ATA66 ??

[wingnut144]

Is there such a thing as a ATA66 CD drive? And if so, who makes one?

Or, how can you tell if a CD drive is ATA66?

Thanks!

If the bios detects the drive as being ATA 4 or PIO 4!

ATA 5 - UltraDMA 100
ATA 4 - UltraDMA 66
ATA 3 - UltraDMA 33

But is there any way on the CD drive itself to see what it supports?

How new would a CD drive have to be to support ATA66?

To my knowledge, there are no ATA66 CD ROMS right now.

Never heard of one yet either.

Asus 8x DVD-Rom at least is ATA 66 capable!

Most controllers will detect what type of drive (PIO mode, etc) is connected to the system, and configures the devices appropriately. For instance, if you hook a CDROM to a UDMA/100 controller, it will see that your cdrom is an ATA/33 device, and use that protocol to communicate with the device. It SHOULD be transparent to you. If you're having problems, try updating your motherboard's BIOS, or your controller's BIOS if available.

ATA/UDMA ratings only apply to hard drives, not to CD- or DVD-ROM drives. You can, however, enable DMA transfers for these drives on the Device Manager/Settings page, but that only allows direct transfer of data to the bus, by-passing the CPU. Strictly speaking, although the drives hook up to the IDE channel and cable, the interface is ATAPI. The drive runs at the same speed whether cabled to ATA-33, -66 or -100 channels.
