Thnks Joe, I don't know what NAS (Network Attached Storage) mean, or extension or anything really.
Ok I'm in DU
1 APFS.
And OS extended Jouranled.
2
SB External Physical Volume • Mac OS Extended (Journaled)
GUID partition Map
3 same as 2
Can't imagine any of these have anything to do with new Laptop coming, unless I try to access stuff via home network, which I don't too too much, but sometimes...(rare)
For #1, is the drive partitioned? Seems that way, as you state DU is saying APFS and OS Extended Journaled. A volume is formatted as one or the other, not both.
