Mounting split raid drive as normal drive via USB


I wish to take one drive from a raid 1 array and mount it on another machine via USB and copy data from it.

Plugging the drive in gets it detected as a scsi drive.

Code:
Disk /dev/sda: 300.0 GB, 300069052416 bytes
255 heads, 63 sectors/track, 36481 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *           1          13      104391   fd  Linux raid autodetect
/dev/sda2              14       36481   292929210   fd  Linux raid autodetect
Mounting /dev/sda1 works fine but /dev/sda2 gives errors.
Code:
[root@c3 /]# mount -t ext3 /dev/sda2 /hd
mount: wrong fs type, bad option, bad superblock on /dev/sda2,
       or too many mounted file systems
[root@c3 /]#
Am I doing something wrong?

raid 1 is mirroring so you will therefore not be able to access the second disk and only the first one. why do you need to mount the second disk in the array anyway? is there any reason you can't use the first one seeing as it should have the same data on it as the second one.

Hmm.. I thought the two drives were identical as opposed to raid 0 where they are striped.

Anyway, makes no difference which drive from the array I try to mount on the second machine, the second partition is unavailable.
