Help! (please).  I've been trying to archive my files to data cartridges and
have been unsuccessful to date.  Any experts out there?  If so, please read
on... I can use the help.

I've got a 6051 device on which to archive my files using 1/4" tape.  The
actual cartridge I've got is the following:
	3M DC300XL/P data cartridge, 450 feet (137,2m), 6400 to 10,000 ftpi,
	310 oersted tape.

Here's what I've tried.

	1.) Just saying "tar -cv dirname".  Things look good until I try to
		read it back ("tar -tv"), then I get some sort of blocking
		error.

		Q1: Can I somehow recover this data?

	2.) Tried saying "tar -cv -b20 -s450@2400 dirname".  Things looked good
		until I got along in the directory, then I get a message telling
		me that I've run off the end of the tape.  I was told that 
		this particular cartridge can hold 45Meg, but the process never
		even got close to that.

		Q2: I know that the tape is 450 ft long, so at least the
			"450" in "-s450@2400" is correct.  Can I specify a
			higher density figure than "2400".  How do I know
			what to use?  Can't seem to get any info on this.

		Q3: What does ftpi mean, feet per inch.  Is this some sort of
			specification on how quickly that sucker can spin?

		Q4: Any advice on whether I should place the cartridge in the
			6051 cold or let it warm up for a time.  The thing 
			gets real hot (can't even touch the metal plate on the
			bottom) if it sits in there for a while.  Is this 
			normal, or is my 6051 flaking out?

Could sure use some help on this.  Please e-mail direct and I'll post the
results if there's interest, thanks.
