I see that your BIOS has (or may have, the manual is fairly generic) things like drive-lock (*). Also unlikely to not provide uniform behaviour over Linux and Windows but can you scrounge around your BIOS settings? You seem to at least have a fairly configurable BIOS; does the drive show up at all in there? Do you see an AHCI option anywhere? As said, things like drive-lock, ....

Nor I. Given that the libata.force did not work I've essentially no idea. Maybe the "look through the BIOS" thing still reveals something but I doubt it.

Re: Laptop Optical Drive HDD Caddy Not Recognised

I have had a look through the laptop's BIOS, but can find no reference to the HDD in the caddy anywhere - not in the boot options, under "Drive Lock" or the BIOS's built in drive tests - only the original SSD appears. Also, no mention of "AHCI" that I can see, neither in the BIOS nor in the linked BIOS manual.

I am wondering if the HDD caddy mounts in Windows after the BIOS has loaded, but during Window's startup - possibly using "Microsoft Virtual Drive" which seems to be built in to Windows 10?
https://docs.microsoft.com/en-us/window ... hard-disks

However, I do not know how to tell if this is the case. Is there a Linux equivalent of "Microsoft Virtual Drive" that I might need to install on the laptop?

Not an HP user, but wonder if it has one of those awkward BIOSes that require a supervisor password to be set before you can see/change certain settings?

It's the 'works in win' that's bugging me. sata mode not set = AHCI remains my best guess. That would be something that would work in win and not linux.

I have just tried setting a BIOS Administration, (HP term), password and rebooted into the BIOS. After entering the new BIOS password I cannot see any settings or information that were not there before. I have now deleted the Admin password, (before I forget it!).

Searching through the BIOS manual, (linked previously), again I can find no reference to "AHCI", and the only references to "SATA" say that they are only applicable to desktop systems.

I'll give it a day or so to see if anyone else chips in with suggestions, but I'm thinking that this is unfortunately unlikely to be resolved and I am going to have to restore the HDD to its original external USB caddy?

Thanks to those who have tried to help so far :)

Something else that has just occurred to me:

Am I right in thinking that sometimes Linux kernel upgrades can break previously working systems? ISTR having a netbook a few years ago whose built in display stopped working after a kernel upgrade. Luckily the VGA output was still working so I was able to roll back to an earlier kernel.

Would trying an earlier Linux kernel help here, even if only for testing purposes? The earliest I can find in the Mint GUI is 5.4.0-26 - are earlier versions still available, and how would I go about installing them? (I'm thinking about say a version 3.x or 4.x kernel).

Earlier kernels - there is mainline, but last time I looked the earliest kernel it had was 5.0. Can't remember if it is in software manager/SPM (I've got it installed).

Want earlier, e.g. 4.15, then you want UKUU. This is no longer free, but if you search the web you might still find V18.9.1 which is free (and what I have installed). Just had a look and yes you can:
https://github.com/teejee2008/ukuu/releases

Note - installing a mainline kernel should be viewed as for 'testing only' as they don't have the tweaks introduced by ubuntu/mint, not sure if you get updates either. I've done it in the past to troubleshoot a monitor that wouldn't work in LM19+ at its native resolution 'out of the box'. Worked with any kernel up to 4.5.7 but no later.

While it's worth a shot, my hopes are not high.

Where in the UK are you?

EDIT - do you still have the DVD drive that goes in the bay and is that recognised in linux? I'm assuming that it will be on a sata interface.

Thinking about it, (and noting your warning), even if reverting to an old kernel did get the caddy to be recognised I would not be able to safely leave it running on an out of date kernel, (would I?).

I have just pt the laptop's original DVD drive back in and it is working fine, so I'm probably going to leave it like that - unless anyone else comes up with anything to try.

I am in the North Buckinghamshire area - why do you ask?

Can definitively not think of a reason why if the DVD drive works and the disk does in Windows that there would be nothing to go on in dmesg in Linux. If we'd see some form of IDENTIFY error or something, sure, but now no idea I'm afraid :(
