Re: HP Colorado 5GB internal, Red Hat 7.1, tape read problems
I read somewhere somebody suggesting to use the scsi emulation instead of native IDE tape driver.
I have no idea of how to implement this, however I guess you have to load the following drivers :
ide-scsi.o
sg.o (scsi generic)
st.o (scsi tape)
Somewhere in your /etc/modules.conf, you may have to add :
alias scsi_hostadapter ide-scsi
then you should normally be able to access your Colorado tape using /dev/st0.
Good luck.

Re: HP Colorado 5GB internal, Red Hat 7.1, tape read problems
What is the firmware revision of the Tape Drive? If it is not 2.08, you should upgrade the firmware of the drive. This version of the firmware corrects several issues that can occur over time which directly affect the drives ability to read.
Allen.
