I have been having issues with my old primary hard disk. Basically after being booted for a few minutes any program accessing locks up for several minutes and then dies. At this point the hard disk dissapears from the device manager. When it was running windows this would be followed promptly by a BSOD and a reboot in which the disk was missing from the bios. After a few minutes of the computer not running the disk will appear again and I can access it a little more, though the time and amount of data I can get off it seems to be reducing.
I no longer boot windows from this disk and have been trying to understand the problem to maximise my potential to get the data off the disk before discarding it and have been using HDD sentinal to do this.
This article http://www.hdsentinel.com/hard_disk_case_weak_sectors.php makes a case that potentially I have no problem with the disk and that running a Reinitialise Disk Surface Test will potentially fix my problems.
This forum http://www.bleepingcomputer.com/forums/t/509928/bad-and-weak-sectors/ suggests otherwise and states it is a very long running test.
My concern is that I could kill the disk trying to do such repairs and also the case scenario covered by HDD sentinel does not mention anything about the disk hanging and disappearing off both the disk manager, device manager and bios/
This lead me to believe it could be overheating, though it failed at under 35degrees which is not that hot. It also makes me wonder if the circuitry was the issue, since when I do access data, it copies fast and perfectly well right up till the point where it hangs (copying and accessing applications stop responding).
I tried isolating the drive into an older computer with completely different hardware though this did not help. Also there have recently been a few improper power downs which could have excerbated issues.
Finally this disk has beeb causing me problems for a while. With it causing the OS to hang for 30-60 seconds at a time while trying to access data, though it has always recovered perfectly well in the past and never caused BSOD issues before.
I tried making an image of the disk using disk2vhd, though it would not even start reading the affected partitions, though an offline tool might prove more effective.
Attached are the images of the drive state as reported by HDD Sentinel. It tells me I have a 4% health disk and:
"There are 417 bad sectors on the disk surface. The contents of these sectors were moved to the spare area. The drive found 2751 bad sectors during its self test.
There are 2751 weak sectors found on the disk surface. They may be remapped any time in the later use of the disk.
65535" (256^2 or the max for the counter probably) "errors occured during data transfer. This may indicate problem of the device or with data/power cables. It is recommended to examine and replace cables if possible. It is recommended to examine the log of the disk regularly. All new problems found will be logged there."
Basically I am looking for advice on where to go next.
Sound I try and make an image another way, try and fix the disk, or just continually boot and copy files off with shell scripts untill it finally dies? Any advice is appreciated.
Edit: For the record the disk is a Seagate Barracuda 7200.10 3.AAE 750GB. It is also a repaired HDD.
Also to help out those giving help my level of experience is that of a software developer. (yes I should know better than not having backed up data).
