I got a used HP laptop and I opened up the back and I see what looks like a M.2 drive and a 2.5" drive....
I tried to just use the M.2 drive by unplugging the 2.5" drive, but the system won't recognize any drive.
The M.2 drive is 256 GB
The system had a 500 GB mechanical HD... So I replaced it with a 128 GB SSD.... And it's only showing 128 GB.... Can I just use the M.2 Drive?
Go to Solution.
It's used. It's possible the M.2 SSD is bad. Here is the Service Manual:
Have you run diagnostics on the M.2 SSD?
Thanks for the reply... yeah maybe the M.2 SSD is bad.... I don't even see the M.2 in the BIOS, so I can't test it... I'll see if it shows up on Linux,....
Is there is a setting that forces the M.2 as a cache for the 2.5" drive.... and can I change that setting?
If not, I'm guessing the M.2 drive is dead...
That is called Optane and yours does not support it. If it were an Optane setup the M.2 would be 32 gigs or less capacity.
Thanks, yeah I thought 256GB was a big cache...
Ok I tried a m.2 nvme drive from another computer and it worked!
So I guess that old drive is dead. Thanks for your help!
