bad mbr on usb 2.0 hard drive

I have a problem with my usb extrenal drive;

After a recent formatl I re installed my 250 gig WD external HD; windows device manager sees it there, but I cannot access the files through explorer or any other way..I think I mayhave messed up the MBR..
There is critical data on that drive, and I need to recover it..How can I do this?

thanks so much!

Well, what happened was that somehow, while formatting the pc, the attached usb hard drives had their MBR's corrupted; now, even though windows deveice manager shows they exist, I  cannot access any files on them, either in explorer or any other way...I need the files very badly, so somehow, I have to repair the MBR's without formatting or deleteing any files off these external, USB drives...

Any suggestions would be greatly appriciated!


thanks again

Efficient way to get backups off site to Azure

This user guide provides instructions on how to deploy and configure both a StoneFly Scale Out NAS Enterprise Cloud Drive virtual machine and Veeam Cloud Connect in the Microsoft Azure Cloud.

 
ChipM0nk JGLeaderCommented:
The tools above should do the trick.  If you have problems accessing the disk, due to the USB interface, I would suggest removing the disk from it's case and installing it as a normal internal EIDE/ATA drive so that you can access the disk using the native controller.  Then the tools above should do the trick then.  Personally I've used File Rescue http://www.file-rescue.com/ and found it to work well.  

Of course, you will need another disk in the system to copy the data to and then I would suggest that you burn it from there to CD-RW.  

Then you can put your disk back in the USB case, repartition, format it and copy your data from the CD-RW backup - that you might want to keep up to date so this doesn't happen again.

Well, I got the data back, thanks to the tools above..Now, I need to make the USB drives useable again, which will mean formatting them...
There MUST be a way to do it, without removing the drives from the cases and installing them in a "regular" pc...They show up in Device Manager, but NOT in Explorer or My Computer..

Any ideas ??
thanks so much!

No, I cannot see it on another pc...either the MBR is messed up,. or something...
I was able to recover the data,.but any pc I plug it into will show it in the Device Manager, but NOT in Windows Explorer or MY Computer...

I just want to some how format it to its clean, NTFS state, then I can use it again..But its impossible to format it unless you can "see it" in Explorer or My Computer..

thanks!
