I need to OPTIMIZE/DEFRAGMENT an USB attached via an USB3 In Windows 10.
When the USB drive is selected, TOOLS is open, and CHECK or OPTIMIZE is pressed, the list to perform either, only the INTERNAL [root, SYS_DRV, WINRE_DR] are shown.
Anyone? Best way to OPTIMIZE/DEFRAGMENT a USB Drive?
It would be appropriate to ask 'why'? What benefit do you think there will be? With a large drive, likely to take a long time.
That said, see e.g.
Should I Defrag My External Drive, and If So, How? - Ask Leo!
If something fails to work, please post a screenshot.

Press the Windows key+S in the search box type Optimize. Select Defragment and Optimize drives. Select the drive you want and press the Optimize button.
On an SSD drive, this only has to be done once in it's lifetime
why?
1. This USB HD is a collection, conglomeration of other smaller disks, backup… It reports:
SIZE of data is about 1tb
SIZE on DISK is 1.3tb
IT APPEARS have lost 300tb of space
and usually these numbers are CLOSER TOGETHER. CHECK FOR ERRORS is clean [disk is NEW and first time use].
In an attempt to find why the 300GB difference, thought a DEFRAG might determine it.
ssssI have tried DOS cmd, tried Win 10 but neither WILL RECOGNIZE THE, ANY, USB drives and only sees, the 3 root, SYSTEM, WIN_RV??
Press the Windows key+S in the search box type Optimize. Select Defragment and Optimize drives. Select the drive you want and press the Optimize button.

This is ANY USB drive attached is NOT SHOWN on the OPTIMIZE/DEFRAG window.
ONLY INTERNAL DRIVES ARE SHOWN.
