_ SSC is not an option you actually "choose" whether to use or not, but is more like the surroundings / environment imposes if there is a need to use it or not.
_PHY is needed if you want / need to connect that SATA6Gb/s HDD to your old system, where you have SATA3Gb/s controllers.
About DLGDiag 5.19 floppy creator, you have several options (not provided by WD
) if you don't have a floppy.
A) Using a compatible Windows System (XP for example),
A.1_ Use a virtual floppy software (VFD or IMDisk);
A.2_ Run the floppy creator;
A.3_ Save the floppy image from the virtual floppy as dlg519.img;
A.4_ Customize UBCD to add dlg519.img
_ both VFD and IMDisk can be installed or ran portable (not stealth).
_ read the relevant sections at UBCD website, like "customize", "tutorial", "FAQ's", "links".
_search this UBCD forum for additional info.
_when customizing, do not change dlg504f floppy image to replace it with the new dlg519 image, but make a new additional floppy image under the "custom" folder.
_ you could optionally gzip the dlg519.img to turn it into dlg519.img.gz, but you have to use the relevant settings for syslinux/isolinux and grub4dos menus.
_ after building the new customized ubcd iso image, test it under a VM before burning it.
_ for optimal compatibility reasons, try to use a burned CD (CD-RW or CD+RW if you want to reuse it) of the new customized ubcd iso image, instead of a DVD or UFD.
There are other options besides the "A)" mentioned, like for example:
B) using IZArc, ResHacker and Dynamite instead of VFD/IMDisk - that works also under other OS's other than the "compatible" ones;
C) turning the floppy image dlg519.img into a CD image dlg519.iso;
D) extracting the executables and testing them by replacing the previous versions with the new ones.
I think the "A)" option is simple enough to follow (and to write the relevant instructions
). BTW, I didn't write each and every step to follow, but a general procedure. Read the relevant sections at the UBCD website, the UBCD Wiki, and search this UBCD forum, for step-by-step instructions.
