delete drive letter is no longer available in windows 7

I deleteed a the X drive in HKEY_CURRENT_USER>Software>Microsoft>Windows>

CurrentVersion>Explorer>MountPoints2

However when I try to remap the X drive it is not available.  I cannot find it in disk management, and net use says it is not available when I do a  net use X: /delete and when I do a net use X: SHARENAME it says it is busy.  How can I recreate the X drive?

Can you restore your Windows 7 system to a prior point to recover the registry?

Also try running System File Checker but I do not think that applies here.

Open an admin command prompt and run SFC /SCANNOW. Allow to complete, restart and test.

system restore is disabled and I do not think a sfc /scannow will fix this issue, but I will try it tonight

If you cannot run System Restore and if SFC fails as well, you may need to try a Windows 7 Repair Install. Here is a Seven Forums tutorial on how to do that.

Nope does not work, the X drive still is not able to be added.  I was able to se ethe X drive doing what Andrew Koffron said, however it did not look right.  The files were not good int here and it had a big red X on it saying CDFS underneath it

You may need to do the Windows Repair Install
nobus

>>  CDFS   <<  this means the dive does not have the NTFS file system
this can be caused by a a bad drive
i suggest to run a quick diag on it to ensure the drive operates OK (i always use the ubcd for this)
Hardware diagnostic CD    UBCD

go to the download page, scroll down to the mirror section, and  click on a mirror to start the download
Download the UBCD and make the cd   <<==on a WORKING PC, and boot the problem PC from it
Here 2 links, one to the general site, and a direct link to the download

since the downloaded file is an ISO file, eg ubcd527.iso - so you need to use an ISO burning tool
if you don't have that software, install cdburnerXP : http://cdburnerxp.se/

If you want also the Ram tested - run memtest86+ at least 1 full pass,  - you should have NO errors!
 
For disk Diagnostics run the disk diag for your disk brand (eg seagate diag for seagate drive)  from the HDD section -  long or advanced diag !  (runs at least for30 minutes)

if this is ok, you can run HDDRegenerator trial on it : http://www.dposoft.net/hdd.htmland check if it finds bad sectors

@nobus it's a mapped drive,  format is dictated by the machine holding the Share.

@mmercaldi use the net command to delete the drive and then map X: to a share on the same computer like "net use X: \\127.0.0.1\share" see what it show, delete and put back correct share.

found out it was actually used as a hidden dvd drive.  But I will give points to Andrew Koffron becuase his would have worked if it was actually missing
