[comp.sys.apple] DISK 3.5 FORMAT CRASH

2QZNHONE@UKANVM.BITNET (TODD) (12/22/87)

I wrote to Info-Apple about my data disk 2 of DreamZone crashed.
I did a check for bad blocks on the disks.  The test came up with 4 bad
blocks.  I used BLOCK.WARDEN to read the blocks, all 4 said I/O error
press any key then when I pressed any key the screen was full of 00's
apparently blank blocks, the blocks were as follows:

ERROR : BLOCK $04F1
        BLOCK $04F3
        BLOCK $04F5
        BLOCK $04F7

What do these blocks usually contain on a normal disk.  Would it have anything
to do with the FORMAT of the disk.  Because before this happened it was PRODOS
and now it says it is neither a DOS 3.3 or Prodos disk when using COPY II PLUS.

Any help would be appreciated.  Thanks in advance.
Could the disk just be a bad disk???   What do you think??
