Help with CD and DVD drives with new case

I recently purchased a new case and power supply and took them with my computer to a computer service shop to have everything removed from my old case and put into the new case. Everything was working fine, just wanted to upgrade the power supply and have better cooling with a new case. Anyway, the place (who I trust) calls and says everything transfered fine, but the cd and dvd drives will power up, but they will not read any discs. It worked fine just prior to the transfer. They then put the old power supply in the new case and tried one in their shop with the same result. Any suggestions on what I can tell them might be the cause of the problem? The new case is an Aerocool and the power supply is 550 watts, also by Aerocool. Asus motherboard, 3.2 P4, Windows XP w/ service pack 2 and all updates loaded, the dvd burner is a Sony, but I am not sure of the cd. Any help would be greatly appreciated.

Take it to another shop. It doesn't matter how honest this shop is if they can't figure out something so easy.

The problem is that there are lots of easy things that can cause this problem:

1.) Your motherboard came with new IDE cables, they should use those.
2.) Not all boards work with all devices in "Cable Select" mode, you should have the drives set as master and slave.
3.) The CD and DVD drive should not be sharing the same cable as the hard drive. Especially if it's a Western Digital hard drive, because most people are too lazy to figure out the proper way to jumper WD drives.
4.) Master at the end of the cable, slave in the middle of the cable.
5.) Auto setting for the optical drives isn't always needed, most newer boards will find the drives even if drive type is set to "none".

I spoke with the shop this morning and they have already done all of the suggestions that are listed above. It may be that the CD burner is bad and they are just not waiting long enough for the DVD to spin up. Hopefully that is all it is. Any other suggestions?
