On every darn ext drive I plug into my pc on W8.1? Either they are formatted NTFS, exFAT, FAT. What the hell? This is a fresh windows installation. No updates just a sole Windows 8.1 with Update 3. After spending 3 days configuring I noticed this issue. What a disgrace. Note: I've done many Windows installations before as I'm a pc technician, that says it all, and never ever encounter this issue before... damn.
