disk "shrunk" after going into a 2850

[Patrick_Boyd at Dell.com]

The controller writes metadata at the end of the drive so that it knows
what type of RAID it is and can match it up to other drives in its set.
This is a fairly normal RAID practice and there really isn't anything
you can do to get back the extra space at the end of the drive.

Update:

The disk shows up in the RAID controller BIOS as the same size as the
drive that was in the slot previously, despite the drives having
different sizes.  I tried deleting the logical volume, removing the
drive, and power-cycling the machine.  No luck- attempting to add it
back shows the same incorrect size.  How do I get the controller to
see the proper size of the drive?  This is a PERC 4e/Di.

Also, I mistakenly removed a single unformatted drive that was in its
own logical volume.  What do I need to do to convince the controller
it hasn't "failed"? (I "fail" to see how a single drive can become
inconsistent with itself, especially while not in an OS but rather,
the raid controller's BIOS.)
