GParted is very easy to use. I was impressed with this app when I started to use it. It is perfect in modifying partitions!
Oddly slow and weak in features.
I have yet to use this for the following reason: I downloaded the Live CD and it would not boot. This is caused by the fact that the ISO I downloaded was set up for EFI booting and not bios booting. It would save time and resources if the developers would add either MBR or EFI_GPT to the end of the file name so that users know which Live CD ISO will work on their equipment. EFI_GPT will not boot on a BIOS MBR system so don't say that it will. All one need to is do a web search "computer won't boot with 4T usb drive connected" and you will see the issue. It turns out that BIOS systems that look for the MBR, and do not know anything about GPT drives, will crash when a GPT drive that does not have an MBR connected. Two systems I have wont' go past the "enter setup boot menu" screen. In fact, with a GPT drive connected to the USB port, once the computer reaches the aforementioned screen, it will not respond to any key command, not even the ole CTRL+ALT+DEL reboot sequence. Take care.
