Unallocated disk with cyclic redundancy check

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?
  2. yes, buy another disk and restore from backup.

    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?
