ok so i bought a usb enclosure for my drive but still when i connect it to my pc it recognises that i have connected it, but still wont show anything up , hmmm im stumped

Just to be sure:

When you click Start > Run and type in diskmgmt.msc and then click OK

Is the USB enclosed drive listed? What does it say?

Sounds like it may need to be formatting / the file system was corrupted.

You could try recovering using these softwares (don't format the drive til you've tried recovering the files):

Recuva - Download

PC Inspector

If none of those works then try formatting the drive by right clicking it in Disk Management and choosing Format. Note though that formatting will mean any data on the drive will be lost forever (unless you have a few hundred quid to spend on "professional" file recovery). But formatting should make the drive useable again.

the drive doesnt even show up to allow me to format it, it just bleeps to let me know the usb device is connected but isnt listed anywhere on my pc

What size hard drive do you have?

I think drives over 120GB or so require an exernal DC power connection.

Does your USB enclosure have an external power source or is it just USB powered? That could be the issue.

its externally powerd it doesnt get its power from teh usb , it switches on started to spin then just clicks constantly then my computer makes teh bleeps but doesnt find it or locate it , i tried putting it in the freezer fora few hours but i retrned and it still does the same damn thing

The clicking is bad. It means its having trouble seeking / finding data on the hard drive.

How long did you leave it in the freezer for? Try leaving it in for 24 hours (wrapped in a zip lock bag or plastic bag).

If the files are important then all I can recommend is Active File Recovery. Connect the hard drive then run the software. I used it to recover files off a hard drive which was clicking and not working just like yours.
