Weird USB behaviour

Hardware:

RN204 @ 6.6.0 with 3 WD 4 TB Red and 1 Samsung 1.5 TB

 

Sabrent 2 bay USB 3 docking station

Toshiba 3 TB

WD 4TB Red

 

2 brand new Segate ST4000DM000 4 TB

 

I have been using the WD and the Toshiba in the Sabrent to back up the RN204 for six months or so. No problems.  Micro Center put the Segates on sale for $100 so I got a couple. Planed to replace the antique Samsumg with the USB WD Red and put both Segates in the docking station.

 

Now comes the weird part.  The RN204 will not recognize but one of the two Segates at a time. I used my Thinkpad to format the Seagates and it had no problems seeing both drives. But when I plugged the docking station into the RN204 only one drive showed up. Did a lot of experiminting.

 

The RN204 can see a Seagate and the WD 4TB Red at the same time only when the Seagate is in slot one of the docking station. With slot 1 empty a Seagate is never recognized in slot 2. With a Seagate in slot 1 and recognized, I can plug the other Seagate in slot 2 and the RN204 disconects slot 1 and activtes slot 2. The WD will work in either slot with a slot empty.

 

Since any combination of drives/slots works when pluged into the Thinkpad, then is this a Netgear problem or a Seagate problem?

    Bought an inateck FD2102 USB3 Dual Docking Station from Amazon.  It had absolutely no problem bringing up the two Seagate 4 TB drives. Have been backing up from RN204 to it for five days now. Working great.

     

    So since Sabrent does not support USB to anything but Windows or Mac, then the solution must be to not use Sabrent. Or Seagate?

     

    I had thought that since the interface was USB that the operating system would be irrelivant.

     

    I do see that the inateck box says "Support OS:  Windows XP, Vista, 7, 8, 8.1 (32,64 bit), Mac".  So, offically, it does not support Win 10 or Linux.  But it had no problem formating the drives to EXT4 on the RN204.

     

    I bought my first PC in 1982.  After 35 years I should be used to doing this stuff by trial and error.

      Had not seen that. Unfortunately I tried hot swapping, powering down the docking station and rebooting the RN204. Nothing helped.

        Just dawned on me that the Thinkpad is USB 2.  Tried pluging the docking station into the front of the RN204 which I belive is a USB 2 port. Can only see one drive. Plugged docking station into Mac Mini (USB 3) running Windows 10. Both Seagate drives come up immediately.
