Question External hdd Not Recognized


HP Pavillion hdd crashed in my daughters computer so I removed it and purchased a 2.5 USB 2.0 IDE Drive Enclosure and connected it to my laptop Asus Eeee running Ubuntu 9.10. I need to get access to the files on the external hdd and nothing seems to recognize except Palimpsest says:
Hard Disk 811 ATA/ATAPI Device
Unknown Size
Unrecognized
Smart Not Available
/dev/sdb

When I open a terminal and run:
rhg@rhg-laptop:~$ sudo parted /dev/sdb
rhg@rhg-laptop:~$ sudo gpart /dev/sdb
Floating point exception
rhg@rhg-laptop:~$

When I run Test Disk:
Test Disk 6.11, Data Recovery Utility, April 2009
Christophe GRENIER <grenier@cgsecurity.org>
http://www.cgsecurity.org

Select a media (use Arrow keys, then press Enter):
Disk /dev/sda - 160 GB / 149 GiB - ATA ST9160310AS

It only recognizes the hdd in my Asus.

So if the Ubuntu Disk utility can see the drive how to I get these tools to see it?
I know for a fact the OS on the external hdd is Ubuntu 9.04 ext3 because I set this system up for my daughter. The gpu chip melted onto her HP motherboard and crashed her system. Now to add more excitement to this puzzle, the external hdd does have the Captain Hook and the Aligator loud Tick Tock sound when you first plug it in so the hdd is not the healthiest either.

OK, you want to "access" the drive, so you can recover files from it. If this is correct, I question why you are attempting to start 'parted'. Maybe just as a test to try to 'see' the drive? Ok...

So, with the drive connected, what do these show, if anything:

shell# fdisk -l #(note that's a lowercase 'L')
shell# lsscsi -v
shell# lsusb -v

And, I'm not certain, but is the command you used above, 'gpart', actually a command? On my system, Gparted is called "gparted" -- I'm just curious.

And, if the drive is making the sounds you describe,it may be really screwed, so be prepared to not get *anything* from it for free (as in, without professional data recovery).

External hdd Not Recognized

Sasha GrapefruiTgirl,
First off thanks for pulling in and taking a look at my issue and not just doing a drive by!! Yes, I'm trying to see the files on the external hdd to get a file off there for my daughter. She is putting her writing portfolio together to prove to the University she can write and one of her papers is on this drive. I agree Tick Tock is not good and I suspect its dead, but I thought I would give it a try.

Regarding gpart, it's identified in the Ubuntu Data Recovery Documentation. It explains that the gpart program scans drives and tries to re-create a partition table based on guesses.

Results from fdisk -l:
rhg@rhg-laptop:~$ fdisk -l

Results from lsscsi -v:

No command 'lsscsl' found, did you mean:

I was encouraged when lsscsi -v saw the external hdd, but where do I go from here?
Thanks again,

Yes.. So, the device is seen, as /dev/sdb, that's a good sign, though not surprising -- the drive hasn't physically exploded, so it's still functioning enough to be identified as the HDD that it is.

What I would do if I were trying to recover data from it, is try to mount it read-only.

Big Fat Disclaimer: I'm not a forensics expert by any means. I'm just telling you what I would do. Use at own risk.

So, As I was saying, I would try to mount it, and if that worked, I'd quickly navigate to the file(s) I want to recover, and copy them back over to a good HDD. Also, I'd be sure to do everything with root priveleges so I didn't run into any permissions errors. As you are also using Ubuntu, this probably means using `sudo` for everything.

Now, the way things often work, is that the DEVICE is /dev/sdb but each PARTITION is numbered; so, if there happen to be two partitions on the drive for example, you'd have /dev/sdb1 and /dev/sdb2.

Let's assume /dev/sdb1 is the ext3 partition you want to mount and try recovering stuff from. And, let's say you have a folder on your GOOD system that we'll use as a mount point, called /mnt/point

shell# sudo mount /dev/sdb1 -t ext3 /mnt/point -o ro

Above should mount the partition, if it is possible to mount. Change /mnt/point to whatever actual folder on your good system, that you want to mount the partition on.

If that works, it should say nothing on the screen. You can type mount to see that it mounted. If it gives errors trying to mount the partition, show us the errors.

Once this is done, navigate around in /mnt/point/<wherever> however you like (nautilus, mc, command-line...) to try to locate the files you want to recover, and copy them to somewhere back on your good drive.

When all done, navigate out of the partition so you can unmount it:

shell# sudo umount /dev/sdb1

And that's that.

PS - I'm not sure what the situation nmight be if there were only ONE partition on the drive -- would it be /dev/sdb or /dev/sdb1.

PS2 - If you try mounting /dev/sdb1,2,3,4,5 or whatever numbers, and you keep getting "no such device" or "blah is not a valid block device", we'll have more fiddling ahead.

PS3 - If we cannot possibly get the partition(s) to mount, you might consider the `dd` tool, to try doing a raw copy of the drive over to a safe location of equal size; I've never done this, but if it gets to this point, lots of other folks here HAVE done this, so someone else will be able to offer advice with that.

PS4 - I find it very weird that `fdisk -l` showed nothing at all. Maybe you should have used `sudo` there too?

Best of luck!
Sasha

External hdd Not Recognized

Sasha, I feel like this little hdd has thrown down the gauntlet, "Ha, just try to break me" If they could talk that is!! Ok here is the print out:

rhg@rhg-laptop:~$ sudo fdisk -l

Disk /dev/sda: 160.0 GB, 160041885696 bytes
255 heads, 63 sectors/track, 19457 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x92e4538c

Device Boot Start End Blocks Id System
/dev/sda1 * 1 2490 20000893+ 83 Linux
/dev/sda2 2491 19457 136287427+ 5 Extended
/dev/sda5 18709 19457 6016311 82 Linux swap / Solaris
/dev/sda6 4981 18708 110270097 83 Linux
/dev/sda7 2491 4980 20000862 83 Linux

Partition table entries are not in disk order

fdisk only saw my Asus Eeee not the external hdd

rhg@rhg-laptop:~$ sudo mount /dev/sdb -t ext3 /media/external -o ro
mount: wrong fs type, bad option, bad superblock on /dev/sdb,
missing codepage or helper program, or other error
(could this be the IDE device where you in fact use
ide-scsi so that sr0 or sda or so is needed?)
In some cases useful info is found in syslog - try
dmesg | tail or so

rhg@rhg-laptop:~$ dmesg | tail /dev/sdb
tail: cannot open `/dev/sdb' for reading: Permission denied

rhg@rhg-laptop:~$ dmesg | tail /dev/sdb1
tail: cannot open `/dev/sdb1' for reading: No such file or directory
rhg@rhg-laptop:~$ dmesg | tail /dev/sdb2
tail: cannot open `/dev/sdb2' for reading: No such file or directory

You are correct normally the device gets the /dev/sda or /dev/sdb identifier and the partitions get the /dev/sdb1 2 3 etc so I tried to dmesg the partitions and you can see the results. It appears the superblock is stopping us at the gate.

I sure appreciate you trying to trouble shoot this with me. I have read about dd_rescue but never used it. I'm game to try anything.
randy,
