Solved No Write Access to Two of Three WD Disks On LAN

[NewW7User]

I have three WD disks (same models) attached to computer 1 on my LAN. I have the sharing set to "Everyone" with full write access. But computer 2 on the LAN can write to only one of them - O-disk. When I try to write to either of the other two - P-disk or Z-disk - I get a message "You need permission to perform this action". What am I doing wrong - or not doing that I should be doing?
I've attached screenshots of the sharing settings on computer 1 for each disk.

You can set share permission to eveyone but then you need to set NTFS permission or you can access it as folders will be owned by the creator have you set that?

I did not set that on any of them as I didn't know about them and don't know where to set them. Yet one of the three disks does have write access, anyway.

Thank you Samuria. I now have NTFS set to allowing full control and it is working.
