ÂY ÐAUL Â. ÍURDAUGH

ÓUPER ÖALIDATE 64/128 CAN HELP YOU TROUBLESHOOT AND REPAIR DISKS THAT HAVE BEEN INFECTED WITH ERRORS. ÓUPER ÖALIDATE 64/128 CAN LOCATE THE CORRUPT FILES SO THAT THEY CAN BE REMOVED. ÉT CAN BE USED AS A TOOL FOR MAKING REPAIRS TO VALUABLE DATA FILES THAT HAVE BEEN DAMAGED SO THAT THEY CAN BE AT LEAST PARTIALLY SALVAGED.

×HEN A DISK IS REPAIRED USING ÓUPER ÖALIDATE 64/128, YOU ARE GIVEN THE NECESSARY INFORMATION TO MAKE REPAIRS TO THE DISK. Á TRACK AND SECTOR EDITOR IS RECOMMENDED TO GET THE MAXIMUM USE FROM THIS APPLICATION.

×HEN USING ÓUPER ÖALIDATE 64/128, FIRST COPY IT TO A ÇÅÏÓ-FORMATTED WORKDISK USING EITHER ÍENU 64 OR ÍENU 128.

ÁS WITH ANY ÇÅÏÓ PROGRAM, IT MUST BE CONVERTED TO ÇÅÏÓ FORMAT AFTER COPYING. ÔO CONVERT IT, RUN THE ÃONVERT PROGRAM (WHICH IS AUTOMATICALLY COPIED ALONG WITH ÓUPER ÖALIDATE) TO CONVERT THE FILE TO A ÇÅÏÓ-EXECUTABLE FILE. ÔO USE ÓUPER ÖALIDATE 64/128, BOOT ÇÅÏÓ, PLACE THE WORK DISK IN THE DRIVE AND DOUBLE CLICK ON THE ÓÖ ÉCON. 

ÙOU WILL BE PRESENTED WITH THE ÓUPER ÖALIDATE 64/128 ÃONTROL ÐANEL, WHICH HAS THE FOLLOWING CONTROLS: 

1. ÏPEN--ÂEGINS THE ÓUPER ÖALIDATION ON THE CURRENTLY OPENED DISK
2. ÄISK--ÏPENS UP A NEW DISK.
3. ÄRIVE--ÃHANGES TO THE NEXT DRIVE.
4. ÑUIT--ÒETURNS CONTROL TO THE ÄESK ÔOP

ÁT THE TOP OF THE CONTROL PANEL IS INFORMATION USED IN THE VALIDATION PROCESS: 
ÄÒÉÖÅ--ÄRIVE LETTER (Á, Â OR Ã) AND DRIVE TYPE 
ÄÉÓË ÎÁÍÅ--ÎAME OF THE DISK TO BE CHECKED
ÔÏÔÁÌ ÆÉÌÅÓ--ÔOTAL NUMBER OF FILES ON THE DISK 
ÃÕÒÒÅÎÔ ÆÉÌÅ -- ÎUMBER OF THE FILE CURRENTLY BEING CHECKED 
ÆÉÌÅ ÎÁÍÅ--ÎAME OF EACH FILE AS IT IS CHECKED
ÆÉÌÅ ÔÙÐÅ--ÔYPE OF FILE BEING CHECKED 
ÓÔÒÕÃÔÕÒÅ--ÓTRUCTURE OF FILE BEING CHECKED

ÔHIS INFORMATION UPDATES AS THE FILES ARE BEING CHECKED. ÔHIS PROCESS WILL CONTINUE UNTIL ALL FILES HAVE BEEN VALIDATED OR UNTIL AN ERROR IS FOUND. ÔO INFORM YOU OF ANY ERRORS ENCOUNTERED IN THE VALIDATION PROCESS, THERE IS ALSO A ÓTATUS BOX.

ÉF THE PROCESS COMPLETES WITHOUT AN ERROR, THE NEW ÂÁÍ WILL BE WRITTEN TO THE DISK. ÙOU MUST THEN HIT A KEY TO RETURN TO THE START OF THE PROCESS.

×HEN AN ERROR IS FOUND WHILE VALIDATING THE DISK, THE PROCESS STOPS AND A COMPLETE ERROR REPORT IS GIVEN IN THE ÓTATUS ÂOX. ÔHERE ARE SEVEN BASIC ERRORS THAT CAN OCCUR:

1. ÄÉÓË ÃÁÎÎÏÔ ÂÅ ÏÐÅÎÅÄ.  ÔHE DISK DRIVE CANNOT READ IN THE INFORMATION FROM THE ÂÁÍ AND ÄIRECTORY HEADER. ÕSUALLY AN IRREPARABLE ERROR.

2. ÂÏÒÄÅÒ ÄÉÒÅÃÔÏÒÙ ÐÁÇÅ ÉÓ ÂÁÄ. ÉF YOU HAD FILES ON THE DESKÔOP BORDER, THEY ARE MOST LIKELY LOST AT THIS POINT. ÔHIS ERROR WILL HAVE TO BE REPAIRED BEFORE THE DISK CAN BE USED AGAIN. ÔO REPAIR IT, YOU MUST USE A TRACK AND SECTOR EDITOR TO READ IN THE DIRECTORY HEADER, LOCATED AT TRACK 18 SECTOR 0 ON A 1541, OR TRACK 40, SECTOR 0 ON A 1581.

ÔHE ÇÅÏÓ ÉÄ STRING ("ÇÅÏÓ FORMAT Ö1.2", WHICH IS LOCATED AT POSITIONS 171-189 IN THE DIRECTORY HEADER) MUST BE OVERWRITTEN WITH ZEROES. ÁFTER CLEARING OUT THE ÉÄ STRING, RETURN TO THE DESKÔOP AND THEN CONVERT IT BACK TO A ÇÅÏÓ DISK.

3. ÅÒÒÏÒ ÒÅÁÄÉÎÇ ÄÉÒÅÃÔÏÒÙ ÐÁÇÅ #. ÔHIS IS A MAJOR PROBLEM, BECAUSE ANY FILES ON THE DIRECTORY PAGE THAT HAD GONE BAD, AND ANY DIRECTORY PAGES AFTER THE BAD PAGE ARE NOW LOST. ÔO MAKE THE DISK USABLE AGAIN MAKE A NOTE OF THE "ÐREV ÔRACK AND ÐREV ÓECTOR" SUPPLIED BY ÓUPER ÖALIDATE 64/128. ×ITH A TRACK AND SECTOR EDITOR GO TO THE TRACK AND SECTOR YOU JUST MADE NOTE OF AND CHANGE THE FIRST TWO BYTES OF THE BLOCK TO $00,$FF. ÔHIS WILL END THE DIRECTORY AT THIS PAGE, ALLOWING YOU TO SAVE ALL FILES BEFORE THE BAD PAGE.

4. ÆÉÌÅÓ ÈÅÁÄÅÒ ÂÌÏÃË ÉÓ ÂÁÄ. ÉF THE FILE THAT HAD THIS ERROR IS AN APPLICATION OR DESK ACCESSORY, AND YOU HAVE OTHER COPIES OF THAT FILE, JUST DELETE THE FILE FROM THE DISK AND RUN IT THROUGH ÓUPER ÖALIDATE AGAIN.

ÉF IT IS AN IMPORTANT DATA FILE THAT MUST BE SAVED, YOU CAN SAVE IT BY USING A HEADER BLOCK FROM ANOTHER DATA FILE OF THE SAME TYPE. ÅXAMPLE: ÉF YOU HAD A ÇEOÃALC FILE THAT HAD A BAD HEADER BLOCK, YOU COULD CREATE AN EMPTY FILE AND THEN LINK UP THE HEADER BLOCK FROM THE EMPTY FILE TO THE ONE WITH THE BAD HEADER BLOCK.

5. ÆÉÌÅÓ ÉÎÄÅØ ÒÅÃ ÉÓ ÂÁÄ. ×HEN THIS ERROR OCCURS TO A ÖÌÉÒ FILE, THE FILE IS LOST. ÄELETE IT AND RUN THE DISK THROUGH THE ÓUPER ÖALIDATE PROCESS AGAIN.

6. ÆÉÌÅÓ ÖÌÉÒ ÒÅÃ ÉÓ ÂÁÄ. ÉF THIS ERROR OCCURS ON A NON-DATA FILE, SUCH AS AN APPLICATION, THE FILE IS LOST. ÄELETE IT AND USE ÓUPER ÖALIDATE 64/128 ON THE DISK AGAIN. ÉF IT OCCURS ON A DATA FILE, THE FILE CAN BE PARTIALLY RECOVERED. ÍAKE A NOTE OF THE "ÐREV ÔRACK AND ÐREV ÓECTOR" FROM THE STATUS BOX WHEN THE ERROR WAS DETECTED. ÇO TO THIS BLOCK AND CHANGE THE THE FIRST 2 BYTES TO $00 $FF. ÔHIS WILL CUT OFF THE ERROR AND ALLOW YOU TO SAVE THE REMAINING DATA.

ÎOTE THAT IF NO PREVIOUS TRACK AND SECTOR WAS GIVEN, THEN THE ENTIRE ÖÌÉÒ RECORD WAS BAD. ÙOU WILL NEED TO GO THE THE ÉNDEX BLOCK AND LOOK FOR A RECORD THAT STARTS AT THE TRACK AND SECTOR GIVEN IN THE ÓTATUS BLOCK AT THE TIME OF THE ERROR. ÓET THIS RECORD POINTER TO $00 $FF.

7. ÔÈÉÓ ÆÉÌÅ ÉÓ ÃÏÒÒÕÐÔ. ÔHIS ERROR OCCURS WHEN A SEQUENTIAL FILE HAS AN ERROR. ÉF IT IS A DATA FILE, IT CAN BE PARTIALLY SAVED BY MAKING A NOTE OF THE INFORMATION DISPLAYED IN THE ÐREV ÔRACK AND ÐREV ÓECTOR BOXES AND GOING TO THAT BLOCK AND SETTING THE FIRST 2 BYTES TO $00 AND $FF. ÔHIS WILL ELIMINATE THE ERROR OFF AND YOU CAN NOW SAVE THE REMAINDER OF THE FILE


ÔHE EXCEPTION TO THESE RULES ARE WHEN THE ERROR IS A BAD ÂÁÍ. ÙOU SHOULD THEN COPY THE FILE THAT HAD THE ERROR TO ANOTHER DISK, DELETE IT FROM THE FIRST DISK AND THEN ÓUPER ÖALIDATE THE DISK AGAIN. ÔHEN CHECK THE FILE YOU JUST COPIED TO SEE IF IT HAD BEEN CORRUPTED. ÙOU CAN THEN COPY THE FILE BACK TO THE ORIGINAL DISK IF YOU WISH.
