Post subject:  WD with all red blocks
Hi

I have several WD (for instance WD500BEVT) that I want to repair.
No data needed.

The drives are well detected, Modules OK, heads OK, all seem OK, but I do a sector scan, all of them are red.

Is this any bad module?
If somebody can share any hint, I would appreciate it.
Thanks

The thing is that I have about 20 of these drives, all with the same symptom which is very strange.

I have tried the Slow fix, continues the same.
I have cleared G list, regen translator, etc, same problem.
Selfscan can't seem to get it solved too.
This I have only tried in 1 or 2 because of the time it takes...

@ Spildit:

I have checked with DFL WD and UDMA.

The same symptoms on both tools.
2,5" hdd's, PCB's intact.
I have tested surface on all heads (starting on the sectors of each head). All the same.

@ Einstein

I have checked heads with the option the tool provides. Am I missing anything?
All red: when I start to do a surface scan on the tool option...

Thanks

I'm trying to format it now.

Let's see what happens.

edit head map in RAM to all 0 or all 1. Soft reset, change head map back to original and try reading sectors, you just might see the difference.

1/ Check the red point is ABR error or UNC error. If it is ABR error, check carefully checksum of module 31 and 32. If it is UNC error or other error and head testing is good, maybe the module 03,04 is not compatible with other modules (maybe someone has written modules from other drive to these drives, check the FW version on module and in the drive's label).
2/ Selftest can do it. Why do you think selftest will not affect ? The selftest is passed or failed ?
