Format and mount problem - External USB harddisk
I recently decided to format my external usb harddisk, so I can write to it using linux. The drive was NTFS before.
I started qtparted and formated the drive with the ext3 filesystem. After a while qtparted gave the following error:
There was a problem with mkfs.ext3
I tried to mount the drive with:
mount /dev/sda1 /mnt/usb
This works, but when I try to write something to the drive I get a message saying the filesystem is readonly. After that the LED which is on the USB-case stays amber. After the write attemt I'm unable to unmount the drive, umount gives the message "device is busy".
When I turn the drive OFF and ON the LED stays amber.
