I just bought this scanner today and it can with a bundled software package which I do want installed however I want to install it on a different HDD than the default one but even under custom install I can't finsd a option to change which HDD the software gets installed to. I just installed a HDD just for use with this printer as I will be scanning a gazillion OLD photos and I wanted them off by themselves. Any ideas would be appreciated.
