My Passport 250GB Not Detected in My Computer

Model #WDBAAB3200ACH-00

I have a My Passport 250GB that is not detected in My Computer, and Disk Management. I plug it in, the light turns on. You can hear it spinning normally, and there’s no clicking to make it sound like it’s physically damaged. I downloaded WD Firmware Updater and Quick Formatter, neither of them can detect it either. I have been struggling with this problem for a long time, and have a lot of valuable info on there. I am willing to cut my losses and format, but I can’t even get a detect to access and format it. I have barely used it, and it has mostly been collecting dust on my shelf. I use it as storage for all of my music that I am producing. 

I tried using vista 32 bit and XP, neither can detect the drive.

It used to be accessed just fine.

I appreciate any help I can get.

Thanks…

Did you try a different cable? They also make a power booster cable contact customer service.
