I am having a problem installing Gparted. The software centre seems to install it two times.
I get this error message when I try to use what’s installed.
/dev/sdb contains GPT signatures, indicating that it has a GPT table. However, it does not have a valid fake msdos partition table, as it should. Perhaps it was corrupted -- possibly by a program that doesn't understand GPT partition tables. Or perhaps you deleted the GPT table, and are now using an msdos partition table. Is this a GPT partition table?
The message is pretty explicit. Is /dev/sdb a "real" disk you want to investigate, or a USB you're using for gparted. If the latter reply either y or n, and ignore that device. Seems common with hybrid iso's I have dd'd to a USB.
If it is a "real" disk, you have a real problem - give us more detail on how it got in that state.
If you would like to check on the health of your HDD you can use smartmontools.
The drive needs to support SMART for information to be available.
If it's not installed use APT to install it.
Code:
sudo smartctl -a /dev/sda
Like JohnVV said it's better to run G-parted with a Live CD.
I've seen a lot of member say that they have had more success that way.
