One of the most common cases that people experience is the loss of data from an external 或者 portable hard drive. These are prone to damage because people tend to carry them around in backpacks and briefcases which might lead to them getting tipped over. These devices have very little shock protection and most of the time they are damaged because they were dropped 或者 received some sort of impact.
In case of your laptop 或者 desktop, they might be on their way to crashing if 你 find that they are running very slow 或者 won’t turn on at all. As it is with portable devices, one of the most common reasons is your laptop receiving some kind of impact 由 dropping 或者 banging. This can easily damage the internal components of the hard drive. Another common cause can be power outrages. If the power is turned off abruptly, the heads of the drive can slam into the 大盘子, 拼盘 instead of resting where they are supposed to.
Usually, 你 only get one chance to recover the 迷失 data from your hard drive and the task is best left to professionals. Sometimes “computer and IT data recovery companies” offer another way to recover data. This usually means running over-the-counter software which attempts to read the data from a crashed drive. In most cases, all this does is make things worse and the data gets 更多 complicated 或者 even impossible to recover.
As 说 earlier, in order to recover the data from your hard drive, the cause of its failure is required to be understood. A successful diagnosis of your failed drive is the key factor that determines if the data can be recovered 或者 if it is 迷失 forever. The hard drive has to be temporarily repaired before that data can be recovered. This cannot be done without knowing the cause of the failure which is why it is important. The correct diagnosis of the drive is what makes some companies competent enough to deal with recovery services.
It is important to note that the repairs that are done are temporary and only for the purpose of retrieving your data, not for restoring the drive again in your system.
