Disclaimer: I haven't messed with image extraction from the Hitachi or Samsung 360 drives (I use a SH-D162C).
I believe you can use the Xecuter kit and your Hitachi with the latest Xtreme to have the drive permanently in ModeB for image/SS extraction.
If you plan on having the Samsung permanently in your PC, I suggest you not use Xtreme3.0. (You'd have to insert the enable0800 DVD every time to put it in 0800 mode. Instead, flash the drive with xtrm0800.bin from the Xtreme1.0 package.)
If it weren't for the issue that the Samsung sh-d162c (PC drive) can't yet read the SS.BIN, I'd say pick up one of those bad boys and flash it with the Kreon firmware. (Or trade one of your 360 drives for my SH-D162C
