Regarding deleting the D: recovery partition. At 15.59 GB it's unlikely to contain anything other than the recovery image, Toshiba's OEM recovery image for my (as was) Win7 laptop was 13GB. On my Toshiba there was also a D: recovery drive, though unlike your system, the C: and D: partitions were each about half the disk. The actual recovery image was in a HDDRecovery folder on D:, the rest of the free space being intended for user data. I've deleted my HDDRecovery folder* and now use the free space for other things.
* actually, I still have a system image of the original HDD, just in case.
I have already bought this backup program, and cannot afford to buy another backup program.
That is the one yes , it's always a good idea to right click on all downloads and have your virus and malware scanner scan it before you double click it to Run the installer.
and +1 from me on Macrium too great free program
BTW.....Some backup programs like the built in one in win10 will backup ANYTHING they think is necessary to do a complete Restore of Windows, it is why I now use Macrium actually .
That new tutorial looks great too , didn't know it was there...
"At this point I just want to know how to delete the information on that D drive or be able to get rid of D drive and incorporated it with my C drive"
Easy way to delete the info is just r-click the drive and Format. This will wipe all info in seconds and clear the space for re-use. Use a partition manager, as recommended, if you want to merge with C.
PS; I did a similar thing. I never wanted to go back to orig 8.1 system and since I create images with Acronis, I formatted the D drive and used the space to put copies of all install programs on it. This is useful because if I do a clean install, the D drive is left intact to quickly re-install all programs to the clean system. Just another option to consider. Good Luck
Sonjstar This really is the quickest way to delete the partition and get your space back. If the Disk Management should balk for some reason, Minitool will do the job (yes, you downloaded the correct one).
Not to belabor, but the backup software that came with your machine (and you update for $$) is honestly not the best move going forward. When you get the partition issue straightened out, you should take the time to investigate the Macrium backup system. It is far superior (no, I don't work for them ). The built-in Windows backup system is functional, but archaic and incredibly inflexible. Just trying to give you some honest advice, along with all the others here giving honest advice. The choice is yours to make. All are here to help.
