Go to SolutionHow to Wipe HDD
On a PE1950 with the standard PERC 6/i what is the best way to wipe the hard drives before returning it to DELL Leasing ? I have used the DBAN ISO in the past to perform this, but apparently this tool no longer supports RAID drives. Does anyone have a good alternative ?
If you have 2 or more physical harddrives, one option would be to:
- create a raid 0 from all drives and let the controller initialize the virtual disk
- then destroy and create a raid 1 (if it's just 2 physical drives) or raid 5 (if it's 3 or more drives) and let this initialize
- go back and forth several times with full initialization and your data should be (next to) impossible to recover by a next user/owner of the system

One option might be to create a raid set, boot to a Linux Live CD and use "dd" to write random data to a disk. Some info on this can be found in this Wikipedia article. Check specifically the "dd if=/dev/urandom of=/dev/hda" command. On a raid controller, this will probably be "/dev/sda" instead of "dev/hda" though, but the rest should be the same.
You can download Ubuntu desktop or so for a Linux Live option (I don't know for sure if it will have native raid controller drivers for your PERC, but it probably will have them).
