exFat SSD

[HeLiOn]

I formated an NVMe SSD and made it exFat.
Now it's not detected anymore. Not by Disk Manager, not by Diskpart, not even by a Linux boot drive.
Is there any way I can deleted the partition and turn it back to NTFS?

Does it appear in the BIOS?

 

Do you mean the physical drive no longer appears, or just that there are no partitions on it anymore?

 

Can you post a screenshot of Disk Manager?

If you are comfortable with Linux you can give Gparted a try. Otherwise consider checking with something like the CLI fdisk utility.

 

Ex. sudo fdisk /dev/nvme0

 

This assumes the device is recognized and linux assigned it the friendly name nvme0.

I haven't used fdisk in a minute but you can also have it list the command options I think it was p to select a partition, d to delete, and when you're done, w to write the changes.

 

This should let you delete the device exFAT partition. There's other functions as well like setting the device to use GPT but be warned this will risk deleting any data you have saved on it so be wary.

I think I figured it out.
I connected the drive to the motherboard through a PCIe 1x adapter, because all the M.2 slots were already occupied
The drive and the adapter ar both functional, but it seems the adapter doesn't connect properly with the motherboard through that slot.
And it just so happened that the connection got loose sometime after I did the format.

I guess we can count this one as closed.
I'm sorry for wasting your time, but it took me quite awhile to troubleshoot this, in the end I got another PC to check the adapter.
