stm32 挂载FatFs时格式化硬盘使用函数f_mkfs出错
在f_mkfs之前已调用f_mout函数返回无文件系统正常，但是格式化SD卡时调用f_mkfs返回1，请问一下这可能是什么导致的？

FR_OK = 0, /* (0) Succeeded */

} FRESULT;
按照这个说法应该是底层IO硬件错误，但是前面SD卡初始化已经正常了呀,问题可能出在哪里呢
即使 SD 卡初始化成功，但是在格式化时仍然有可能出现底层 IO 硬件的问题。可能是因为在格式化时需要对 SD 卡进行更复杂的读写操作，而初始化只是简单的读取 SD 卡的信息。因此，即使初始化成功，仍然可能在格式化时遇到底层 IO 硬件的问题。
除了硬件问题之外，还有一些其它的可能原因，比如使用的 FATFS 版本不兼容或者使用的 SD 卡不支持某些特定的格式化方式等。您可以先检查一下 SD 卡的规格和 FATFS 版本是否兼容，以及格式化时的参数是否正确设置。
你看看下面这几个你试着来排查：
1、硬件：错误码 FR_DISK_ERR 表示底层的 IO 硬件存在问题，可能是由于SD卡损坏或其它原因导致的。可以换SD卡或换另一个 SD 卡槽。
2、参数错误：错误码 FR_MKFS_ABORTED 表示格式化过程被中止了，可能是因为输入参数不正确。检查你的调用 f_mkfs 函数时的参数是否对了没有；
3、访问权限问题：错误码 FR_DENIED 表示访问权限受到了限制。检查 SD 卡的访问权限是否正确设置。
4、写保护问题：错误码 FR_WRITE_PROTECTED 表示 SD 卡处于写保护状态，可能需要关闭写保护才能格式化。都试试吧
