I’m using the following syntax on a HP-UX 11.23 Itanium server:

tcpdump -w /tmp/sanG.trace -s 1500 -n -i lan8 host x.x.x.x (there is an actual IP here)

When I try to read the file using wireshark, I get the following error:

The file "C:\Documents and Settings\eazuj6m\Desktop\sanG.trace" could not be opened: Uncompression error: buffer error

Do you still have the file in /tmp/sanG.trace on the HP-UX machine?

If so, what does "file /tmp/sanG.trace" print?

If it doesn't print anything about it being compressed, copy the file from the Windows machine to the HP-UX machine, and compare it with "/ tmp/sanG.trace" with the "cmp" command; if they're not equal, something got damaged when you copied it. (How did you copy it from the HP-UX machine to the Windows machine? If you used FTP, and you didn't FTP it in binary mode, it *definitely* got damaged, and there's no way to undo the damage.)
