Cannot save files onto logical drive (partition)

[bawldiggle]

My new external HDD has 3 logical drives
- no Primary partitions

The three logical drives are J,K, L + one unallocated area


I cannot save files directly onto any of the logical drives



I can ...

1. create folders directly onto the drives
2, not save files directly onto the drives
3. save files into folders on the drives J, K, L
4. save files directly onto C:\ but not directly onto J, K, L drives
​

I am a newbie to partitioning and using Mini-Tool to create partitions
- determined to work it out for myself but now I need help

Q1:What have I done wrong ... or what am I missing ?

Well; one of the quirks with windows 7; is that even if your user name is set as administrator; you need to "add" your user name to the administrators group in order for you to obtain full access because for some odd reason; Microsoft decided to design the default access for administrators so that even with being a admin; unless your user name is a member of the actual admin group; then you will probably get errors like that. Try assigning your user name to the admin group then try and save and see what happens.

Thanks matts6887

Would I apply the "user" (me) to each logical drive, or just the first drive "J"

And how do I do that ?
- the last time I did anything with privileges was about 2 years ago

If the HDD is connected to another PC I would have to establish "me" as part of that machines admin group ?

This is my first dalliance with changing security privileges ... on trainer wheels

Group or user names (list) ... "Full Control" settings
Everyone:- Allow [ ] | Deny [ ]
Creator Owner:- Allow [ ] | Deny [ ]
System:- Allow [x] | Deny [ ]
Administrators (Owner-PC\Administrators):- Allow [x] | Deny [ ]
Users (Owner-PC\Users):- Allow [x] | Deny [ ]​

... why all these variations of "Security" ?
Can these be thinned-out, or are they all "required"
- this is an external HDD with 3 logical drives J, K, L
It is not imperative that I save files directly onto drives, I can live with the current protocol, of saving into folders
- now very curious as to why the zealous security settings by default
- I have a mutant "why?" gene

Thank you ...
