Question Mkntfs : 160GB disk, but 500MB partition?


Hello

I have a 160GB SATA drive available that I'd like to use with a single NTFS partition to back up 44GB of data from another disk.

fdisk let me create a single 160GB partition, but for some reason, after running mkntfs, the partition is only 497MB.

Here's the infos:
Code:
/mnt/sdc5# du -h --max-depth=1 .
...
44G     ./Documents
...

/mnt/sdc5# fdisk -l

#NOTE : sdc = SOURCE
Disk /dev/sdc: 500.1 GB, 500107862016 bytes
255 heads, 63 sectors/track, 60801 cylinders, total 976 773 168 sectors (* 512 = 500GB)
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 4096 bytes
I/O size (minimum/optimal): 4096 bytes / 4096 bytes
Disk identifier: 0x836e6fed

   Device Boot      Start         End      Blocks   Id  System
/dev/sdc1           16065   390716864   195350400    f  W95 Ext'd (LBA)
Partition 1 does not start on physical sector boundary.
/dev/sdc5           16128   390716864   195350368+   7  HPFS/NTFS/exFAT

#NOTE : sdb = TARGET
Disk /dev/sdb: 160.0 GB, 160041885696 bytes
81 heads, 63 sectors/track, 61254 cylinders, total 312581808 sectors (* 512 = 160GB)
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: 0xddadddad

   Device Boot      Start         End      Blocks   Id  System
/dev/sdb1            2048   312581807   156289880    7  HPFS/NTFS/exFAT

/mnt# mkntfs -f /dev/sdb1 -L "Backup Disk E"
Cluster size has been automatically set to 4096 bytes.
Creating NTFS volume structures.
mkntfs completed successfully. Have a nice day.

root@slax:/mnt# df -h /dev/sdb1
Filesystem      Size  Used Avail Use% Mounted on
-               497M     0  497M   0% /dev
Why is the new partition only 497MB?

Thanks for any help.

Edit: Found it. "df" only works on mounted drive.

fdisk prints the size of the partition, df will print the size of the filesystem. Probably you need to reformat it using all the available space. Or just please show us how did you use mkntfs
