The resulting files have extra bits; specifically, 64 bytes of zeros are added to the files. I don't have this problem when writing 4mm tapes. I am using cygwin 1.3.3 under Windows 2000. I also have AIT tapes that I cannot read at all. Admittedly, these tapes are a little weird. They were written with a DOS program (autonomous collection trying to conserve power) and begin with two EOFs, data, 4 EOFs, data (this wasn't my idea). I can skip files with mt, but when I try to dd I get 0+0 records in 0+0 records out If I try two or three times, I also get "Permission denied". I'm pretty sure I'm giving dd the right block size. -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Bug reporting: http://cygwin.com/bugs.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
