Question m.2 only visible on BIOS

[pav16]

Hi all,

Got it cheap from eBay recently, nothing to write back home about, 10th Gen i5 Precision 3440 which was listed as 256gb in fact there is another identical 256gb m.2 in it.
The thing is spotless, hardly any dust inside both m2's have cooling pads underneath, however despite both are visible in BIOS, only one is visible in Win 11.
I went through quite a few threads without luck.
Diagnostics all green, swapped them round, no issues, booted okay.
Was wondering what else should I try?
There's no disks visible in pools to delete, also deleting storage controller never helped.
Any help would be greatly appreciated. Cheers

What does w11 see for disk size?

Test with one disk at a time what happens?

It is raid 1 which explains it, thank you for pointing me in the right direction 🙂

Who set up this RAID?

Got "it" from ebay...what is "it?

Are you trying to set it up as a RAID partition? Or are you just trying to use it with Windows as is? If its option 2, you need to initialize it in diskpart.

If this is a used PC you bought from fleabay, you NEED to do a full wipe and reinstall of the OS, and completely wipe any other drive(s).
