I wonder if someone can help me, I have a laptop hard drive installed in a case, making it a portable hard drive but for some reason Explorer does not recognise it but when I go into disc management it shows it on the interface.
branflan is correct. if the HD was a bootable windows install at one point in its life you will need to go to the diskmanager and right click on it and click "online". As soon as you click on line windows should give it a drive letter so you can see it in my computer, and browse all the old files.
If you dont need the old files at this point you can reformat it or even delete and recreate the partition.
Thanks for the suggestions but all I get not greyed out on a right click in Disk Management is "delete" or "help". There are two partitioned volumes showing, one says:- healthy (active primary partition) and the other says heal
healthy (primary partition) on the right side box it names it as Disc 5 basic 298.09 GB Online but it doesn't show up when I open "My computer"
