[Help] D4-320 Bay 3 and 4 won't recognize any drives [SOLVED]

[cristobal5050]

It seems that Bay 3 and 4 on my unit just don't work or do anything.

I have switched my drives around and confirmed that all drives work when in Bay 1 or 2. I have tried only using bay 3 or 4 to rule out overloading. I have tried the firmware update in the other popular post, but since the bays don't connect or show up, the tool doesn't see them to even check the firmware version.

I'm at a loss, and frankly the fact that the bays seem to be dead on the hardware level kind of has me worried that even if they start working, I may be asking for a drive to get corrupted by using it.

Whats the deal here?

It is possible the bay 3 and 4 are defective, please contact our service team for warranty service. Find the service email from my signature.

The fact that bays 3 and 4 are not working despite the fact that the drives work in bays 1 and 2 is cause for concern. Have you considered examining the connection cords in those specific bays? A defective cable may be to blame for the lack of detection. Additionally, contacting customer service may provide more insight or remedies to this hardware issue. Don't give up hope; there could be a simple solution to get those bays operating again!

Most TDAS enclosures use a backplane, not cables.

Either one of the ASMedia chips has an issue or the connections themselves on the backplane.

Make sure the SAS cable is fully inserted into the connector as shown in the left image. If it's inserted partway as in the right image you'll see the behavior you described.

That doesn't exist in one of these; here's the internals from a video review: https://youtu.be/ZdEqEWiA2CE?t=222

That's right, I had the problem with a D4-320U which does have a cable connection between SATA bridges and backplane.
