![]() We will have to try them both (boot to each one and use it to restore the key data, then attempt to mount the volume from another OS). However, since you aren't sure which rescue disk is correct, it gets a little trickier. At this point the safest approach is to attempt to mount the volume from another OS, either by slaving the hard disk to another PC or by booting to a live CD, then running TrueCrypt and using the "mount without preboot authentication" command. So, in your case, once you confirm the password, the next step will be to use the correct rescue disk to restore the key data. However, this will probably not be a complete solution to the problem, as whatever damaged the TC header most likely affected other areas of the drive as well, particularly the TrueCrypt bootloader (which can also be restored from the rescue CD if needed). If your password works fine when you perform the above-mentioned test but it's not being accepted when you boot to the hard drive then the TC header (key data) on the hard drive most likely needs to be restored from the rescue CD. If you do, be very careful not to modify the drive. In this case you might want to re-try the test using a different computer. If you can't get past the "Incorrect password" message then you can assume that you are either typing the incorrect password for that particular rescue cd, or for some reason your correctly-typed password is not being passed on to TrueCrypt, possibly due to a keyboard issue or some other miscellaneous cause. (You might also get a warning that the hard drive already appears to contain a valid TC header).ħ) At this point (if you get this far) you should carefully press "n" so you don't end up modifying the drive, as this was just a password test and we weren't actually intending to restore the Key Data. If the password that you entered is validated by the header on the rescue CD then you will advanced to the next prompt: "Modify Drive 0? (y/n)". This procedure doesn't read the header (the "key data") from your hard drive at all, it uses the header data that's stored on the CD, so it's a good way to confirm that you are entering the correct password, even if the header on your hard drive was overwritten or damaged such that it can no longer validate your password:ģ) Choose Restore Key Data (volume header)Ĥ) At the password prompt, deliberately enter an incorrect password (such as "xxx") and notice that you receive the "Incorrect password" message.ĥ) Press escape once in order to get back to the Repair Options menuĦ) Select option again, this time entering the correct password at the prompt. Here's a way to use the TC rescue CD to confirm that your password is correct. I copied and pasted some of the following from one of my posts on a different forum (and I also edited it a bit): I need help, my whole life is on this drive I also tried restoring the volume header from the embedded backup, but that did not work either. I tried mounting the drive from within Ubuntu Live CD after installing TrueCrypt on the Live CD. Or is there any alternative method I could use to recover the files on this drive? ![]() ![]() The problem is, neither of the two discs are responding to the computers password (responding with Invalid Password), even though I'm 100% certain the password is correct.ĭo the recovery discs have different passwords? Is there any way I can determine which of these recovery discs is the correct disc to recover my partition with? but I've found two of them (I think for two different computers that I encrypted). Shortly after I remembered that this was a TrueCrypt partition and I located my TrueCrypt recovery disc. I asked the Ubuntu team for support, and the advised me to try to create a new Intel partition using TestDisk. I had some sort of awful lapse of judgement, and forgot that this was a TrueCrypt partition. When I tried to boot back into Windows, I received errors from GRUB complaining of partition not being found. I installed Ubuntu on a secondary hard drive, not realizing the Ubuntu was installing GRUB over my Windows 7/TrueCrypt MBR on my main hard drive.
