I have a problem with my external hard drive.

I always plug it in with the usb when my pc is running and it always loads up as my j drive and i just open it up.
Earliar today though,i accidently plugged it into the usb before i started my pc up and just before it loaded up windows,loads of file came up across the screen,like it was disk scanning them.After a few minutes it stopped but when it loaded up windows when i click on my computor the operating system c drive comes up and it says 450 gb of 586gb,but wheres my 1 tb hard drive used to say about 680m gb of 990gb,it says nothing now,just the j drive with the external drive pic.when i try to click on this it just says j drive is not accesible,access is denied.

What have i done,i have got loads of music,pics and videos on this drive and i really hope i have not lost them for good.

Please can someone help

Have you unplugged your drive, taken the power off it and reconnected?

  tomcat007 17:08 14 Sep 2009

yeah,tried that mate

And a re-boot of the PC?

Do a system restore on vista back to before the problem started and retry.

Idea is to get rid of the drive information in the registry.

Maybe click here this is for XP though, some thing to do with admin permissions.
