Can't erase my hard drive...Please help!!

OK, I've been working on computers for many years, and have erased and reformated Hard drives more times than I can count. However, I'm in the process of upgrading right now, and wanted to erase and reformat before I put the HD in my new system. I usually will erase my HD's with Active Killdisk. For some reason, it will not work with this HD. Every time I try to run Killdisk, it starts to run and then brings me back to the Killdisk menu scxreen. I thought maybe it was a bad CD burn, so I burned a second copy and the same thing happened! Anyone have a clue as to why this won't work? Also, any alternative suggestions to quickly erase this Hard drive? Not that it really matters, but this HD will be used exclusively for storage from now on. My OS and apps will be on my new Raptor.

 

hard drive full, but can<t find the item to erase

Windows 10 has the option to change the storage location. We suggest that you change the storage location so you can still use your hard drive instead of using the SSD. Kindly follow the steps below on how to change the storage location:

• On the Search bar, type in storage and select the top most result.
• On the Storage screen, change the location of each options to your desired hard drive. The files will now be saved on the specific hard drive.
