I have the same issue with my 1564. I have no idea why Dell has decided to configure their harddrives with these partitions, but they should fix this immediately. My first laptop ordered back in March had the 60gig C drive. I talked to technical support and the individual remoted in (big mistake) and attempted to change the configuration with Windows partition manager which did not work. So the so called techy had me stick in the Windows CD so he could reformat. Needless to say that messed up the laptop so it did not even look like the image that it orginally came with. It looked like a plain vanilla Windows 7 image. Dell offered to send me a new hard drice configured correctly. To my surprise I received 2 different HD's. Neither would boot up. So I asked for a replacement It took a month to get a replacement. Guess What. Same issue with hard drive partitioned. The latest is that I am waiting for a senior tech from the escalation department to call and fix this laptop. I am not very confident. Whoever at Dell decided to partition the HD's like this should be fired
