I did an "ls". The floppy had files on it, including subdirectories. The diskette was write protected. After "cd /mnt/fd" I tried "rm *" which failed, as expected. Then, I ejected the floppy (*without* unmounting), write-enabled the floppy, then put it back in the drive. I then typed "rm *" again. The machine hung solid - no messages on console, capslock/numlock on console didn't work, ctrl-alt-del on console didn't work. I do not think the floppy activity light came on when I did the 2nd "rm *", but I'm not entirely certain. (I realize ejecting the mounted floppy was a mistake, but the system's response was less than optimal :-) Here's some machine info: Aug 5 03:33:31 bsd /kernel: FreeBSD 3.2-RELEASE #2: Sat Jul 24 01:39:21 PDT 1999 Aug 5 03:33:31 bsd /kernel: wtw@bsd:/usr/src/sys/compile/ROUTER Aug 5 03:33:31 bsd /kernel: Timecounter "i8254" frequency 1193182 Hz Aug 5 03:33:31 bsd /kernel: Timecounter "TSC" frequency 99474228 Hz Aug 5 03:33:31 bsd /kernel: CPU: Pentium/P54C (99.47-MHz 586-class CPU) Aug 5 03:33:31 bsd /kernel: Origin = "GenuineIntel" Id = 0x525 Stepping=5 Aug 5 03:33:31 bsd /kernel: Features=0x1bf<FPU,VME,DE,PSE,TSC,MSR,MCE,CX8> Aug 5 03:33:31 bsd /kernel: real memory = 50331648 (49152K bytes) Aug 5 03:33:31 bsd /kernel: avail memory = 46243840 (45160K bytes) Aug 5 03:33:31 bsd /kernel: Preloaded elf kernel "kernel" at 0xc02af000.
