If the current system sees an ide drive you can easily slave the drive on the same cable and allow Windows to detect and install it as a new device provided the partition(s) are still intact. From there you copy + paste files and folder as you go along.
For troublesome partitions that can't be read from an older system the options for use of a data recovery program or seletively choosing a live for cd Linux distro like ubuntu, Knoppix, or a few of the numerous others allows for viewing and copying files from a partition otherwise unreadable. The image here shows copying files from an external usb drive onto an internal sata is done while booted with a live version of ubuntu.
