While using the computer, I had got a "KERNEL_DATA_INPAGE_ERROR". The disk had failed to respond when it was trying to make a minidump. Now, the HDD has gone missing. It has disappeared from the BIOS. I'll try wiggling the sata data cables around, which is going to be a huge pita since the computer is a small from-factor. Worst case scenario would be the hdd is so screwed up that i'm unable to salvage any data from it. Any suggestions of what to do?
