CD Drives Won't Open

Took my PC to a technician who owns a small computer repair shop for a
simple upgrade.

When I got it back, neither of the two CD drives would open. One's a
read/write and the other is just a read-only. I know they both worked
perfectly when I took them in, because, for one thing, I backed up all
my files and transferred them to a new computer. (I can imagine a
motivation on the shop-owner technician's part for messing with me
intentionally, but of course it's only speculation.)

Anyway, I'm hoping someone might tell me how to fix this?

You push the button, and nothing happens.

You right click on Eject in either of the drives' representation in
Explore or My Computer, and get a message that says the drive is not
accessible.

According to the Properties viewer, they're both reportedly absolutely
full -- to 100 percent capacity with 0 bytes free.

Since locking them shut somehow was deliberately done by a technician,
there must be a way to un-do whatever it was that he did.

I'm praying somebody out there knows and will tell me!

Thanks!

Cory,
Go to the BIOS and see if they (CD's) are being seen
by the BIOS.
If not, go inside the case, and make sure all cables and power cords are
connected.
Hope this helps.
And see what happens.
