on your slave drive & it shows up in Disk Management, you need to assign it a new drive letter to correspond with the new OS.
Right Click on the drine in Disk Management & assign whatever letter comes up next. You can then access thru "My Computer"
PS: Make sure disk is marked as active (same right click procedure)
I have a Dell Dimension 4100 desktop with Windows XP Home Edition. Few years later I added a second internal hard drive which computer recognized after installation and I used it several years with no problem. Recently the Operating System in the Primary Hard drive crashed and I reformatted the drive. Everything went OK and the computer recognized all the external hardware such as external hard drive,printer,scanner etc. but I can not find my secondary slave hard drive in My Computer which used to be there prior to the crash. If I open up Computer/Disk management window I see that this secondary hard drive is registered there as active and healty. Few Dell people tried to help me to solve my problem but without luck. Please help. Thanks
