I have no problem creating and reading a 6 gigabyte file. # uname -rs FreeBSD 4.0-CURRENT # dd if=/dev/zero of=foo bs=1m count=6k 6144+0 records in 6144+0 records out 6442450944 bytes transferred in 573.647312 secs (11230683 bytes/sec) # ls -l total 6294536 -rw-r--r-- 1 root wheel 6442450944 Mar 6 11:48 foo # dd if=foo of=/dev/null 12582912+0 records in 12582912+0 records out 6442450944 bytes transferred in 524.834994 secs (12275193 bytes/sec) Note that "foo" is really 6 gigabytes (6*1024*1024*1024 bytes), not 6 "marketing" gigabytes (6*1000*1000*1000 or 6,000,000,000 bytes). I can't create a file larger than this because I don't have enough free disk space. Perhaps someone with more disk space can determine whether a file larger than 8 gigabytes can be created and read. -- Regards, Norman C.
