Query: It does not work with all computers

We bought one but it did not work with HP computers. After hours of tech support they sent us several "new" items which had the same problem. They finally sent a new one which (surprise surprise ) ......... did not work as well. "It Did not work" means that it stopped the backup and the computer could not see the drive.In some computers it does work ( Dell ) for example ( after they sent us several items, of course) but with HP, forget about it.We wanted to return it and get the money back - they refused.Good policy for the company, bad for the consumer.
