Problem with dd command...

[Jean-Philippe BATTU]

Hi

I am using the dd command to write data on a scsi device (/dev/st1 for
example). I am working on a linux system  with redhat distribution
7.1.94

the simple command :
dd if=/foo.tar of=/dev/st1
will fail with an error :
dd: writing to `/dev/st1': Invalid argument

Could you help me to solve this problem, and are you aware
bugs with this kind of command. The command works well
if a replace /dev/st1 by an standard unix file..

thanks for your time

Cheers !
