Yeah, /home/ is on the same disk. Your guess might be right because
that's what I was trying to show. When I copy the file, which is in
/home/(hda2) to /tmp/(hda1) and I sync, it takes almost 2 minutes. But
if I copy the same file, which is in /home/(hda2) to /usr/local/(hda3),
sync returns immediately. This disk isn't that old either.
hda: Maxtor 51536U3, ATA DISK drive
hda: 30015216 sectors (15368 MB) w/2048KiB Cache, CHS=1868/255/63,
UDMA(66)
