I bought this


And replaced the DVD drive in my laptop for a second hard drive. Linux Mint is not recognising either of the two hard drives I've tried.

Can anyone help me troubleshoot this please?

Are the drives showing up in BIOS? If not, take the tray out and compare it with the DVD drive to make sure the dimensions are right.

Hey up. Thanks for taking the time.

Yep. The BIOS doesn't show any of the drives, not even the one it's booting. Really bizarre. I'll try and take some pictures so you can see what I mean.

I am 99% sure the thing really is plugging into the connector.

If you can't see the drive you're successfully booting to, you're doing something terribly wrong. Try again.

when you say linux mint isn't recognizing either drive, do you mean you're booting mint from a live USB stick?

No, I am booting linux mint from /dev/sda1.

It is not recognising either of the (physical) hard drives I tried for /dev/sdb.

Yep obviously I was wrong.

This is apparently for disabling various drives. Why would I need that.

Sadly the boot sequence doesn't seem to have the option I need ...

I don't suppose you decided to replace the DVD drive because it wasn't working.

nope, the DVD drive was working just fine.

So stick the boot drive in the tray and if it doesn't come up you can conclude that the tray is defective.

RAID means redundant array of inexpensive drives. there's several levels and the two main ideas are to either mirror or stripe the data.
mirroring means 2 drives have identical copies of data, if one dies the other keeps going. striping means every is cut into blocks so half are on one drive, and the other half is on the other. speed is exactly 2x since you're reading and writing in parallel, but if one drive fails, you've got confettis left over.

also you should be using AHCI, not RAID

Not about AGCI but raid has generally been used for servers., production environments. When something is changed in the original drive, the others
would update om the fly.

The RAID setting enables AHCI, RAID, and RST. It does not imply that RAID is going to be used. Kind of a bizarre label consider what it does.
