Replace failed hard drive

hmm, well its been a good 10 years since iv'e done it, but when i was using raid controllers, it would be an option in the bios of the controller card. if you have a built in raid controller, i would check the bios, if not, check the raid software that came with it.

You may need to download the raid software.
From the manual:
http://support.dell.com/support/edocs/systems/xps400/om...

"If your computer does not have a spare hard drive, and the computer has reported a degraded
RAID level 1 volume, you can manually rebuild the computer’s redundancy mirror to a new hard
drive by performing the following steps:
1 Click the Start button and point to Programs→ Intel(R) Application Accelerator→ Intel
Matrix Storage Manager to launch the Intel® Storage Utility.
2 Right-click the available hard drive to which you want to rebuild the RAID level 1 volume,
and click Rebuild to this Disk."

should be an option in the RAID Bios

Thanks to all. I got it.
