Thanks Susan. i use UltraEdit which would allow that. You just explained something for me. I kept recreating the file with a block sie that would work, but when I copied that data back in, it would revert. That is because the block size is contained in the data.

Sent by: u2-users-boun...@listserver.u2ug.org Charles, What I have done in similar situations is stop UniData, open the file in a hex editor (there are free hex editors on the web - Cygnus has always worked well for me), and trim back the last block (in your case, the last 1024 bytes), since that block has been damaged. Then change the modulo in the first block of the file to what your file would then be, which is 337 (which is hex 0151, so the first 2 bytes of the file would become 5101, since UniData stores the modulo in reverse order). At that point, you should be able to start UniData, run guide on the file, do a fixfile for any damage, resize it (so that things will hash properly, which might not be true with the modulo you replaced), and then compare the file to your most recent backup and any audit logs that you have for data added/changed since that backup to help you find any records that might have been chopped off at the end of the file. Not fun, but it should work... Susan Lynch F. W.

We had some file corruption last night and I am trying to recover a file. The file was so badly corrupted this morning that it wasn't recognized as a Unidata file. What I have tried is copying the data and dictionary to SAVE files at the system level. Then I did a DELETE.FILE of the file and then a CREATE.FILE STRUCTURE-HEADER_MA 13,1. Then I copied the data and dictionary files back over the originals. The dictionary portion is OK, but I get the message "File size (5538816) is not a multiple of block size(16384)." I had hoped that recreating the file with a block size of 1 would have made this work since 5538816 is divisible by 1024. But it did not work. It still thinks the block size is 16. Can anyone tell me how to recover this data?
