ssd SSD not found in Windows

[Matthew J Johnson]

What would I do if I installed an SSD.  But Windows won't find it even in partition.  But BIOS finds it right away.  Defective SSD?  Its a old Toshiba 256GB SATA M.2 being inserted in a compatible slot.

Have you partitioned the drive in Windows? https://kb.plugable.com/data-storage/plugable-tech-tips:-how-to-partition-and-format-a-new-hard-drive-(or-ssd)

No the drive was pulled from a Dell.  Then used in a Msi for a while.  As far as I'm concerned it still has Win 10 on it.  No it was not partitioned.  Nor shows up in the Windows partition app.  When I get a proper adapter I was going to see if a Mac can find and wipe it.

You could try running something like DBAN on it, but I would use it as a last resort as it shortens the drive lifespan by writing 0's to every cell. If you do go this route, unplug any other drive to avoid accidentally erasing another drive.
