isolated pulses measurement of Seagate drives.

Hi all,

I would like to measure the isolated pulse of Seagate 7200.10; could you please tell me the commands for do that?

here are some commands that I think it should be.

1024k x 16 DRAM
NHAWK - 1_Disk S-41 10-23-06_16:40
HM SFI
!
(P)PATA Reset
Slave
T>/2
2>S1000
2>A0
Single trk - Hd 0
2>P1414
2>W
2>R
2>Pgm=00 Trk=01000(00F52:3D[01C2C]).0(0).000(FFF) Zn=0 Err=00 ErCt=0000 Hlth=0048 CHlth=0000 Ready LBA=005BB944

I have diff-probe measured the signal at RDX-RDY point, but cound't see that signal.

-Many Thanks & Best regard.
