LinuxQuestions.org - Unexpected dd of=file size reported by ls

Hello,
I am running Slack 14.2 x64 and am practically a zero time slacker. The install is very stock; no updates or net connection.

I want to make a 1MiB image file from a section of a 2TB disk with no partition (/dev/sdc) starting at 1.6TiB's. Here is what I have tried:

Code:

bash-4.3# dd if=/dev/sdc of=1600GB-1MiB.dd bs=4096 seek=391130026 count=257

257+0 records in

257+0 records out

1052672 bytes (1.1 MB, 1.0 MiB) copied, 0.201666 s, 5.2 MB/s

bash-4.3# ls -l

total 4948

-rw-r--r-- 1 root root 1602069639168 Feb  3 10:57 1600GB-1MiB.dd

drwxr-xr-x 2 root root          4096 Feb  1 21:43 rawout

-rw-r--r-- 1 root root      2000828 Feb  1 22:19 rawout.dd

-rw-r--r-- 1 root root      2000828 Feb  1 21:54 rawout.zip

-rw-r--r-- 1 root root            2 Jan 31 02:48 test.txt

bash-4.3#

I think 'ls' is saying my outfile size is 1.6TB.
The dd only wrote 1.0 MiB.
This became an issue when I needed to move the file to my 64GB flash drive and 'mv' says the disc is full :(
Anyone see what I did wrong?
