I have an external usb drive that I'm setting up as a backup hd. I've partitioned and formatted the drive as ext3. I can mount the drive manually at the prompt, but I can't seem to get fstab to mount it automatically on boot. I've changed the /etc/fstab options several times without much success. Here is my most recent setting:

   /dev/sdb1   /backuppc   ext3   rw   0   0

Change "rw" to "rw,auto".

Since this is a USB drive, and it might not be sdb at some point
in the future, you should think about using udev.  Then make a site-
specific device name that the system will always map to that drive,
no matter where (sd[a-h]) the kernel decides to assign the drive.

I read up on udev at http://www.reactivated.net/udevrules.php. Using the examples, I was able to create a /dev/usbhd_sg for my specific external hd. However, I'm still unable to mount the drive automatically at boot. I can still only mount manually. I changed the /etc/fstab option to "rw,auto".

I haven't found anything new in dmesg on the external drive, but I did come across the following for my internal SATA hard drive:

The internal drives seems to be recognized as a USB Mass Storage device as well, and the partitions on that drive are being mounted properly as ext3. Any suggestions as to why the external USB drive is not doing the same?

Thanks,

Hannuman
