这是一个创建于 2078 天前的主题，其中的信息可能已经有所发展或是发生改变。

各位高手, 我新买了一个英特尔的 nuc 和英特尔的 s3610 的 hp 的 OEM 盘(系统安装在 m2 接口的 970pro 上, s3610 为 sata 接口). 将 s3610 插入 2.5 寸硬盘位后进入系统不识别硬盘, 具体情况如下:

输入 lshw 能找到该硬盘:

 *-scsi
      physical id: 1
      logical name: scsi2
      capabilities: emulated
    *-disk
         description: ATA Disk
         product: LK1600GEYMV
         physical id: 0.0.0
         bus info: scsi@2:0.0.0
         logical name: /dev/sda
         version: HPG2
         serial: BTHC73260CVW1P6PGN
         configuration: ansiversion=5 logicalsectorsize=512 sectorsize=4096

而且 smartctl -a /dev/sda 可显示该硬盘 smart 信息.

=== START OF INFORMATION SECTION === Device Model: LK1600GEYMV Serial Number: 删除 LU WWN Device Id: 5 5cd2e4 14deb2074 Firmware Version: 4IWTHPG2 Rotation Rate: Solid State Device Form Factor: 2.5 inches Device is: Not in smartctl database [for details use: -P showall] ATA Version is: ACS-3, ATA8-ACS T13/1699-D revision 6 SATA Version is: SATA 3.1, 6.0 Gb/s (current: 6.0 Gb/s) Local Time is: Mon Mar 18 16:14:23 2019 CST SMART support is: Available - device has SMART capability. SMART support is: Enabled

但是 lsblk, fdisk 均不显示该硬盘, 只会显示 nvme0, 但是运行 ls /dev/sd* 可以看到 /dev/sda.

尝试对 /dev/sda 进行分区会显示:

fdisk: cannot open /dev/sda: No such file or directory

请教这种情况下该如何设置使得硬盘可以正常工作?

PS: 2.5 寸硬盘位插一块日历的 500G 硬盘可以正常识别. S3610 插在外接供电的 sata 转 usb 口上也可以被同一个系统正常识别.

我对 linux 不是很在行, 第一次遇到这样的情况.

补充:

我尝试对 /dev/sda 测速:

$hdparm -t /dev/sda

显示结果如下:

/dev/sda:
Timing buffered disk reads: read() hit EOF - device too small

@ooxxcc 请问这种情况有没有可能是供电不足引起的呀? s3610 供电是 5V 1.4A.

ooxxcc

2019-03-18 19:02:31 +08:00

@zhuzhi90 有可能，反正 dmesg 提示是有设备，没媒介（类似有光驱没光盘）

2019-03-18 20:21:37 +08:00

我又去查了下资料:

s3610 的 2.5-inch 1.6T 盘在仅有 5V 供电情况下的功耗(仅列出写, 读取模式功耗较低):

Active Write - RMS Average: 6.8w
Active Write - Burst: 10.7w
Active Write - Max Burst: 12.2w

尖峰概率约为 0.25%.

nuc sata 供电口是 5 脚, 分别是 5v, 5v, 3.3v, 接地, 接地, 型号是 Molex* part number 53398-0571.
去查了生产商的资料, 电流最大值是 1A per contact. nuc 实际接了 1,2,4,5 针脚, 也就是 5v 供电最大 2A, 就 10w.

这样看供电是肯定不足了.

官网查得 860evo 2T 的功耗才平均 3w, 最大 4w, 西部数据蓝盘 ssd 2TB 的功耗最大也就 3.8w.

结论就是: 家用 nuc 别上企业盘...自作自受.
当时想着企业盘, 是 mlc, 耐用度又高...没想到碰到供电不足的问题.

BIOS 里开 AHCI 了吗

zhuzhi90

2019-03-19 18:42:28 +08:00

@wsy2220 嗯, 开了的. MBR, GPT 分区都试了.

2019-03-19 18:43:55 +08:00

今天我用 860evo 2TB 重新试了, 成功认盘. 目前我倾向于问题是由供电不足引起的.

我在外网翻了一些论坛, 发现也有人用企业盘出现问题, 他解决的方法是外接供电和 sata 线. 我不想折腾了, 860evo 能用就好了. 企业盘作为 mlc 的 sata 盘, 当做 "传家宝" 好了...
