In order of most likely to least likely:
- replace the disk
- replace the cabling to the disk
- replace the disk controller
- replace the power supply
You can scan for bad blocks with the badblocks tool, but if you
have repeated problems like this, the disk is probably not reliable.
If you need your data to survive events like this later in the
disk's life, you will need backups, RAID, ZFS, or similar
measures.
