Linux cannot detect SATA ssd

[dushyant28]

hello,
thanks for the help.
the query is solved.

firstly i make a seperate folder in the linux and then mount the ssd
first i mounted by the command 'mount dev/sda/folder name and then
by using 'mkfs.ext4' command it can make the space for the new drive.
and after that i did df -hT command to check the space.

thank you so much for the help

Something is amiss here. m.2 ssd's are nvme not dev's.
My ssd is 'dev' mount '/dev/sdaX'. Can leave RST in BIOS
My m.2 ssd is nvme as in /nvme/sdaX which need AHCI in BIOS if dual boot.

You show m.2 ssd as 'dev' mounted and not 'nvme'

Not necessarily. M.2 is just the form factor: the drives themselves could be using SATA, PCIe/AHCI or PCIe/NVMe, depending on the capabilities and configuration of both the drive and the host.

ssd's are different type. mine is not NVMe, just sata ssd. NVME's are other kind and they are faster than sata ssd.
so it creeates /dev/sda. and i have to mount to the system inside some folder.
so i first created a folder and then mounted
/dev/sda/<foldername>

I've never seen an m.2 that wasn't nvme. I'll have to find one. I do know mine plainly states on the box nvme. I mistakenly thought they all were.

My motherboard says this:

The M.2 connector supports M.2 SATA SSDs and M.2 PCIe SSDs

When I built system several years ago NVMe drives were expensive, so I have a SATA drive plugged into the M.2.

Fred, does you m.2 have "1" slot or "2" slots on the connector side?
I just read the "1" is NVME, and the "2" is SATA

[oldfred]

I think mine only has one. Do not remember and manual only says connector.
Also if I use M.2 as SATA, then first SATA port (SATA3_0)is taken or not usable.

sata slots are different kind. they have B key, M key and B&M key. what I am using is B&M key. and motherboard have eithe B slot or M slot. nvme is different. when you buy ssd, it is cleasrly mention what kind you want to buy either key version or nvme version.

how do you check this H/W path ? and also after switching on the system i have to again mount my ssd by using command in linux.
is there any command by which i dont have to mount again after i switched on the system?
