Hi, When I ran eix hdf command, all of a sudden my usb drive started making weird noises. I only have ccache, distfiles and packaes directories on sda2, the usb disk partition. I don't know why eix waked up the disk. Eix hung there non-responding for a moment as the disk kept making noises, so I interrupted the task. Immediately checked the logs[0] and umounted the device as a reflex.
The time 20:38 in [0] corresponds to the time I issues eix. There was nothing in the logs for 8 minutes. The last operation I had on the disk was fetching kde updates which finished at about 19:00. I wanted to fsck the device and got: # fsck.ext3 -pvf /dev/sda2 fsck.ext3: Attempt to read block from filesystem resulted in short read while trying to open /dev/sda2 Could this be a zero-length partition? fdisk -l was not showing the device anymore. I could not mounted it back. Googling the subject brought some unsolved threads so far. There were some similar issues, one with ext4, one with ipod. But in all those cases they still had their device alive whereas I seem to completely lost it. Here is what smartmontools says: # smartctl -d /dev/sda smartctl version 5.38 [i686-pc-linux-gnu] Copyright (C) 2002-8 Bruce Allen Home page is http://smartmontools.sourceforge.net/ =======> INVALID ARGUMENT TO -d: /dev/sda =======> VALID ARGUMENTS ARE: ata, scsi, marvell, sat, 3ware,N, hpt,L/M/N cciss,N <======= Use smartctl -h to get a usage summary 21:08:23 | log # smartctl -a /dev/sda smartctl version 5.38 [i686-pc-linux-gnu] Copyright (C) 2002-8 Bruce Allen Home page is http://smartmontools.sourceforge.net/ Device: WD Version: 1.02 >> Terminate command early due to bad response to IEC mode page A mandatory SMART command failed: exiting.

And this is the messages I get upon plugging[1]. For comparison here is usual message I got last time mounted[2] I am not sure what may have caused the issue but there are two things I suspect that may have caused this. 1. I usually forget the device is mounted and sda1 partition swappedon while suspending/sleeping the system. I run fsck.ext3 on the complaining dirty partitions. 2. I accidentally ran grub-install /dev/sda instead of /dev/hda last week and interrupted immediately. There is no sign of a problem in the logs for a week. I had install grub on sda couple of years ago but hadnt used it for a long time. I thought this may be related because interrupting the grub-install left in complete mbr. So I ran grub-install on sda again but it could not find the disk[3]. I cannot think of anything else to try. I hope you can suggest me a way to recover the device or to extract data from it.
