西部数据

您可能遇到多个问题。

对于您所有的西部数据硬盘，我们都需要离散的 USB 设备代码...

禁用uas配置文件

我们将尝试禁用 USB3 UAS（USB 连接 SCSI），看看是否有帮助......

笔记：您可能希望查看hdparm -B和hdparm -J命令。

  -B     Get/set Advanced Power Management feature, if the drive supports
          it.  A  low  value  means aggressive power management and a high
          value means better performance.  Possible  settings  range  from
          values  1  through  127 (which permit spin-down), and values 128
          through 254 (which do not permit spin-down).  The highest degree
          of  power  management  is  attained with a setting of 1, and the
          highest I/O performance with a setting of 254.  A value  of  255
          tells  hdparm to disable Advanced Power Management altogether on
          the drive (not all drives support disabling it, but most do).

  -J     Get/set  the  Western Digital (WD) Green Drive's "idle3" timeout
          value.  This timeout controls how  often  the  drive  parks  its
          heads and enters a low power consumption state.  The factory de‐
          fault is eight (8) seconds, which is a very poor choice for  use
          with  Linux.   Leaving it at the default will result in hundreds
          of thousands of head load/unload cycles in a very  short  period
          of  time.   The  drive  mechanism  is  only rated for 300,000 to
          1,000,000 cycles, so leaving it at the default could  result  in
          premature  failure, not to mention the performance impact of the
          drive often having to wake-up before doing routine I/O.

          WD supply a WDIDLE3.EXE DOS utility for tweaking  this  setting,
          and you should use that program instead of hdparm if at all pos‐
          sible.  The reverse-engineered implementation in hdparm  is  not
          as  complete  as  the  original official program, even though it
          does seem to work on at a least a few drives.  A full power  cy‐
          cle  is  required  for any change in setting to take effect, re‐
          gardless of which program is used to tweak things.

          A setting of 30 seconds is recommended for Linux use.  Permitted
          values  are  from 8 to 12 seconds, and from 30 to 300 seconds in
          30-second increments.  Specify a value of zero  (0)  to  disable
          the WD idle3 timer completely (NOT RECOMMENDED!).
