When connecting an external USB 3.0 hard drive to my USB 3.0 ports I can never safely remove it.

Somehow windows always keeps the journal files open: enter image description here "Always" as in this time I only connected the drive, copied a 10GB VM and wanted to disconnect it afterwards (like 15 minutes after copying, so all copying was done).

As you can see there is no other program keeping a handle on the disk besides System. I tried restarting explorer.exe as well as RemoveDrive.exe from Uwe Sieber. No luck, the locks on the hard drive always remain.

My only solution is just unplugging it (whereas I'm afraid of damaging the data?) or restarting the computer (always helps, doesn't it?).

Might it have something to do with me only having a SSD hard drive and the external disk is a regular drive? Might it have something to do with the USB 3.0 drivers (NEC Electronics USB Hub)? I never have this problem when using the regular USB 2.0 ports.

Any ideas on how to properly unmount the disk?

    Hi, A friend of mine destroyed his Nvidia RAID1 array somehow and in trying to fix it, he ended up with a non-working array. Because of the RAID metadata, the actual disk data was stored at an offset from the beginning. I was able to identify this offset with dd and a hexeditor and then I used losetup… >>> More
