I'm busy with other tasks right now.

There are no problems with that, when it is gone from 'info block' all 
traces of the drive are gone and creating another one with the same name 
is not a problem.

For symmetry reasons it would be nice to have a drive_del command though 
and have device_del not implicitly zap the drive.  The current scheme 
also fails to handle some corner cases like device_add failing (you are 
left with a drive you can't remove easily).
