I seem to be collecting more and more portable hard drives as time goes by. I noticed however that some media players will only read external/portable hard drives if they're in FAT32 format. Which means your small USB memory sticks will run fine, but most external hard drives which seem to come default as the standard NTFS format, will not play on many media players. So if you're wondering how to format an external hard drive as FAT32, so your PS3, or media player (connected to your plasma/LCD for example) can actually read the contents, this program should help out: http://www.ridgecrop.demon.co.uk/index.htm?guiformat.htm - It's s a single .exe file which allows you to format drives in FAT32 format. Quick format option is fine. Takes a minute. VT results are all clean. Limitations of using the FAT32 file system, is single file sizes must not exceed 4GB. Most avi files etc seem to be under 1GB, so no problem. Positives are that FAT32 can be read on Apple operating systems as well.
