Re: [Avid-L2] Re: File Size limit on Fat32 4GB - one byte?

"Erase" reformats the existing partition but not all formats and partitions are compatible. Erase was originally intended to quickly reformat a drive with the SAME or similar format (back when we did not have so many!). It will allow you to make bad selections. It shouldn't, but it will.

Frankly, I never "Erase." I consider this a legacy function from the days of floppies. I always use Partition and I always check the boot record type (Partition, under "Options") as Disk Utility does not always set this correctly either even when creating a new partition. I use MBR (Master Boot Record) for NTFS partitions and GUID for Mac HFS+ partitions. FAT32 (aka "MS DOS") must be MBR. Modern Windows systems and NTFS are compatible with GUID but MBR is much older and compatible with pretty much everything and that is generally my goal. I would use GUID on any drive dedicated to a Windows machine.

Every camera I've dealt with so far limits file chunks to 4GB for this reason. So FAT32 is still the ideal choice "in the field."

The advantage of Paragon and Tuxera over "3G" is speed, but I've installed 3G on many, many machines and have never had a problem. I also use Paragon and it is faster. 3G sometimes has issues properly dismounting a drive. This has not caused a data problem, but simply causes the next machine to report the drive as improperly dismounted.

Disk Utility will allow Apple Partition, but this creates a bastard format that is unusable on many machines. I prefer MBR as it is the older and more widely supported and better understood partition map.

I'm experiencing this limit with a usb jump drive with 16 GB capacity trying to copy a 7.3GB QT movie. If I reformat EXFat it will copy. Okay I get this but it seems like everyone always says format cross platform media drives etc.... to Fat-32 to bounce between Macs and PCs. What happens in Avid with a media drive formatted Fat 32 and a media file in excess of 4 GB? What if I do a video mixdown to a Fat 32 of an hour show? I'm usually running Mac OS extended volumes on my Mac systems but it would seem over the years I would have hit a 4 GB road block at some point on Avid, other the the omf/aff limitations that can now be bypassed. Not having a problem but I can't believe I've never been burned by this with external drives.
