disk "shrunk" after going into a 2850

After moving a disk from a different system without a raid controller,
to a 2850 with the PERC4E/Di, we mounted it read-only for some tests.
I had to create a single-drive RAID0 array for that slot to see the
drive.
One of the tests involved making a read-write copy elsewhere. Imagine
my surprise when ext3 spits up a bunch of messages about trying to
read past the device. "Huh?"
Sure enough, fdisk (in sector units mode) shows that the drive very
obviously "shrunk" on the trip over from the server room, as the drive
is now supposedly smaller than the partition.
Disk /dev/sdc: 146.6 GB, 146695782400 bytes
255 heads, 63 sectors/track, 17834 cylinders, total 286515200 sectors
Units = sectors of 1 * 512 = 512 bytes
Device Boot Start End Blocks Id System
/dev/sdc1 63 286744184 143372061 83 Linux
What seems more likely is that the raid controller decided to only
show part of the array. Any ideas on how to see "all" of my drive?
