I'm cloning a windows disk using gentoo; On the old 66GB disk; # dd if=/dev/sdb of=/root/winmbr.bin bs=512 count=1 # dd if=/dev/sdb1 bs=10M | gzip -v > winpartition.gz
Then after swapping in the new 500GB disk; dd if=/root/winmbr.bin of=/dev/sdb bs=512 count=1 # gunzip -c winpartition.gz | dd of=/dev/sdb1 bs=10M dd: writing `/dev/sdb1': No space left on device 0+306 records in 0+305 records out 10137600 bytes (10 MB) copied, 0.109885 s, 92.3 MB/s # fdisk -l /dev/sdb Disk /dev/sdb: 500.1 GB, 500107862016 bytes 255 heads, 63 sectors/track, 60801 cylinders, total 976773168 sectors 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: 0xe3f7e3f7 Device Boot Start End Blocks Id System /dev/sdb1 * 206848 117207039 58500096 7 HPFS/NTFS/exFAT Why is dd saying no space left after copying 10MB when sdb1 is 65GB?
