USB HDD denied access
Hi I have connected a USB drive formated in NTFS to my NAS. There are several folders on it which I uses with PLEX Server. I have ejected this device several times and also rebooted with the USB d...
It isn't because of NTFS compatibility. FAT32 wouldn't have helped (and FAT32 doesn't handle large files, so I personally don't use it).
I don't know exactly what happened in your case, but it is related to USB, not the file system. Linux support for USB drives isn't as good as Windows - you always need to be careful to remove the drive via the GUI before disconnecting it. And even if you do that, there still might be some times when the file system gets mildly corrupted (power failure for instance).
In any event, the symptom you saw (drive became read-only) almost always means that (one way or another) the USB drive was flagged as being in an inconsistent state (the disk volume's "dirty bit" was set). The NAS puts it into read-only mode because writing to the drive potentially would do more damage. Windows will offer to repair. Usually no harm results, but it is wise to have a backup the data on that drive.
