Windows 10: my 512 gb ssd is showing less c drive capacity

The capacity of C drive is shown as 150 gb, but it actually is 459.33 gb

Drive not showing full capacity after installing image backup to new ssd drive.

Hi,

I upgraded to a bigger ssd drive after the old one became quite full. I used an image backup to do this. All works well after the reinstallation of the new drive. Only problem is my new ssd drive does not show it's full capacity. I still says it is full
in file explorer. Disk management shows the extra space as unallocated. I tried creating a new simple volume but file explorer still does not see it as part of drive C. Still get the message that it is full...(only seeing the old drive size)

How can I get drive C to show it's full capacity? Please help.

 

8GB pendrive shows 7.21 GB as available capacity

Hey Guys,

I have a 8GB Kingston USB Pendrive

First when I inserted the drive into my PC, it showed capacity of 7.26 GB

But after formatting, the capacity shows 7.21 GB

I have tried deleting the partition and creating a new partition using diskpart, but no luck

Why is this so ?

And a 8GB pendrive should actually be having 7.45 GB storage capacity , right ?

Can someone pl help ?

Backing up a Windows system using DD from NVME 512 GB to SSD 500 GB

I used to have two identical 500 GB SSD drives: one inside a laptop, one outside. I would make regular backups using dd from the internal HDD to the external one, as their capacity matched.

I now have a new laptop, which has an NVME drive with (drum roll) 512GB. I am slightly worried about this cosmetic capacity increase crippling my ability to use my perfectly good 500GB SSDs for backups.

I have checked, and dd doesn't seem to care much if it runs out of space in the target file at some point in the copy process - it just stops.

To ensure that I don't end up losing data from the OS drive, I have re-partitioned it to only use 500GB (to match the size of my external drives), leaving 12 GB of unpartitioned space on the NVME.

Question: Will there be any low-level UEFI confusion happening when trying to boot a Windows 10 system image restored to a 512GB NVME from the smaller 500GB SSD drive using dd, if I partition the aforementioned system image to only use 500GB of space on the NVME?

EDIT: Following the advice I have been given, I have reduced my partitions on the source disk (512 GB NVME) to be around 499 GB in total, allowing some space for the partition table. Then I have performed a dd backup to an SSD:

Once completed, gdisk has complained about finding 5 problems.
I have issued a gdisk e command (load main partition table from disk (rebuilding backup)) and then w (write table to disk and exit)

After this the disk would pass verification (v) but I could no longer boot Windows from it. How can I troubleshoot this further and figure out what has gone wrong? I will try to compare gdisk p output for the source NVME drive and the resulting clone SSD to get some clues.

EDIT 2:

Here is comparison of the two partition tables (they match):

However, I am unable to boot from the external drive.
When launching gdisk on the healthy bootable source disk I get:

I don't get this message when running gdisk on the clone. Could it be that in reading the partition table incorrectly gdisk is somehow corrupting it?

Could it be the use of Bitlocker that is making the GPT table 'odd'? I had no issues with Truecrypt previously..

EDIT 3:

I am typing this from an OS running on a successfully cloned drive!
The recommendation from the accepted answer has worked. To summarise:

• Reduce the used space on the 512 GB source media, by shrinking the last partition by a bit more than 12 GB (to allow for the partition table copy to reside at the end of the disk)
  
• Perform a dd clone from 512 GB source media to the smaller 500 GB disk.
  
• Run gdisk and select d option to rebuild the backup header
  

After these manipulations I have been able to successfully use the drive.
