I purchased the Yamaha CRW2200 CD-RW quite some time ago now, and have been successfully using it without the SCSI converter (ie. in EIDE mode) without any issues.
I've decided to use it in SCSI mode, to overcome the issue of potential buffer underruns when copying directly from an IDE CD-ROM drive (which used to be on the same IDE channel).
I've tried with a Tekram 315U, a Kowell KW-910U (Initio chipset) and an Adaptec 39160. I've tried with different "known-good" 50-pin SCSI cables.
I have the CRW2200 configured exactly as the Yamaha manual specifies (SCSI ID3, Parity ON, Termination ON, Block OFF on the SCSI converter).
The symptoms are as follows:
* the SCSI card is correctly detected by WinXP Pro (with latest manufacturer firmware and/or drivers as appropriate)
* the CRW2200S is detected by the operating system, and the drive appears in Windows Explorer as a "CD-RW Drive".
* when any CD media is inserted, the drive spins up, attempts to read, and ends up in a loop of retrying and failing (if you try to click on the drive or access it in any fashion while a disk is in the drive, the program stops responding until you remove the CD media)
For reference, the system contains the following:
* Tyan TigerMP motherboard
* 2 x AthlonMP 1800+ CPUs
* 1GB of ECC Registered DDR SDRAM (2 x 512MB Samsung DIMMs)
* 128MB ATI Radeon 9700 Pro AGP graphics card
* WD800JB Western Digital 80GB ATA HDD (IDE0 Master)
* WD400BB Western Digital 40GB ATA HDD (IDE0 Slave)
* Pioneer DVD-116 16x DVD-ROM (IDE1 Master)
* Adaptec 39160
* Yamaha CRW2200SZ (SCSI channel A, SCSI ID3)
* Intel PRO/100S Management Adapter (NIC)
* 3.5" 1.44MB Sony FDD
* Leadtek WinFast TV XP (TV tuner)
* Creative Labs Audigy DE (soundcard)
* Enermax 550W PSU
I have installed the Adaptec U160 SP4.
ps. I know the 39160 is overkill: I will soon be adding 1 or 2 15K.3 HDD(s)
