Hi Technical Information,
You can move the database to a different HDD and expand the drive space and move it back.
There will be downtime when you move database to a different drive or disk.

Or if you dont want downtime you can create a new database and move the mailboxes to the newly created database and and delete the old database and resize the drive/disk and move the mailboxes to the database in the expanded drive.

Make sure your backup is successful before hand.
Is this a VM or are you physically replacing a drive? If it's a VM then it's a straight-forward disk expansion. Expand the VHD; then in windows Disk Management you should see the additional hard drive space. Right-click on the volume and select 'Expand'. Just have a backup of your data first  ;-)
it 's ok Expanding same driver ..
1- take backup , dismount database edb.
2-expand your driver with same driver letter ,don't change the name or path ..

expanding with new driver
1- take backup , dismount database ebd.
2- add your new driver.
3- change driver letter as old drive .
4-recover your db to the same path .

do it in test inviroment before so you will see all proccess in safe way .
