I have a couple of FW drives hooked up to my iMac and I just discovered I can't trash anything from them. Actually, ever since upgrading to Lion I've been having all sorts of permission issues, but that's another discussion. In this case I've gone to the info windows for these drives and I have only read premission and I can't seem to change it. I've done all the usual things to do so but it remains stuck on "read only." I'm regularly repairing permissions so I don't see that working, tho I haven't tried trashing anything from these drives in a while so I don't know how long it's been this way.


Any ideas?

    Rapairing permissions with Disk Utility doesn't really take care of all permissions issues.  It just checks the listing for major applications and things that have been installed and repairs those.  It doesn't do it for a bunch of data files put on external drives.


    If you only use these drives for data storage as an accessory to your computer I would get info on a drive and select the "ignore ownership on this volume" feature.


    Having said all that, I suspect there is something else going on. You say you have several drives. How are these all attached? Daisychained?  In theory you can have a large number of FW drives daisychained. In reality I have seen posts where not all models really like having other drives plugged into them.  Erratic behavior (and I am not convinced all your repairing permissions and zapping PRAM really did anything about the issue) might well be due to glitches in the chaining.
