您是否需要在仅数据驱动器的开头保留2014年的免费扇区?

Let's assume you use a new drive as a secondary drive in you PC and plan to store only your data there. (In my case, it's %USERS% of Windows and /home of Linux. The programs and system will be left on the primary drive, which we don't consider in this question.) Let's further assume that you use GPT as the partitioning scheme. However, apparently, gdisk won't allow you to use all the space:

Command (? for help): n
Partition number (1-128, default 1): 
First sector (34-1000204287, default = 2048) or {+-}size{KMGTP}: 34
Information: Moved requested sector from 34 to 2048 in
order to align on 2048-sector boundaries.
Use 'l' on the experts' menu to adjust alignment

如果您计划从该驱动器引导并将一些引导代码放置在第一个分区之前,则AFAIK保留2014 = 2048-34个扇区非常有用。但是,您计划有一个仅数据的辅助驱动器。您永远不会从中启动。此外,可能会降低性能或增加磨损。但是,那么您最好将您的写访问权限与4 KiB或512 KiB边界对齐,并且文件系统本身的开头是否与1 MiB(= 2048扇区* 512字节/扇区)边界对齐,就不会发挥太大的作用。角色。

因此,如果您覆盖此限制并在扇区34处启动分区(例如NTFS或ext4),那会出什么问题?
