3 HDDs moved from XP, only one recognised in Win7
Having built a new Win7x64 computer with 1x SSD and 2x Seagate HDDs I then moved 3 nearly identical WD drives from my old Win XP machine to the new one. However although they all show up in device manager and system information only one appears in Disk Management & Windows Explorer.
The drives moved are 500GB Western Digital WD5000AKS full of data. It doesn't matter whether I mount the invisible drives internally or externally (I have a Coolermaster CM690 II Advanced which has an external SATA port on the top).
I've put the invisible drive back in the old XP machine to check it and it still works fine. (It was still powered from the new Win7 m/c as I simply rerouted the SATA cable so I know it is receiving enough power.)
Any ideas why one will show and not the others?
