Without knowing details of your Computer's hardware specification, anything anyone is trying to answer will be purely on guesswork. Since you have hinted about your Optical drives- "DVD/DVDRW drives ", I presume you are referring to your Hard disk drive when you said about Missing D drive icon. If you have only one HDD then your mention of "D-drive" must be your second partition on the single HDD ( HDD-0 or HDD-1 depending upon the MoBo BIOS designation).
One way to get a little more details about your Computer's Hard disk drives is to use the
Computer Management Snap-in tool.
- Right-click Computer
- Click on Manage from the drop-down contextmenu
- In the Left Pane of Computer management window that opens, scroll down to Storage and click it to expand it and then click on Disk Management
- Now look at the Right pane and locate at the bottom of the divided pane the Disks and at the top box, the Volumes or the partitions with their drive letters. like C, D E F or whatever
- The bottom box shows your Disk numbers like 0 , 1 etc and your Optical drives like D or E or whatever alphabets the system has designated them to have and USB Flash drives or Hard drives if you have connected them to your machine.
Normally, if you have partitioned the HDD and designated a drive letter for each partition, you should see them when you click open
Computer. If it is
unallocated there won't be a drive letter and
you won't see that in the
Explorer view .
My assumption is that when you installed Win 7 either you used the whole disk as a single partition (or drive) or carved out a C: drive leaving the rest as
Unallocated yet to be partitioned and formatted
I hope the above steps will help you solve the mystery of the missing D drive
