I once was successful running fsck on a FreeBSD file system using a USB-stick installation of NetBSD. This was after NetBSD crashed with unclean shutdown. But you could do this probably at least as well using a USB installation of FreeBSD, need not have fancy stuff such as X, multimedia, etc. With OS/2, and my memory dates back to the 1990s to April 2001, it was necessary to boot from installation floppies in maintenance mode to run CHKDSK /f on drive where OS/2 was installed. But some time during the single-digit days of April 2001, CHKDSK, running automatically after a crash, not due to power outage, ran amok and trashed my installation and other hard-drive partitions too. Then I was never again able to boot OS/2 Warp in any way, always got Trap 000e or Trap 000c. I have NetBSD src and pkgsrc trees on same partition used for a FreeBSD installation, and that creates a hazard with NetBSD less stable than FreeBSD. But surely it would be good to buy a UPS, as I do, so you can shutdown gracefully instead of all-of-a-sudden. Tom
