DLT Drive for FreeBSD 4.8 STABLE

[James Ainslie]

Hello,

I need some recommendations for a DLT drive for use with 
FreeBSD 4.8 STABLE. 

	dmesg(8) output attched.

We are using a COMPAQ SuperDLT1 4B4B Removable Sequential Access
SCSI-2 device, which is causing no end of problems. And we want to buy
something that works well with FreeBSD.

I have trawled the archives and the handbook and these deal mostly with
problems with specific drives rather than recommendations.

James.
