    Hello,
    My Truecrypt volume has suddenly started giving me this error.

    I tried to do a chkdsk and I got this
    "C:\Users\Tarek>chkdsk u:
    The type of the file system is NTFS.

    WARNING! F parameter not specified.
    Running CHKDSK in read-only mode.

    CHKDSK is verifying files (stage 1 of 3)...

    0 large file records processed.

    Errors found. CHKDSK cannot continue in read-only mode.
    "

    I tried to restore the Volume Header, didn't help.
    I tried to reboot and change the drive letter, didn't work either.
    I tried GetDataBack for NTFS, it recovered like 5 files out of hundreds of files.

    My data is pretty important and as far as I can remember, last time I did dismount and everything was fine. No power outages, no sudden reboots, nothing.

    What should I do?

    Because you were able to recover a few files, it looks like TC is decrypting the volume but there are errors on the disk.
    Your disk is failing or has become corrupted.

    You didn't specify what type of TC volume. Is this File, Partition, or Disk hosted partition?

    What you need to do is make a copy of the volume before doing anything else. Mount the copy and allow CHKDSK to do its thing on this copy.
    Depending on the volume host type, and OS, you could let TC decrypt it and then try to use recovery software.

    I mounted it, and used a recovery software. Pretty much everything was intact except for some files that got copied into the wrong folders, but yea it was manageable. I used CrystalDisk later and it said that I have 26 (Decimal, not Hexa) bad sectors. So yea, it seems I got those because we get a power outage every day or two days :(

    Either get a UPS or make a copy of the data on flash, DVD, SSD whatever.
    Actually, make a backup whether you use a UPS or not. Encrypting your data just makes it that much harder to recover when things go wrong.
