Hello guys,

I have got the following drive: HDT721032SLA360 (320GB SATA) which stays on BSY state while turning it on.
By puting any other NV-RAM on the original board the drive become to ready state but with out recognization.
I succeed to restore the native NV-RAM of the drive by using NV-RAM Adjustment (SA search) feature.
With the restored NV-RAM the drive still stays on BSY state (I matched the version of the USAG module with the NV-RAM).
With writing the following NV-RAM_Adapted_For_Chk.nvr file to the NV-RAM chip I get access to the SA and all the modules of the drive.
I lack of ideas how to solve this drive.
Any recomandations?

I attached the SA structer test report to this message.

Best Regards,

Hi,

I had such problems, and normally related to PSHT.

The module seems to be ok (copy 0, copy 1, copy F).
But by tries to read the P-list (PSHT module) give the following:
Test : Viewing P-List
Reading defect list...
Error requesting defect list (PList)

I still use NV-RAM_Adapted_For_Chk.nvr as a NV-RAM (otherwise the drive stays on BSY state).
Any ideas how to procceed from here?

Many thanks!

Compare PSHT's and try to write them.

They are the same all over the copies.
I have a filing the the list is empty (not sure).

But PSHT should not be empty.

correct. This is why I attached the p-list module.
There is a data inside but I am not sure if it is consider as empty or not.

I don't think that data is correct.

I compared the module to the structure of 500GB hitachi drive and it looks almost the same with few little changes..
So the module might be ok

Check with a good drive if you can open and view PSHT.

I agree, probably is some issue with defect list. If module is unreadable it is possible to modify its position in USAG. Also is possible to relocate entire SA to other surface if surface has reading errors, and even hotswap can be done on SLA model.

Can you post here all copies of PSHT ?
