try `mt status 2'. You will get an output containing the current
blocksize set by NT. It's likely set to 512 bytes which is unlikely
the blocksize used by Solaris. Set the blocksize either to the
value of the Solaris tape driver or set it to 0 which enables
variable blocksize tape I/O iff the NT tape driver for your drive
supports it. `mt status 3' gives loads of output describing the
supported features of the tape driver.
