cloning

I have a problem with drive cloning. Im using dd on damaged disk with bad sectors trying to make an image from it. Im booting computer with Live Linux CD .

Damaged disk: sda 146GB (NTFS) External drive: sdb 300GB (NTFS)

After running the command below im running out of space on disk sdb.

dd if=/dev/sda of=/dev/sdb/hdd.img bs=4096 conv=noerror,sync

The question is why im running out of space on disk sdb ?
