[Bug 953555] [NEW] hdparm fails on usb drives

[Dmole]

Public bug reported:

I used to have a script ask my external drives to spin down less often, but after a recent upgrade the script fails.
hdparm -S 241 /dev/sde;

/dev/sde:
 setting standby to 241 (30 minutes)
 HDIO_DRIVE_CMD(setidle) failed: Invalid exchange
I tried identify but it also faild
HDIO_DRIVE_CMD(identify) failed: Invalid exchange

https://wiki.ubuntu.com/Releases seems to be out of date but the EOL should not be until "April 2015"
nothing in dmesg
