Dear all,
I was busy with a USb harddrive.
and i did create a partition on it and formatted it.
the commands i used where:
fdisk /dev/sda2
mkfs.ext3 -L backup01 /dev/sda2
I'm 99.9% sure that i have the right disk because:
1 the size of the disk match
2 there where not partitions on it when i started.
but.....
after i have done that the system only gives me this:
-bash: /usr/bin/dir: Input/output error
when i try to connect with vpn to the machine he doesn't answer... what did i wrong?
did i format my main disk ????
I hope someone will help me urgently.... because i do not know what to do! can i restart the machine, did I lost any data?
Kind regards,
ps see a list of the last screen:

Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel. Changes will remain in memory only,
until you decide to write them. After that, of course, the previous
content won't be recoverable.
The number of cylinders for this disk is set to 17737.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)

The partition table has been altered!
Calling ioctl() to re-read partition table.
WARNING: Re-reading the partition table failed with error 22: Invalid argument.
The kernel still uses the old table.
The new table will be used at the next reboot.
