Because people do know how to remove the diode on the WD when it's shorted but people don't know how to patch the FIPS module on Samsung ROM so when it goes bad the drive doesn't spin and the so called DR guys just replace the PCB and call it a un-repairable PCB problem....
Honestly .... is this a real question ? That Marvell MCU pard doesn't make any sense (well, all the post doesn't make sense)...
Why is it so hard to decrypt a truecrypt volume on a hard drive and why is it so easy to gain access to user files locked with windows password ? After all both are on the same sort of hard drive .... if the files are stored on the same media why some of them are so easy to gain access to and the other so hard ? Same for Marvell MCU .... Get something like a Marvell MCU on a PCB with really bad protection like no fuses and no TVS, nothing .... Get the same Marvell MCU on a PCB with a good protection design like lots of protections for all power supply voltages with TVS and Fuses and NOT that junk WD design .... Guess what ... both have Marvell MCU but some when suffering from overvoltage will survive and the others don't because of the way circuit is design ...
Why some crypto IMPLEMENTATIONS do get cracked like for example WEP and other implementations are more or less solid like WPA ? It's the SAME CRYPTO what changes is the IMPLEMENTATION .....
Also are you sure you can't repair a Samsung PCB ?
Majority of DR guys will have no clue about electronic and the only thing they can do is remove diodes, bridge fuses and swap ROMs .... The few ones (most likely you) will bridge the diode , remove the fuse and toast the ROM lololololol The ones that do know how to fix the PCB are happly fixing other appliences and not doing DR lolololol With some exceptions of coure .... at least with @fzabkar exception ....
Why don't you PM @fzabkar to see if he can help you out with Samsung PCB repair ?
Did you understand my Question 1st.? if not, then you may ask for clarification instead of jumping to your own conclusions here...
I mean Repair with 3k (do you own one?)... when you write the wrong ROM by mistake the PCB dies, and there is a way to repair it (in WD using 3k)
my Question was why not Samsung PCB!!!
As for your Question to ask "fzabkar" for help, i think i posted before about bulk PCB repair on this forum (not hard to find) but none replied (including your friend)
then i sent to one Chinese friend who did it (and got paid).
@fzabkar
not strange, you may look @ those 88ixxxx MCU`s and will know in both WD/SAM.
