So I guess restore >can not do it. It can guess as high as 32KB, but no higher. Changing HIGHDENSITYTREC to 64 would cause dump to write in 64KB blocks for most devices and cause restore to guess as large as 64KB. But, I think that some QIC tape devices will fail because 64KB blocks are illegal in some modes. I find that 32KB works for me for all drive types that I use (QIC old and new, Exabyte 8200 thru 8505). Any reason why you don't use 32KB? Stephen.
