Why can't I read a HP DAT with a SONY?

Why can't I read a HP DAT with a SONY?

I use a SONY SDT-S5000 4mm DAT (DDS2). I can write and read DDS & DDS2 tape
without any problem. Now a friend made a copy of a few file to his HP
SureStore 2000i(only DDS tape). He used tar to do this.
My Sony can't read this tape. Access to the drive is no problem but tar
reports an I/O error.
So is not every DDS tape compatible with an other DDS tape or is there only
a trick to know?

THe problem is probably that the HP drive compressed the data (by
default).

And your drive is not able to read these compressed data.

Hope this gives hints :-)

1. DAT TAPE DRIVES: Wangtek can't read HP DAT tapes

I have both:
WANGTEK   Model: 6130-HS           Rev: 4G16
HP        Model: C1533A            Rev: 9503

Neither unit can read tapes created by the other machine. Is there a way
to create tapes that can be read by both machines?

I use a program called TAPEDISK in DOS and Windows. Tapes created on
either machine are readable by the other.

BTW, is there a program similar to DOS TAPEDISK in the UNIX world?
TAPEDISK makes a tape drive appear to be one large harddisk.
