Copying Export File to exFAT Drive Causes Corruption

    My upload speed to the internet is slow so I tried to copy an exported file to an exFAT formatted flash drive to upload the backup from a Mac computer with a faster internet connection. I have found that copying the export to the exFAT formatted drive somehow causes corruption to the file. When trying to import the exported file from the flash drive, I get the message that the file is corrupted. Also, when dragging and dropping the file on the flash drive to https://traktor.servmask.com, the file cannot be read (it doesn’t show the backup contents). On my Mac, the file’s thumbnail on the flash drive shows as EXEC instead of being blank as usual.

    I reformatted my flash drive to use the Mac OS Extended (Journaled) format and tried again copying the export to the flash drive. This time, the file can be read by https://traktor.servmask.com without an issue.

    Do you have any idea why copying to an exFAT formatted drive would corrupt the file? Thanks.

    It might have something to do with the driver implementation of exFAT. Looking up exFAT specs, it has support for very large files. It might be that something in the driver implementation of that filesystem is causing the corruption if the file is very large.

    It seems that copying it to an exFAT formatted drive wasn’t necessarily the cause of the corruption after all. After formatting the thumb drive as Mac OS Extended (Journaled), copying the archive to the thumb drive worked for a while but then the archives started getting corrupted again after a period of time. I just tried a different portable hard drive (of much better quality) formatted with exFAT and then uploaded the archive from that drive to https://traktor.servmask.com to test it. The file was read successfully. I’m thinking the issue was that my little 256 GB thumb drive must just be absolute garbage.

    Thanks for your time. ??
