This looks more like a strange interaction of your device size (it
claims to have 3902463 sectors) and your partitioning programs which
create partition ending at sector 3902464. Can you send the partition
table you have on the device? E.g:
fdisk /dev/sda
x
p
will print detailed information about the partition table.
n22 ~ # fdisk /dev/sda
The number of cylinders for this disk is set to 1267.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)

I deleted +created the partition both manually and by the digikam
but w/o success...
partition table in linux by fdisk (or some other partitioning program), it
should have created the partition one sector shorter. So please report this
as a bug of the partitioning program. Thanks.
