I've just had a connection drop during a wireless sync, and the only laptop in the house at the moment has no serial port... am I doomed to "Checking Disk Integrity" every time I sync until I get hold of a PC with a serial port, or is there another way of doing

ro
umount /dev/hda4
swapon /swapfile
fsck -fay /
fsck -fay /dev/hda4
swapoff /swapfile
sync

without using a serial cable?
