860 EVO mSATA not recognized by Samsung Magician

[user0IXEva52Z7]

It also does NOT show up  in Windows 10 Disk Management, but the 860 EVO DOES show up in my Lenovo T520 BIOS as HD2.  I have a SATA HD as HD0.   BIOS AHCI is enabled.

It was purchased brand new a couple of days ago.

Other than AHCI, the BIOS has a SATA compatibility option.  Should I try to enable it, instead of AHCI?

Is this SSD dead?

Thanks

Setting BIOS to SATA Compatibility Mode causes HD boot failure.

The Lenovo T520 mSata slot is a Serial ATA-300.  The 680 EVO mSata, should be backward compatible with SATA II.

I dont understand it.  But all of a sudden, the SSD is being recognized by both Magician and Windows 10.
