    I was using the ext4 filesystem.

    I let this issue rest for a while since I was too lazy to try anything like flashing my bios and upgrading the firmware required a windows machine(OCZ is working on a linux flasher).

    Anyway, it seems the issue is related to the drive and also happens to people using windows 7. I found this thread on the OCZ forums, OCZ apparently is looking at the issue right now, I think I'll return my drive when they've responded.

    Noone has mentioned the most important detail here.

    What filesystem are you using on the system experiencing this?

    I have exactly the same problem.

    And I am using Arch Linux...

    I even installed it new, with new partitions, new file systems.

    Then I rebooted... into my brand new repartitioned system.

    I turned the laptop (!) off, on... and then I was at the same position with a fully installed system which i had before repartitioning! Oo

    Notebook Model: HP 6555b

    SSD: OCZ Vertex 2 50GB

    Damn it.. I can send it back within one week. When there is no solution here, i'll do so.

    I guess you are trapped int time-space singularity. May the force be with you

    Definitely try a different distro!
    This is of crucial importance.

    As I suggested, laptop mode could be screwing you.

    Please note that you could DEFINITELY and EASILY be running the whole thing out of cache! In LINUX, your entire MAIN MEMORY can be used as a disk cache for improved performance. As memory is needed for normal operations, disk cache is dumped to make room.

    Obviously there is no synchronization going on, and LAPTOP MODE is one of a few things that could be to blame.

    You *MUST* try a different distro in case it is a ubuntu-specific problem that is attacking you, i.e. if you have laptop mode set to spin the disk down and never sync, then the filesystem could be ENTIRELY in main memory!

    Also make sure that you have the latest firmware installed to the SSD.

    I appear to be having the same problem with a new ThinkPad Edge. I bought an OCZ Vertex 2 60GB SSD. I have, twice now, installed Ubuntu 10 on it via USB which goes perfectly, except when I do any kind of restart nothing is saved. No updates, no wifi settings, and back to default desktop background.

    I initially also had some boot hangs and issues which appear to have mysteriously disappeared, although I haven't actually updated the BIOS yet or anything. If I run the hdd diagnostics program from the BIOS on the SSD it fails- but I can still boot from it!

    If I plug it in to the USB through an enclosure it doesn't show up on Ubuntu 10 as a drive (nor does the light appear on the enclosure).

    Although the two queries are slightly different, I'm thinking it is something to do with the actual drive, rather than the way Ubuntu is using it.

    The next step I plan to take is to try a different distro on the SSD and chuck it back inside the laptop.

    By powering off I mean a clean shutdown. The weird thing is that it always goes back to the same state(where I have only chrome installed and one wireless network configured).

    Rebooting and then powering off doesn't change anything. I didn't try another distro. I did try installing ubuntu 10.10 alpha 3. After a reboot it was still there, but after a clean power off my system was back at ubuntu 10.04.

    I can't imagine an entire OS would be stored in some kind of cache and removed after a power off, but still this is what seems to be happening.

    Either I'm being stupid and overlooking something obvious, or this is a very weird problem.

    Obviously, something isn't syncing right.

    One thing that confuses me about the problem... you say that REBOOTING keeps data, but powering off loses it. How about rebooting and THEN powering off?

    How about syncing the filesystem and then powering off?

    How are you powering off? Clean shutdown? Or by force (i.e. holding power button for 5 seconds, pulling wire and battery, etc.)? Reason I ask is that a clean shutdown SHOULD sync the filesystem.

    Could be an issue with laptop-mode, might not be syncing the buffer to disk as required, maybe a bad interaction with the SSD....

    Have you tried a different distro? Or just Ubuntu? Could be a problem with that distro.
