       Well, more than once, when I have used that file to restore files using
   a normal "zcat" command, the file disappears, just as if it was deleted.
   CHKDSK shows no problems with the DOS partition.

Which version of zcat are you using?  There is a bug in some versions of
compress/uncompress/zcat where zcat will erroneously delete its input
file on some error, where "some error" can be your typing ^C on some
versions....

On machines where I'm undertain of zcat's vintage, I'm generally
paranoid and will type "zcat < file", to make sure zcat won't be able to
delete the file, even if it tries.
