I backed up my hard disk some time ago, to 3.5 disks using Apple Backup 1.1A(I don't like image backup programs). Backup // is pretty smart, before it will continue backing up, it verifies the diskette that everything is alright. FINE! Then my hard disk(Profile) decied that it wanted to screw up (rather Proterm after it crashed once and I restarted from the monitor). So I copied all the newest files, then Zapped the hard disk with a utility that Zeros every block out. No problem. Now over the last week or so I've been busy doing other things, so the hard disk was left alone. Today I decided I wanted to restore it. It seems that the first 3.5 has developed some errors(about 4 blocks as confimred by Copy 2 Plus). Seems that Backup // cannot handle bad sectors, it declares an I/O error and aborts. The problem? I can't restore my hard disk. Equipment : Apple //e enhanced Unidisk 3.5 Apple Backup // v1.1A(as modifed by Morgan Davis to handle 3.5 disks). Profile 5mb. Help required: If anyone has any ideas, please post them to the net, or get me in Email. Even if you know(MORGAN) how Backup // stores the information on the disk, I may be able to get it out manualy(though I would perfer it to easier than that). Help, suggestions, soloutions will be greatly appreciated!

Ok all of you apple guru's out there, I need help! I have a apple //c, with a unidisk 3.5, 1200bps modem, and a printer. I wrote this ml program in an attempt to get my unidisk to eject a disk. when I execute it nothing happens, but if I change the command number in line 1020 to a FF, there is a message saying 'An error has occured: 01' <- bad command number. this was written using S. C. Macro assembler. The equates file has equates for cout, crout, prbyte, etc. print is a subroutine that prints out the ascii that is pointed to by the return address on the stack until it encounters a character with the hi-bit cleared, then it prints the last character with the high bit set, updates the stack, and returns. -----------------------------------< Cut Here >------------------------ 0000 .or $2000 0001 .in /ram/equates 0002 zpagelo .eq $f9 0003 zpagehi .eq $fa 1000 start jsr locate 1001 bcs error 1010 jsr dispatch 1020 .hs 04 1030 .da plist 1040 bcs error 1050 rts 1060 error pha 1065 jsr print 1070 .at -"An error has occured: " 1080 pla 1090 jsr prbyte 1100 rts 1110 *-------------------------------- 1120 dispatch .eq * 1130 jmp (zpagelo) 1140 *-------------------------------- 1150 plist .hs 03 ;parameter count 1160 .hs 01 ;device number 1170 .da ctrllst ;address of the control list 1180 .hs 04 1190 *-------------------------------- 1200 ctrllst .eq * 1210 .hs 00 1220 *-------------------------------- 5000 locate lda #$c7 5010 sta zpagehi 5020 lda #0 5030 sta zpagelo 5040 ldx #7 5050 .1 ldy #7 5060 .2 lda (zpagelo),y 5070 cmp sigtab,y 5080 beq .3 5090 dec zpagehi 5100 dex 5110 bne .1 5120 sec 5130 rts ;not found 5140 .3 dey 5145 dey 5150 bpl .2 5160 .4 lda #$ff 5170 sta zpagelo 5180 ldy #0 5190 lda (zpagelo),y 5200 clc 5210 adc #3 5220 sta zpagelo 5230 clc 5240 rts 5250 sigtab .hs ff.20.ff.00 5251 .hs ff.03.ff.00 9999 .in /ram/super.print.sbr -----------------------------------< Cut Here >------------------------ ------------------------------------------------------------------------------ | Mark Litscher | "Ahead warp zillion!" | | barak@lakesys.COM | "Ack phbbbt!" | ------------------------------------------------------------------------------

Help! I have an Xcomp hard disk that has started to refuse to format. I have swapped out drives, internal SVA cards, "interface" cards and data compresion cards all with the same result! Even the backup copy of the formatter program produces the same "Can't write Grey Marks" error. Does anyone know of this system? Anyone got a Apple Pascal DECOMPILER? The company has gone out of business and was kind enought to NOT include the source text so I am very stumped as to what is wrong and cannot set up a continous loop to locate the part(s) that failing. Can anyone help me?? Thankx

ANYONE:
I am working on a rather simple, easy program. However, this being my
first try, I am having problems! Right now, the most troubling thing is my
GS/OS LOAD segment. I can't get the sucker to load a file! AHHHG!
Please, if you have source code that will help, or have more questions
to me, send me e-mail! Either on the net, or (preferribly) via e-mail. Thanks
for anyone who helps!

ARGH! A directory on my hard drive has failed and I really don't want to have t o redo the entire drive. Does anyone know of how to use Block Warden to fix a d irectory, or maybe some other way? I used Mr. fixit, but it ships over it sayin g Directory Too Large. HELP!

The first thing you need to do is a backup using something that backs the
volume on a block by block method, like Prosel's backup. It would be
preferable to also backup those blocks that are marked as unused in the
bitmap. The next thing you will need is a copy of the Prodos Technical
Reference manual and/or Beneath Apple Prodos so you can figure out the
directory and subdirectory file layouts. Then you just go through the files
(using block warden's follow command, looking to see if the information in the
file is in the right place and either restore or makeup the information that
should go there. You basically rebuild the directory by hand. Subdirectories
also show the location they are stored in their parent directory, so you will
have to make sure the pointers for a directory point to the correct place in
their parent directory. Which directory was it that crashed? A normal
directory or one that you created? Did it have a bunch of files in it? Are
the lost files really required? If the files can be deleted, you can use a
documented method of removing entries from directories, then let Mr Fixit fix
the bit map to show the correct blocks used. This will of course require all
the other files to be in good shape, or it may make a bad situation worse?
Above all else, extreme care and patience will be required.
If you would like help, some of us here do disk recoveries for varying fees
ranging from free to a few hundred dollars depending on the kind of day we'e
had. Fortunatly, we usually have pretty good days.

Are you ***SURE***!!! your know what /volume/file.name the software is trying to write to (often enough error messages misrepresent the actual problem)? Have you tried downloading with something else? What transfer protocol are you using (XModem or XModem/CRC are HARD to foul up, but recent posts to this board indicate the ZModem can run into difficulties, and while YModem ought to be as trouble free as XModem, when in doubt, try an older protocol)? It CAN'T be the modem; it's unlikely to be the cable; if you haven't any problem uploading and reading mail, the serial card doesn't appear to be at fault. The most likely explanation is the software is trying to write to a /VOLUME/ that isn't present. /s Murph <Sewall%UConnVM.BITNET@CUNYVM.CUNY.Edu> [Internet] or ...{psuvax1 or mcvax}!uconnvm.bitnet!sewall [UUCP] + Standard disclaimer applies ("The opinions expressed are my own" etc.)
