AFAIR hdparm doesn't work on usb drives, as they use the SCSI transport |
| 16 |
with a SCSI to ATA translation on a protocol bridge chip in the usb |
| 17 |
enclosure. |

|

You would think to use sdparm then, but the translation is apparently |
| 20 |
minimal, so unfortunately you can't do things like spin down, etc. |

I would guess you could unload the usb modules (uhci, ehci) but then you |
| 23 |
would loose all usb... |

If voting could change the system, it would be illegal. If not voting |
