How can I let Windows XP read Mac OS Extended (Journaled) drives? How can I let another PC using Windows XP (Service Pack3) read Mac OS Extended (Journaled) volumes? Windows XP shows nothing.
Boot Camp Drivers

You can use the Boot Camp drivers which integrates HFS read/write into Explorer.

You don't need Boot Camp to download/install the drivers.

HFSExplorer

Alternatively, you can use HFSExplorer:


  HFSExplorer is an application that can read Mac-formatted hard disks and disk images.
  It can read the file systems HFS (Mac OS Standard), HFS+ (Mac OS Extended) and HFSX (Mac OS Extended with case sensitive file names).
