HP Probook running Windows 10.0.15063 Build 15063
8Gb Ram / 256Gb SSD / 1Tb hard drive
Paragon Hard Disk Manager 15 Suite

I use a WD My Passport Ultra to hold the Backup Capsule (incremental SSD drive backup), a bootable partition, and 1Tb+ partition formatted NTFS P: drive for general data copies/backups. My Paragon backup (of SSD C: drive etc) works fine.

My issue is that I am unable to explore the P: drive in normal Windows, although in Safe Mode the drive is fully available. I have been around the 'Take ownership' 'Assign permissions' loop many times, both in normal Windows and in Safe Mode, with numerous partition deletes/creates in between. I have even tried unhiding Administrator and logging in, but nothing will provoke Windows to allow normal file access in DOS or Explorer.

In Paragon Volume Explorer/Hard Disks, I can browse the P: drive fully. It has been intimated that Paragon may be interfering with Windows ACL in some way? Comments and/or advice would be hugely appreciated.
