HELP! trying to transfer purchases from my iPad but keep getting: "you do not have enough access privileges for this operation" message

Question

I recently had a hard drive crash and lost almost everything except for what I managed to save on Carbonite. When I got the new hard drive, I updated to Lion and began the laborious process of restoring my files. I think it is up to 40% done.
Anyway, I went to try to transfer my purchases from my iPad2 (4.3.3) and received the message:  "You do not have enough access privileges for this operation" followed by: "Attempting to copy to Hard drive failed. You do not have enough access priviledges for this operation."
So, I did a search on the problem and have found similar complaints and some reasonable suggestions, which I attempted without success. So far I have:
1) Rebooted
2) Changed all the Permissions on the iPhoto Library and iTunes folders to Read & Write.
3) Used Disk Utility to Verify & Repair permissions.
Nothing is working.
HELP!

Had the same thing happen to me a few weeks back when I switched computers and migrated.  Here's what worked on my iMac, so maybe it'll work on your iPad, too.  Go to User(your home folder)/Music.  Select/highlight your "Music" folder.  Then do Command-I ("Get Info" from the File menu), click on the padlock icon in the lower right of the new window.  Enter your user password.  Click on your username just above the now-open padlock.  Select "Read & Write" if it's on "Read Only," "Write Only," or "No Access."  Now having your user account with "Read & Write" privileges (it may have been this way already; still do this next step), click on the gear on the bottom-center of that window.  Click on "Apply to all enclosed items."  When the pop-up says "Are you sure?" (or the equivalent), say "yes."  This will grant access privileges to your user account for all the music files inside your music folder--all your iTunes stuff included).  Then you should be good to go.
