+slx Posted November 16, 2018 Share Posted November 16, 2018 My son accidentally overwrote his latest Action! program with an empty file. As the remainder should still be there there should be a good chance of recovering most of the data and as it's Action! a truncated file would be mostly useable. The only DD-able sector editor/utility I found on Atarimania is Disk Scanner - Double Density by Antic Software. Omnivore is good to get an overview but does not allow looking at individual sectors of an ATR without calculating the offset, V1 shows sector numbers in the directory view only. Any others recommendations? Quote Link to comment Share on other sites More sharing options...
+Nezgar Posted November 16, 2018 Share Posted November 16, 2018 The good ol SpartaDOS DiskRX, and the newer EDDY do DD, but the they're both tailored to SDFS, not sure about AtariDOS support... it will let you see and edit the raw sectors at minimum though.

1050 Posted November 16, 2018 Share Posted November 16, 2018 DiskRX that comes with SpartaDOS is DD capable as is. I would try to duplicate the disk first so that other accidents don't ruin what is there for rebuilding first, something like copymate using two drives, one as source and other as destination for the safety factor again. Hex editor would work with ATR files on the PC if this project is being done with an emulator. You don't say specifically so we can't really answer adequately at the moment. The DOS being used would be quite handy information to have here. Do not do any further writing to that disk and this should be the first thing done always. Tape over the write protect notch for example can save the day and the program on the disk. 1 Quote Link to comment Share on other sites More sharing options...
+slx Posted November 16, 2018 Author Share Posted November 16, 2018 It‘s an ATR (already backed up) with XDOS, so it should be Standard Atari DOS (2.5?) format. Directory and VTOC look ‚normal‘ and are in the usual locations. Gesendet von iPhone mit Tapatalk Quote Link to comment Share on other sites More sharing options...

Mathy Posted November 16, 2018 Share Posted November 16, 2018 Hello 1050 I would try to duplicate the disk first so that otheraccidents don't ruin what is there for rebuildingfirst, something like copymate using two drives, oneas source and other as destination for the safetyfactor again Or use MyDOS to copy the disk. "J", "1,2/N" ("Duplicate Disk", from "D1:" to "D2:" without formatting the destination disk.). If that doesn't do the trick, try "J", "1,2(1-720)/N" or "1,2/N(1-720)". (It's been a while) Sincerely Mathy 1 Quote Link to comment Share on other sites More sharing options...
+slx Posted November 16, 2018 Author Share Posted November 16, 2018 Thanks for all the hints. As this happened on an ATR, making a backup copy was easy. As my son was clever enough not to use the ATR after his mishap the new, empty file had only overwritten the first sector of the old file and a quick check with Omnivore confirmed that something looking like his missing program was on the subsequent sectors. The Antic Disk Utility was useful in tracing the sectors chain after the first one and I simply patched the directory entry to show the correct length and new starting sector. The file loaded nicely in Action! and so I copied everything to a freshly formatted ATR to save myself the work of correcting the VTOC (I probably would have patched it in 1983 to save a valuable floppy but these days it's just too easy to "make" a new one. Maybe we'll be back to preserving floppies once the stocks run out ) Watson II. Couldn't find that on both Atarimania and Google. Is that supposed to be an 8-bit utility or something from the PC? 2 Quote Link to comment Share on other sites More sharing options...

+slx Posted November 16, 2018 Author Share Posted November 16, 2018 Thanks, are there any instructions around? I could get a menu with return but am stuck at how to move between sectors and how to display the second half of a DD sector. Quote Link to comment Share on other sites More sharing options...
lemiel Posted November 17, 2018 Share Posted November 17, 2018 (edited) Didn't use it for years, so sorry, not today. Will try my best. Edited November 17, 2018 by lemiel Quote Link to comment Share on other sites More sharing options...
miker Posted November 17, 2018 Share Posted November 17, 2018 (edited) Thanks, are there any instructions around? I could get a menu with return but am stuck at how to move between sectors and how to display the second half of a DD sector. OK, so...: SHIFT + SPACE - go to next window CONTROL + SPACE - go to previous window when on sector# xxx - CONTROL + left/right arrow - previous/next, sector, CONTROL + down arrow - next sector of current file (when in FILE mode). Overall - move through HEX/ASCII/INTERN window with CONTROL+arrows Oh, and when in mem window - press CONTROL + down arrow to save current sector in memory, and CONTROL + up arrow to restore it from there. The rest should be self-explanatory Edit: only half of DD sector is displayed, so HEX/ASCII/INTERN window scrolls when you go above 128 byte.

Use a DOS diskette (or ATR), since these programs try to display the contents of a disksector at startup (and will crash or reboot if you used direct XEX loading under emulation)...
