I had a disk on a NeXT develop a bad spot in it's shared C library. Really frustrating, because the programs which you would use to do a restore from backup were all dynamically linked. Booting from the CD on the NeXT doesn't work like you'd hope, because the read-only applies to all mounts below it also (sigh). On the other hand, it would be easier to recover from this problem on a FreeBSD system than it was on the NeXT (it's easier to run from the CD).
