HFS+ Mac OS 9 drive (also used under modern OS X) - locked folder/access privileges

[Byrd]

Hi all,

I've HFS+ formatted 120GB CF drive, running Mac OS 9.1 that I physically plug into a Mac Pro running Mac OS X Monterey to copy a 60GB MP3 collection over to ("Music" folder from the default location in OS X).

An issue I've found is once the drive is plugged back into my Mac (a TAM in this case), the "Music" folder is locked (small icon with pen with red cross strike through). Any attempts to copy or delete files from this folder in Mac OS 9.1 results in a "you do not have the privilege to make changes".

My old friend ResEdit refuses to unlock the Music folder, stating similar privilege issues. Plugging the drive back into OS X, there are no privileges set.

Is there an utility under OS 9 that'll let me remove the folder privilege lock?

Thanks

JB

I wonder if OS 9.1 thinks it’s running as Classic under OS X.

Does rebuilding the desktop for this volume under OS 9 make a difference? Also, when under OS X, is the "Ignore ownership on this volume" box checked when doing get info on the disk?

In Mac OS X, do you have the "Ignore ownership on this volume" checkbox unselected?

Then check the permission of the folder and ACL and extended attributes and file flags.

ls -lAOde@ ~/Music
drwx------@ 6 joevt  staff  - 192 22 Feb  2022 /Users/joevt/Music
    com.apple.FinderInfo     32 
 0: group:everyone deny delete

Use the -n option to view user/groups by ID since these may differ between OS's.

ls -lAOden@ ~/Music
drwx------@ 6 501  20  - 192 22 Feb  2022 /Users/joevt/Music
    com.apple.FinderInfo     32 
 0: ABCDEFAB-CDEF-ABCD-EFAB-CDEF0000000C deny delete
