同意cabe,不对主板改动,通过主板内置IDE接口直接接2.5寸硬盘,我也没遇到问题,工作稳定。
查了一下,2.5寸硬盘(希捷的、日立的)的启动电流一般在1A,2*7805供电,所以问题应该不大。
关于UBS接口的兼容或或者说稳定性的问题,还需要解决。因为大多情况下,外接U盘和移动硬盘,APE都认得出来,但是总有偶尔认不出来的情况,下面是用串口抓的LOG
1) 插上U盘(移动硬盘?)开机,认不到U盘(移动硬盘?)的开机LOG:

偶遇到不认U盘或移动硬盘的时候(反复开关机、插拔都不凑效),我是这样处理的:
1)拔下U盘
2)选择“关闭机器”--〉“重启”
3)选择“关闭机器”--〉“关机” 或者 直接按遥控按钮关机
4)把U盘插回APE的USB接口上
5)开机
然后APE就可以找到USB接口上的设备了,我的机器上试过目前成功率100%
但是,刚才看了sun100的帖子,我的办法在他的机器上未能凑效,可能是因为机器脾气不同或者个体差异?
嗨!没有什么方法可以包治百病呀! |
