Hello,
First of all thanks to all the developers of smartmontools and
apologies for the length of following message. I have noticed two
problems which I have outlined below, followed by various information
and logs from the system.
== Unable to run offline selftests on SATA OCZ vertex SSD ==
I have compiled the latest smartctl from SVN trunk in order to test a
possibly failing OCZ-VERTEX SSD.
I've read lots of previous messages on this mailing list and on the
ocz forum which explain that the meaning of smart attributes on SSDs
is still in flux, but I am having difficulty even running the self
tests.
I tried the following commands to initiate background selftests
* smartctl -t short /dev/sdb
* smartctl -t long /dev/sdb
Neither of these work - when I subsequently run...
* smartctl -l selftest /dev/sdb
...to monitor the progress of the test, it always reports "Aborted by host"
If instead I run in "captive" mode, the tests run in foreground mode
and when they complete I can view the test results using -l selftest
The short test results tell me that errors have been encountered at
various LBA offsets.
The long test results tell me that the no errors were found.

This device does seem to be faulty. It is mounted in Linux with a
Reiser filesystem and used a cache storage partition for a busy Squid
proxy server. It operates in a cluster with two other identically
specified devices - neither of which display any problems.
The visible symptoms are that after a period of time, Squid reports
corruptions in the files it reads from the partition on that SSD,
shortly afterwards, reiser FS reports corruptions and remounts the
partition readonly.
So my questions are:
* can I trust the self test results from this device?
* is there any further information I can provide which will help
improve the smartmontools support for this device? eg
{{{
Warning: device does not support Error Logging
Warning! SMART ATA Error Log Structure error: invalid SMART checksum.
SMART Error Log Version: 1
No Errors Logged
}}]
* which SSD devices are best supported by smartmontools?
== Kernel loses contact with first of two SATA SSD devices after
smartctl offline scan ==
* I also encounter different problems when I attempt a Captive test
of the another SSD installed in this system - the kernel driver
appears to lose contact with the device until the system is rebooted.
Has anyone got any ideas what might be the cause of this?
