Suddenly Ubuntu only sees 4 of 5 hard disks. Anything to do/try?

Recently Ubuntu stopped mounting (or even seeing) one of my hard disks. I assumed the disk had failed so I replaced it only to find it's not actually the disk itself. It seems to be something to do with one of the SATA connectors. But it's not "dead", Ubuntu is seeing the disk but not attaching it.

I wondered if there is anything I can do/try to resolve this?

When I connect a disk successfully I get the following dmesg output:

I have Ubuntu 22.04.2 LTS with a MSI Z170A motherboard. It has 6 SATA 3 connectors and I have 1 internal HD and 4 hot-swappable SATA caddies all with hard disks.

They are not the same ... The disk specs, vendor, and model number are not identified in the second case ... This problem looks limited to the caddy and cable at the 5th SATA connector ... Swap them with either of the other working caddies with their disks and cables ... If 5th SATA works then you know what to do and if it doesn't work then the 5th SATA connector on the board is probably damaged and there is not much to do about it ... Nothing to do about it in Ubuntu either as it looks purely hardware related.

@Raffa thanks for the reply, I had a play with cables and it seems like it's not the caddies or cables so it must be the motherboard storage controller/s. It looks like the 5th (and also 6th) SATA connectors no longer work properly for some reason. Hopefully I can just buy a PCIe 3.0 SATA card to work around the issue?

There are multiple different solutions for that … But, the most recommended are only two AFAIK … 1) A PCIE SATA card offers the maximum performance and gives you more connectors/channels … 2) A RAID enclosure to SATA is cheaper with probable performance penalty and gives you more disks/bays per an existing SATA connector … The rest of the alternatives e.g. port multiplier/hub are a waste of both money and performance.

PCIe can be expensive .., So, I would compare that to a new motherboard of the same model as the existing one and change the motherboard instead if the price is close … This will not only provide 6 working channels but a new motherboard as well to add more years to the life of your computer .

An update for anyone else in future - it did seem to be a hardware/motherboard issue where the 5th and 6th SATA ports stopped working correctly.

I saw StarTech list Linux compatibility so I purchased a StarTech 2P6G-PCIE-SATA-CARD for £33 in the UK and it seems to work fine, no config required.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
