I have a 18 GB hard drive in a case with a power supply and a

at /dev/sde1 and I was able with fdisk to put 2 partitions on it that
are called /dev/sde1p1 and /dev/sde1p2. Here is what fdisk shows:


The device mounted as "/dev/sde1" should be one partition of the
disk "/dev/sde".


root@karl-desktop:~# fdisk /dev/sde1


It should be "fdisk /dev/sde" instead.


Device Boot Start End Blocks Id System
/dev/sde1p1 1 25000 12599968+ 83 Linux
/dev/sde1p2 25001 59597 17436888 83 Linux


Now that's strange - there should not be partitions within partitions.

Probably fdisk thinks, the data from the first sector of that
partition
must be a partition table (which is wrong).


root@karl-desktop:~# mkfs.ext3 /dev/sde1p1
mke2fs 1.40.2 (12-Jul-2007)
Could not stat /dev/sde1p1 --- No such file or directory


Glad it didn't work - I suppose that was close to a disaster.


It must be a problem with the USB connection. I was frankly
surprised and happy that the fdisk worked properly, or appeared to at
least. Does anyone have experience that might help?


No, the USB connection is OK. Just use the correct name for the
devices
you want to use, i.e. /dev/sde for the fdisk command. And before you
format a partition, umount it, if it is mounted.

Thanks Nils, I plugged the thing back in, used fdisk /dev/sde and it
came right up. I removed the existing one and made a new /dev/sde1 of 30

GB and saved it. Then I unmounted the thing and used mkfs.ext3 /dev/sde1

and it did that exactly right.

The next thing is to put this Ubuntu on it with all the stuff attached
for a good backup using dd. Then if the worst happens I can dd it back.

Or rsynch perhaps.
