I made a mistake I think. I am trying to create hyper-V on my unit.  I landed up with a basic virtual disk under C.  I am trying to get back my gig's to C and start over.  It seems that everything I find will not cover what I need.

Spec. Disk

Disk: 2

Type: basic

Capacity: 100 G

Unallocated Space: 100 g

Status: Online

Device Type: File Backed Virtual

Partition Styl

If you don't want the virtual hard disk any longer, all you have to do is delete it.  You don't give specifics, so I will have to guess. 

If this is a virtual hard disk used by a VM you tried to create in Hyper-V, first go into Hyper-V and delete the VM.  That just deletes the VM - not the disk.  After deleting the VM, there should be no process using the virtual hard drive, so you just have to delete it.

Another thing you might have done is to create the VHD and mounted it to Windows 8.  In this case, you can't delete it because Windows 8 owns it.  Start computer management (compmgmt.msc).  Go to Disk Managment.  Find the entry for your VHD.  Right-click and detach it.  Then you can delete it.

If it is not one of these things, you are going to have to give a more complete description of your environment and what is preventing you from deleting it.

Hi, Tim.

Sorry for replying to such an old post, but this seems to be the closest to my situations. One of my friends used my computer to download Sims 3, and now I have a virus. It seems to have created a whole virtual CD drive (J:) on my computer, and I can't delete any of it. The drive won't eject or delete. I followed your fantastic instructions here, but it doesn't see (J:). It sees several other drives, just not that one. The virus is on this drive, and Norton isn't seeing it elsewhere, so I can't just delete that either, as it's showing the "disk" as read-only. Do you have any suggestions on how to fix this problem?

Thank you so much!

PS: I have a screenshot if that would help. The forum won't allow me to post it here.
