Cubase is not compatible "WD My Passport Ultra 3TB (USB3.0)"

Cubase is not compatible “WD My Passport Ultra 3TB (USB3.0)” on windows

This drive (with hardware encryption function)…

When I create Audio Track from “WAV file” on it,
“Disk Cache load” is always full.(very often)

I tried…

Cubase 7/Cubase7.5/Cubase8
NTFS/exFAT/FAT32
Windows7/Windows8.1/Windows10
3 notebooks and 2 desktops.

Of course, drive is not broken.
All other software are no problem with it.
I wrote 6TB data to it ,but it had no problem.
S.M.A.R.T is OK.chkdsk is OK.
wav/aiff/mp3 are NG. but flac is OK.

Any other USB3.0 drives I have are no problem with cubase.

I think cubase is not compatible with WD’s “hardware encryption chip”…??
(Of course, I disabled it.)

I’m sorry my poor English.
