Once back in the software, you're ready to start calibration. Actually, there was a small episode here. It stands to reason that after replacing the board, TREX should be recognized as 0.00M after re-powering TREX, but after replacing the unlocking board, I found that the hard disk was still out of the disk as the board before I replaced, and after repeating it several times, it was recognized that the hard disk information should be because the position of the defined 01 module is the same, causing the hard disk to power on and self-test again according to the normal process, and the result was a bad sector in the firmware area.
Select the parameters and start running.
Check the process of the PALMER family to which this disk belongs, decompress the firmware package that comes with it, extract modules such as 10, 411, 3408 AC ERASE, 243B Mini TouchDown firmware head flight altitude adjustment, and modify the Field List, so as not to re-run the disk due to setting problems.
Replace the new unlocking pad you purchased.
When the intelligent burning process ends, bad sectors in the firmware area are displayed.
There are still a certain number of bad sectors in the firmware area, and it should not affect the loading of firmware based on experience.
After several DSA calibrations and adaptive filter calibrations, there is the 2403 head read and write power with flight altitude adjustment, the 2404 set the read and write cross factor, and set the MRJog. This family has a unique process, the Pivot Cal 0x243A, which literally translates to pivot alignment.
After waking up from a sleep, the hard disk has completed the 2420 process, that is to say, the TPI and sector density of each zone have been set, and the capacity can reach 1TB, which is basically half the success here.
After the capacity calibration, the familiar 2407 full ARCO 241E 241F PMET CC 0x2414; There is also a HOT ARCO 0x2409 to ensure channel testing. I didn't shoot all of them, but I did them perfectly.
Write the RRO test in its entirety. Due to the high density and slow rotational speed, the two heads were calibrated for about 11 hours, but there was no log recording
Once the above process is complete, it is time to scan the defects and generate the P form. After nearly 50 PST processes, the self-calibration is officially over.
Let's run a 3422 and 3423 process manually
The entire calibration process takes about 50 hours, and the final number of defects is relatively small.
Immediately after the disk is released, the information and hard disk function configuration are carried out according to the model of the original disk, and it must not be seen that it has been repaired |
