What do you mean by "transferring data from other storage to this one"
? These are main memory (RAM) ECC errors and have nothing to do with
disk storage, networking, or anything else.
and, 'writing data to it', its not clear what the 'it' is referring to.
ECC errors can happen anywhere. It can be that the data is corrupted while it
is transmitted to the storage device. Or the data can degrade while stored.
And of course, on the transmission from the storage you have another chance
to screw it up.
ECC errors in RAM will be detected when data is read back from RAM and
the associated ECC is incorrect. the ECC codes are generated when the
RAM is written to.
So I dunno what you're talking about 'transmitted ot storage devices',
etc.... Disk drives have their OWN ECC, this is quite different and
seperate and has no relationship to the ECC in main memory.
