I have however a question: How do I verify that a hard-drive is accurately working if its firmware will hide the bad sectors as long as possible?

I think the smartctl program from ports/smartmontools is a good tool for such verification. As far as I understood,
it can read internal error logs from the firmware.

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

SMART Self-test log structure revision number 1
Num Test_Description Status Remaining LifeTime(hours) LBA_of_first_error # 1 Extended offline Completed without error 00% 458 -
# 2  Extended offline    Aborted by host               70%       456
