　　U盘出现大大小小的问题，很多时候我们都可以通过一些措施及软件来解决，但是如果出现的是硬件故障，很多人就不知道怎样处理了，硬件故障一般出现在劣质的U盘上，由于U盘主体线路板的结构非常简单，其生产工艺也不需要太高深的技巧，因此多量化生产的后果造就了重量轻质的局面。

　　由于U盘本身质量问题，我们常会遇到这些情况：比如U盘接到电脑引起电脑死机、拷文件过程中U盘长时间卡住、拷文件的过程中U盘掉线、操作系统报不稳定设备后自动退出、设备接到电脑USB接口上时，完全没有识别到设备等情况。这些问题在一定程度上制约着对U盘内资料的获取的时效性，只需补焊或者更换电路板就可以解决。

　　导致U盘数据丢失的还有一个重要原因——固件层损坏，这得归结于人为因素。人们在使用U盘时常常不按安全移除设备的步骤拔取U盘，或者长时间把U盘与电脑连接都会导致U盘固件层的损坏，此外在传输数据的时候突然断电等意外情况也会使U盘内数据丢失。U盘固件层的一旦损坏，就很难修理了。

　　对于U盘固件层损坏而导致的数据丢失，建议尽量找大型的专业数据恢复公司来做。由于专门针对这类U盘固件层问题的数据恢复工具全球仅为两种——ACE-FLASH和效率源FLASH数据恢复大师，这两款FLASH芯片数据恢复工具对U盘恢复数据也同样不错，但对操作者要求更高。这两款软件在数据恢复工程师和U盘数据恢复工具设备的配备上也很强，如果说非要把ACE-FLASH和效率源FLASH数据恢复大师做一个选择性的比较。

　　如果您的U盘为国内生产，还是选择效率源FLASH数据恢复大师比较稳妥，这是因为ACE-FLASH在研发时只针对国际上主流的几款U盘品牌而造成的尴尬局面。ACE-FLASH忽略对其他国家品牌的试验，在一定程度上导致与市面上大多小品牌U盘的兼容性，而对于中国这个U盘制造大国来说不能不说是U盘数据恢复技术的遗憾。
