    Hello everybody,
    on my PC I have already many partitions and it is very bad that VeraCrypt mounts the encrypted partitions on additional letters. It doubles the busy letters. Though I don't need to have all the partition encrypted on my HDDs, when I connect my backup hard disks, almost all the available drive letters are already busy. I have several backups HDDs with 4-5 partitions each one. Change the letter assignment in the disk manager of Windows on each PCs and not only one time is very annoying.
    This doesn't happen with DiskCryptor, which looks to be very similar to VeraCrypt. The encrypted partitions keep the same letter.
    DiskCryptor has some other disadvantage with its driver for me, then I would prefer to use VeraCrypt, but this behavior with the drive letters makes it not a practicable solution. I can use VeraCrypt only for small USB drives with only 1 partition inside.
    Would it be possible to change the letters' behavior?

    Based on your title, it seems you did not remove the Windows drive letter assignment after you encrypted a partition.

    For example, if the partition you encrypted was already assigned the drive letter H by Windows, when the VeraCrypt encryption completed, you need to go into Windows Disk Manager and remove H from the now RAW partition (RAW is how Windows OS will see the VeraCrypt partition) so you can mount in VeraCrypt that partition again as drive letter H.

    Hello. Thank you for your reply. Reassign manually each drive letter is what I would avoid to do, since I have to mount the external backup HDDs with encrypted partitions on several PCs. DiskCryptor looks to be very similar to VeraCrypt and it keeps the same letter, independently by if the partition is encrypted or not. Couldn't VeraCrypt work in the same way? I don't know the technical differences, but at least as user interface, they looks to be very similar.
    Or could VeraCrypt do this letter reassignment automatically in the background? (I don't know in which way it works on DiskCryptor, but as told, its issue for me is that DiskCryptor doesn't work in portable mode)

    Perhaps the developer of DiskCryptor @davidxanatos could help the VeraCrypt developer @idrassi by submitting the code that performs the driver letter reassignments.

    Hi, it would be very good. I got the information that DiskCryptor doesn't need additional drive letters, because it installs a filter driver. I don't know whether it is es easy to implement, but you could implement the same driver, when VeraCrypt is not used in portable mode. So, people which have many encrypted partitions and backup HDDs have no troubles with drive letters.
    Would it be possible?

    Additional info: DiscCryptor uses a driver that works differently than the driver of VeraCrypt and it requires a reboot to get installed. It can't work directly on the fly in portable mode, but it doesn't require to use additional drive letters. I don't know whether VeraCrypt could integrate also this driver and use it when VeraCrypt is installed in the system, not used in portable mode.
