I have Win XP Home on one HD, and an NTFS backup partition and SUSE 10.0 on another HD. Both OS's work fine, but PartitionMagic 8.0 gives me this error:

PowerQuest PartitionMagic has detected an error 116 on the partition starting at sector 62251875 on disk 2.

The starting LBA value is 62251875 and the CHS value is 15483824.
The LBA and CHS values must be equal.
PowerQuest PartitionMagic has verified that the LBA value is correct and can fix the CHS value.

Would you like PowerQuest PartitionMagic to fix this error?

I'm inclined to take the "if it ain't broke, don't fix it" approach here, but could this cause a problem in the future? What's causing this error? Should I be worried?
