I use two bare 3TB drives for backup and on/offline storage on an MSI X-power mobo, Win10. Normally I use them via E-SATA (AHCI on one of the mobo's Intel ports, not its Marvell or JMicron). Two questions:
1) When they are both in the Thermaltake BlacX Duet dock, only one is seen by the BIOS and by Windows. I'm sure that with previous HDDs and Win 7 I was seeing both, so the mobo port multiplier function is OK -- does something in the dock or BIOS have a problem with two HDDs that big on a single physical SATA port?
2) To work around that, I tried connecting one (previously initalized and used via ESATA) to a known good USB 3 port,via a Seagate GoFlex connector. It shows up in Drive Management as a "healthy GPT protected partition", but all disk and partiution actions are grayed out so I can't give it a drive letter. In Properties-> events I read
Device USBSTOR\Disk&Ven_Seagate&Prod___FA_GoFlex_Desk&Rev__D18\01234567&0 could not be migrated.

Any suggestions on either or both would be appreciated.
