Why should you oppose software recovery and recovery after data loss?

When a client used pirated software at home yesterday, everything on the hard drive was removed.

Lenovo's data recovery in some cases, more firmly I oppose the use of software recovery and casual people to recover attitude.

In the previous hard drive data recovery era, often have the firmware is written wrong, write chaos situation, also has the circuit board CPU, ROM chip burned, there is also the phenomenon of the disc was scratched by man; given that hard drive data recovery has evolved over the years, both theory and technology have matured, and everyone who does data recovery will be touched.

Now in the era of fragmentation data recovery, there are some things that are not so easy to spot.

Anyone who works with a computer seems to feel that he is a "computer whiz": software, with a few mouse points, what work is done, super simple. There are so many data recovery software online, the price is super cheap, and some customers come up and ask: "What data recovery software do you use?" Or ask: "Is there any more advanced software?" ”

So I happen to have a few cases of data loss using software recovery to see how the data is being destroyed:

Case one,

650) this.width=650; "src=" Http://www.shannon.net.cn/images/stories/about/blog/destroyed-1.jpg "alt=" Destroyed-1.jpg "height=" 290 "width=" 853 "/>

is a digital camera SD card, the recording was mistakenly deleted. ? vi_0428.dat is the file that the customer wants to recover.

Make a timeline based on the information:

2014/10/25 12:05:20 The customer took this video and then removed the

2014/10/27 06:29:54 Customer Self-use software recovery, no success

2014/10/29 14:55:53 The client recovered without success

And look at this ? vi_0428.dat file that the customer wants to restore, and its address is sector:16704;

Take a look at the System Volume infomation This directory, its address is: sector:16704;

You say how so coincidence, is the customer to restore the file header address, but the System Volume information This directory to be stored here.

Take a look at these directories from QQ Records to Mpfile , which are stored in the front data area of the. vi_0428.dat file.

But the vi_0428.dat file finally recovered.

Case two,

650) this.width=650; "src=" Http://www.shannon.net.cn/images/stories/about/blog/destroyed-2.jpg "alt=" Destroyed-2.jpg "height=" 368 "width=" 651 "/>

Is the appearance of a deleted video file after recovery.

This customer most people without words: The first is the night to ask for home recovery, did not go, the next day to find someone to recover, did not succeed in the evening to ask for home recovery, did not go, the third day to recover, or unsuccessful; by the fourth day, the customer finally came, according to customers said the software has been online recovery. It turned out to be like this after I recovered from the debris. With Winhex view, the SD card sector has been regular, the interval zeroed. As to why this happens, it is no longer a test.
