Title: Why I can't mount a usb partition?
Post by: gam 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
Does it work like this:

Code: [Select]

sudo ntfs-3g /dev/sdb1 /mnt/sdb1

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.

Title: Re: Why I can't mount a usb partition?
Post by: gam on June 05, 2021, 12:48:45 AM

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?

Post by: Juanito on June 05, 2021, 02:14:12 AM

What does this give:

Code: [Select]

$ fdisk -l
To check if ntfs-3g is loaded:

Code: [Select]

$ tce-status -i | grep ntfs

Title: Re: Why I can't mount a usb partition?
Post by: gam on June 05, 2021, 02:44:12 AM

My command:

Code: [Select]

tc@box:~$  tce-status -i | grep ntfs
tc@box:~$Nothing happened

Title: Re: Why I can't mount a usb partition?

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

This happens with mbr because it cannot distinguish between exfat/hpfs/ntfs - as long as you formatted the partition for ntfs, you should be able to mount it.

Hello Forum,

TRied to remember using that 3Gntfs extension here.

i remember
1) booting  TCL
2) loading the 3gntfs extension from the repo.
3) made sure no partitions or drives were mounted.
4) my drive showed 4 parts......
5) get the correct execution of the command to run the
extension in 2) above .......
give it the correct argument (flag)
of the correct "fully qualified environment drive path"  to the named partition where my TCL stuff is.....  (it is an NTFS partition)

6) it would mount and PRIME that work in 5) above..... then it would READ extensions from that location in 5) and load them...... if i told it to.

C

ps...but it was not a USB drive....it was a regular SSD drive.

.....is it possible the USB drive has not been correctly configured
as a whole NTFS drive with maybe some partitions inside that Larger whole partition....?

Hello Foum and OP,

Great that it is solved.

.. . .  .there is great "worth" in knowing how to start--up systems to get useful "computing operation" from the equipment.....

Yes.

Thx
