I think I figured out what's happening. The PC is a Lenovo IdeaPad Y570 with RapidDrive technology. Apparently, this combines both HD and SSD to make it appear that it's one drive, using the SSD for operating system files in a way that's transparent to the operating system; it presents a simple C: drive. The D: drive that I thought was the SSD is apparently a recovery partition of about half of the SSD space with software and drivers on it. So, it's not a real hybrid drive, it just tricks the OS. There may not be a simple way to have a defragmenter work on just the physical HD.

I have a Windows 7 Home 64-bit system where the C: drive is a normal NTFS SATA hard drive and the D: drive is a SSD (which has system files on it to speed up the booting times). When I use Defraggler to defrag my C: drive, it gives a warning that it thinks it's a SSD, which would not benefit from defragmenting. Is there a solution to this problem? Analyze shows it's 55% fragmented, so I'd like to do something about that, preferably using Defraggler.
