I purchased a SABRENT EC-HD2B 2.5" & 3.5" Black SATA I/II/III USB 3.0 USB 3.0 to SATA I/II/III Dual Bay External Hard Drive Docking Station It works, but appears to be impossible to re-mount a drive once it has been ejected.
On a Windows 10 64 bit system, this docking station appears in Device Manager as "Sabrent Dual SATA Bridge SCSI Disk Device" (Compared to most external drives which are listed as "USB Device" under Disk Drives)
The USB eject/reconnect does not work with this UAS dock. After ejecting the drive (aka safely remove), any drive in the dock will never be recognized again until the computer is rebooted. After I eject, turn off the docking station power and/or unplug USB, the drive (or drives) will not be recognized again when reconnected. Device Manager shows it as a Storage Controller named "USB Attached SCSI (UAS) Mass Storage Device" and has this error: "Windows cannot use this hardware device because it has been prepared for safe removal but it has not been removed from the computer. (Code 47) To fix this problem unplug this device from your computer and then plug it in again."
Even after powering down the docking station, unplugging and replugging the USB connector multiple times, the error remains and the drive/controller is not recognized. Attempting to disable and re-enable the UAS device in Device Manager results in the message: "Hardware has changed - you must restart the system"
This issue defeats the purpose of an external drive - being able to remove and reconnect without restarting the system.
Except for this problem, the dock works well. I'm looking for additional docking stations, and am trying to determine if this is just a bad product, or if there is a Windows limitation preventing the re-mounting of UAS. Does anyone have a UAS drive dock that can be removed and remounted without rebooting?
