PC3000 SAS and seagate terminal

[lic]

Hi all.
I was working with Evans drive. PC3k was able to read modules well under EXOS 10E2400 family, but when I tried to write any module I was getting error - utility can't write module because size is different. When I tried to write module by writing sys files through terminal - I can't. Utility was doing nothing. Look like PC3K SAS can't work with seagates by terminal. So I used PC3k express to write sys file. It worked well, but it is strange for me that PC3k SAS can't do what PC3k express can.
