Unable to partition or format array

The Reserve Sector of one of the drives has become corrupted or bad. Removing the

Reserve Sector will remedy any issue related directly to a Bad Reserve Sector.

WARNING: Before removing the Reserve Sector of any drive(s), backup all

existing data. Removing the reserve sector of a drive permanently delete all

existing data from the hard drive. For Mirrored arrays (RAID 1), you should

remove the Reserve Sector from the "mirrored" drive first (this will appear during

Step 3 below) then rebuild the mirrored array. Remove the sector from 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. When the system boots, press <Crtl-F> to enter FastBuild.

2. Press <2> to "View Drive Assignments".

3. Using the arrow keys, highlight the drive you wish the reserve sector removed.

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

5. Press <Ctrl-Tab>. A message will appear informing you that the reserved sector (which

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

6. Press <Y> to confirm.

7. For mirrored arrays, hit the <Esc> key twice to reboot and skip to step 10.

8. For striped arrays, repeat this process for each member of the particular array that is

having a problem.

9. Once you’re done, hit the <Esc> key twice to reboot.

10. After rebooting, use FastBuild to re-create the array. For mirrored arrays, rebuild the

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

FastCheck’s Options window.
