监控SAS硬盘无法正确识别与格式化解决
记录下2021年在挖XCH币的时候本地收了20个4T希捷SAS存储盘， 但是都无法正确识别与格式化的问题解决方法。
这里感谢阿夜帮忙排查问题和折腾成功㊗️

这里用了垃圾山寨虚标电源 ！供电不足会导致磁盘使用不了，换电源！

换过电源后 依次使用-i检查8个硬盘是否通电正常，如果有不正常再次检查硬件上哪里有问题。可以看到正确识别出磁盘分区是520
如果没有问题就可以把 520 扇区大小转化成512 ，操作如下。
./SeaChest_Format_x86_64-linux-gnu -d /dev/sg2 --formatUnit 512 --fastFormat 2 --confirm this-will-erase-data
--formatUnit 512 （格式化512分区
--fastFormat 2 （快速格式化不保留数据
--confirm this-will-erase-data （擦除所有数据确认
出现
/dev/sg9 - ST4000NM0023 - Z1Z35SHB0000C424A81Y - SCSI
Format Unit
Performing SCSI drive format.
Depending on the format request, this could take minutes to hours or days.
Do not remove power or attempt other access as interrupting it may make
the drive unusable or require performing this command again!!
代表正在格式化中 ，结束后一次停止硬盘 换下一批继续如上操作
./SeaChest_PowerControl_x86_64-linux-gnu -d /dev/sg9 --spinDown
我的4T SAS硬盘 20个硬盘测试大概需要14小时，其中有一块硬盘格式化了3天，八成没戏翻车了。
