cd drives dont work on IDE 2 but they do on IDE 1

[lordy]

hi all

ive just finished build my first computer and i must say it all went pritty well. im running window 98 SE at the moment but hoping to upgrade to xp fairly soon.

my problem is

when i put my hdd on to IDE 1 and my cd drive onto IDE 2 my cd drive does not work,

But when i put my hdd on to IDE 2 and my cd drive on IDE 1 it all works apart from my computer is slower for ovious reasons that IDE 1 is faster than IDE 2.

when i plug my cd drives into IDE 2 they are recognised in bios but but then when my computer starts and when i go into my computer on the desktop its not there.

im abit confused so any help would be appreciated

Thanx
Lordy

How do you have your drives jumpered on the back...master, slave, or cable select? IDE 1 is exactly the same as IDE 2, not any faster or slower. It just depends on the type of cable you use. CD/DVD drives are usually ATA/33 so you keep them apart from your hard drives which (the newer ones anyway) are ATA/100 or ATA/133.

Todays HD's are ATA66 and above and work best using the 80 wire cable with the drive set to cable select. Blue connector would go to mobo and black connector for drive you want as master using the grey connector for a slave drive if present.

Optical devices are ATA33 and use the standard 40 wire cable and are designated master/slave by jumpers on drive.

No difference between IDE 1 and 2 for speed.

Check BIOS and see if everything is set up as auto detect.

Some motherboards only have Ultra ATA on the primary, so you can't generalize on both controllers being the same speed. I'd agree that the problem you are having is related to either cabling or jumpering.

Surge - that's not the case, with 80 wire and cable select, a CD slaved to a hard drive will not slow the hard drive down.

Oh ok, thanks for correcting me on that glc!
