hi there

i have been having trouble running two hdds as slave

my 1tb is working fine
the problem is the other two a 1.5 and a 2tb Samsung is picking up in the bios but not in windows 10. i have been in device manager and disk partitions.

I am running AHCI and i have updated the bios already.

both drives are fine cause they work on my external.

Were the hard drives formatted in Windows 10 or Windows 7 or lower?
