$ cat /proc/scsi/scsi

And BTW,

# /sbin/hdparm -M 128 /dev/hda

/dev/hda:
setting acoustic management to 128
acoustic = 0 (128=quiet ... 254=fast)

(failure but I don't care the drive is old and already in AAM mode)

# /sbin/hdparm -M 128 /dev/sda

/dev/sda:
setting acoustic management to 128
HDIO_GET_ACOUSTIC failed: Inappropriate ioctl for device

(This drive however is not and needs it dearly. Plus it's the Linux
drive, so it's used most of the time)
