When a drive writes data, areas next to the actual track also get set with a slight magnetic field. When you just zero the drive, those areas retain that slight field. Going back over that area, you just have to detect when you sense that slight field.

No analysis, no questioning (or support) of the claims made, nothing like that. Even the very real problems the reviewer briefly mentions (can only write data to a FAT32 partition, for example) are quickly handwaved away and ignored.

I used to do Data Recovery (Score:5, Interesting)
It started off as a hobby, sort of. I used to work for the old WordPerfect corporation where we had customers that sent in floppies that had "REALLY IMPORTANT" documents on them that had become corrupted or partially deleted, one way or another.
Data recovery tools weren't as advanced as they are nowadays so it was a much more arduous task. I had to scour the floppies and pull off as much data as possible, mostly using the old debug command under DOS. I was mostly doing it for fun as the WordPerfect corporation didn't want to become file recovery experts. I was just into it for the challenge and to offer a nice service to our customers.
I recovered data off a floppy that had a pencil stuck through it, floppies that had been formatted (easy) partially erased by magnets (tough), and various methods of corruption and deletion - including accidentally saving a blank document over the top of an existing document... OOPS!
I was once asked "How do you recover the data?" and I had a tough time answering, as each case was different from the other. I just told them that "Performing data recovery is like running a sausage mill backwards to manufacture pigs." What comes out of the process doesn't look pretty, but its better than starting from scratch.
I then went on to recovering data from hard drives. After WordPerfect I became a 'consultant'. One Monday morning, one of my customers had their WIN NT 3.51 server hard drive crash. It was a head crash, you could hear the heads riding the platter. An awful noise that once you hear it, you know you're screwed.
I spent 16 hours pulling data from that hard drive, and once I was done (I had pulled as much data as I could) we opened up the drive to discover that the head on the bottom platter had fallen down, and had been riding there over the weekend. It had etched away at the platter for so long that the platter had actually fallen down and was sitting in a pile of HDD shavings at the bottom of the drive. Sheesh!
Over the years I collected numerous utilities for data recovery, but I started getting out of it once LBA mode drives came out and the actual hard drives were being managed internally, rather than by the OS. Not that it made it more dificult, but you saw fewer and fewer hard drive errors because MS was finally removed from their management position over the HDD data.
Anyhow, back to work...
