Wipe 2TB disk
I recently purchased a 2 TB hard drive, but at the moment only 20 percent of its space is in use. It takes a lot of time to get this drive wiped. Is there any way to save my time when performing an 'Entire disk' erasing task?
I would recommend you to cancel this operation and do as following instead if you have partitioned the 2TB hard drive:
1. Click Erase entire drive instead in ByebyeData Eraser after canceled erasing the entire disk.
2. Click the drive contains files and then select the fast overwriting methods, which would be the 'Simple overwrite methods', then click Erase Now and confirm.
If you used 20% space is not from a particular drive but distributed into many other partitions, which mean each partition has a small amount of usage, the method we provide above is sufficient. Try the alternative way instead:
1. Press Windows + R to open the run dialog, and type 'diskmgmt.msc' to open Windows Disk management, this shortcut will work on Windows 7, 8, and Windows 10, (haven't tested on Windows Vista and XP).
2. In the disk map, right-click on the partition you had used and choose Shrink Volume, follow the wizard and shrink as much as you can to create unallocated space, then you left all the used space as a partition.
3. Repeat the Shrink step on other partitions if they have some used space.
4. Then open Windows file explorer (Windows + E) and press Shift+Delete to delete all the files on them.
4. Run ByebyeData Eraser and click 'Erase free space', then our program will load all the partitions and unallocated space, just select all the partitions, don't click on the unallocated space (No need to wipe them) and then select fast wiping methods, then click Erase Now and confirm it.
When you don't want to shrink partition separate used space and free space, you can simply use the Erase files and folders function if most of the rest space is free space.
