99.9% of the time, YOU DONT NEED SOFTWARE!
-I just crashed my laptop harddrive, xp system.
-Assuming you cant get it to boot back up, take hard drive out of your lap top.
-Plug hard drive to another computer as a seconday slave drive, you will need adaptors, the easiest is get an adaptor from your hard drive to your usb port on your working computer.
-when you do that, your computer usb port should recognize a new drive.
-open it and you should be able to drag your information out to the new computer.
-when trying this solution, when you try to click on your drive and it comes up with a drive error, try plugging it into a mac/apple computer. macs don't care if your drive has errors, it will still open it. this is what i end up doing.
-my crashed hard drive was dying, it kept on stopping when i was recovering my data, so thats probably why it crashed, and corrupted some files.
-hope this helps, back up your files people! get an extarnal harddrive, it will save you headaches.
