    I have the same problem. My laptop crashed and I was not able to save anything, so after reloading XP, I plugged my Beyond Micro Mdl # BMMDU2 back into the laptop as I have backed up everything on it, but it won't recognize the drive. I have no idea what to do next either. I would also appreciate some help on this matter.

    I have the same issue w/ beyond micro external hard drive. I have yet to try this solution, but I have read on another site that the Power Supply is too low at 1.5 watts. Try to use a similar power supply with higher Watts. I have a different brand with higher Watts & the internet solution said that they went to Radio Shack for 1.

The only solution that I have found, due to having same problem, is that original power supply is too low at 1.5 watts. 3 things to try.
1 - purchase another similar external hard drive and use its power supply. (I bought a Maxtor Driive with same plug at 2.0 watts)
2 - purchase power supply from radio shack with higher watts. take drive in with you for tech to match it up.
3 - Remove the Hard Drive from tthe case and connect to a PC as a slave Hard drive.

Any option may or may not work, but worth the try when invaluable data is on your drive.

My WD caviar green keeps blinking and won't show up in any way on my windows pc or macbook pro

Your WD has probably gone belly up. If you can't get it to register on either computer and you've tried different computers then it has croaked.

Were you able to use it in the past on the windows computer and the mac? If so, that's strange because they are two different formats and most times when you plug the drive into one or the other it will want to reformat it to be able to access it.

Assuming this is a USB external HDD...try, if you haven't already, using one of the USB inputs in the back of the computer. When I try mine in the front, it does not work. When I tried the rear, it worked.

2 Switch the laptop off and remove the battery for 30 minutes, replace and try again.
3. Try a different memory stick
