    i've got a 250Gb FAT32 formatted external hard drive, and everytime i try to copy something to it from my powerbook, it'll copy it, but when i got back to use it, it's converted it to a filetype called "Unix Executable File" and wont let me delete it. i've tried several ways (even plugging the drive into a windows machine to delete it, but it says the file cant be found)

    is this an issue with writing to FAT32 in OSX, or something else? i'm thinking i might try formatting in the Mac format (HDFS?) and see if that makes a difference

    Since Fat32 is an old mocrosoft format, you have to care about some things:

    - Filnenames are limited are limited to i think 16 signs (or maybe 8) and you may not use some specific (space for example and definetily no dots (except for extensions)) either
    - Fat32 supports only partitions to a size of 24 or 25 Gb (unless you increase the blocksize, but on my lacie<->pb connection problems occured with a partition of 80 Gb size, but with 4*20Gb Partitions it works)

    If you dont want to use the external drive on a windows machine, i recommend formatting in mac-journaled-filesystem. With that no problems should occur at all.

    i thought it was windows that only supported smaller partitions, but the actual file system supports partitions up to 2Gb. i read that on a few websites, so it could be wrong.

    i'll be sure to watch my filenames, and special characters in filenames, if that doesnt work, i'll do the 2 partitions...going to take a while copying everything over though. would windows even be able to see the mac journaled drive?

    im thinking i might just get an old 20gb laptop drive and make a little fat32 enclosure for getting things from windows, seeing as i hardly ever use it, unless i can really help it!!

    Windows will read up to 2 TB partitions of FAT32 (so will OS X). Windows can't format a partition over 32 GB though (You'll need OS X for a 3rd party Windows program for this).

    Also, you may want to consider putting the appropriate file extentions on the files you're copying (if you're not already).
