[gentoo-user] external (NFTS) USB 2TB stick error mount.

[thelma]

I format external nvme SSD (M.2) drive as NTFS on Windows (to store some pictures etc.)
But when I insert the drive on Linux box (it has support for NTFS enabled) I get an error:

 sda: sda1 sda2
 sd 4:0:0:0: [sda] Attached SCSI disk
 ntfs: (device sda2): parse_options(): Unrecognized mount option windows_names.

Stop right there.

You need NVME Support enabled in your kernel.

I DO have NVME support enabled.  My main drive is "nvme"

But I think I need package: 
sys-fs/ntfs3g

Yes, I thought you had this installed.  You'll need it to be able to read and 
write to NTFS.

Please define what you mean by "it has support for NTFS enabled".

Are you running a v5.15 kernel with the new in-tree NTFS driver?

Are you using the ntfs3g FUSE driver?

Are you using the old, read-only NTFS in-tree driver?

I'm using kernel:  5.4.72-gentoo

Under:  File systems:
    DOS/FAT/NT Filesystems:
        <*> MSDOS fs support 
       - <*> VFAT (Windows-95) fs support 
       - <*> NTFS file system support 
       - [*]   NTFS write support   
 After installing sys-fs/ntfs3g
It keeps telling I don't have:
CONFIG_FUSE_FS:	 is not set when it should be.

I think I need to enable:
< > FUSE (Filesystem in Userspace) support

OK, that's what is referred to as the old read-only in-tree driver. It
has had experimental write support for a long time, but people still
call it "the read-only driver". Most people "in the know" seem to
advise that the write support should not be used, and many advise not
using that driver it at all. The ntfs-3g FUSE driver is usually
recommended instead.

> I think I need to enable:

You need that if you want to use the ntfs-3g FUSE driver.

IIRC, the ntfs-3g driver supports a number features that the old
in-tree read-only driver (which you are using) does not. The
"windows_name" option appears to be one of those.

If you want to use the windows_name option, you'll probably have to
disable the in-tree driver and use the ntfs-3g one. It might be
possible to use ntfs-3g without disabling the in-tree driver, but that
sounds like a good way to get confused...

Best to disable the in-kernel write support.  There was a warning it could 
corrupt a fs, unless you were overwriting an existing file with another file 
of exactly the same size.

Yes.

Have a look here, which explains what is needed for ntfs-3g:

https://wiki.gentoo.org/wiki/NTFS

PS.  I recall a case where a corrupted NTFS, I think it was on Win2000, could 
be read by the in-kernel driver.  Neither the native MSWindows OS could read 
it, nor the ntfs-3g.

Because it is read-only for all practical purposes.  Unless there's been a recent improvement its write support technically works, but it can only change the contents of existing files and cannot create new ones.  Works fine for a read-only driver, but not much point to using it unless you're an insane nutjob like me who occasionally needs to boot from NTFS and so needs a driver that can be compiled in.

You've piqued my curiosity -- how do you end up needing to boot from NTFS?

[It never occurred to me that would even be possible.]
