While you use GParted to resize a partition, you may receive the error that the current NTFS volume size is bigger than the device size. This error offten happens when shrink or extend partition with NTFS file system.
This error occurred when you tried to resize ntfs partition was first reported in GParted Live 0.4.8. This version of GParted has a bug that it does not work well with the NTFS file system. It also might cause data corruption while managing to resize EXT4 partition. The basic reason behind this problem was possibly that the program failed to update the Linux kernel while using Gparted to resize partition.
This problem was only happened in a few old versions of Gparted, so you can use the latset version of GParted to avoid this problem or try a free Gparted alternative, AOMEI Partition Assistant Standard. it is a free partition manager software that helps you to resize NTFS or FAT32 partitions without losing data. You can merge two adjacent partitions into one or add nonadjacent unallocated space into an existing partition by using the Merge Partitions Feature. It allows you to create bootable USB drive or CD/DVD, so you can manage your disks and partition even if there is no system on your hard drive. It support many file systems including NTFS, FAT32/FAT16/FAT12, exFAT/ReFS, and Ext2/Ext3/Ext4.
