I recently took two old IDE hard drives that had data on it I wanted to keep, so I used a USB 2.0 to SATA/IDE Adapter to transfer the data from my old IDE hard drives onto my Western Digital My Book 1TB external hard drive. After I transferred the data, I decided to format my two old IDE drives, by right clicking my computer, then selecting manage, then going to disk management and formatting them that way. One hard drive formatted fine noticed nothing, I noticed I took the other drive, which is a 40GB, when I went to my computer it only saw it as a 18GB, so in disk management I saw the drive, but it look like it had two 18GB parts on the same drive, so what I did was I formatted one and then still said 18GB for one, but the other said unallocated, so I formatted both and then it was one unallocated, I was able to see the hard drive of 40GB. So now after I power down my Western Digital My Book 1TB external hard drive, I see these, the two pictures I posted. When I double click on this Local Disk H, I get this message, When the My Book shuts off completely, the Local Disk H disappears. Can someone help me find a way whenever I power down my Western Digital My Book 1TB external hard drive, I don't get or see this?
