Cannot mount ntfs internal partition

benRocks · 2020-11-14 11:13:15

Hi Forum,
I've got a quite strange problem here when trying to mount NTFS partition data. I have a Win10 HP laptop, UEFI boot and internal SSD NVME volume. Here are few sysinfo

Arch is installed on external USB3 SSD disk, boot from EFI and I can regularly see Win Partitions /dev/nvme0n1p3 is where my data are, I've installed ntfs and ntfs-3g utils but a simple

mount -t ntfs -o ro /dev/nvme0n1p3 /mnt/windows/
NTFS signature is missing.
Failed to mount '/dev/nvme0n1p3': Invalid argument
The device '/dev/nvme0n1p3' doesn't seem to have a valid NTFS.
Maybe the wrong device is used? Or the whole disk instead of a
partition (e.g. /dev/sda, not /dev/sda1)? Or the other way around?

Cannot mount that partition.

I have:
- disabled fastboot
- rebooted windows (instead of a shutdown)
- chkdsk /f in order to avoid mistakes on the partition
but none of them produced a different output from what I've reported above

Formatting the partition is not an option, I can change something (if required) but I need to preserve internal Win10 installation, what am I missing ? Is there something wrong in the partition or HW ? I'm using a UEFI system and I've booted arch in EFI mode (not legacy BIOS) but I still cannot reach that Microsoft basic data part that seems to be invalid even if Win10 regularly boots it (still, no fast boot or hybernate modes)

Can someone please address me to the right solution for it ?
Thank you in advance for your kind reply

Ben

Even more:
I've also tried to mount that with PARTUUID instead of partition name but I always see the NTFS signature error

Are you sure it's ntfs and not exfat? Does mount work without specifying a filesystem type?
When you boot into Windows, what filesystem is shown for nvme0n1p3?
If it is ntfs I think you should expect to see a ntfs flag shown against nvme0n1p3 in your "lsblk -f" output.
Do you have bitlocker enabled under Windows?

sudo file -s /dev/nvme0n1p3

Forgot to mention I've already checked bitlocker and windows tells me it's disabled
I'd like to provide information you required so here's something more:

Each operation has been executed with root privileges in order to skip permission troubles.
I've tried mounting partition as exfat but from Windows disk manager is clearly marked as NTFS even if I seriously don't know what "data" means (from "file-s" command).

This is the first time I'm having problems with ntfs partitions and EFI, but it's even the first time I'm doing it with a nvme device (SK hynix BC511 HFM256GDJTNI-82A0A) and a laptop, HP is not properly known for open source transparency on laptops (AMD® Ryzen 5 3500u with radeon vega mobile gfx × 8).

You could try https://aur.archlinux.org/packages/dislocker/ to see whether there's a bitlocker encoded partition…
