Title:
fuseblk corruption of NTFS drives
Status in fuse3 package in Ubuntu:
New
Bug description:
NTFS SSD (or a USB external NTFS drive) - Used primarily by Ubuntu 22.04.5 but also used by Win10.
(I take Win10 as the reference design implementation for NTFS so I use it as a double check of my NTFS drives for integrity; so every so often I do a Win10 Tools check of NTFS drives which sometimes leads to having to repair them, occasionally via a Win10 reboot repair procedure).
The following text is a Win10 App Event Log of one such repair to an
SSD NTFS drive used by Ubuntu 22.04.5 via fuseblk. (I have the ntfs3
device driver blacklisted as that appears to be substantially worse
for generating NTFS errors).
Checking file system on D:
The type of the file system is NTFS.
Volume label is SSD-480GB.
The volume is dirty.
