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.
Storage - anything that can store data. ECC is a generic term and covers all kinds of checksumming algorithms. I was talking pretty generic - don't care if ram, caches, nand-flash, ficon or anything else.
I was trying to get across that its hard to pinpoint where your bits flipped - in the storage device, on the transmission there or back.
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.
Right - and again I was using generic terms because at the time that I posted, the question was if the RAM is bad or any other component... :)
