Dd Fails To Copy Image Over?

[tkc]

i've tried a few times to use windows dd to dd tiger-flat-x86.img to a partition but have failed to get it to work. after dd, it shows only 6000+ records in, out. and upon rebooting, i tried to boot up into osx86 but get a chain booting error. i'm using the wiki's install on a partition simple and accurate method.

 

here's what i've got:

a single hdd with 3 partitions - 1st partition is a hidden partition, prolly for rescue/restore purposes, presumably created by my the makers of my laptop. 2nd partition is c: with winxp. 3rd partition is a 6.5gb partition created using diskpart as stated by the wiki - create partition primary size=6660 id=af.

 

using dd for windows v0.3, i used the command dd if=tiger-x86-flat.img of=\\?\Device\Harddisk0\Partition3 bs=1M skip=63. this takes around 10min to complete but it's also the part that leaves me wondering what i've done wrong. and as stated earlier, it shows only 6000+ records being written.

 

the img file was extracted usig winrar 3.5, and is 6gb+ in size. using acronis partitionexpert, i've verified that the partition is in 0xaf format and is a primary partition. however is this partition perhaps a bit too small to contain the image output from dd? should i set it to 7gb? or is the dd command at fault here? maybe i should use bs=512, even though it'll prolly just take a lot longer and not make any difference?

 

any help appreciated. thanks.

 

edit: installing osx86 on a laptop -

pentium m 1.6 with sse2

512mb ram

60gb hdd

no floppy

dvdrw drive

i think i figured out the problem. it was caused by me using bs=1M. i think it is necessary to use 512 as block size, or whatever block size is specified by dd when u use --list.

 

output when bs=1M:
