SOLVED seems NTFS app fixed the problem. Surprised because the drive was FAT not NTFS


I have an external disk CALLED "IDE" connected to OSX 10.6.7 that is locked. It has important files on it which I can read. Thus I do not wish to reformat it.
I wish to unlock it & everything on the disk. Then I wish to move some files from my Mac ONTO this external disk. The name "IDE" is historical. It is connect to Mac via USB 2.0. It is partitioned as GUID because PREVIOUSLY it was formatted as HFS+. It is now is formatted as FAT so that I can save WIN 7 backups to it.
___________________________________________________________________
Here is disk until info:
dev/disk2
#: TYPE NAME SIZE IDENTIFIER
0: GUID_partition_scheme *300.1 GB disk2
1: Microsoft Basic Data ide 300.1 GB disk2s1
_____________________________________________________________________
Here are the privileges. I don't know why 2 disks are STILL listed. Disk Util confirms it is formatted as FAT.
drwxr-xr-x 1 macosx86user staff - 4096 Jun 15 16:34 ide
d--x--x--x+ 15 root admin - 510 Jun 9 09:31 ide hfs+

Here is what I tried:
I changed my working directory to the disk "IDE"
"CD /volumes/ide/"
I verified I was in IDE using both
"pwd" and "ls". ls shows the folders on IDE which I recognized.
I then tried to unlock IDE
………………………………..
1st TRY:
"sudo chflags nouchg"
Result:
"Password:
usage: chflags [-R [-H | -L | -P]] flags file …"
………………………….
2nd TRY:
sudo chflags nouchg /volumes/ide
Result:
:chflags: /volumes/ide/: Read-only file system"
……………………..
third TRY:
"sudo chflags -R nouchg /volumes/ide"
Result: Here is snippet of what was displayed:

"chflags: /volumes/ide/ABOOKSPLUS/Bears, Greg -Quantico/Greg Bear - Quantico D11_ 20.mp3:
Read-only file system
chflags: /volumes/ide/ABOOKSPLUS/Bears, Greg -Quantico/Greg Bear - Quantico.jpg:
Read-only file system"

Hi vienna,

The MS-DOS (FAT32) file system format does not support permissions, file owners, and groups. Such permissions are synthesized on Mac OS X with some default permissions. Because of this all files will have the same permissions, which include having the execute bit being set. This means that files with an unregistered extension appear as "Unix Executable Files" in the Finder, with a Terminal-like icon.

That isn't limited to the home folders. Maybe some Windows utility recommended here might be worth a try too.
 
1. Thanks for the lesson on permissions in WIN 7. I should have known that.
That was one of the big weaknesses of Windows.

2. Got NTFS.
it now works
I can paste onto the fat drive and copy from it.
