Thread: Ata to Usb Interface

  1. #1

    Default Ata to Usb Interface

    Dear all I have a 500Gb Ata hard disk which I connect to my system with the ata to usb cable.
    I formatted it as ext4 using Yast and I would like to use it for storing backups.

    The only problem I have is that I do not know after I plugged in my hard disk and completed what I had to do how I should shut it down .

    I am not talking about unmounting I am discussing how to shut down the hard disk before I remove the power cable. There must be a way to tell to the hard disk to park the disk heads and shut down.

    Do you know how I can do that in Linux?

    Regards
    Alex

    Hi,

    I have personaly a WD USB external and all I have to do is unplug the USB cable and the electrical plug, that's all. The disk park the heads when the USB cable is unplugged.

    Same here. I have an external enclosure with a HD in it, and all i do is unmount it (eject). then you can turn it off. The important thing is to unmount it.

    You don't have to worry about heads parking. I haven't since XT time. But you should unmount the filesystem.

    No strange at all, it is the same with internal HDs. When they are powered
    off, a spring parks the heads automatically. Only the original HD used in
    PCs, pre 1980, needed parking, because they used step motors for the head
    movement.
