Hello,
I personally do not know the answer to your question, but as long they
are corrected errors and not more than 0.1% of the reads/writes and
there are no uncorrected errors and no tape alerts, I would imagine it
is OK.
Here is what I get on my LTO-5 drive. It is a reconditioned drive that
I installed about 2 months ago, so it does not have a terribly long history:
root@groschat:/home/kern# smartctl -H -l error /dev/sg0
smartctl 6.5 2016-01-24 r4214 [x86_64-linux-4.4.0-78-generic] (local build)

=== START OF READ SMART DATA SECTION ===
TapeAlert: OK
Error counter log:
Errors Corrected by Total Correction

ECC rereads/ errors algorithm

bytes] errors
read: 2 0 0 0 2
0.000 0
write: 1337 0 0 0 3416
0.000 0
I would be curious to hear what statistics Alan Brown has since he make
very heavy use of his drives.
Best regards,
Kern

Hi,
Below is the SMART TapeAlert output I received after running btape 'test' and
'speed' tests on a new IBM ULTRIUM-HH5 LTO-5 drive using brand new Fujifilm
tape. Is it normal to see 40 (corrected) errors per few GBs of data that the
tests have written to tape?
$ smartctl -H -l error /dev/sgtape1
