Asus B760-F not seeing Crucial T500 in the bios

[Yozzer]

I bought the Katana which is working well. It uses the Asus B760-F and my son has bought me a Crucial 2TB, and installed it with no problems in the M3 slot which was empty, the WD M2 which contains Windows 11 is next to the CPU and works fine, though I have not moved it at all.
The problem is the T500 is not seen in the bios, so of course does not show up in disk management. I tried enabling CSM mode as I saw mentioned somewhere, and also tried it in the other empty M2 slot, but no luck. He bought the drive off Amazon, so can return it, but I wondered if we had missed something silly. I do not have a caddy to try it on USB. I also do not want to move the existing WD drive, as the PC is new from Overclockers a short while ago, and do not want to mess with it. Hope you can advise me.

Hi, thanks for the reply. This is a new PC, and the first thing I did was put the latest Bios in, you are not wrong, the one in it was from when the motherboard was built. My son just arrived a little while ago, and we tried a Samsung in which worked fine, and he also had an enclose for connecting the M2 to USB 3.2, and we were able to format it, and write to it, but the enclosure was an early one so speed was no good, but I wanted this to work inside. We will try some more, but it is clear Cruicial have a compatibility problem, or Asus has.
