So after my computer was accidentally powered down, I booted up to find D: Drive(CD-Rom Drive) missing from the listing on My Computer. After scouting around a bit, I found it was missing from the Device Manager listing, and there was a message upon bootup stating that Drive 4 (CD-Rom drive) was not found.

 

The Drive itself is working, it opens and closes and flashes it's lights but it just is not being recognised by the computer.

 

I have checked the cables inside, and everything seems fine.

 

I have done something with registry entries as suggested on an internet help site, and followed other instructions but nothing seems to work.

 

tl;dr-Computer powered down at mains by accident, drive disappears but still connected and appears to still be in full working order.

 

 

 

Halp!

Something might have gotten messed up in your CMOS just go into BIOS and renable it.

Care to elaborate in terms for the less computer-literate? :P

When you boot your system, press either F2 or delete to open your BIOS menu.

 

From there you want to select your secondary slave* (im guessing its this since you say drive 4) and set it to automatic, Check that it is recognised. If not try unplugging it and booting up normally then shut down and reconnect and see if it appears.

 

 

 

These problems are annoying as there sometimes isnt any clear reason for it to dissapear from the list. Also make sure the cable(the big wide flat one) is in the correct way and is in securely (The red stripe should be closest to the power cables on the back of your CD drive.)

 

 

 

*Depending how many drives (Hard disk and CD drives) you have it may be primary slave(1 hard disk and 1 cd drive), secondary master(2 hard disk or 2 cd drives), secondary slave(2 hard disks and 2 cd drives).

Might not be a big flat wire could also be a sata cord to which is small.

Good point, but isnt many Sata CD drives around. I think. Also sata can only go in 1 way really. Unless you use a mallet :lol:

Serious man? Sata is the most common thing now a days. Also what is the only 1 way?

Well its like USB, you cant put it in upside down unless you force it. Im not super clued up with Sata, but from what i remember its not possible to plug it in wrong unless you use force.
