Samsung with bad head??

[pclab]

Hi

I got a HD253GJ with a problem on the PCB (it wouldn't spin up the platters).
So I ordered a donor 3 months apart of date of manufacture.
I have made a hot swap, but I get this terminal.
This means Head is dead, right?
Thanks

I have made a hot swap ...

Why? Wouldn't you just need to transfer the patient ROM to the donor PCB?

to me not a good choice for HOT SWAP...
can you read the rom of patient and donor and show us Dump info ?

Hi
Why not a good choice?

[MindMergepk]

imagine i tried a hot swap on HD502HJ with same month of manufacturing and it was not compatible..

if you read rom of patient and donor and compare the dump info you will have the answer

[northwind]

Why you do hotswap and not just swap rom from patient to donor pcb?

Alternatively, you can use donor pcb directly and write overlays without swapping rom.

[pclab]

I'l try that too.
Thanks
