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 panic about all the files you have lost. Well now, I will tell you how I got them back! In the past I have formatted my hard drive by accident a few times and the first time it happened I refused to believe my data was gone for good. I accidentally deleted the partition on my drive and in seconds 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 a list of free data recovery software Luckily I had access to a back up computer where I was able to search the web 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 a big table of contents on your disk which tells your computer what files are stored on the disk and where to find them. When you delete some information from your computer all that happens is it gets removed from the table of contents (not the actual disk) so there is no record of your file or where it is 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 and 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 erase everything as I (and so many others) have done and want to get it back. As far as I know this is true on all types of data storage from internal and external hard drives to usb memory sticks and memory cards.

I also learnt that the way data recovery software usually works is by reading your entire hard drive and 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 erase 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.
