ntfs drive won't mount

[new666uk]

Hi,

Objective: New Linux build on a new SSD and re-using the 3x HDD from my Windows HTPC which contain movie / music / TV content. One of the ntfs drives will not mount.
Deviation: drive will not mount, other ntfs drives have successfully mounted

The drive shows up in fdisk

Disk model: ST4000DM004-2CV1
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 4096 bytes
I/O size (minimum/optimal): 4096 bytes / 4096 bytes
Disklabel type: gpt
Disk identifier: 81E0FD96-ED59-11E7-9819-D43D7E9DDC22

Device Start End Sectors SizeType
/dev/sdc1 34 32801 32768 16M Microsoft reserved
/dev/sdc2 34816 7814035455 7814000640 3.6T Microsoft Storage Spaces

Partition 1 does not start on physical sector boundary.

and in partition manager but as an unknown type:



but I've been unable to successfully mount it.

Attempts so far:

sudo mkdir /mnt/Movies2
sudo mount /sdc2 /mnt/Movies2

This resulted in an NFTS signature missing error with an invalid argument I tried mounting sdc, sdc1 and sdc2.

Running

lsblk -o name,size,fstype

I can see sdc is missing the type.




Question - is this recoverable within a Linux environment or am I better rebuilding the device back with the original Win10 c: drive and changing the storage drive in there?

thank you!

you can inspect and change the partition type codes in cases where they have gotten changed somehow and linux no longer recognizes them... from my notes

#Run fdisk on the appropriate disk, for example without partition designation

sudo fdisk /dev/sdc

#Press t to change the type of a partition. If there are several, you will be asked which one you want to change:
#Partition number (1,2, default 2):
#If there’s only one, fdisk will tell you it’s automatically selecting it:

Selected partition 1

#Once the partition is selected, fdisk will ask what type you want:
#Partition type (type L to list all types):

#Enter the number here. Press p to check the result,
#then w to write it to disk if the changes are OK or q to quit without saving.
#This won’t touch the contents of the partition, you won’t lose any data.​

you probably want them to be type 07

I seriously doubt you need to mess with the partition type.

1. This

   sudo mount /sdc2 /mnt/Movies2

   is incorrect. It would need to be this:

   sudo mount /dev/sdc2 /mnt/Movies2

   Note the added "/dev" in front of /sdc2.
2. If this still doesn't work, run "ntfsfix" on /dev/sdc2
3. If you still have Windows, boot to it and run Windows chkdsk on that file system.
4. If 1,2 and 3 fail. You may need to dig deeper..

EDIT: You also need to verify that the file system is not encrypted. If it is, that would explain why KDE Partition Manager says it's unknown.

Another thing that can cause this is shutting down Windows with fast start enabled.

I will say that "Microsoft Storage Spaces" is a new one for me. Usually its "Microsoft basic data" but maybe the former is for non-bootable ntfs file systems while the latter is for the OS file systems
