CD-RW Roundup Vol 2 - Page
- CyberDrive CW-058D
drive supports 32x writing (Z-CLV), 12x re-writing, 2MB Buffer and "ExacLink"
as the main buffer underrun technology. The maximum reading speed of the drive
is 48x (CAV). The exact writing speeds are 4x, 8x, 12, 16x, (CLV), 20x, 24x,
28x and 32x (Z-CLV). The re-writing speeds are 4x, 8x and 12x. The drive doesn't
support Mt. Rainier format, which should be added in newer models. According
to CyberDrive's press release "The drive supports all RAW formats including
EFM correction", which however didn't confirmed from our test results...
The drive utilises a quality media detection system, which automatically lowers
the maximum recording speed, according to the inserted media condition. The
drive will reduce maximum writing speed down to 28x, 24x or even 16x in case
it detects low quality of media.
- CyberDrive's 32x writing speed
The CyberDrive supports 32x writing speed with the use of the Z-CLV writing
technology. Below it's the Nero CD Speed writing graph that illustrates the
use of Zone-CLV writing technology:
The 32x writing speed range is divided in 5 zones: The drive starts writing
at 16x from the lead-in area till 8mins, shifts up to 20x at 10mins, up to 24x
at 24mins, to 28x at 36mins and lastly shifts to 32x at 52mins and stays there
until the end. The average recording speed is 26.41X, as Nero CD Speed
shows, making it faster than AOpen CRW3248 but slower than Philips PCRW3210.
It's quite interesting how the drive passes from 16x to 20x since it almost
doesn't lower its recording speed like other recorders do. This happens again
at 20x -> 24x speed, where the drive doesn't lower at all the recording speed!
That gives the drive an advantage, which affects the final recording speed.
The drive instantly lowers the recording speed for shifting from 24x to 28x
and from 28x to 32x.
- The package
package supplied was the retail European version. This included: the drive itself,
an installation guide, audio cable, a CD-R pen, 1 piece of CyberDrive 80min
32x CD-R blank (actual manufacturer Ritek), 1 piece of CyberDrive 74min HS-RW
(actual manufacturer Plasmon) and mounting screws. The software supplied with
the drive was Nero v220.127.116.11 and InCD v3.12. We don't know if the drive has a
2-year warranty (only in Europe). The complete package will be available at
€129 including 16% VAT. (s.r.p.).
The front of the drive doesn't have the CyberDrive logo, and just gives the
features of the drive "32x/12x/48x" - no HS-RW logo is present. You
will also find only one led, the eject/stop/play/next buttons and the headphone
input jack/volume selector:
At the back of the drive we will find the usual connectors (IDE interface,
power), the jumpers for setting the drive as a Master/Slave, the SPDIF output
connector and the analog/digital output connectors:
CyberDrive CW058D was installed as Master in the secondary IDE Bus. The drive
worked in UDMA33 mode and under WinXP, DMA was activated automatically.
The drive was a January 2002 model with firmware revision v0.72 installed.
CyberDrive supplied two new firmware revisions (0.96D/0.98D) that fixed some
of our initial problems. The latest version used for all recording/reading tests.
We used Nero (18.104.22.168), InCD (3.21) and CloneCD (22.214.171.124) for the recording
