In addition, it takes the "Find Track/Sector Lists" program (FTS) of Beneath Apple DOS a step further by actually recovering lost files on a diskette automatically! Fixcat will also allow you to remove the DOS image from track 1 and 2 to provide more room for files and will recover lost sectors by correcting the VTOC freespace map. FIXCAT MESSAGES =============== Display in what slot? If you wish to have fixcat display its message only on the Apple screen, enter 0 (the default). If you want them to be printed on a printer, give the slot number of your printer here. Automatic Timeout in Seconds? Enter 0 (the default) if you want FIXCAT to always wait for your response to each question it asks. If you specify a number of seconds, in the other hand, each time FIXCAT prompts you for a response, it will wait that number if seconds before taking the default as your answer. What Format is Your Diskette? If your diskette is 16 sector format, type 16 (the default). If it is an older 13 sector diskette, type 13. Read existing catalog from diskette or start from scratch? ("R" or "S") If your catalog is at all intact, specify R (the default) to have FIXCAT use it as a basis for its operations. Only if there is not a single valid sector left in the catalog should you specify "S". In this case, FIXCAT will start with a zeroed out catalog track and will build it up from scratch. Does this diskette contain a DOS image on tracks 0, 1, and 2? If this is a standard, bootable disk, reply Y (the default). If you want to recover track 1 and 2 for your own and never boot this diskette again, reply N. Also reply N if you have previosly recovered these tracks using FIXCAT. Scan for Lost or Deleted Files? If you do not think you have any missing files, reply N (the default). If you wish to have FIXCAT search the entire diskette for "unattached" track/ sector list sectors, type Y. Recover This File? If you think that this is a file you want, reply Y (the default). If the file looks like an old deleted file you no longer wanted, reply N. What type of File is it? (T,I,A,B,R,S) If you were able to identify the file, you probably know its file type as well. If not, FIXCAT will prompt you with a pretty good guess. You'll find that FIXCAT will be correct in its guess about 95% of the time. If the wrong file type is given and you later detect this you can delete the file and rerun FIXCAT, supplying a different type this time. Apply Accumulated Corrections to the VTOC/Catalog Track? Reply Y if you want the corrections you have authorized up to this point to be applied to the catalog track on your diskette. Reply N if you want to forget the whole thing and not change your diskette after all.
