Hi there
What's wrong with CMD mode
1) DISKPART
2) LIST DISK select the disk you wnt to process
3) SELECT DISK n (n = the disk you want to process).
4) CLEAN
5) (optional Convert to GPT -- I always use GPT disks these days - CONVERT GPT)
6) EXIT
(at 5 if you still want to stay with MBR just CREATE PARTITION PRIMARY or do it in Windows in CTRL panel disk management as below).
Now go into ctrl panel==>admin tools=>computer management==>disk management
Create partition(s) at will.
the CLEAN command removes everything off the disk ==> you don't need any 3rd party stuff for this.
NOTE : BACKUP ANY DATA BEFORE DOING THIS - use TREESIZE (free) which is a bit easier to see what's on your disk(s) than the other program WIndir referred to in the previous post. Screenshot enc .
TreeSize Free - Quickly Scan Directory Sizes and Find Space Hogs
Now clean and convert disk.
GPT disks will work on UEFI or Non UEFI computers
- however GPT as a BOOT drive will only work on UEFI computers -- you don't have to have protected boot mode set but the BIOS must be UEFI / EFI enabled.
GPT drives can access > 2 TB partitions and the 4 primary partition restriction you have with MBR disks is GONE !! so you can have as many partitions as you like.
(External devices can also be converted into GPT drives too).
