    Subjecthdparm -Y /dev/hd? lock my harddisk
    Jocking with hdparm I tried `hdparm -Y /dev/hda`, I seen "sending sleep
    command" or something similar. After some seconds with the HD led ON I was
    again on the shell with the HD led OFF, I typed `ls` and the HD locked
    with the HD led ON.

    I can reproduce this lock with any kind of setting in the BIOS (UDMA
    disabled or enabled).

    Kernel is 2.1.105 (I haven' tried other kernel).

    Partition check:
    hda: hda1 hda2 hda3 hda4

    This problem doesn' t harm me at all though, since I never got one problem
    with an IDE disk/cdrom so far and I never need to put my HD to sleep ;-).
    If for the most of people hdparm -Y works, probably is my HD or my IDE
    chipset that make mess with the sleep command...
