Toshiba Introduction
This DVD-ROM drive
is from Toshiba's collaboration with
Samsung and sold under the
Toshiba Samsung
Storage Technologies (TSST) label.
Headquartered in Japan and Korea, TSST (Toshiba Samsung Storage Technologies)
is 51 per cent owned by Toshiba and 49 per cent owned by Samsung. The TSST
joint venture includes product and business planning, product development, procurement
and sales for optical disc drives (ODDs), world-wide.
A little history
about Toshiba's storage
division:
Toshiba Storage
Device Division (former "Disk
Product Division") has been
in existence since 1972 when it began
producing 14 inch Hard Disk Drives
for the OEM market place. In 1975
it started the production of 8 inch
Hard Disk Drives for the then infant
computer industry in Europe, followed
by 5.25 inch, 3.5 inch and 2.5 inch
hard drives. As the industry continued
to grow Toshiba established a European
presence in 1987 based in Neuss,
Germany. Toshiba's presence in Europe
has since expanded to include sales
and support offices in the U. K.& the
Republic of Ireland. Toshiba was
the first manufacturer to offer a
2.5 inch 40 MB HDD using two glass
platters. Nowadays Toshiba reinforces
its industry-leading position with
new high-capacity, high-performance
2.5 inch hard-disk drives up to 80
GB, world leaders in their class.
Toshiba Storage Device Division is
one of the few optical storage vendors
that is able to support its European
customer base directly with local
European Sales, Marketing, Technical
and Operational staff.
Toshiba also developed
the CD-ROM's successor the DVD-ROM
and later the first multifunction
combination CD-Re-writer/DVD-ROM
all-in-one.
Toshiba DVD-ROMs
had a reputation for being of very
high quality and having very
fast error correction abilities whilst
also being able to read protected
/ scratched disks very fast. Consequently
they were the drive of choice for
the popular CD backup program CloneCD.
They are also one of very few
drives that can read DVD-RAM disks
out of their caddy.
The SDM-1912 improves
slightly on the SD-M1802 by having
a larger 512KB buffer.
We have had this
drive for several
months and actually
bought the OEM drive in Akihabara
- Tokyo, Japan on a trip
last year. In this review we will
compare it to the 3 year old Toshiba
SD-M1612 & how it compares against
the read tests of a new DVD writer
a Plextor 716A drive.
What the package includes
The package contains:
Toshiba SD-M1912 DVD-ROM
Drive
In the picture below you can see
that the front has changed from the
normal light brown with square
buttons to a beige square button
front looking device and resembles
a Samsung drive now.
When you install a disc into the
DVD-ROM drive, the BUSY light flashes
slowly as it attempts to locate the
disc. One of the following will occur:
- BUSY light goes out. The DVD-ROM
drive is ready to read data from
the disc.
- BUSY light flashes slowly. The
disc may be dirty.
- BUSY light remains ON. The DVD-ROM
is accessing data.
- BUSY light remains ON indefinitely.
The DVD-ROM is experiencing an
error
The back of the drive looks very
similar to any other ATAPI CD drive.
You will find the usual connectors:
jumpers for making the drive a Master/Slave/Cable
Select, an analogue audio output
connector, a digital & analog audio
output connector and a power connector.
