Momentus XT, Momentus, Momentus Thin, MobileMax, and other notebook drives

[MDUR]

We've deployed several dozen Dell Latitude E6420s with Momentus Thin drives, model ST320LT014-97K142.

After a machine has several days of uptime, the drive slows to a complete crawl, with the slowness persisting through reboot. (For reference, a laptop that has been up for five days, upon reboot, may take 20-30 minutes to reboot.) The issue persists until the machine is completely powered off (e.g. power removed from the drive).

Diagnostics all come back normal, and the first several days of operation work as expected with read speeds of close to 100 MB/sec average.

The drives are almost all encrypted, but we've seen the issue occur with drives that do not have our encryption software installed (Wave Eras, for reference).

The issue seems to be the same as another user is experiencing: http://forums.seagate.com/t5/Momentus-XT-Momentus-Momentus/Momentus-Thin-XT250LT007-slows-after-a-co... save that he is using standard models of the drive, whereas we're using the self-encryptables.

We've updated drivers and BIOS to the latest versions to no avail. Any help would be great.

Customer services for that one mate, slowing to a crawl can be your memory is filling up and not getting released when it should, anyway it's highly unlikely you will get a fix here with it, although a full run down of what you've installed and flashed may help.

dell latitude 6520

the factory load has been cleared (OEM Partition too) I am having the same issue, the only thing that fixes it is a power off (reboot does nothing to fix it) looking at the firmware version that looks like a Dell version (>__>) I signed up just for this issue to chime is too. I have checked a couple of the other laptops we got (same drive) same issue, dell load or not.
