I am trying to read a Block0 driver descriptor map from old-style Apple Partition Map formatted USB thumb drives which were formatted using Mac OS Standard (HFS) on OS 9. I am using Xcode 4.2 on 10.6.8. But when I do the read the entire Block0 structure comes back filled with zeros. I've checked my device open and seek calls and they correctly set to byte offset 0 on the device. This email sent to site_archiver@lists.apple.com
