Floppies aren't a good choice for long term storage. CR-R is much better. > If there is an error due to a bad sector, physical problem > with the disk, or any other factors, will the error/lost data be detected? Probably. There are checksums. Don't expect to recover the data though. > If so, how does the drive accomplish this detection? It doesn't. Floppy drives are very dumb. All the smarts are in the controller. ***************************************************************** Embed Inc, embedded system specialists in Littleton Massachusetts (978) 742-9014, http://www.embedinc.com -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.
