Thanks for the hint, Michael. I've just checked the SMART status on
both disks and the 4kb drive looks indeed suspicious:
197 Current_Pending_Sector 0x0012 100 100 000 Old_age Always - 8
198 Offline_Uncorrectable 0x0010 100 100 000 Old_age Offline - 8
The 512 byte drive appears to be fine. But I'm running the long
SMART self test on both of them right now and will report back
the result in a few hours.
