we have a topic about PCB swaping rules. But the gurus are reluctant to share this information , or simply dont know. Sry m8.
Here's a rule for pcb swapping. (For drives made in the last five years - all manufacturers - maybe except some Samsung)
There is about +95% chance that pcb swap will NOT work.
This applies to Seagate, Toshiba, Hitachi, Fujitsu,(maybe some MHV will work), Maxtor,
WD(In few cases drive will ID, but not work properly)I don't know why all IT techicians still insist on trying pcb swap for most problems.
In almost all cases circuit board or PCB is unique for drive -
so PCB swap can be declared VERY POOR OPTION to get faulty drive working.
Please USE THIS RULE - but many will ignore in hope that it can work,
those who know don't even bother with pcb swap.
1st, DR scene is not about recovering drives made in the last 5 years. Its about recovering drives. Ppl come into the DR companys with old drives just as often as with new drives.
2nd I wonder where did u get the 95 percent figure ? From ur own PCB swaping cases ? Thats unfortunate.
Now i am not talking about PCB swap as a magical cure for all the HDD problems. But in combination with PC3000 ,
(de)soldering station , a microscope and a good pair of hands a donor PCB can do wonders.
PS i am not claming to be the owner of said good pair of hands , but i do work with someone who has em.
