ide-tape errors filling up syslog
Hello,
I have a machine with a SONY SDX-420C tape drive.
I have backed up to the tape and retrieved data from the tape however syslog
is being filled up with following errors :

This is filling up the logs. every time the tape is being accessed screens
and screens of this fill up syslog.
Can someone tell me what to do about this ?

Richard
