If you’re still using a data drive formatted as NTFS, and you’re not using Windows anymore, it’s best to change the filesystem.
Linux NTFS drivers are pretty good, but it’s still reverse engineering a proprietary filesystem. Sometimes it misbehaves.
If you’re using something like ExFAT then ignore me.
Depending on the amount of data, you might be able to shrink the existing NTFS partition, create a partition next to it of the proper filesystem type, move the data between the partitions, delete the NTFS partition, and expand the replacement.
But I wouldn’t attempt that on ant data you care about unless you have backups. I’ve done things like that a lot working in the tech industry, and sometimes things just break.
