Hello,

This issue is the 2nd one i have in this month with the Hitachi ARM 5432A7 models, right now i'm really having a lot of headaches because of this and the Salvation Data for Hitachi is not helping me much u.u

This are the issues
-Hard drive is not being detected as usual
-By the use of Hitachi Doctor i can view up to 20% of the sectors in Hex
-P-list is appearing empty
-Few checksum errors on SA-A and SA-B

The problem i see it's that i cannot do much if i cannot read any on the P-list

The modules i have Checksum error in SA-A are
AVZN, CGDF, HLR1, HLR2, AMPM, DMP1, SDM1 Some of them are empty and some have data

The modules i have Checksum error in SA-B are
SCTH, AVZN, CGDF

Any advice will help



Regards,

Do you have a good drive to test with ?

If so start by checking if the SD tool can read the P-List of a known good ARM 5432A7 . If NOT then it's a tool bug (one more). If it can go back to your damaged drive and try to read the PSHT module (if present). That will be your P-List.

Is this after a head swap?

no, this drive is heads fine. Although my first case i though was heads at the beggining and before and after swap the same issue.

As an update i tried with a know good drive HTS547575A9E384 and i can see p-list and g-list fine. Also the program has a bug when you clear g-list it closes itself

I've had some cases of ARM Hitachi as well.

Check here :

Looks like you can't clear G-List on those ARM based drives :

viewtopic.php?f=28&t=31091

Also here, a strange case of a drive that scans only in reverse :

viewtopic.php?f=1&t=31026

On this one i figure out HEAD 0 is BAD by doing head map on DE and cloning with one head at a time (head 1 and 2 at a time as head 0 is bad)-

Do you have DDI4 or something that you can use to clone by heads ?

All i have for now is SD. Data Compass Extractor can be used for cloning by heads. But i have to make it detected from the Hitachi Doctor maybe.

Anyway, the hard drive becomes ready and p-list records are not available although, the firmware module is fine. And for the hard to get detected as well i have to select the family first and then load from hdd.

I'll try to do something to test heads and clone because right now i can only have access to a 20% of data on the drive from the beginning

If you can read/clone 20% of the data then most likely the firmware is working properly at some level. I would check if i could clone one head at a time.

If needed disable some heads on NVRAM or on RAM, if your tool allows that. If you change the head map on NVRAM you can make one of the heads act as another, so you can "switch off" a bad head.

More than likely the drive has issues properly loading the P-List in RAM once the drive hits a bad area and becomes unstable. I strongly suspect that Salvation does not know how to deal with that.

I understand,

The last thing i can do is modifying the head map so i can try to image. Right now if i try to connect from the SD Data Compass Extractor the hard drive freezes and i cannot even view one sector. i can only view by hex using the hitachi doctor.

i'll do something and i'll tell you guys, really thank you so much for the help
