4Tb USB Disk formatted at 2Tb #522

Closed ik0api closed 4 years ago

ik0api commented 4 years ago

When I request formatting a 4Tb USB external disk Syncloud announces it will format at 2Tb. And it does it, leaving 1,7 unused and unpartitioned.

Tried with a WD Elements and a Maxtor M3

In the past I was able to format at 4Tb regularly, with the same RPI4 4Gb

This is not good and it is related to MBR (32bit) limitation and we should switch to GPT (64bit). https://en.wikipedia.org/wiki/GUID_Partition_Table#History

There is a test version, could you try?

snap refresh platform --channel=master

If you format the disk it should take the full capacity. Obviously you will lose all the data on it!

mmh... I have very little experience with Linux, that's why I'm a happy user of the great Syncloud! I would format a new disk at 4Tb then transfer the folders of the now-2Tb one. Would it work?

cyberb commented 4 years ago

Yes

Have you tried?

ik0api commented 4 years ago

Not yet. I'm very basic on Linux, I need to learn how to move files between disks and then I'll try

I successfully upgraded to a 12Tb WD USB while keeping all my files and settings!

Firstly, I saved an image of the 2Tb partition with Aomei Backupper Free (for Windows), which can handle EXT4. Also for backup. Then I cloned the 2Tb MBR partition to the new 12Tb disk (originally NTFS) with Aomei Backupper Free Then I connected the 12Tb disk to an RPI2 with Noobs (Debian), installed Gparted and expanded the partition from 2Tb to the full 12 Tb space. Gparted automatically converted to GPT, I think.

I connected the new disk to my Syncloud RPI4 and now have all my files, all apps and all settings running perfectly.

Note: I didn't set Nextcloud to encrypt my files, don't know wether this can trouble the HD switch.
