The ATA Identify or SCSI Inquiry are safe commands to test. My computer
has a SATA drive at /dev/sda. My results:

# hdparm -i /dev/sda

/dev/sda:
HDIO_GET_IDENTITY failed: Inappropriate ioctl for device

# sdparm --inquiry /dev/sda
    /dev/sda: ATA       Hitachi HTS54168  SB2O
Device identification VPD page:
  Addressed logical unit:

Does that help?
