Subject: [Lugstuff] 4TB external drive
Message-ID: <20100404160504.GA3484@ad.usno.navy.mil>


Dear Linux user group,

I recently got a Western Digital 4TB Book external drive and have a
problem formatting it.  Plugging into a Mac it shows 4 trillion available
bytes and by a click with the mouse it formats the 3.6 TB (2 internal drives)
as a single partition.  That, of course is not readable by Linux.

Running RHEL, after plugging into the USB port the  dmesg  shows a
"very big device" but can't determine properly its size.  I was told
to put a GPT system on.  fdisk is not supposed to work while parted
should.  With parted I can make a GPT lable, but my computer "sees"
only about 2 TB max, I can't even create a 3TB partition.

Here is the extract from dmesg:

input: Western Digital My Book as /class/input/input17
input: USB HID v1.11 Device [Western Digital My Book] on usb-0000:00:0a.1-7
 Vendor: WD        Model: My Book           Rev: 1015

scsi 19:0:0:1: Attached scsi generic sg6 type 13

Any suggestions?  Is there a newer version for "READ CAPACITY" ?
How can I make my computer detect the correct physical size of
that drive.  Having 2 internal drives instead of 1 does not seem
to be an issue.  I can easily format a Western Digital Book 2TB
which has 2 x 1TB internally.  Even fdisk can make a 2TB partition
on such a unit.
