Hello Gradius2 Please can you help me? I think I have the seagate drive BSY problem. I have connected up a USB to RS232/TTL interface and got as far as spin down of the motor following your instructions exactly, all seemed to go ok until the step highlighted in red, then I could not get back to level 2 and I get this cycling message LED:000000CC FAddr:0025BF67 I have noticed on another thread http://www.msfn.org/board/index.php?showtopic=128807 It is done slightly differently, instead of CTRL+Z you just press U to spin the motor up. My drive seems inaccessible now, do you know of any way to access it to give me a second chance to retrieve my data? Thanks and regards Mikul On terminal press CTRL+Z: F3 T> F3 T>/2 F3 2>Z Spin Down Complete Elapsed Time 0.147 msecs F3 2> Wait 5sec and remove the paper card, this will connect the PCB to HDA (spin motor), but since is in Spin Down state (from cmd), you'll feel nothing. Now screw just enough to make a good contact between PCB and HDA (be real careful here, don't drop the screw, just be calm, relax!). Then press CTRL+Z again F3 2>U Spin Up Complete Elapsed Time 7.457 secs (if you get this msg you did everything fine until here) F3 2>/1 F3 1>N1 F3 1>/T F3 T> <<< At this step you'll need to POWER OFF your HD for 10sec, and then POWER ON again. By power off, remove the SATA power (not PCB!). When done, press CTRL+Z. F3 T> F3 T>i4,1,22 F3 T> F3 T>m0,2,2,,,,,22 <<< This command takes a little over a minute to complete!
