Freezing and data loss on Windows 8


I have a number of mounted volumes on Windows 8. Previously they were TrueCrypt volumes and all was well. I removed TrueCrypt and installed VeraCrypt instead, and writes to those volumes started to randomly fail.

The symptoms are that I become unable to access files on those volumes, getting "file not found" messages while other apps are apparently still writing data without issue. Eventually I am unable to list drives on the computer, via command prompt, disk manager or Explorer. As more processes hang due to pending I/O the system becomes unusable and is unable to shut down or restart.

I tried upgrading the volumes to VeraCrypt volumes, but this did not improve things. Rolling back to TrueCrypt seems to have fixed the issue.

I did some further investigation and it's definitely Veracrypt. The machine is stable with Prime95 for a few days, after removing Veracrypt. I re-installed TrueCrypt and it's still fine.

There is something about the VeraCrypt driver that causes these severe issues. Is there some way I can debug it?

Decrypt them(with the last app that worked), uninstall veracrypt, reinstall veracrypt(beta 1.18) and encrypt them again.
