A few questions:

1. What version of dd are you using? ('dd --version' should show the version.)

2. Does your kernel have SCSI tape support? Does it have SCSI tape support in
module form? If so, have you loaded the SCSI tape module?

3. Why are you using a beta release of RedHat rather than a real release like
7.2 or 7.3?
