I can't access the files I've transferred to my Kanguru QS3 1.5Tb Hard Drive from my own pc, however can when plugged into a secondary computer. Both pcs run Win 7. I did attempt a small change on my own computer when I decided to try to make a secondary partition on the main hard drive of my computer. I had followed instructions I found on microsoft's knowledge base to create the drive. After making the drive I noticed things had slown down some. I then went back to the knowledge base to figure out how to successfully delete the partition and reallocate that space back. Things are still running slow even after that, and I still cannot access that drive, or any other drive that I have attempted to access. But then another of my drives works perfectly, which is also an external hard drive requiring external power, my Seagate FreeAgent. How can this one still show up while the other can't, and are these related some how?
