I have been using pcfs mounted floppies for almost all my installation, the other being modem transfer. So far, I have had absolute success with moving files from DOS formatted floppies to my wd0 hard disk, using pcfs with a mount point on the wd0 drive. Well, I have a second (wd1) drive, which I use for my own personal disk space (as opposed to system stuff). I wanted something off of a floppy, so I did the usual su, mount -t pcfs /dev/fd0a /floppy, and then cp /floppy/* /users/ where /users is the wd1 partition. This works normally if you substitute /users/ for /usr/, which is the wd0 partition. BUT, the file transfer stars, goes about a megabyte or so (cache length?) and then "NNGNGNNGNG!" My disk starts making this horrific sound, and I have to do a hard reset. I thought, "Damn, my disk is screwed." Well, I have done all kinds of I/O from wd0 to wd1, to see if I can repeat the problem with wd1, but it appears to be fine. My question: Is there some bug where copying from /dev/fd0a through a mount point on wd0a to wd1c screws up? I have tried different floppys, and I get the same results. Is it caching 1MB or so, and then not able to find where to continue after it dumps it? I'm curious This is not imperative, since I have no problem moving stuff to wd0 and then to wd1, if I need to. It's just kind of wierd. Also, my setup: Dell i486/50 using SYSCONS driver wd0 => Western Digital Caviar 2340 (340MB IDE) wd1 => " " " 2170 (170MB IDE) Thanks.
