lost capacity to RAID 0
|
|
|
| I had a raid 0 mirror with 2 30 gig drives. One died and all I had was a 40
gig to replace it. Now I want to start over and build a mirror with 2 40 gig
drives using the one 40 gig that was in the 30 gig RAID. The only problem is
that that 40 gig drive now only reads as 30 gig when I go to install a clean
Windows 2000 on it.
The question is how do I get a 40 gig drive that was altered by a 30 gig
RAID setup back to 40 gigs again?

Run the HD mfg's diagnostics in the mode where it writes all zeroes(writes
the whole drive with something) to the drive.

| Hank,
We hate to deliver the news but you're in a pickle now. Whenever you run a RAID 1 mirror (NOT RAID 0, Striped) the available space is equal to the smallest of the two drives in the array. Because the 40 Gb drive was mirrored to a 30 Gb drive the array controller defaulted to the smaller of the two drives. This is a general rule with RAID 1 mirroring but your particular array controller may have a specific workaround. Since the array controller masks this info from the OS you can't create a separate 10 Gb parition of non-mirrored data either. Details on the particular array controller might help.
Most likely you'll have to format, delete the partitions, and re-setup RAID 1 mirroring through the array controller. Given the falling prices for storage I'd recommending adding a secondary RAID 1 array with larger drives and moving your data to the new array; however, this is up to the budget to do so.
Keep in mind that even RAID 1 isn't foolproof...if a virus or configuration problem hit your system you'd still have hard luck.
Good backups are paramount...think of them as life insurance for your PC
