WD My Book 1TB External Hard Drive


A 1 TB external hard drive was added to Belinos (115.11) [081015]. The drive is a Western Digital, My Book, Essential Edition, External Hard Drive (WD10000H1U-0) purchased for AUD $200. The disk was originally formatted as vfat.

After connecting the drive via USB the dmesg command indicated the disk was identified as /dev/sdd1:

A mount made the disk available:



$ sudo mount /dev/sdd1 /mnt
$ df -h .
Filesystem            Size  Used Avail Use% Mounted on
/dev/sdd1             932G  385M  931G   1% /mnt

The current contents (simple documentation and some trial applicaitons) were copied off of the drive to clear the way to reformat it for Linux.

The disk was unmounted, repartitioned, and a ext3 file system was written:

$ sudo umount /mnt
$ sudo mkfs -t ext3 /dev/sdd1
$ sudo mount /dev/sdd1 /mnt
$ df -h .
Filesystem            Size  Used Avail Use% Mounted on
/dev/sdd1             917G  200M  871G   1% /mnt
