我最近安装了 Windows 8.1，但它停止工作并损坏了。我尝试加载 Linux 来清除我的硬盘分区，它说我的分区中总共只有 24 GB 的硬盘空间（SSD 是 256 GB）。
当我在 ununtu 上查看“磁盘”时，它还告诉我所有分区都有 24GB。
有没有简单的方法可以格式化我的整个硬盘以恢复所有丢失的空间？（我不担心里面的数据）

Warning: /dev/sdb contains GPT signatures, indicating that it has a GPT table.
However, it does not have a valid fake msdos partition table, as it should.
Perhaps it was corrupted -- possibly by a program that doesn't understand GPT
partition tables. Or perhaps you deleted the GPT table, and are now using an
msdos partition table. Is this a GPT partition table?
Yes/No? Yes
Error: The primary GPT table is corrupt, but the backup appears OK, so that will be used.
OK/Cancel? OK
