NEED TO RECOVER FILES FROM A HDD AFTER IT HAS BEEN FORMATTED
As this is my first blog I wanted to pass on some information about a subject that has caused me a lot of problems in the past….. Data recovery It hasn’t happened too often you learn from your mistakes luckily but when it does happen you are left feeling sick with worry about all the files you have lost. Well now I will tell you how I got them back In the past I have re-partitioned my hard drive by accident a few times & the first time it happened I refused to believe my data was gone for good. I accidentally deleted the partition on my drive & in an instant all my data was gone I knew all my files were still written on the disk it’s just there was no record of where they were all I had to do was find a program that could re-build the list of all my files so my computer knew what was actually on my disk. Here is list of free data recovery software Luckily I had access to a second computer where I was able to search the internet for information on recovering lost data I soon found out that when you erase a file on your computer you don’t actually delete it what happens is this There is big table of contents on your disk which tells your computer what files are stored on the disk & where to find them. When you delete some information from your computer all that happens is it gets removed form table of contents not the actual disk so there is no record of your file or where it on the disk. Your file is still on the disk but the computer doesn’t know it’s there so it thinks that portion of the disk is empty. Then when your computer needs to write something new to the disk you save a new file it looks in the table of contents for a blank section of disk & then writes to it so your deleted file could be sitting around on your disk for months before it gets overwritten with new data. This is very scary if you have sensitive information that you want to destroy but is very handy if you accidentally delete everything as I and so many others have done & want to get it back. As far as I know this is true on all types of data storage from internal & external hard drives to usb memory sticks & memory cards.
I also learnt that the way data recovery software usually works is by scanning your entire hard drive & if it finds any files that are not in the table of contents it simply adds them in effectively un-deleting everything on your drive Job done You just have to make sure that if you delete something you want to get back don’t write big files to your disk as this could over-write all of your deleted file making it very difficult to retrieve.
I hope this has been helpful.
