers to a storage device like a disk drive or USB flash drive. A volume is mounted when it is assigned a place in the file system of the computer so that it can be referred to at that path.

The problem has been reported by a number of users, and it might also occur on other popular torrent clients like BitTorrent and Vuze. You may learn about the details of the uTorrent error former volume not mounted from the following post:

Normally I keep all my uTorrent downloads stored in an external hard drive. I plug the drive into my PC after my PC has booted up. Today I went through the usual procedure but also added a USB stick with a view to copying some files from the external disk to the stick. Before doing this, I opened uTorrent with a view to rename one or two files, but every file had turned from green to brown with the message “Error former volume not mounted”.
I’m convinced that the introduction of the USB stick had something to do with this, but the question is, is there a way to get the files seeding and downloading again?  — From uTorrent forum

Commonly, the frustrating problem occurs when users are using an external storage device and it prevents them from reading or downloading torrents normally. There are several potential factors that may lead to the former volume not mounted error in your torrent client. Some of them are listed below:

  • There are some issues with the drive letter. One of your torrents or download paths probably uses a drive letter that no longer exists, or the external drive is assigned with another drive letter different from that your torrent client expects.
  • The torrent is partially corrupted. If the downloading process of the torrent is interrupted unexpectedly, the data might be corrupted and your torrent client may refuse to resume download, giving the former volume not mounted error message.
  • The resume.dat file contains certain conflicting data. It is possible that the resume.dat file of uTorrent contains certain incorrect instance, and this may also trigger the problem under our discussion.

After learning about the error in detail, it’s time to fix it. In the following contents, you will learn about 6 possible methods to fix uTorrent former volume not mounted error. Let’s check them out one by one.

Fix 1: Reconnect the Problematic Drive

As mentioned before, the problem is typically caused by the external drive like a USB drive being used as the storage directory of your downloaded torrents.

If you are using such a drive and frequently disconnect it from your computer, it is possible that its drive letter allocated by the computer changes and thus your uTorrent cannot recognize the drive. Besides, if the drive is not properly connected, you could also encounter the former volume not mounted error.

Therefore, you had better disconnect the problematic drive and then properly reconnect it to your computer. This will force your operating system to reassign a drive letter to the external drive and may fix the problem automatically.

Fix 2: Set Another Download Location for the Problematic Torrent

In some cases, this problem just happens to one specific torrent which is referencing a download path that no longer exists. According to the reports, this commonly occurs when you perform downloads on a removable drive but then decide to remove it while the file is downloading or seeding.

If you are in the same situation, perhaps you can try setting another download location for the problematic torrent to fix the issue. Here’s a simple guide for you.

Step 1: If the torrent is still under download, the first thing you need to do is stopping the current download to prevent your uTorrent from accessing or updating the file. Just right-click the torrent and choose Stop.

Step 2: Right-click the problematic torrent again and choose Advanced > Set Download Location.

choose Set Download Location

Step 3: In the pop-up dialog, choose a new valid location you want to store the torrent file and click the Select Folder button.

After that, restart your torrent client and check if you can download the torrent without the former volume not mounted error.

Fix 3: Match the Drive Letter to the One Allocated by the Computer

When you reconnect the external hard drive to your computer, the operating system can still recognize it by allotting a drive letter which might be different from the one previously allotted. However, the uTorrent might remember the previous drive letter (or the path) and it gets confused once the drive letter or mount point alters, which might lead to former volume not mounted error message.

In this case, you can change the directories for your torrents to match the drive letter to the one allocated by your computer. To do that, you should:

Step 1: Keep your uTorrent open and click Options from the upper ribbon bar.

Step 2: Click Preferences from the drop-down menu. You can also press Ctrl + P keys in the main interface to directly open the desired window.

choose Preferences

Step 3: In the left side of the Preferences window, click Directories, and then check Put new downloads in from the right pane. Here, check if the drive letter matches the current configuration. You should also make sure the drive letters of other involved locations are matched correctly.

Step 4: Click Apply and OK to save the changes you have made.

Now, you can restart your uTorrent and check if the problem is resolved. If you are still stuck with the former volume not mounted error, just move on to the next solution.
