[SOLVED] Setting write permissions on Windows share from linux

ihowarth · 08-03-2020, 03:32 PM

I want to occasionally access files on a Windows 10 machine from a linux box, with full rw permissions. I've followed this "how-to": https://www.howtogeek.com/176471/ and I'm mounting the Windows disk manually, with this basic incantation:

mount //Win10box/Win10disk -o username=windowsID /linuxmount

which works just dandy -- except that the windows disk is read-only. "Extensive research" (an hour googling, including some promising-looking posts here that didn't help, at least not at my pay grade) has suggested all kinds of options, but none of them seem to make the slightest difference; e.g.,

mount //Win10box/Win10disk -o noperm,dir_mode=0777,file_mode=0777 username=windowsID /linuxmount

mounts the disk without error, and the protections show up as drwxrwxrwx -- but i still can't write to the disk. I've double-checked that full rw permissions are set on the Win10 side...and am now stuck... Probably something "obvious", but anyone see what i'm missing here?
Thanks

try running fsck on it or doing a disk check/clean from windows ( can't help with the windows commands )

NTFS file systems do not understand Linux permissions.

Thanks, both.

Keith, don't think it's a hardware issue (as i infer you're suggesting), there are two separate HDD on the remote Windows box and the issues are the same for both of them (and they're each only a few weeks old).

Frank, yep, learned that the hard way! So, how then to write to the Windows disk? I've double-checked on the Win box, "everyone" appears to have read/write access on the share....just that, in practice, i don't

probably a comma?

you may need to check the logs.

Not an 'issue' but if it wasn't unmounted properly mount will apparently mount it r/w but the underlying fs will be read only.
It does no harm to do an fsck

Well, i'm kinda embarrassed to admit that i deleted everything on the windows side, redid the shares, and...it now works. I have no idea what's changed (nothing at all as far as i can see, but that's obviously not a reflection of reality, just my perception). Sorry to have wasted folks time on here
