If you consider it useful and continue to keep a copy of it please register it with the author. There is a fee of �5 for registration, which goes to Comic Relief. See the end of this file for instructions. You may distribute this freely, as long as *all* files (except "Options") are left unchanged. I have attempted to test this program to the best of my abilities and facilities, but: I CANNOT BE HELD RESPONSIBLE FOR ANY DAMAGE WHICH MAY BE CAUSED BY THE USE OF THIS PROGRAM. Having said that, it has been tested on ADFS (hard and floppy), Oak SCSI, Morley SCSI, and I am reasonably confident that it will work on IDE drives, as long as the SWIs are sensibly named. This program is independent of SWI numbers for filing systems, but is dependent on SWI names, in particular, SCSI systems must prefix their SWIs with "SCSI_" or "SCSIFS_" and IDE systems must prefix their SWIs with "IDEFS_". If anyone has an IDE system, I would be grateful to hear about DiscMedic's successes and failures! INTRODUCTION ------------ Well, it's here, and only about 8 months late. DiscMedic is a desktop disc sector editor. It works on FileCore format discs, i.e. L, D, and E format ADFS floppies, D and E format ADFS hard-discs, and SCSI, IDE and RamFS discs. F format is not yet supported as I don't have an A5000. MS-DOS 720k format is supported at a pinch, but with a few quirks - see below for details. DiscMedic can be used to examine and repair discs, extract data from them, or just to have a good nose around. This is a preliminary release, and it will not do the following: * Undelete files * Repair maps/disc records/boot blocks However, while it won't do this automatically, if you have the necessary knowledge, you can do it by hand with DiscMedic. Future versions of DiscMedic will do this automatically, as well as providing numerous precautionary measures to prevent your beloved data taking a trip to Disasterville, Arizona. You will receive an update of these if you are registered, and if you provide a blank disc + p&p (I'm not getting paid for this you see!) for the purpose. To start DiscMedic, double click as usual on the filer application, and you will be rewarded with a reet lovely icon sitting on your bar. HOW TO USE IT ------------- This application is fairly self-explanatory - you can probably guess most of the functions by playing. Let's face it, you're not going to read this manual are you? I'm wasting me time. However, due to the fault-tolerant nature (well, almost) of this program, there are a few quirks which may need explanation. The Main window --------------- Click select on the icon to display the main window. You will see various icons which display the current disc parameters - drive, track, head and sector. These icons are linked to the disc address icon, so if you adjust the parameters, the address follows, and vice versa. The parameters can be changed by clicking select on the arrows (adjust has the opposite effect) and will change in increments of one. The address icon will change by the size of one sector. Holding down SHIFT will multiply these increments by 10 for faster adjustment. None of these icons will let you select values that do not correspond to a position on the disc. You have probably noticed that the 'Drive' icon is bordered - clicking on it will mount the specified drive. DiscMedic only deals with one drive at a time, and does not auto-mount (there are exceptions - see 'Options' below). This should be borne in mind, especially with removable media. Mounting the drive causes DiscMedic to examine the disc record (and boot block if a hard disc is selected). It performs a number of consistency checks, and may reject it if there are too many errors. If this is the case, it substitutes a 'safe' disc record which should let you access most of the first track of any disc, enabling you to fix the disc record. If you played with the parameters before mounting the disc you will have noticed that when no disc is mounted, this safe record is in use, and will not let you go past the first track. The Read and Write icons: Read This reads the sector from the specified drive and position. It displays it in a scrollable window beneath the main window. This is called the data window. Write This will write the data in the data window to the specified position on the specified drive. If you load data in and attempt to write it out to a different disc with a different sector size, the data will be truncated if the destination sector is smaller. If the destination is larger, only the first part of the sector will be overwritten; e.g. writing a 256 byte sector to a 1024 byte sector will overwrite the first 256 bytes and leave the remaining 768 bytes unchanged. If you write to the area of the disc which contains the disc record (boot block for hard discs, sector 0 for floppies) then the drive is automatically unmounted. In the top right of the main window is an icon which displays the current Filing System (wrt Discmedic) and the disc format, if known. SCSI, IDE and RamFS discs are always E format. Clicking on this icon will cycle through the available filing systems. The icon below this one indicates what kind of data the sector contains: 'Unknown' indicates the disc is not mounted 'Data' indicates a normal data sector 'Zone ...' indicates that the sector is part of an E format map. The superscripted number following the zone number indicates whether you are in the first or second copy of the map. 'Boot Block' indicates that the sector is part of (or possibly all of) a hard disc boot block. 'MapSector�' and 'MapSector�' indicate that the sector is part of a L/D format free space map. The Data Window --------------- This is a scrollable resizable window which displays the sector data. The grey column on the left indicates the sector offset for each row of data. The black text displays hex and ASCII versions of the sector data. Clicking select in the window will allow you to move around and edit the data. The arrow keys move the caret, and holding down control moves as far as possible in the specified direction. The keys 0-9 & A-F will enter hex values in the hex display, and printable characters will alter the ASCII display. To switch between Hex and ASCII, press the TAB key. When you change data to be different from the original, that data is displayed in red. Pressing F8 while over a changed piece of data will restore it to its original state. The behaviour of scrolling and the caret is the same as in Acorn's Edit application. The Application Menu -------------------- Clicking MENU on the icon bar icon brings up the application menu: Info - displays info about the program, including its Careware status. Options - allows you to set and save options. This is duplicated in the main menu and is explained below. Quit - I'll let you figure it out, Boo Boo. The Main Menu ------------- Clicking select in any of DiscMedic's windows brings up the main menu: +-------------+ | Save � | | Drives � | | Find � | | Checksums � | | Options � | | Misc � | +-------------+ Save ==== This submenu will save the current sector data in the usual Risc-OS drag-and-drop manner. If you have not loaded any data then a block of zero data is saved. Drives ====== This submenu presents a list of what DiscMedic believes to be available drives, in iconic form for easy selection. This menu is dynamic and tracks Filing Systems dying and starting up, so it should always be an accurate reflection of the drives available. Find ==== This leads the the following options: +-----------+ | Data | | Directory | | Map | +-----------+ Data & Directory ---------------- NB: You cannot search MS-DOS format floppy discs. (This will be possible in a future version) The first two options are very similar. They both pop up the Find dialogue box, which is used to search for data on the current disc. The writeable icon at the top labelled 'Find:' should be edited to contain the string to search for. Whether or not plain data or a directory is being searched for is selected by two radio icons. The menu options are just shorthand ways of pre-selecting these radio icons. If 'Directory' is selected, then data is searched for which represents a directory of that name on the disc. For instance, if you had a broken directory called 'Goodies' somewhere, you could click on 'Directory', type 'Goodies' into the search field and start the search. When (assuming the directory is relatively undamaged!) DiscMedic finds it you can set about repairing it. There is no guarantee in this version that such directory sectors found are in use - they may be old deleted data sectors. It is suggested that you note down the address, and continue the search until the end of the disc to determine which sector(s) to edit. Future versions of DiscMedic will scan the directory tree / disc map to find directories. To see how this feature works in use, try looking for the root directory - type '$' in the search field, select 'Directory', and click on 'Start'. The High Speed icon will cause DiscMedic to use all available memory to load data into, which can result in significant improvements in search times. This is most useful on hard discs, but will speed up floppy searches as well. The status area on the right indicates whether DiscMedic is 'Idle' or 'Searching', and the gauge gives an indication of how far the search has progressed. Clicking on 'Start' will start searching from the address specified in the 'Address' icon in the main DiscMedic window. Therefore, if you want to search the whole disc, you must set the address to 00000000 before starting. While searching, the machine will still multi-task, although with High Speed enabled it may be somewhat sluggish, ARM3 permitting. The search can be stopped by clicking on 'Stop'. You may then continue the search by clicking on 'Continue'. You can toggle the high speed search option, or change the string to search for, and then continue from where you left off. If you alter the Data/Directory icons, you _cannot_ continue the search, but must start a new one. If and when the data is found, DiscMedic will attempt to move to that position on the disc and show you the data it found (barring restrictions placed on it by the options the user has set - see below). The caret will be positioned in the ASCII segment of the data window at the start of the data found. If you click on 'Continue' and the string appears later in the same sector, the caret will simply be moved to the new position, otherwise the search will continue as normal until you interrupt it, the data is found, or the end of the disc is reached. The search may also be paused by closing the Find dialogue box. To resume the search simply select Find Data/Directory from the menu again. Map --- This will reset the address and parameter icons to point to the start of the free space map on the disc. Clicking on 'Read' (unless auto-read has been selected - see options below) will display the first sector of the disc map. Checksums ========= +------------------+ | Zone Checksum | | Zone Cross Check | | Directory | +------------------+ The first two options will be available if the disc sector pointed to by the parameter icons is part of an E-format map. The zone checksum checks the checksum byte for that sector of the zone, and corrects it if it is wrong. The zone cross check compares the cross check bytes of all the other zones in the map to ensure they are self consistent - it will also rectify the cross-check byte if it is wrong. If the sector is not part of an E-format map, then the first two options are greyed out. The 'Directory' option, on the other hand is always greyed out, as it is not yet implemented! It will appear in a future version of DiscMedic. Options ======= This submenu displays a dialogue box to set and/or save the DiscMedic options. The options are as follows: Automatic --------- Read: If set, DiscMedic will automatically read the sector data in whenever the disc address, drive, or filing system changes. Write: If set, Discmedic will automatically save the sector data to disc whenever the disc address, drive, or filing system changes. Checksum: If set, whenever DiscMedic reads in data for part of an E-format map, it will check the zone checksum and cross-check bytes and correct them if they are wrong. Warning ------- Read: If set, this will cause DiscMedic to ask for confirmation before reading new data in (for *any* reason, including the search finding the required data) over sector data which has been edited but not saved back to disc. Write: If set, DiscMedic will ask for confirmation before writing data to disc, for whatever reason. Checksum: If set, DiscMedic will ask for confirmation before correcting either the zone checksum or cross-check bytes. Sector Wrap ----------- If set, this option causes DiscMedic to alter the 'Head' parameter when the 'Sector' parameter loops back to 0, or loops from 0 back to its maximum value. Similarly the 'Track' value will change when the 'Head' value crosses either of its boundaries. This enables you to step through the disc just by altering the 'Sector' parameter. If this option is not set, then if you don't try to alter the 'Head' or 'Track' parameters, they won't change. This option is much easier to understand than it is to explain - just have a play about and you'll get the idea. Search delay ------------ This specifies the number of centiseconds that DiscMedic pauses for between each block of data it searches. It can be from 0 to 99 cs. SAVE and OK ----------- Clicking on OK will make the options take effect, whereas SAVE will make them take effect, but also save them as the default options for the next time DiscMedic is loaded. Misc ==== +--------------+ | Drive Info | | Clear Buffer | | Undo All | +--------------+ Drive Info ---------- This will display the disc record window for the currently mounted drive. If no drive is mounted, DiscMedic will attempt to mount the specified drive. The information is fairly self-explanatory - if you don't understand what any of the fields mean, then you probably don't want to know. If you want to know the *exact* number of bytes on the disc (the display rounded up to Kb, Mb or Gb - try it and see) then you'll have to load the disc record in and work it out from that. The Comic Relief faces do have a purpose! This window displays the record found on the currently mounted disc, and, if the faces are happy, then DiscMedic thinks the disc record is OK. If the faces are sad, however, DiscMedic does not think the disc record is valid, and is using its own 'safe' version of the disc record to access the disc, and access will be limited to the first track. This is enough access to fix the disc record by hand. Clear Buffer ------------ This will zero the data in the data window. Simple enough for ya? Undo All -------- This will restore the sector data to its original unedited form. Known Bugs and Featurettes ========================== When accessing a D format hard disc with a 'Bad defect list', you can read from it, but you can't *write* to it. This is a real pain and I can't figure out why - I've wasted enough time already on this. If anyone can help with this, drop me a line! Revision History ================ 0.91 First public release! 0.92 Allowed window drag by dragging with Adjust while on (almost) any part of the windows. Fixed resizing bug - when main window is beneath others and data window is resized with select it used to come to the front but the main window didn't - now it does. Still haven't fixed case where user clicks select on resize icon but doesn't change size - probably have to hang some godawful kludge off the redraw code cause wimp refuses to tell me about it otherwise *Why* doesn't bringing the window to the top with the resize icon cause a window open event??? Bugs: Auto-mount disc if find started with no disc mounted. Wimp error 'Input focus window not found' if you close window and start search. Add support for toggle size on data window Future Improvements =================== Automation of map/disc record/boot block repair and file recovery. Saving of any range of data from disc (to byte resolution) to a file. Loading of a disc file to disc address (to byte resolution). Delete-tracking. Auto-backup of disc map, and directory structure. Faster and more intelligent search. Indication of defect sectors on E-format discs. Easy editing of disc records and boot blocks. Time-travel feature to avoid disasters. Crossword-solver. Software implementation of 64 Mb of RAM. etc. etc. Closing comments ================ Well, that's about it. This program was started in May 1991 so you can see how long it takes me to get my act in gear. It was developed on an A440 with Oak SCSIFS and a Serial Port/QDE hard drive. It was coded using Acorn C v3, and then Acorn Desktop C v4, which, by the way, barring a few irritating features (are you listening DDT?), is one of the nicest development environments I've ever used. It's reasonably robust and has been used in the past (in an older version) to resurrect a very large disc drive (512Mb) which had a broken root directory, and which wasn't backed up, for a well-known BBS. Mentioning no names, but suffice it to say everything's Fiennes now. So it does have some uses! Thanks (directly and indirectly, for various reasons, and in no particular order) to: Philip Colmer (for releasing FileCore details into PD and releasing me from my non-disclosure agreement) Simon Huntingdon (for Interface) Andrew Foyle (for Acorn C) Hugo Fiennes (he gets bloody everywhere doesn't he?) All at Arcade (Ian, Lorcan, Peter, Outlaw, William, Graham, Philip, numerous Steves, Michaels and Daves, Emmet, Karen, Alan, Jick, and basically everyone else *except* Piers and Jp) Jeff Gorton (for assistance/information from Acorn) Brian Sterrett (for assistance in communication ;-) Jeremy Burton (for motivation) Music listened to while writing this program: Due to the time it's taken me, nearly all my CDs..! Queen, Genesis, Jarre, Tikaram, Collins, Gabriel, Erasure, Sam Brown, Fordham, Van Morrison, Level 42, Yazoo, PSB, Spandau Ballet, Thin Lizzy, Oldfield, Yes, etc. etc. Happy times!
