problem z obrazem partycji za pomocą dd

[freerider]

Witam.
Mam następujący problem ze zrobieniem obrazu partycji za pomocą dd.

po wykonaniu dd if=/dev/sda2 of=/home/freerider/obraz.img zwraca następujący błąd:

root@niewinny:~# dd if=/dev/sda2 of=/home/freerider/obraz.img
dd: czytanie `/dev/sda2': Błąd wejścia/wyjścia
6302728+0 przeczytanych recordów
6302728+0 zapisanych recordów
skopiowane 3226996736 bajtów (3,2 GB), 207,391 s, 15,6 MB/s

jakim narzędziem bym nie próbował dd czy gzipem
gzip -c /dev/sda2 > /home/freerider/obraz.gz
zawsze 3,2 GB i przerywa

partycja źródłowa 50GB miejsca na docelowej na obraz ponad 100GB (ReiserFS) więc nie jest to wina braku miejsca.

Dodam że problem występuje zarówno na 32 jak i 64 bitowym systemie.

Partycję źródłową formatowałem z różnym systemem plików (ext3,reiserfs,ntfs) i zawsze jest to samo.

Ma ktoś jakiś pomysł ?

Dmesg lub inne narzędzia (smart*) nie sugerują uszkodzenia samego dysku?
