I have several Samsung SSD 2 TB external hard drives and I have been having some issues.
When I create a file, or foulder on my home PC running Win 7 Pro, and save it to my Samsung external hard drive, I cannot see the files or foulders on my work laptop running Win 10.
I have access to the external and can read and save to it just fine. Just not the files I create on, or coppied from my home PC.
There is no security tab on these drives to check that (I'll search for that next), and "show hidden files and folders" is checked in folder options.
