When I execute "disk init" on a raw partition, sybase raises an error:"kernel basis_dsizecheck: attempt to write page 102399 on device '/dev/raw/raw1' failed, system error is: invalid argument".

The "/dev/hdb1" is fdisked with a type of "60"(unknown). ----- It's also tried and faied to fdisk "/dev/hdb1" with a type of "83"(linux).

# raw /dev/raw/raw1 /dev/hdb1
# raw -qa ---checked correctly
# chmod -R 777 /dev/raw

In addition, the "disk init" requires much less capacity from "/dev/raw/raw1" than that it has.

What else should I do?

Any advice will be appreciated.
