Rosewill HDD dock incompatible problem

I have 6 USB 3.0 HDD docks that all claim to support more than 2TB drive (as a USB 3.0 docks, they should). Unfortunately, two Seagate 3TB drives that are formatted in one group of docks are not recognized in the other group. One group consists of two identical model (I think older) Rosewill docks, and the other group consists of 3 Orico docks (different model) and 1 Rosewill dock (I think newer than the 2 in the other group). The problem is that drives (in this case, 2 Seagate 3TB drives) that are formatted in the 2 Rosewill docks group (default setting, NTFS, single partition) cannot be recognized in any of the other 4 docks (they work fine in the 2 dock group). Using Disk Management, in the 2 dock group, they showed up as one 3 TB partition and OK. Plugging into the 4 dock group, they showed up as a drive with 2 partitions: (1) 2048 GB, Healthy (GPT protective partition), (2) 746 GB unallocated. Cannot do anything to the partition under that situation as all functions are whited out (only Help & Property functions are available). I don't want having to connect the drives inside a pc in order to reformat them. Could someone enlighten me what is going on? Thanks in advance.

I agree.

There were so many docks that had such limitations. When I ran into such docks we replaced the docks with new versions and sold the old out of date docs for 2 bucks each and no warranty.

What can I do

So you are saying that those 2 older docks are problematic and there is nothing that I can do to reformat the 2 drives without having to connect them directly via SATA to the pc? That, or continue to use those 2 docks with only the 3TB drives (they also work with drives below 2TB)? May be in my next pc build, I will first transfer their contents to temporary place and then connect them via SATA for reformat (then dump those 2 docks)?

I shared what we did.

Your solution can be similar or what you find to work. My reply is that we ran into dock problems and given we don't want to futz with such what we did.

Maybe Rosewill has some fix but that make is known to make things then forget they ever made them. That is, no fixes for the cheap stuff.
