Copying Vista DVD to Flah


Recommended Posts

Ok so im using one of my *nix machines to copy a Vista install CD to flash so I can boot into it from my eeepc. I'm using DD to do this and the command i've used it:

dd if=/dev/disk1 of=/dev/disk2 ibs=4b obs=1b conv=notrunc,noerror

Ok I've left this running for around 2 and a half hours now, and before i left it for about 1 hour stopped it and the partitions and everything where on the flash drive but obviously it wasn't finished and didn't work....

Question is how long should this process take.

Also top is stating that DD is using 0.3% of CPU power.

any help will be appreciated. Thanks.

EDIT: DAMNIT I spelt flash wrong in the title :p

why's that? it seems to be copying data accross when i canceled it.

53481472 bytes transferred in 2287.187993 secs (23383 bytes/sec)

Are you sure it won't?

So i should use DD for windows then?

Did you use the hp utility to make the flash drive "appear" as another type of device ?

I had always heard that booting/installing a windows OS from a flash drive was a bitch.

But, I dont think anyone was doing it from a linux enviro

Why on God's green earth would you read a CD 4 bytes at a time, and write one byte at a time? :wacko:

Maybe try reading and writing 1k at a time?

lol, I came here to say that. And wont this not work because you're copying an ISO9660 filesystem to a usb stick (essentially a hard drive)? Pretty sure this wont be bootable...

yeah your right its not bootable, i tired without reading 4 bytes at a time and writing 1 byte at a time but it was still heaps slow.

It actually doesn't make any difference in copy time really when I tired it on ubuntu it was about the same speed with out without those settings.
