I've just got a 500Gb external hard drive to use as backup on my PCs. I've formatted it as FAT32 because I want to use it on my Windows 2000 system as well as on my Windows 98SE system. When I come to copy directories from my Windows 2000 system onto the drive it's OK until I get to a 22.4Gb one and the system stops with "Cannot copy capture: There is not enough free disk space". There is 464Gb free space on the external drive, 107GB free on the drive I'm copying from (D:) and 83.6Gb on my C: drive. What's going on and how can I fix it?
