Any ideas?

sg_rmsn
SG_RMSN(8) SG3_UTILS SG_RMSN(8)NAME
sg_rmsn - sends a SCSI READ MEDIA SERIAL NUMBER command
SYNOPSIS
sg_rmsn [--help] [--raw] [--readonly] [--verbose] [--version] DEVICE
DESCRIPTION
Send a SCSI READ MEDIA SERIAL NUMBER command to DEVICE and outputs the response.
This command is described in SPC-3 found at www.t10.org . It was originally added to SPC-3 in revision 11 (2003/2/12). It is not an manda-
tory command and the author has not seen any SCSI devices that support it.
OPTIONS
Arguments to long options are mandatory for short options as well.
-h, --help
output the usage message then exit.
-r, --raw
sends the serial number (if found) to stdout. This output may contain non-printable characters (e.g. the serial number is padded
with NULLs at the end so its length is a multiple of 4). The default action is to print the serial number out in ASCII-HEX with
ASCII characters to the right. All error messages are sent to stderr.
-R, --readonly
opens the DEVICE read-only rather than read-write which is the default. The Linux sg driver needs read-write access for the SCSI
READ MEDIA SERIAL NUMBER command but other access methods may require read-only access.
-v, --verbose
increase the level of verbosity, (i.e. debug output).
-V, --version
print the version string and then exit.
NOTES
Device identification information is also found in a standard INQUIRY response and its VPD pages (see sg_vpd). The relevant VPD pages are
the "device identification page" (VPD page 0x83) and the "unit serial number" page (VPD page 0x80).
The MMC-4 command set for CD/DVD/HD-DVD/BD drives has a "media serial number" feature (0x109) [and a "logical unit serial number" feature].
These can be viewed with sg_get_config.
EXIT STATUS
The exit status of sg_rmsn is 0 when it is successful. Otherwise see the sg3_utils(8) man page.
