I recently purchased a SCSI CD-ROM drive off of ebay. It was advertised as the 40x Plextor. However, it was taken out of an IBM server computer, and therefore looked different. When I hooked it up, I noticed that it showed up as IBM CDRM00203 on my computer. Is there some way for me to verify that this drive was manufactured by Plextor? If it is, is there any difference between this and a regular Plextor drive? Thanks.
