Lost disk signature
Posted on 2006-05-03
Dell PERC 3/Si controller
Seagate Cheetah ST336607LC SCSI U320 HDD (hotswap job)
WINNT 4 SBS (ARGH!)
We have (had?) the above server in a branch office, and it has just died. Further inspection reveals the boot drive has failed, and the system will no longer boot. All data (files/exchange .edbs) are stored on a separate disk that had no problems.
No problem with that, not bothered about the system as i can reinstall it, but the data is obviously vitally important. Booted into KNOPPIX linux from CD, it mounted up the remaining scsi drive (data disk) and allowed me to view the files no problem.
For vairous reasons (lack of knowledge of linux, and my inability to mount a 250GB USB HDD in knoppix), I took the disk out and put it into another server with the same drive caddys, running windows 2000 svr. Disk was detected fine by scsi/raid card, and windows 2000 svr recognised the disk fine.
Problem is, like an idiot, I hit the dreaded 'Yes' button on the 'Write Signature to new disk?" popup. I now have a disk with 35GB of data on it (i hope!), but it shows up as 'unallocated' in windows 2000, and now the PERC controller in the original server doesn't recognise the volume on the disk (presumably as the config has been overwritten by the win2k disk signature).
Short of sending the disk off and paying for professional DR, is there any way I can get the disk working again (in any operating system!) so i can copy the data off? When I plug it into the PERC card on original server, the PERC card boots and says 'no volumes detected'. PERC utilities recognise the disk, and gives me the options of formatting or initialising.
