前言
前段时间迷上了捡垃圾，在二手市场里到处乱逛，看上了这块东芝的5SRB384C，卖家报价150欧，我砍价到120欧 运费一共127欧。到手的时候还美滋滋的觉得赚到了。
没想到插上R730（H730）阵列卡之后显示不支持，扇区大小是520b：
但是这个硬盘的接口是图中这样的，中间7根金手指不是在背面而是在正面，和我见过的其他SAS盘不一样。同时它还附带了一个转接框，把中间的金手指转换到背面。
后面我又尝试了把这张盘插到外置阵列柜中，依然无效。
解决方案
首先你要有一个支持SAS的直通卡，我之前卡住好几个月就是因为没有直通卡，差点就放弃了。前段时间收了一个R230，内置的H330阵列卡我没啥用，就拿来试试看刷直通，也是一堆坑，后面有空了细说一下吧.....
总之在使用HBA直连硬盘后，通过`sg_scan`找到需要格式化的硬盘，这里是/dev/sg1
root@PVE-BE-105:~# sg_scan -i
/dev/sg0: scsi0 channel=0 id=0 lun=0
ATA Micron_5200_MTFD U020 [rmb=0 cmdq=1 pqual=0 pdev=0x0]
/dev/sg1: scsi0 channel=0 id=1 lun=0
TOSHIBA 5SRB384C EMC3840 QC4F [rmb=0 cmdq=1 pqual=0 pdev=0x0]
格式化前先看一下这个盘的扇区情况，确实是520的block size，也可以看到这里的磁盘大小是3.82TB而不是3.84TB：
root@PVE-BE-105:~# sg_readcap /dev/sg1
READ CAPACITY (10) indicates device capacity too large
now trying 16 byte cdb variant
Read Capacity results:
Protection: prot_en=0, p_type=0, p_i_exponent=0
Logical block provisioning: lbpme=1, lbprz=1
Last LBA=7348420607 (0x1b5ffffff), Number of logical blocks=7348420608
Logical block length=520 bytes
Logical blocks per physical block exponent=3 [so physical block length=4160 bytes]
Lowest aligned LBA=0
Hence:
Device size: 3821178716160 bytes, 3644160.0 MiB, 3821.18 GB, 3.82 TB
然后开始重新格式化扇区，设置扇区大小为512。这里要等很久很久，我没有用screen执行而是直接在PVE的console里执行的，按下回车就后悔了，生怕断掉。。。。

来确认一下扇区是否格式化完成了，可以看到变成了512的block size，并且空间变成了3.84TB：
root@PVE-BE-105:~# sg_readcap /dev/sg1
READ CAPACITY (10) indicates device capacity too large
now trying 16 byte cdb variant
Read Capacity results:

Lowest aligned LBA=0
Hence:
Device size: 3840774504448 bytes, 3662848.0 MiB, 3840.77 GB, 3.84 TB
但是lsblk的时候发现磁盘还是不可用状态：

结语
少捡垃圾！！！太费时间了，前前后后至少有十整天在弄这个东西，劳心费神！得不偿失！
而且最气人的是这个盘的smart终于可以读了，已经是战损级别成色了：
