[QUOTE="Alexdr, post: 629436, member: 62084"] I'm crossposting from Wilders to hit a broader spectrum of people. One thing I did forget to state there is that, when I get to the recovery tools part in the story below, I tried sfc /scannow, it finds something but can't fix it until next boot. Thus, I reboot, but it's the BSOD junk so it never gets a chance to really fix it. Similarly, I try doing CHKDSK, but you can't CHKDSK a RAW drive (as detailed below). I just wanted to post this thread in hopes someone would have some guidance. Last week, my laptop of a few years had its battery die. I.e., I woke up, went to the laptop and found it to be off. It wouldn't turn on except when I took out the battery and kept it plugged in with the AC adapter. Later that day, I shutdown the computer--at this point I'm just speculating--and then, I think, I pulled out the power cable too soon (I was packing up the laptop) such that it had an unexpected shut off (especially since no battery) while doing Windows shutdown processes. As a result, when I turned my laptop back on (with AC adapter connected), I went through the TrueCrypt screen to put in my password and then got stuck in a BSOD loop. It's the one that occurs after starting Windows and says "UNMOUNTABLE_BOOT_VOLUME". At this point, I though, OK, use recovery tools. I proceeded to tap F8 after typing in my TC password and got to the recovery screen. I ran the recovery screens "try to fix things" command, rebooted, didn't fix it. I then, from the CMD in the recovery module, ran diskpart to see what was up. I found my drive was now labeled as RAW (not NTFS). At this point, I felt that I probably ruined something in the boot sector. I proceeded to run bootrec /fixboot. I rebooted, that didn't fix anything (surprisingly it still worked if I remembered correctly, i.e. it was the BSOD that killed me). I then went back into recovery tools, ran bootrec /fixboot and then bootrec /fixmbr and then rebooted. This is where things went bad. I would turn on the computer and wouldn't even get the TC password prompt. My default thought was that, in fixing the MBR I overwrote something related to the TC header or the Windows header. I proceeded to get my TC Rescue disk. Instead of trying to regain the TC or System header from the TC rescue disk, I immediately ran "Decrypt everything". It was going pretty quick (supposedly only one day to decrypt), however, upon awaking the next day, I found it stopped asking "Read error: 16 bad drive 0: sector 12652XXXXXXX" skip all bad blocks?
