[CentOS] hda dma seek errors

I am getting occasional seek error on my boot drive.
The messages are as follows:

pshda: dma_intr: status = 0x51 { Drive ReadySeekComplete Error }
  hda: dma_intr: error= 0x84 { DriveStatusError BadCRC }
  ide: failed opcode was: unknown

Everything seems to be working fine but these errors do
have me concerned.

The last time they occurred I was created a fairly large cpio
backup file in the '/tmp' directory.

The drive has been checked via fsck, and any errors found were
reported to be corrected.

Should I take some kind of action on this, or just ignore the errors?
