It did work!!!
Now you must unmount it
with the -f option,
and run fdisk or parted or gparted to partition it
as you see fit.
Then you must mkfs the specific partition you want to mount
as read/write.
After mkfs finishes, you can mount it.
.
[root@box10 /]# dd if=/dev/zero of=/dev/sdh bs=4M
dd: error writing ‘/dev/sdh’: No space left on device
932+0 records in
931+0 records out
3906453504 bytes (3.9 GB) copied, 4.52491 s, 863 MB/s
[root@box10 /]# umount -f /dev/sdh
umount: /dev/sdh: not mounted
It is not mounted, all I can mount is the 3.9GB partition.
I really believe this thing has failed.
