Can you put CDROMs on Promise controllers?

I have an onboard Promise 20276 ATA133/RAID controller on my mobo. Is this only for HDDs or can I put my DVD-ROM on it?

I have an add on PCI promise controller. When I put cdroms on it, I have problems. Even with a zip drive on it it still messes up. I would suggest you try it first and see.

No problems at all. It should work with any ATA devices. I have a Promise HDD controller (non-RAID, though: Ultra133 TX2) and I've got a DVD-RW and a HDD connected to it. Before I bought that DVD-RW, there was a DVD-ROM instead. :p

Shouldn't hurt to try. :)

This controller does not read / initialise all ATA 33 hardware correctly, although is usually OK on ATA 100 etc hard drives........ depends on the make, as other people have said.
You pay your money and you take your chance.

I tried and it worked. Thanks for all the advice. It may have worked because the DVD is a UDMA mode 4 (66) device.

I never knew CD/DVD drives could go up to UDMA4. o_O So far all of my CD and DVD drives have a maximum of UDMA2 on the controller. *_*

What's up with that? I'd really like to know if my DVD-RW supports UDMA4, which should improve burning/reading greatly.

my 16x pioneer dvdrom is udma 4, but only some dvdroms are. i haven't seen any cdroms or cdrw's that were anything but udma 2. dvdrw's, on the other hand... i imagine some would be udma 2 and some 4, just like dvdroms since they're max throughput isn't going to be any higher (16x is the fastest right now, right?). udma 2 can handle burning dvd's at 4x or even 8x just fine.

Ep, glad to see you come back and tidy up...did want to ask a one day favor, I want to enhance my resume , was hoping you could make me administrator for a day, if so, take me right off since I won't be here to do anything, and don't know the slightest about the board, but it would be nice putting "served administrator osnn", if can do, THANKS
