Never store data on RAID 0. You lose one drive, you lose everything as it is striped
and that's why it shows 500 gig, because RAID 0 is the total capacity of two drives
(250+250=500 gig).. It may be faster, but it's like stepping off a cliff with no
parachute. Where as RAID 1 is fault tolerant because the data is mirriored to the
second drive (250+250=250). It's slower but you have a parachute if you step off
the cliff. ;-) Therefore, if one drive fails, hopefully the other drive will survive
and your data is safe (known as fault tolerant).
RAID 0 needs a good back plan, no backup and your data is gone unless you have the
money to have it professionally recovered, and then there is still no assurance that
you can get anything back..
There is probably a reason your computer was off. If it didn't shut down properly,
for any reason, it can corrupt the drives, especially RAID drives, and hurt the HDD
in the process.
