So yeah , my 980 pro is not recognised by the samsung magician right now , let me describe the course of events:
1. installed the drive and turned on the computer
2. samsung magician recognized the 980 pro and offered a new firmware
3. installed it and the firmware update turned off my pc by itself (so it went good i guess (?))
4. turned on my pc and now the 980 pro is not recognized by the samsung magican
the samsung magician was at the latest firmware version (7.0.0) , same goes to my motherboard bios
i tried to downgrade samsung magician to 6.3 and 6.2 , didn't change anything, the bios settings for the was already ahcl ahead of installing , and still now, every other program recognize the drive , the drive works fine (pcie 3.0 speeds since z270, but still, till i upgrade cpu and motherboard).
tried as well to install samsung nvm express driver (3.3) , but i get an error for :
"Samsung NVM Express Device is not connected. connect the Device and try again.
i'm clueless to what cause that, i think the firmware is corrupted after the update, no clue how to fix it (that's why im posting here), and its frustrating since i can't use it for its purpuse since the samsung data migration is not recognizing it either. both the program recognize my 860 fine (860 to 980)
(the drive is D:\)
cpu: i7 7700k
ram: corsair lpx 3200mhz 8GB*2
motherboard: gigabyte z270hd3
ok , so i solved it , windows trolled me , in case anyone else is expriencing the same symptoms with his drive, it was caused by windows with its storage pool (just delete the storage pool) and it will fix it.
