fdisk 파티션이 2048 부터 시작하는 이유

결론은 파티션 정보로 인해서 그정도는 띄어놔야 한다?

63은 CHS 방식으로 파티션 나눌때나 그랬고

이제 더 커진 이유는 GPT로 인해서 크게크게?

Because your old disc was partitioned with a old utility, such as the Linux fdisk, that uselessly implemented track-alignment using the entirely fake disc geometry that you see reported, and your new disc has been or is being partitioned by a newer utility that (by default) aligns to 1MiB boundaries instead.

In other words, the LBA sector number 63 corresponds to cylinder 0, head 1, sector 1 in the CHS format, which is the first sector you can use in the MBR format. However, the number 63 is not divisible by 8, which causes a problem with 4K drives, so some modern tools starts the first partition at 2048 which also provides future GPT compatibility. – billc.cn Oct 31 '11 at 23:48
