I am trying to get our linux machines to recognize a new Western Digital My Book 1TB external drive. We are running the CentOS 4.4 distribution on Dell PCs. From what I can tell, the enclosure houses two separate 500GB drives. The drive is formatted as an NTFS RAID0 disk. When we plug it in via USB, I see the following when running 'dmesg'
scsi7 : SCSI emulation for USB Mass Storage devices
Vendor: WD Model: My Book Device Rev: 104a
Type: Enclosure ANSI SCSI revision: 02
Attached scsi generic sg1 at scsi7, channel 0, id 0, lun 0, type 13
USB Mass Storage device found at 12
input: USB HID v1.11 Device [Western Digital My Book] on usb-0000:00:1f.2-1
So it looks like the machine sees the drive at /dev/sg1... but the problem is that the SCSI system is not mapping sg1 to sda, sdb, etc. Therefore, if I try to do an 'fdisk /dev/sd*' it just says that it cannot open the disk.
I found this site: http://linu.gs/misc/remember/wd-mybook-1TB-on-linux.php
--- but it didn't help my problems any. We tried reformatting as RAID1 and still couldn't get the linux machine to map the device so we could reformat as ext3.
Any ideas? Anyone else have similar problems? Anyone else think this could be a RAID problem? I have never before had any problems with WD My Book external drives formatted as NTFS. I can always see them in fdisk and reformat them for ext3... not so with this drive.
BTW... I purhased a Fantom Drives external 1TB drive and it is awesome! Works like a charm and is pretty quiet, too. For what it's worth... I do not like WD products.
