It's a $34 piece of hardware that puts a hole in DD disks to make disk drives think that they're HD disks. Here are an excerpt from the ad: ...will convert your low cost 3 1/2" 720K disks to work at high cost 1.44MB disks with NO COMPROMISE in media reliability. [...] This is possible because there is no difference at all between the media in 720K and 1.44MB disks used today! ... This ad is EXTREMELY bogus! I can tell many horror stories of people who have attempted to do this, only to lose data in a matter of days. I know that there IS a diffenence in the type of media used in DD and HD disks, but this ad really surprised me. I'd like to know what you netters think of this ad. I hate to think of all the people out there that believe this ad. Please post your comments to the net. J.
