Answer

A corrupted IDE RAID 1 could occur when the server is not properly shut down. In such a case, you may experience some of the following symptoms.

• The disk array becomes non-bootable.
• The server performance becomes extremely sluggish.
• Windows logs a large number of controller error / time-out events.

A corrupted IDE RAID 1 does not necessary mean corrupted data. Take the following steps to determine if the array is recoverable.

• Power off and disconnect both drives from the Adaptec 1200A controller
• Connect drive 1 directly to the SBC
• Power on. The drive can be used to rebuild the array if the system boots successfully
• If drive 1 does not boot, connect drive 2 to the SBC and repeat the above step

To rebuild the array:

• Destroy the Mirroring Relationship
• Reconnect the drive containing good data to IDE 1 of the 1200A controller
• Reconnect the other drive to IDE 2
• Make sure drive 1 is set to bootable in the Adaptec BIOS
• Continue to Boot o Windows
• Delete the partition on drive 2 if necessary
• Use the Adaptec Array Management application to rebuid the array
