problem with ST500DM002 and ST1000DL002 Seagat

[rms610]

I have hards model "ST500DM002 and ST1000DL002" that when i connect these to pc3000 only BSY is ON and CTRL+Z doesn't work in seagate utility .i wait one houre or more for ready state but unfortunately only BSY is on continous and CTRL+Z doesn't work.Too many hards from these models are brought with common problem for recovery and repair.
when i switch power off and on ST500DM002,i see almost following terminal log :

Boot 0x10M
