That CHKDSK process may take quite a bit of time, and 6-8 hours is not at all uncommon, especially on the larger disks. When I was less experienced, it was an easy way to get Windows to boot again. Now that I know better, I'd never let it complete due to the mess it creates when it's confusing physical with logical failure and attempting to "fix" it. Imaging, and fixing the disk image would actually be faster.
You are still within the logical recovery realm, but your data is available for a limited time. Don't delay in deciding what to do, as it may become a physical failure at an exponentially greater cost.
You can still do it yourself. dd if=/dev/sdb of=image.dsk bs=50000 could do the trick, for example, if the disk was accessible in linux as /dev/sdb
