朋友有台server，是dell的1950
故障现象：
突然之间大堆的
“Input/output error”、”Bus error”
然后有的分区还被重新mount成只读的
重启的时候
系统提示：
”

Memory/Battery problems were detected. The adapter has recovered, but cached data was lost. Press any key to continue.

”
在这里找到dell官方的说法：

This message occurs under the following conditions:

• the adapter detects that the cache in the controller cache has not yet been written to the disk subsystem
• the boot block detects an ECC error while performing its cache checking routine during initialization
• the controller then discards the cache rather than sending it to the disk subsystem because the data integrity cannot be guaranteed

To resolve this problem, allow the battery to charge fully. If the problem persists, the battery or adapter DIMM might be faulty. In that case, contact Dell Technical Support.

看来不一定是硬盘坏
而有可能是raid卡要换电池了
