The drive came in an OEM version. There is only one button on the front
panel - Load/Eject. There is no even a headphones jack (maybe because the
market is glutted with mainboards with integrated sound). The drive can
read also DVD-RAM discs.

Nero CD-SpeedThe following information on the drive is obtained with the Drive
check utility:
- Vendor : TOSHIBA
- Product : DVD-ROM SD-M1612
- Firmware version : 1004
- Buffer size : 512 KBytes
- Maximum read speed : 8467 KBytes/sec (48 X)
- CDDA accurate : yes
- C2 pointers : yes
- Speed settings : 8 X
- Read RAW mode : yes
According to these data the drive supports all functions necessary for
accurate capture of audio tracks. As we found out later, the speeds defined
by the program are not correct.

DVD-Video playback with the Cyberlink

The DVD-Video was played without any problems; no artifacts were noticed.
During changing the layer the DVD quality didn't get worse.
Noise characteristics
- Tray - 5/10
- CD
- Seek - 6/10
- Total noise - 5/10
- DVD
- Seek - 7/10
- Total noise - 6/10
At the maximum speed the drive makes quite a lot of noise. The reduction
is possible only by means of exterior programs (CDBremse, Nero DriveSpeed).
The speed, thus, can be 48x-32x-20x-8x. The Drive check program showed
only 8x in the list of possible speed settings.
Vibration
When the drive worked with badly balanced CDs it didn't shine. The vibration
was quite noticeable. But it didn't prevent the drive from successful reading
of the disc at a high speed.
Thermal conditions
There are no any complains about its thermal conditions. The data were
read after an intensive 2-hour operation:
T inside the case - 35°C
T of the upper surface - 41°C
T of the lower surface - 42°C
Possibility to make a multizone drive (RPC-1).
According to www.firmware.fr.st,
this drive can be turned into a multizone one.
