I've just formatted 7 IDE hard drives. These have been stored in antistatic bags in a smoke free home for a few years. Each hard drive works. This lot totals 500 GB, hence, half a terabyte.These would be great for someone who has a few empty external drive cases, or for a person who likes to build computers and doesn't have any hard drives to go in them.The following IDE hard drives are what I have.Maxtor 200 GB 3.5 seriesMaxtor 20 GB----Western Digital:WD1600 (160 GB)WD800 (80 GB)WD200 (20 GB)WD100 (10 GB)----Seagate 10 GB
