我只需要一些软件，如 IntelliJ IDEA IDE 就可以在 SSD 上运行。这就是我购买的 SSD。但 SSD 没有显示在列表中。我使用的是 DELL inspiron。该怎么办？
编辑：我更新了BIOS并重新插入 SSD。现在 SSD 显示在BIOS但在我的 Ubuntu 20.04.6 LTS 中却不行磁盘使用情况分析器或者磁盘gui。我认为我需要从
RAID ON（当前选择）转换为AHCI（在集成 SATA 硬盘控制器的 SATA 操作设置操作模式下）。但当我更改并尝试将其保存在BIOS，它显示警告操作系统可能已损坏。如何在不损坏 ubuntu 的情况下更改它？注意：另外我不确定转换是否
RAID ON会使AHCISSD 显示在 Ubuntu 20.04.6 LTS 中
