How to understand why mkdir does not allow you to create a folder with a certain name?

Question

linux

There is a hard drive (8TB, NTFS formatted) connected via USB to the Ubuntu machine. Files were copied to the disk, the computer hung and was restarted with the button.
After the system boots, I cannot create a folder named "BAKERY_005" on the drive:

mkdir: cannot create directory ‘BAKERY_005’: Input/output error

I can create "BAKERY_05" or "BAKERY_0055" (and probably any others), but "BAKERY_005" I can't. Tell me how to fix it, in which direction to dig?

Answer 1

fsck

Answer 2

Try to create with this name on a different path.
If you manage to create it in a different way, but it doesn’t work out where it was, then it looks like you broke the file system a little.
