Hi to all,

Have this case that the disk dont spin and it dont have any ATA register.

Change the PCB with a equal one but with different PCB numbers and i can get ID and serial.

When i try to copy any sector with DE, i have a ECC reading error ?

Anyone knows which number is the TVS or FUSE , to repair the patient PCB.


Thanks

zebong u are not forgetting someting.. like NVRAM?

Regards

Yes i know that, but what i notice in this was:

- when i change the PCB i could get ID, and read the modules !!!

is this possible without change the NvRam, normaly when i change PCB and dont change the nvram i can not get ID i have to change also Nvram.


Waiting for any comment if someone happen this.


Regards

if nv ram is not compatible i think disk goes into safe mode so therefore modules can be read. Swap NV Ram or try to rebuild NV RAM using UDMA.

Yes, as long as heads are good you can access SA, even with wrong NV-RAM. That's how Ace and SD rebuilt NV-RAM simply by rebuilding from SA. Run dynamic repair and you should be able to access data area. In some cases you have to set LBA too.

I am not facing with PLAT drives every day, but don't they store SA location in the NVRAM, as their other brothers do?
If so, it is not that probable that u can access the SA with a different NVRAM unless u set SA location before...

Pepe is right, PLAT stores the beginning of the SA location in the NVRAM. Not sure if SA location changes allot on the same model drive. I just did a PLAT yesterday and I was able to access SA with donor PCB, but the donor was from the same Raid 0 set and was 100% compatible and within 8 weeks of manufacturing date. Either way with PC3K UMDA or SD tool you should be able to easily repair this one

Then it seems PLAT do not change SA location that much

Sir Pepe,

I did WD2500JB last week also from Lacie RAID0 both drives where identical and had the same day of manufacturing and even the serial number was close. The rom was 100% compatible. It would be interesting to know how frequently adaptive information changes for the manufacturers. I know this probably changes often, but it would be interesting to know.

yes.... it would be interesting to see if MHAs are interchangeable...
