NTFS disk not recognized

[Tater]

Hi,

First off, great job on the software. It's been a treat being able to use the pi as a server.

I have a problem that I need some help with. I'm somewhat new to linux so perhaps it's my lack of experience that's the problem.

I have two usb disks connected to the raspberry pi.
One is formatted as ext4 and is up and running with no problems on the Pi.
The 2nd disk is formated as NTFS and i can't get the Pi to recognize it.
If I format it as ext4, the Pi is able to recognize it but not when its formatted as NTFS.

I have other windows computers in the house and would like to keep it formatted as NTFS for compatibility.

What do I need to do differently for the NTFS drive to work?

Thanks,
Tater

Hi Tater,

only ext3/4 (or FAT32) USB partition are mounted as internal disk (listed in the disks setup menu).

If you use NTFS as fs, the related disk should be listed in the USB disks menu and a global share is created.

Hi Jocko,

Thanks for your help but I'm not sure I understand.

Under Disk Setup ->Setup in the "manage disks and volumes" section, there are two disks listed.
"Single" with 2.3GB I assume to be the SD card.
"USB-A" with 465GB is my Ext4 disk.
The NTFS disk is not listed.

Under Disk Setup->USB Disks at the top under "USB storage" there is nothing listed.
The NTFS disk is not there. Should it be?

Both disks are connected to the same powered hub.

Hi Tater

Under Disk Setup ->Setup in the "manage disks and volumes" section, there are two disks listed.
"Single" with 2.3GB I assume to be the SD card.
"USB-A" with 465GB is my Ext4 disk.
The NTFS disk is not listed.

That is ok

Under Disk Setup->USB Disks at the top under "USB storage" there is nothing listed.

Yes, it should. You must enable the debug mode to trace the plugin event:
a/ unplug your USB hub
b/ Use this url:http://yournasname/.status/nas-status.php and start the debug mode.
c/ plug in again your hub
d/ check option 'Get a full Log and export it

Now you can stop the debug mode and post here the Log sections:
# Mount table
# syslog file

And if you can open a shell console, post the outputs:

Code: Select all

 ls /sys/class/block/sd*

and

Code: Select all

fdisk -l

not sure if this is normal but the begining of the debug file had this warning:

Warning! Secondary partition table overlaps the last partition by
33 blocks!
You will need to delete this partition or resize it in another utility.

Let me know if there is any other information you need.
Thank you again for your help.

Hi Tater,

Warning! Secondary partition table overlaps the last partition by
33 blocks!
You will need to delete this partition or resize it in another utility.

It is not clear for me what is the related disk.

So first, I think that you will get also this warning with this command from a shell console

Code: Select all

gdisk /dev/sda

(enter q to exit) repeat with sdb. You should read this warning from one of both output.

I found this from Internet

When you convert your disk from MBR to GPT, You may see this warning which prevent you from converting:

Warning! Secondary partition table overlaps the last partition by 33 blocks!

It is because GPT needs to store a backup copy in the last 33 sectors of the disk. So you need to resize your last partition to make at least 33 sectors free space. I have tried, and 1 MiB is free space is enough. (1 MiB unallocated space)

It runs right up to the very last sector of the disk, which is not allowed since the GPT stores a backup copy in the last 33 sectors of the disk. If there isn’t anything important on the partition, you should be able to just delete it in gdisk.

Do you try to convert a disk from MBR to GPT ?

[Jocko]

Another explanation to detect what is wrong.

On each disk, you have a primary partition

Code: Select all

gdisk /dev/sdb

Enter 'r' and 'o' then you get this output

Code: Select all

Disk size is 3987456 sectors (1.9 GiB)
MBR disk identifier: 0x00000000
MBR partitions:

Number  Boot  Start Sector   End Sector   Status      Code
   1                     1      3987455   primary     0xEE

=> Note 3987455 In my example
Now print the partition => Enter 'p' if you are still in the gdisk interface and the output is

Code: Select all

Number  Start (sector)    End (sector)  Size       Code  Name
   1            2048         3987422   1.9 GiB     8300  Linux filesystem

So the last sector of my partition is 3987422.

=>3987422 + 33 = 3987455 :thumbup As this disk contains a GPT table is ok

But in a 2d example, with a not GPT table I have:

Code: Select all

gdisk /dev/sda

a Primary table

Code: Select all

Number  Boot  Start Sector   End Sector   Status      Code
   1                     1   3907029167   primary     0xEE


and in my partition table

Code: Select all

   8         5735268      3907024064   1.8 TiB     8300  Linux filesystem


The last used sector is 3907024064 and then I have only 3 free sectors. So if I try to convert my MBR table to a GPT table I would get an error.

So I assume that with your used partition utility (GPT, GPART,...) on a disk, the primary table is set as a GPT table but without enough free sectors at the end
