- Summary: How to fix the unreadable A2.CENTRAL.9404 file.
When I got the April issue of A2.CENTRAL on disk, I found the 250-block
file "A2.CENTRAL.9404" was not readable. I played with it for a while
with the ProDOS and GS/OS utilities I have available and couldn't do
anything useful. So next day, I called up Resource Central. They said:
1) Yes, all the disks they mailed out had this problem.
2) The corrected file will be included on the May disk.
3) In the meantime, there's a way to make the file readable.
To make the file readable, get a sector editor (I used the 3.5 bitcopy
option in Copy II Plus version 8.2) and:
1) Make a disk copy of the A2.Central original and work on the copy.
2) Read block 0002
3) Go to byte number 163 (HEX)
4) You'll see the value: 2F
5) Change this value to: 3F
6) Write back block 0002 to disk
(The bad byte "2F" is the erroneous file storage type and it comes right
before the filename. I don't know what "3F" represents - ASCII text?)
Now you can read the file (it still has some garbage characters at the
very beginning of the file) with a text editor. I used ShadowWrite 1.3.3.
This worked for me - I hope it helps someone else who does not want to wait
a month to read the April A2.CENTRAL newsletter.
