Hi, following your suggestion I used smartmon to get access to the SMART
data. I have run an extended offline test (with-t offline I think). The
test reported no error (!) and the bad sectors are now read/writeable
(!!). Is it safe to think the problem is gone?
# smartctl -l selftest /dev/ad10
=== START OF READ SMART DATA SECTION ===
SMART Self-test log structure revision number 1
Num Test_Description Status Remaining
# 1 Extended offline Completed without error 00% 458
# 2 Extended offline Aborted by host 70% 456
