Hi, recently my pc lost power and when I tried to start it up 2 of my 3 hard drives didn't work anymore. The hard drives are in a RAID-0 configuration. When I go to disk management it says it is an unallocated disk and when I try to initialize it it says: Data error (cyclic redundancy check). I am using Windows 8.1 Pro.
Can anyone help me?

You're experiencing read errors due to instability(electronic or mechanical) of the read/write heads.
Bit error defects over time can have similar symptoms but, considering it happened after an abrupt power down, it's most likely that you've got a case of head bounce(mechanical damage to the heads/media).

Do you have any data you need to keep on the drives?
Do you have a backup of all your data?

Hi, thanks for the reply. No there are no important files on the disks just games so I haven't got a backup. So it's time for me to buy a new hard drive?
