View Full Version : [other] So, I just killed my new external hdd

January 30th, 2010, 01:37 AM
Hey everyone,

I just tried installing Ubuntu on my brand new external hdd.
That went terribly wrong, since grub could load neither windows nor ubuntu anymore.

Well, I was able to at least restore my win7 boot by using a rescue disk.

HOWEVER, my external hdd is not recognized by windows anymore. It treats it as an unknown usb device.

I really (really!) need some help here.

probably the external drive has been wiped or formatted to something windows will not read by default (ext4, for example). Try reformatting the drive.

Windows can't read ext3 and ext4 file systems.

Hey guys, thanks for your replies.

After creating this thread, I created a gparted boot cd. I booted from that cd. It also didn't recognize the hdd.

To clarify:

I have a 1TB external hdd. I have ~900gb of that formatted as ntfs. I then ran ubuntu setup and created 2 partitions out of the remaining 100gb. 96 were reserved for "/" and 4gb for swap.

I then installed ubuntu on the / partition.
After that, I couldn't boot my pc anymore. grub just sat there, doing nothing. I then used a win7 recovery cd to restore my mrb. Afterwards, win7 would boot again. However, the external hdd I installed Ubuntu on is not recognized anymore. Not by Win7, not by Ubuntu, not by gparted livecd.

I think something's seriously wrong!

OK, you state that it's "BRAND NEW DRIVE"...
so it should have nothing of value that you want to save (back up)


I do not use Windows 7, but XP had a Drive Management Console that allowed one to manage drives at the physical level.

gparted should have a "drop-down" menu up in the right hand corner,
this is where you choose which PHYSICAL drive you want gparted to use.

see the attached screen-shot.

if this does not work, then it is possible that there are hardware problems.

Thank you, egavlan.

Gparted didn't see the drive.
Fortunately, there was a rather simple solution to the problem:

I unplugged the drive from its power supply.
After doing that, I all of a sudden got full access to the drive again.

Thanks for your help!

Anyways, I asked for advise on installing Ubuntu on an exernal hdd before. People told me to just set up the propper partitions and go ahead.
That went seriously wrong.

When you install on a external drive with a live cd you want to make sure to hit the advanced button on the final install screen and check where grub is going.
