[Cialug] USB mounted drives

There is a sleep/auto spin down feature on the USB hard drives which
doesn't get disabled automatically on certain or older Linux versions.

 

Look at the hdparam command or search the net for "hdparam sleep usb
drive".

 

Once the drive sleeps, you must umount/fsck/mount it again to force it
back awake.

 

Also the hdparam is not sticky.   It has to be set every time the usb
drive is inserted unless you have a script run the command upon USB
insertion.
