You're both leaving out part of the picture. Just like a packet on Ethernet has a header and a footer, a sector on a hard drive does as well. It has basic data to let the drive know exactly what sector on the drive it is, but it also has ECC info that allows multi-bit errors to be corrected.
Yes, true. I was thinking of that when I said "error correction methods" :-)
The move from 512 byte sectors to 4KB sectors revolves around the wasted space taken up by ECC info. With a 512 byte sector the ECC data was getting to be too high a percentage of the total raw sector size. By going to 4KB sectors, the ECC data is reduced from a percentage of the total perspective.
Ah. That's interesting. - -- Cheers / Saludos, Carlos E. R.
