CloneCD Tests
Procedure:
We used CloneCD (v2.7.8.1) and 3 original CDs (Rally Masters, Euro2000
and Incoming) in order to test the reading time for Ricoh MP7120A. We also tested
the reading performance with the backups of the original CDs since the reading
speed varies from original to backup media.
Results:
a) SafeDisc Results: Euro 2000 (Total: 257982 sectors - 10141 bad sectors) - Reading Speed: Max

Verdict
of CloneCD Tests:
The Ricoh MP7120A didn't perform the way that we anticipated. Previous
Ricoh models have had a reputation for very good CloneCD performance. What was
the problem? The drive reported more bad sectors when reading than what actually
existed on the CDs! This was proven by reading the CDs with other readers i.e.
read BUG! For example, the drive continued to report read errors above 10141
sectors in the SafeDisc test until the end of the CD! The Same thing happened
with LaserLock CDs (using both original and backup CDs). We suspect that this
is a firmware error and we hope that a newer version would correct those problems..
Firmware v1.20 didn't seem to solve this problem..
On the other hand drive performed very well with SecuROM protected CDs and was able to read the whole CD in 3:26mins.The PX-W1210A read the same CD in 3:55min. Note: When using the backup CD for reading SecuROM the times goes 2x (5:51mins.).
Overall, the Ricoh MP7120A really needs improve when reading CDs with errors. The drive had real problems correctly reading the original protected CDs.
