I have an external 1Tb harddisk which due to some reason was showing following under df -i

Filesystem        Inodes   IUsed     IFree IUse% Mounted on
/dev/sdb1              0       0         0     - /media/Transcend1T

But it has lots of free space remaining. So I took its backup and formatted it with disc utility in Ubuntu. But even after that Inodes still remain zero (it shows same output on df -i).

Is this a problem? Can some filesystems always have zero inodes?

Below is the output of fdisk -l on formatted disk.

Disk /dev/sdb: 1000.2 GB, 1000204886016 bytes
255 heads, 63 sectors/track, 121601 cylinders, total 1953525168 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x0ff10b79

   Device Boot      Start         End      Blocks   Id  System
/dev/sdb1   *          64  1953520063   976760000    c  W95 FAT32 (LBA)

Formatting screenshot. I first unmount the HDD and then click the Format Volume button shown. I have also clicked Check filesystem but it didn't fix the problem. enter image description here

Exactly how are you formatting the disk? (i.e. screenshot of commands used, which software are you using with precise directions, etc) Perhaps you are making a minor mistake that we will notice. –  David Sep 19 '13 at 4:06
    
@David added screenshot. –  user13107 Sep 19 '13 at 4:13
    
Does this method of adding a disk usually work for you, or is this the first time you have needed to? –  David Sep 19 '13 at 4:24
    
@David yea, usually it works. –  user13107 Sep 19 '13 at 5:23

The filesystem you are using as an example is FAT based; it does not have inodes.

Is this a problem?

no

Can some filesystems always have zero inodes?

yes (but never say never)

I checked a fat filesystem myself and df reports no inodes, though I have been successfully using it (and it is currently holding 10GB of data).
