the subst command:



Associates a path with a drive letter.



SUBST [drive1: [drive2:]path]

SUBST drive1: /D



drive1: Specifies a virtual drive to which you want to assign a path.

[drive2:]path Specifies a physical drive and path you want to assign to

a virtual drive.

/D Deletes a substituted (virtual) drive.



Type SUBST with no parameters to display a list of current virtual drives.





So:



subst a: /D



...should remove the substituted drives.



I would ask your friend first, though, why they ran that command. The
subst command is commonly used for networking purposes, or to run a
program that "defaults" to a given drive letter to redirect the program
to using the drive you want it to use. And that's a pretty advanced
command, so I would check with your friend about why that command was
used and what, if anything, would happen if you undid that command....














this is second solution .....

open disk management and right click on the hard disk ...> properties ...>polices...>select enable write caching on the disk then ok... to remove the removal drives
