我对 500gb 固态硬盘 (sda) 做了一些“魔术”，现在它的大小只显示 1gb。我试图在谷歌上寻找一些答案，但不幸的是我没有成功。有什么想法吗？

非常感谢。J
答案1
不，不是。500GB SSD 应该有 CHS 608xx 255 63，因此 testdisk 只能“看到”损坏的分区表。您需要从 live、gparted 或任何救援棒启动，因为分区操作仅适用于卸载 ssd。打开 gparted -> 驱动器 -> 新分区表。如果这不起作用，您必须先删除所有现有分区，然后再删除新表。
答案2
sda 有一个未知的分区表“分区表：未知”。使用 gparded 或任何其他分区工具来设置 msdos 或 gpt 表。
