well, saving the ECC data on the same hard disk would make the solution useless because it is not rare for a hard disk to just die loosing all the data inside.
For only 40GB of data, buy abother disk and make a mirror or oven better, copy everything in DVDs.
Thanks.
I actually do have the data backed up more than once. Both on hard-disks and DVDs.
This doesn't help much though, since its enough that the file gets corrupted on the main copy, to propagate the corruption to the other copies. On occasion, I stumble onto a corrupt image and look it up in the old copies.
This happened too many times before, on various disks.
I want to be absolutely sure that such cases do not occur since this data is precious for me.
Surely there is a better way.
