gparted - Disk size smaller after creating partition table + old data gone

  • 772

I had the same issue as the guy posting on Trouble creating 3TB ext4 partition due to msdos-partition-table-imposed error

The new 6TB drive I got was only issues 2TB by Microsoft so I booted into gparted "Device->Create Partition Table and select "gpt" from the list." I then booted back up into Windows and G: drive was no longer mounted. I deleted disk0 and recreated it inside Windows disk management however as you can see in the screenshot below the disk size is only 5589GB. Should it be more?

I did use about 300GB of data before doing this and I would like to recover that data but both Windows and gparted can't detect anything more than the 5589GB.

    This is due to the 1000 vs. 1024 bytes problem.

    You see, assuming 1024, a 6TB drive can hold 6.6E12 bytes. However, assuming 1000, it can hold 6E12 bytes.

    The difference between the two is 6E11 bytes, or 559GB. Thus, your reported capacity is 559GB less than what you think it should be.
