How hard can it be?

[2J4EZ]

Ive just got my self a 4gb CF card to use in my amiga so i can do a fresh install of workbench 3.1
I not normally  a windows user however i have 2 laptops just done a clean install of windows on both to use winuae.
Ive been trying 5hours last night and 3 hours this morning to get the card to format and install workbench on it.

Problem 1
The amiga comes up with a error about type 7 or something so i tried doing it on WINUAE.

Problem 2
WINUAE wont let me format it because of admin rights (im the admin of the computer)
using diskpart to clean it make the disk unreadable winuae see the disc,but HD toolbox does not see it. and the only way to get it back it to format it on my mac.

Any other ideas i can try?

First of all thanks for the replies so far.

Ive followed all the suggestions and they seem of to worked.
I ran winuae as admin (which i did before and did not work?) also ran diskpart as admin.
after running diskpart and following the commands as admin my card was not useable in windows but WINUAE found it and so did HD TOOL BOX saved changes to the harddrive and no windows error.

Restarted the emulator and ran install 3.1 disk a few seconds later 2 drives popped up saying:-
System NODOS
Work NODOS
Just formatting them now i should be able to install WB3.1 on one of those drives

Fingers crossed
