Hello,

i recently bought a D2-320 and filled it with two 16TB harddisks from Toshiba (N300).
I use the D2-320 in Single mode, because i want to use both harddisk indepently.

Both drives are in the case, and when i start the device everything is alright.
If i want to stop just one of the harddisks (safe eject under Windows) then both harddisk get ejected.
Same problem if i use the supported hot swap. If i pull out one harddisk out of the case then the other gets ejected under Windows 10 22H2 or 11 23H2.

I am aware that i simply could do:
1) eject both harddisks under windows
2) pull out one of the harddisks
3) turn on the other harddisk case
Same way would apply if i want to pull in the second harddisk.
But this isn't the way i would go, because its totaly stupid to do it that way.

Is their any possibilty two change this behaviour?

Under the FAQ section i didn't find a solution.

Sorry, i have to correct my first post.
The D2-320 has no Hot Swap, that i've tested one time.
This was my mistake.

But the problem, that both drives get ejected when i just safe eject one drive is there.

This is normal because it is a RAID device and when you safely eject any one drive, both drives will be ejected.

I was considering a device such as this to expand my system. However, if it cannot recognise single drives - as claimed in the product in the product documentation - as a pure single drive, it would seem pointless. {Hint: The OP said it was in single drive mode.}

Thanks for the reply.
If i would use the D2-320 in RAID-Mode (0 or 1) or JBOD, then it would make sense.
But as is wrote and Gremlin confirmed it, i just use the Single Mode.

The installed Controller inside the DAS should know this, otherwise the Single Mode would be superfluous.

Due to the hardware RAID controller configuration of the D2-320, you cannot eject one of the two hard disks individually, even if they are in single mode. This is a limitation imposed by the hardware specifications of this model. If this model does not meet your requirements, please consider selecting the D4-320 instead.

Thanks for the reply. Must say, I would have thought D2-320 and D4-320, (both being "320") would have the same underlying hardware, with just the expanded chassis, but I now see they don't.

Slightly off topic. Would the D5/D8 hybrid exhibit the same behaviour?

Yes, Models equipped with hardware RAID controllers exhibit the same.
