I was cloning my moms 237gb ssd to her new 1tb ssd on her windows 11 S computer using clonezilla and after booting into the 1tb drive it is showing up as 237gb. So I took out my live usb with gparted only to find out the partition used to store the data was indeed taking up 1tb. Is the a reason why it is not showing up as 1tb.
Here are the options I choose to clone the drive if that helps. I also have some screenshots as well.
AFAIK when you clone a drive it will create a partition the same size as the original disk. It doesn't just copy your files, it's a full disk partition clone.
As @breakingcups@lemmy.world said, you'll have to extend the partition to the full drive size in Partition manager (or gparted on a Linux machine).
did you suspend bitlocker or disable & decrypt before cloning? even if you don't specifically enable bitlocker (device encryption), many newer systems enable it by default if the hardware meets certain requirements.. even on base (non pro) editions of windows.
my guess is the software did a sector-by-sector clone of 237gb of encrypted partition it couldn't read and that's what you ended up with on the target disk, regardless of what size it configured in the partition table.
with the original smaller ssd back in the pc: boot up. search for 'device encryption' in the 'settings' app to find where to configure it. if you disable it, it will take a little time to decrypt. reboot afterwords once even if it doesn't 'need to' after the process has completed.
if fast startup is enabled, disable it. if it's enabled, a 'shut down' just logs out and hibernates, and we don't really want to clone a hibernating system. this setting is found in the legacy control panel's (look for 'windows tools' in the full start menu) power options on the same page as 'choose what the power buttons do'. then shut the pc down. you're ready to clone.
