hardware causing corruption on harddisk?
I recently had a machine come in that appeared to have a corrupt partition table. It was recognized in windows as unallocated. I imaged it just in case I screwed up and a coworker used a partition recovery utility that worked fine after repairing the mbr. I worked on the machine for about 3 hours and after rebooting it is back to the original state that i received it in. Any ideas?
This is just a repair job btw. not forensic work.
change ide cable use ata33
After my few moments of frustration I actually took time to think about the problem. After placing the data onto the new drive it and testing it for a few hours everything is fine. At the time i didnt think of it, but it appears that the problem was grown defects affecting the boot sector.
I used the image of the drive that I took after i rewrote the partition table and mbr. Luckily I did this before i started to patch the machine. The same problem happened after a few hours and I was not able to perform the same steps again.
Hardware can really cause problems on harddrives, i've had a problem with a computer running on a mains-plug without a ground connection. The most exotic problems arises from memory-faults (segfaults) to unbootable harddrives and kernel panics. So if you have problems on your powersupply or a bad mains, this could cause you some problems which on the first sight doesn't appear to come from your powersupply.
