Hi, Using Arch and the latest kernel : 5.16.5-arch1-1 I am getting a really long mount time using ntfs3 ( about 50 seconds ) for this ntfs partition : ntfsresize -i /dev/sda2 ntfsresize v2021.8.22 (libntfs-3g) Device name : /dev/sda2 NTFS volume version: 3.1 Cluster size : 4096 bytes Current volume size: 6001039241728 bytes (6001040 MB) Current device size: 6001039245312 bytes (6001040 MB) Checking filesystem consistency ... 100.00 percent completed Accounting clusters ... Space in use : 5063774 MB (84.4%) Collecting resizing constraints ... You might resize at 5063773290496 bytes or 5063774 MB (freeing 937266 MB). Please make a test run using both the -n and -s options before real resizing! This is an external disk attached over USB 2.0 but for the same partition I get a much faster mount time of less than 3 seconds using ntf-3g. Connecting the drive over USB 3.0 results in a faster mount but still slower than with ntfs-3g on USB 2.0 If you need any further information let me know. Thank you
