I have a 500GB Toshiba USB portable hard drive (FAT32) and I often work with very big files. However, I can't transfer ANY file over ca. 4GB to my portable hard drive (it works the other way around though) because it errors out. When I try to extract a big file to my hard drive, I get the "inappropriate ioctl for device" error. So, I have to constantly use Split&Concat which takes up a lot of time. Is there any way to fix that?
 
4 GB is the FAT32 size limit.

If you only connect to Macs, reformat to HFS+ (Mac OS Extended). If you connect to only one or 2 regular Windows machines you can download software to read the HFS+ format on them.

I have a portable hard drive with a 32 GB FAT32 partition, the other partition HFS+, to give the best of both.
