按User guide中的6. Formatting the SSD (required for the first-time)的操作格式化SSD时，
在输入命令1以后提示Partition 1 is already defined, delete it before re-adding，可以直接输入命令d删除吗？还是说明我的SSD不需要格式化操作了？
由于没有看到user guide中有要删除的操作，不敢轻易操作，还请帮忙确认下该问题，
如下是串口打印数据

Nancy Wang：
你的SSD已经做过格式化了，只有第一次需要格式化。
Formatting is required only during the first boot after attaching the SSD. For the subsequent iteration, this step can be skipped. The following steps explain the procedure to do the same.
你之前应该是有过相关操作吧。
,
Ruijie Zhu：
之前没有操作过这个，如果确认已经格式化了，那我就不操作了，谢谢。
,
Nancy Wang：
是的，看提示已经格式化了，应该可以通过P指令查看吧，输入d指令删除也是可以的。
