Second internal drive not showing up

I have two internal drives the C drive as my system drive and another I named M (for music) which is basically a backup drive. A year ago when I installed Windows 7 Home Premium is also the time I set up the M drive (both drives are about a year old).

I haven't had a bit of trouble until I just noticed my M drive was not showing up anywhere not in "Computer", "Device Manager" or "Disk Management". Now if I run Belarc Adviser it does list both my C and M drive.

I opened the case to make sure the M drive was running and it was with no noticeable noise in fact it's pretty quiet so I don't think it's a hard drive problem.

What do you think has happened and what do I need to do to get Windows to recognize it? Thanks!

1)Shut down, remove the cables, reboot, shut down, replace cables, restart. ( from M: drive )

Post back.

Also try going into your Bios, or check the POST screen to see if the M drive is detected. Also go into device manager/disk management and see if the drive letter is assigned.

Theog that did the trick hopefully this doesn't become a recurring thing!

Whoa the next day the drive disappeared again what's going on here do you think maybe something is wrong with the drive after all?

It would be worth check out all your hardware, cable, PSU, HD etc. Good luck.
