I understood the FAT 32 answer...
... I have a western Digital external HD formatted in FAT 32. It reads quite well on my apple and windows computers.
Now, I can open and read a NTFS HD connected to my mac. I can even drag files from it onto my mac... I just can't write to it. But, I also have a Seagate FreeAgent Go that I formatted just for use on my mac. I use this for storing large projects and software to transport from school, to work, to home. When I plug it into a windows PC running XP... it won't even be recognized as a hard drive. That is why I asked... OK... what do I need to do... to get a windows PC to read an external HD formated for apple? Will it be "read only" on a PC, the way an NTFS HD is read only when plugged into a mac?
If reformatting to FAT 32 for a PC to be able to read apple produced files is the only way, then it is the only way. I will grant that I could have asked if there was a windows utility to allow a MS machine to read an apple formatted HD or that I could have been more descriptive of just what I wanted to accomplish. I may know a great deal about some complicated pieces of audio/video and graphic software but I am extremely ignorant about what makes my computer actually work. Thus, telling me that FAT32 is my only option would have been a wee bit more informative than stating "then do that" was.
