Removable storage might be a card reader for 4 different kind of cards. Not a problem anyway, so there is no need to repair it. However, https://www.google.com/search?q=xp+hide+drive+letter will tell you how to hide them, if you want.
About that second hard drive:
1. What does Disk Management say about it?
2. Does it have a drive letter?
3. If the driver letter is, say, k:, what happens if (in the command prompt) you say format k: (+ enter)?
When I turn on my pc and it boots up I click on my computer it displays a list of items that are on my computer but under the heading .....Devices with Removable Storage I have my cdrom drive and 4 removable disks lettered E, F, G, H. But I have no removable storage connected to my PC, how can I repair this problem. This pc is new to me bought it second hand it has windows XP home. On my old pc it only recognised removable storage if it was plugged in. How can I fix this problem. Also have purchased 120gb hard drive that I want to use as a slave with the original hard drive and it won't let me format it
