I installed Ubuntu the external harddisk with the default filesystem ext3. On august 9, 2009 I converted the file system to ext2. Since that moment, I've been using the hard disk quite intensively on the Dell D520 (the one that destroyed my usb flash drive and almost destroyed the usb hard drive). It looks like this has solved the problem, I have had no trouble at all since then.
So it seems the work around for this problem is not using a journaling file system for an external usb device. I will add this comment to the bug, too, including a link to the recent \var\log directory I'm attaching to this comment. ** Attachment added: "\var\log contents created August 14th 2009, after converting ext3 to ext2 filesystem on August 8th 2009." http://launchpadlibrarian.net/30338275/log_090814.gz -- 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 ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
