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.
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.
you may want to re-enable the device encryption, especially if it's a laptop that is taken out of the house regularly or the pc is used to store financial or personal documents.
if you do: after it's done, log into her microsoft account (the one tied to her windows login) and find the bitlocker recovery key (probably under devices). print it out or write it down (legibly, and double and triple checking). store it in a safe and secure place you won't forget about.
