Oh, and, the problem is serious for me because I am trying to do some work on large video files.. And it's not very practical to have to ask people to split up files etc. >How-To-Repeat: Create a NTFS filesystem (on probably any disk), copy a file that is larger than 659393536 to it with an OS that has better NTFS support than FreeBSD (like Windows!). Then mount said filesystem with FreeBSD, -stable or -current, try to copy the file to a local filesystem. The copy will stop at 659393536 bytes. >Fix: N/A I talked to tjr@ about it, and he suggested trying http://people.freebsd.org/~tjr/ntfs-read-big.diff, but it has no effect on the problem I mention here. Sigh. >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
