Your D: Drive is the Recovery Partition, that the Manufacturer put there, for your computer to put it back to factory settings in case of System Crash.
It is not for you to save anything to; and it is not to compress and/or Index, or have System Restore turned on for it.
Whatever you have installed or saved to D:, DELETE it very carefully and leave it alone.
You are supposed to have made Recovery disks from D:, in case of Hard Drive failure.
Ask the Manufacturer how to make them
