This 500 GB Toshiba laptop hard drive model MK5059GSX – Was presented to us by a client last week with a head crash. The client had opened the drive on his dining room table after watching a YouTube Video. If your data is important to you…DO NOT DO THIS EVER!!! – Leave it to the pro’s – Luckily we were successful at fitting a set of temporary heads and now have the drive imaging. A bullet dodged for our client I would say.
