Why I can't mount a usb partition?
« on: June 04, 2021, 08:26:29 AM »
I made a Grub2 bootable usb, with:
-sdb1(HPFS/NTFS) has vmlinux and core.gz
-sdb2 (FAT32) is efi boot partition and contain ntfs-3g.tcz and dependencies.
Grub2 boot the OS very well (I didn't load ntfs-3g, system seemed to select HPFS file system?). But I can't mount /sdb1 to /mnt, although I loaded ntfs-3g,
Code: [Select]
mount: invalid argument

Hi gam
You also need to post the command you executed that produced that error message.

What mount command are you using?

Why not use a linux filesystem?

my terminal

it seems that ntfs-3g only works internally in sdb2 partition, ntfs-3g doesn't work in the whole usb drive (include sdb1 (HPFS/NTFS) partition)?

Hi gam
Do your partitions exist in the  /dev  directory:
Code: [Select]
ls -l /dev/sdb*

Hi gam
Matbe the problem is loading  ntfs-3g  after the device was plugged in. Run this command:
Code: [Select]
sudo udevadm triggerthen see if it mounts.

It still unmount
Code: [Select]
$ sudo udevadm trigger
$ sudo mount -t ntfs-3g /dev/sdb1 /mnt/sdb1
mount: mounting /dev/sdb1 on /mnt/sdb1 failed: No such device

/dev/sdb1 doesn't appear after
Code: [Select]
$ df -aTh
I think ntfs-3g isn't loaded, because:
Code: [Select]
$ sudo ntfs-3g /dev/sdb1 /mnt/sdb1
sudo: ntfs-3g: command not found

Do I need install ntfsprogs.tcz? Or add ntfs-3g in grub.cfg?

What does this give:
Code: [Select]
$ fdisk -l
To check if ntfs-3g is loaded:
Code: [Select]
$ tce-status -i | grep ntfs

If nothing happened then ntfs-3g is not loaded.

Try:
Code: [Select]
$ tce-load -i ntfs-3g
$ tce-status -i | grep ntfs

Hi gam
After you run  tce-load -i ntfs-3g.tcz  try this:
Code: [Select]
hash
sudo ntfs-3g /dev/sdb1 /mnt/sdb1

Why Tinycore can't mount HPFS filesystem? Because sdb1 is HPFS/NTFS
