This report looks very familiar to me. I installed Ubuntu 9.04 on a USB stick to boot it from a Dell D520 laptop, and after a day or so the device just went off, usually during Nautilus use: the desktop reported resources to be unavailable. At first, rebooting was possible, but after a while it would happen again. Finally, the USB stick did not boot anymore, and was fully destroyed, No PC / OS will recognize it anymore. I blamed it on the stick (OCZ Technology, 32G ), which I plan to return to the seller shortly. No I installed Ubuntu 9.04 on a USB external disk (Plextor 160GB). Again, after a few days using it on the Dell D520 laptop, the device just went off. I shut it down immediately and did not reboot until yesterday evening. Then, I tried to boot one more time on the Dell D520, but it failed during logon. After that, I booted from the USB disk on my old Dell D600 laptop. It worked, but took a lot of time, and very heavy disk use, judged by the activity display on the disk. After shutting down an rebooting a few times the device now works good on the D600.
After this experience, it seems to me there's a serious problem in the combination of Ubuntu (9.04 in my case) and Dell D520 where the USB is quite heavily used (as the USB device is used as the boot harddisk). In the next days, I will do some more testing on the USB external hard disk, and boot it on my new desktop replacing HP Compaq 6830s laptop. Then I will attach some the syslogs - from the USB external disk, not from the late USB stick. I'm not an expert on that level, but I hope thes syslogs may throw some light on the problem. Googling around, I also found this link http://ubuntuforums.org/archive/index.php/t-795327.html, about agressive power management beating up harddisks on - amongst many others - the D520 laptop. Although USB is not the target in this discussion, it might be related. ** Changed in: gnome-volume-manager (Ubuntu) Status: Invalid => New -- Ubuntu destroys filesystem on attached USB harddrive! https://bugs.launchpad.net/bugs/68824 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
