Hi,Background: I have had a power supply unit failure and as a result the PCBs of three hard drives were fried as well as the processor.
I have replaced the PCB from an identical drive for the data drive, a WD200EB-00CSF0. The harddrive is seems to work fine for almost all files: It can be mounted, data is generally accessible, etc.
When I try to image the drive with ddrescue, it proceeds without errors within 20 minutes to 16.5Gb/20Gb where it encounters the first errors. It then takes approximately another 5-10 minutes apparently only getting errors before finally crashing the whole system.
A photograph of the screen can be seen here: (Sorry for the flash...) http://img64.imageshack.us/img64/745/crasho.jpg The result is the same with: ddrescue -n ddrescue --direct ddrescue --rawAll attempts were made in runlevel 1 on a Centos 5.4 system with kernel 2.8.18. Resuming recovery with the log file makes the system crash shortly after resuming.
Can anybody tell me how to either:- read out a complete image (obviously without the presumably bad sectors) so that I can run file system recovery? The image now is truncated.
- fix the hard drive problem? (I.e. why should the hard drive have bad sectors in the last few GB given a mere power surge?)
Many thanks for any help! - Arik _______________________________________________ Bug-ddrescue mailing list Bug-ddrescue@gnu.org http://lists.gnu.org/mailman/listinfo/bug-ddrescue
