Unable to Partition or Format Array

This condition may occur when the Reserve Sector of one of the drives has
become corrupt or bad. Removing the Reserve Sector will remedy any issue
related directly to a Bad Reserve Sector.

Warning

Before removing the Reserve Sector of the drive(s), backup
any existing data. Removal of the reserve sector of any
drive permanently deletes all existing data on the hard
drive.

For Mirrored arrays (RAID 1), remove the Reserve Sector from the mirrored
drive first (this will appear during Step 3 below) then rebuild the mirrored array.
Remove the Sector on the Master Drive only as a last resort.

For Striped arrays (RAID 0), removing the Reserve Sector from any of the drives
that are striped will destroy the arrayed data.

To remove the Reserve Sector, follow these steps:

1. During boot up, press Ctrl-F to enter the FastBuild BIOS utility.

2. Choose option 2, View Drive Assignments.

3. Press arrow keys to highlight the drive where you wish to remove the

reserve sector.

4. Press Alt-F1. The highlighted drive will start blinking on the screen.

5. Press Ctrl-Tab. A message will appear that says the reserved sector (which

is where array information is kept) on the disk will be wiped.

6. Press Y to confirm.

7. Take the appropriate action:

•

For striped arrays, repeat this process for each member of the
particular array that is having a problem. When you are finished, press
the Esc key twice to reboot.

•

For mirrored arrays, hit the Esc key twice to reboot.

8. After rebooting, use FastBuild to re-create the array.

•

For striped arrays, use FDISK and FORMAT after setting up the array.

•

For mirrored arrays, rebuild the mirrored array.
