I reinstalled Windows on my computer today, and backed up my music to a USB drive. Now, I'm trying to copy the files onto my fresh Windows partition, but I'm unable to copy files that I obtained within my previous Windows installation from zip archives created on Macs.

When I try to copy those previously-extracted files, I get an error saying that I need permission from S-1-5-21-...-1000 (a bizarre long ID).

The first thing I tried was to take ownership of the files by setting my new user account as the owner, but that resulted in errors saying that I need permission from myself!

Some Googling suggested adding antivirus suggestions, so I excluded the relevant folders from Microsoft Security Essentials, but the issue persists.

For what it's worth, it seems that some program (so far I've only installed Chrome, Microsoft Security Essentials, and the latest Windows updates) created an empty folder named 601c8c7f0e0c03f725 at the root of my external USB hard drive.

What gives?
