It could be that the drive is actually OK but that sector just got mis-written (due to a hard power-off while it was being written, perhaps) and will be fine once it gets written successfully. You could try using hdparm commands to overwrite that sector, or just boot from a live CD, zero out the entire disk with "dd if=/dev/zero of=/dev/sda" and try a reinstall. If the drives go away and a long SMART self test reports no errors, the drive is likely OK. If not, a replacement is likely in order. > 198 Offline_Uncorrectable 0x0030 100 253 000 Old_age Offline - 0 > 199 UDMA_CRC_Error_Count 0x0032 200 200 000 Old_age Always - 0 > 200 Multi_Zone_Error_Rate 0x0008 100 253 000 Old_age Offline - 0 > > SMART Error Log Version: 1 > No Errors Logged > > SMART Self-test log structure revision number 1 > Num Test_Description Status Remaining LifeTime(hours) LBA_of_first_error > # 1 Extended offline Interrupted (host reset) 80% 1 - > > SMART Selective self-test log data structure revision number 1 > SPAN MIN_LBA MAX_LBA CURRENT_TEST_STATUS > 1 0 0 Not_testing > 2 0 0 Not_testing > 3 0 0 Not_testing > 4 0 0 Not_testing > 5 0 0 Not_testing > Selective self-test flags (0x0): > After scanning selected spans, do NOT read-scan remainder of disk. > If Selective self-test is pending on power-up, resume after 0 minute delay. > > [root@bxtest ~]# > > > Any help would be appreciated.
