我做了一个labview双通道电压数据采集程序,当储存路径为计算机硬盘时,就会出现程序中途死机,数据也就终止采集(控制面板显示正常、计算机运行正常);当数据储存路径改为外围U盘时就没有这种情况,这是为什么呢?请各位大神给点帮助,谢谢!

Hi,
就你的问题描述来说,很难定位,虽然你已经做了交叉验证。
1. 存储路径为计算机硬盘的时候会导致程序中途死机,这个死机是指程序崩溃?还是程序卡住?还是程序报错?错误信息是什么?
2. 该现象是否是偶发?还是经过一段时间之后必然产生?
3. 数据的写入速率是多少?(按照道理来说,利用合适的硬盘写入策略,你的硬盘写入速率应该达到80MB+ --5400rpm的标准硬盘,应该可以满足你的一般要求了) 即便没有写入成功,应该也会有其他报错信息,比如数据采集缓冲区溢出等等。
4. 硬盘休眠应该对此影响不大,可以考虑把数据写入到系统盘符所在的逻辑分区。
5. 最后,最后能怀疑的就是你的硬盘有坏道了,这种情况下系统蓝屏死机的概率很高啊。
Good Luck!
