Hello all,
I have the above drive which has funny issue.
It detect properly. Both the heads read properly till the last sectors but in patches.
It does not read initial sectors
for Example
Then it reads sectors from 119382 to 326879
It does not read 326880 to 531903
Again it reads from 531904 to 739583
Similarly these patches are repeated
Attempt to Regenerate Translator fail
Any take experts.

Thanks

seems a weak head

Both the heads read till last sector but leave fixed sector patched in between

what is the resistance for both heads in terminal?
what tools you have for imaging ?
can you image by selective head ?

Can u view the sectors 326880 to 531903 in Sector edit option ?
its all depend on which tool you are working..
If you can check heads then its lot more easy..

Using PC3K

Head test

F3 7>X

Head 00 Resistance 00D6
Head 01 Resistance 0107

Build head map
Try read each head
I think the problem is 1 head doesn't read (head 0)

Not a translator problem.
As previously said bad sectors / weak heads.

build a head map and you will find out which head is culprit.

As updated earlier it both the heads HD0 And HD1 read perfectly at 50 % location and at balance 50 % location they don't read. So i am not doubting the heads.




The non reading area is in a fixed pattern so i doubt that it can be due bad sectors .

Are you saying that you read with each head separately (the other one disabled), and reads only 50%?

Is it on the entire drive or just at the beginning?

YES



Entire drive

can you show us some screenshot of DE ?

Hello ROB,

Your problem solved ?

did u tried to image by head mapping .. u will get better idea i guess..

Screenshots showing sectors being read
Those sectors which are not read are actually read when one reads when you "Read from Active PC-3000 Utility"
That is why i am doubting in Translator
i am missing something somewhere

Sorry forget to attach the file
Here it is

Case solved
It turned out to be weak Heads. ( Funny but True )
I was not doubting heads because they were working perfectly in 50% area

thanks for update.

It looks like bad head(s).
Drive has 4096 sector size so you have build head map in Data Extractor based on logical sector size and define bad head.
