Avoid Data Corruption
What cause Hard disk drive (HDD) malfunction or data corruption?
Due to HDD platter is spinning when it is powered on. And the HDD head is just very close to the platter.
1) Power failure when computer is writing data on it.
2) Shocking. Example: Moving Computer when the Computer powered on.
3) HDD's platter, head and auto-parking mechanism ware and tear.
4) Spyware, Virus, Trojan infection.
5) Too frequent writing to the same location. (Example : Running Torrents software)
What cause USB flash drive (PenDrive) malfunction or data corruption?
1) Eject USB flash drive or power failure when computer is writing data on it.
2) Short circuit when insert or eject from a faulty USB port.
3) Too many read and write. Flash drives can sustain only a limited number of write and erase cycles before failure.
What cause burned CD/DVD failed to read?
1) Burner alignment is out.
2) Low quality CD/DVD chemical will dry out faster.
3) Burning CD/DVD at very high speed. (I recommend not to burn more than 16 speed.)
So, please make at least 2 copy of your data. Computer are unreliable. Raid 1 and above is still not a good solution compare to data backup.
什么原因造成硬盘驱动器(HDD)故障或数据损坏?
由于硬盘盘片在启动后,就开始旋转时。而HDD磁头又非常靠近盘片。
1)当在电脑写入资料时停电。
2)震动。例如在电脑接通电源时,移动电脑。
3)硬盘的碟,磁头和其他部件老化。
4)间谍软件,病毒,木马感染。
5)过于频繁的写入相同的位置。 (例如:Torrents软件)
什么原因造成USB闪存驱动器(随身碟)故障或数据损坏?
1)当在电脑写入资料时停电或弹出。
2)在一个坏了的USB端口插入或弹出随身碟,造成短路。
3)有太多的读取和写入。随身碟只能维持有限数量的写入和擦除。
什么原因造成CD/DVD不能读取?
1)烧录时,光碟刻录机机头校准有问题。
2)低质量的CD / DVD光碟,里面的化学液体更快干固。
3) 以非常高的速度烧录CD/DVD。 (我建议不使用超过16倍速。)
所以,请备份你的资料。电脑是不稳定的。
备注: Raid 1或以上的安全性还是不能跟备份做比较。
