已解决：水星4530R挂载移动硬盘不稳定的问题

918

插上后第一次访问没问题，但时间一长再访问就出问题不能访问了
硬盘是500g的WD5000LPVX ，硬盘盒是 奥睿科 2588US3-BK(NS1068的芯片)
日志如下：
看到 Buffer I/O error on device sda2的错误，fat32，ext4，ntfs格式都测试过都同样的问题
感觉不像供电不主，因为刚插上去好用的，时间长了才出问题，硬盘休眠选项也改过但没用

------更新
换了usb2.0的硬盘盒还是不行，估计是其他问题了

------最后更新
问题解决了，果然是供电不足的问题，外接一个供电就稳定了

移动硬盘在电脑上使用一点问题都没有，用usb3也很正常，实在搞不明白了。
以前用的一个40g的老移动硬盘都好好的

你好像很美味

你换个2。0盒子试试，可能是op驱动问题，

谢谢，估计也只能换个2.0的盒子试试看了

悲剧，新买了个2.0的硬盘盒，有一摸一样的问题。
难道是wd的硬盘问题嘛？
或者真的是供电不主

找个带供电的USB HUB试试，之前看过一例也是这个问题，用带供电的HUB解决

918

问题解决了，果然是供电不足的问题，新买的2.0硬盘盒连接线有个外接供电口，上面接了个usb充电器就没问题了。
奇怪的是我日立的硬盘上面写1a电流，没外接电源我都可以用，但西部数据的写0.55a电流就不行了，给这个迷惑了

看来西数笔记本硬盘不靠谱啊。。。
