Hi.
I have two WD external 2.5" disks:
WD Passport Ultra 2TB and WD Passport 4TB
Both drives are working flawlessly on my HP notebooks, but I have problems on my desktop computer based on Intel Z97 - Asrock Z97M Pro4.
WD Passport Ultra 2TB is working great but when I connect WD Passport 4TB computer recognizes it but I hear metal sound clicking and I cannot read anything from disk. It seems like disk has not enough power. I swaped USB3 cables between disks but nothing changes.
How could it be that Ultra is getting enough power on same USB port on same computer? Maybe problem is with chipset, firmware or drivers?
