我正在使用 ubuntu 20.04,我想创建正好 500 MB 的新分区磁盘。但是,fdisk 将其调整为 512MiB 有什么方法可以创建正好 500MB 的磁盘大小?
ric@Eric:~/Downloads$ sudo fdisk /dev/sda
Welcome to fdisk (util-linux 2.34).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.

这可以用数学来解决!这些扇区的大小为 512 字节,这意味着您需要一百万才能拥有 500MB。
但是,如果出现以下情况,请准备好数字不完全是 500MB:
多年来,很多数学都涉及如何在存储设备上写入和组织数据,并且有些情况对于设备的长期使用并不理想。
