挖矿设备鸡屁股 HPA(2018.5.15更新) Host Protected Area 是利用硬盘的ATA指令，在硬盘后部建立一个系统不可访问的区域。HPA在BIOS中和操作系统中均不可见。

目前搞不定 没有ATA的工具 访问不了HPA区域 sudo hdparm -NpABC /dev/sdb
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 Caution: invalid backup GPT header, but valid main header; regenerating backup header from main header. Warning! Main and backup partition tables differ! Use the 'c' and 'e' options on the recovery & transformation menu to examine the two tables. Warning! One or more CRCs don't match. You should repair the disk! **************************************************************************** Caution: Found protective or hybrid MBR and corrupt GPT. Using GPT, but disk verification and recovery are STRONGLY recommended. **************************************************************************** GPT data structures destroyed! You may now partition the disk using fdisk or other utilities. The operation has completed successfully.
看现象为GPT分区的首部和备份的尾部不对应
1 The backup GPT table is corrupt, but the primary appears OK, so that will be used.
这样的u盘格式化后不能挂载

N1 挂机盘 还有一种格式化之后也可以反复挂载，看起来GPT尾部的分区也被干掉了，但是可以使用，u盘拆开了，也看不出来什么，log也没什么异常。。。。
