I am not sure if what you claim is meaningful. A single bit of data loss is a data loss, no matter what the file size is. If you meant you could fix the 1-bit error easily in the 1KB case, as you have just 8K bits to flip through, then it makes much more sense. If you split the big 10GB file into smaller chunks of 1KB (at which error detection/correction is done), then the fault becomes much more manageable.
