Hi Adityar,

It shows all partitions on your SSD and HDD, you don't want to delete 'RECOVERY' or '\\?\Volume{...', the second is the partition that makes your system bootable.

Are you have a ? Volume in disk defrag?

Hey Adityar,
I had a couple \?\Volume in disk defrag and I found that it was due to not having a Label on the given partition(s). Mine turned out to be my EFI System and Recovery partitions and I had to use MiniTool Partition Wizard (Free) to give each of them a Label, so I would know what they were.

It's my EFI partition.

You never need to defrag static hidden drives.

As mentioned above. If a partition does not have a mount point or no label. The volume GUID is displayed instead. To mount the EFI System partiton, open Admin Command Prompt and type:

mountvol U:\ /S ==> this will assign a drive letter U: to the EFI partition.
label U: XXX ===> Will label the partition with the string "XXX"

The screen now shows:

To revert back:

label U: ===> hit <ENTER>->Y to Remove the label
mountvol U:\ /D ===> unmount drive U: from EFI partition

NOTE: Use the command mountvol with no argument will list all the mount points and drive letters
