First of all I apologise for my weird "from" addr - where is that sendmail book

The original question:

Well I haven't yet found the solution. I also tried using "dd" on a small
file - the error was the same. Tar to/from raw diskettes works fine.
I also installed a 2.4 Tar jumbo patch - no help.

I suspect the (pretty primitive) AHA scsi card to be responsible. Either
that or I need to twiddle the tape parameters in (the x86 equivalent of)
st.conf. I am using an exabyte 8505.
As I'm only using the pc now & then (at home) it will take me a while
to find the solution. I'll post as new summary then.

Here is a summary of replies received:

Simple: one machine is at home, the other at work!

Hmmm... This means the problem is probably the AHA driver config.

no comment.

The problem is not on the sparc side IMHO.
