Amir sold a laptop, used, on E-Bay. Mistake 1.
Amir didn't think to wipe the drive on the laptop. There were lots of interesting pictures, and more, on the drive. Mistake 2. Big mistake.
Oh yeah, the laptop didn't work, and it lacked features as advertised. Mistakes 3 and 4.
Amir took 2 months to send the laptop to the purchaser, and ignored repeated refund requests from the purchaser. Mistakes 5 and 6.
The guy who purchased it knew how to remove the hard drive and extract the contents. And he knew how to create a blog. Now that blog, The Broken Laptop I Sold On Ebay, and subsequent blog Amir Massoud Tofangsazan: The Blog Continues is Amir's problem. (Note 8/17): The latter selection has more relevant content; the former appears to have mutated into a splog.
Always, and I mean Always, Clean the Hard Drive Before Dumping Your PC. I'll bet Amir will, the next time.
