I buy new hard disk, when I copy my old 500GB to 1TB, suddenly disk usage not equal, 1TB use more space, how come?
Drive quickly full, files on 1T use so much space then 500G

that is due to the difference in the sector cluster size.
https://support.microsoft.com/en-us/kb/140365 Open up command prompt as administrator. Then run the command: chkdsk <drive> Example: chkdsk c: Output will be as below: CODE Windows has scanned the file system and found no problems. No further action is required. 107217919 KB total disk space. 88190304 KB in 284220 files. 183872 KB in 49629 indexes. 0 KB in bad sectors. 671595 KB in use by the system. 65536 KB occupied by the log file. 18172148 KB available on disk. 4096 bytes in each allocation unit. 26804479 total allocation units on disk. 4543037 allocation units available on disk. Look at 4096 bytes in each allocation unit. This part will be cluster size. It should be 4096 bytes by default. So maybe you somehow formatted it to 8192 or something.

QUOTE(Anime4000 @ Dec 5 2016, 06:05 PM) This shows that each file on the drive would take up a minimum of 128kb of space. If your drive have plenty of small files, you will end up with a lot of wasted space. You will need to reformat the drive in order to change that value. How did you end up with the drive bring formatted using the exFat filesystem? |
