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. -- Markus _______________________________________________ xfs mailing list xfs@oss.sgi.com http://oss.sgi.com/mailman/listinfo/xfs
