This sounds similar to a problem that I experienced yesterday. I did a fresh installation of Ubuntu 9.04 recently and formatted every partition to ext4. Yesterday, I was moving huge video files from my home directory to a removable USB hard disk (formatted to ext4 as well) when the system froze permanently (i.e. all hard disks stopped running completely). I did this with a couple of my other removable USB hard disks and the same thing happened many times.
The problem can be replicated by copying or moving files within the same IDE hard disk as well. Just a while ago, the system froze when I emptied Trash. The computer has Windows XP installed, and no such problem problem occurs when I'm running it. However, as far as I know, I have not experienced any data loss. -- Ubuntu hangs up from time to time when I try to copy files from ATA NTFS to SATA ext4 partition https://bugs.launchpad.net/bugs/390204 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
