Hm. Never seen that. I copy files from one hard disk to another all the time, the Finder preserves file creation and modification dates transferrin between on any Mac OS file system volume.
Copying to a FAT or FAT32 file system or a UNIX file system, sometimes the creation or modification date are lost. This is an issue in that the external file system does not always support the creation/modification date metadata. An example of this is copying a file from my boot drive to a flash drive ... checking the file with Get Info shows the Modification date on the file now on the flash drive is preserved but the creation date is "--" ... not supported, the field is NIL. If you're regularly shifting files back and forth between volumes built on different file systems, I can see where this might get to be a problems. All my hard drives are formatted for "Mac OS X Extended, Journaled" except for one, which is used as a transfer/temp drive in FAT32 format. If you want to be sure to preserve your modification and creation dates properly, create read/write disk image files on your alternative volumes, mount them in the Finder, and read/write your files to that virtual volume when mounted. Another possible cause is using UNIX-based command line utilities that do not preserve file specs properly. ... I'd have to know more about what your doing to really answer this any further.
