I have a similar question. In my case, if I open Win7 Defragmenter, it says only drives that can be defragmented will be listed. Well my X-25M SSD is listed. So I thought I should check the driver. My driver box is the same as above. If I click Driver Details, I see
In Properties/General the Device Type is "Disk drives" In Properties/Details/Display Name the Value is Disk Drives.
So I am wondering if Win7 is seeing the SSD as an SSD [since it shows up in defrag] and if the correct driver is loaded for the SSD.
