SCSI QUESTIONS!!!

[rthebest]

I had a question, I was thinking of buying the Yamaha CRW4260TXPM (http://www.yamaha.com/cgi-win/webcgi.exe/DsplyModel/?gHDR00007CRW4260TXPM).

It is an external cdrw drive that requires a SCSI card, but it doesn't specifiy which type. Will I be able to use a 50pin regular SCSI card, or do I have to have a 68 pinn UW Card?

And currently I have a Promise ATA/66 PCI controller. Will the two controllers be able to work on the same system together?

Any help would be greatly appreciated, thanks.

Hi

The spec say that it is a U2W. So. it has a 68 pins SCSI connector at the back.
U2W is backward compatible, so you can use it with older SCSI adapter, as long as you have the right cable !

Unless you take the drive out of it's case and use it internally, you do not need a 68pin UW cable. You will need an external cable, but the ends will vary depending on your SCSI adapters external connector. The unit, I think, has a standard SCSI2 external connector on it ( At least the external 4416SX I used did ).

I almost forgot to say...I use a U2W SCSI card for my Internal 6416S drive, and I also use a FastTrack Raid-0 drive array. It seems the Promise takes over all SCSI booting...as I can not even boot to a SCSI drive with teh Promise installed, so You should have no problems.

What exactly does U2W and the 68pin connector get you? Would this work just as well with the 50pin (SCSI2?) connector?

It gets your external SCSI device connected to your machine so that you can use it. http://www.sysopt.com/forum/smile.gif

I work with SCSI all the time but this is no place to hold a training class. www.scsita.org (http://www.scsita.org) is a very good site that probably already has all the answers to your questions.
SCSI is definetly better than ATA/DMA and that is why it costs more. But then again, EEC RAM is better than vanilla memory chips but most people will not pay the extra for a PC.
