[daip] Problem between record length and block size, with READISK

[Belles Pierre-Emmanuel]

  Hello Eric,

    The file size is not a multiple of 2880, indeed. Some of the data must
be missing. If you tell me that the tables are written at the end of the
file, then they are probably gone and my only hope is to find these tables
somewhere else, in one of the other files of my catalog.

    No, the files were written on a local directory of my former machine
and I just copied them on an external disk driver. I remember that I had to
regularly make some extra space available on the disk, because the data
were taken a lot of space and, sometimes, were filling in entirely the disk
space. This may be responsible for the truncation of some of my files.

    In any case, thank you for your help :-)

    I wish you a happy new year !
