The answer to your first question, is that there is probably no difference at all. EIDE cables went the way of the dodo around the time the ATA specification came along. Unless your system is circa 1995 or so, you probably have the 80 wire cables they talk about.
And as for drivers... No. Those are supplied by the burning program by and large. I would also strongly advise pretending InCD, and other "CD as a floppy" programs don't exist. They are a never ending source of compatibility and lost data issues. Use them at your data's own peril.
My current DVD burner finally died and became a DVD ROM basically. So I picked up an LG DVD-RAM burner model GSA-H22L.
This thing can burn DVD's at the speed of 18x (it can also burn the DVD-RAM and has LiteScribe burning too), and suggests to use the provided 80 pin E-IDE cable provided because the standard 40 pin E-IDE would not guarantee the best performance. Now, I do know something about these cables and how to count LOL. The only difference between the new cable and the one already in my computer is flexibility - meaning the new cable is hard to bend and the old one isn't. Plus, I did count the pins on all the connectors and there is the same number.
Question #1 - Does anyone know what is the difference between the two cables??
Now to install the driver for this drive, I have to install the Nero Burning software according to the LG website. (incidentally, the disc provided has this firmware update program & I checked the website and no firmware update is available) I checked the LG website and there is one place for drivers and firmware for DVD-RAM. The site also says that drivers are third party provided and they can't post them on their site. I have used Nero in the past and really don't like it and I am comfortable with the burning software provided with my computer.
Question #2 - Do I really need to worry about a driver for this burner? I just burned a data DVD at 16x which is the fastest speed on that blank DVD and it burned it ok. Their website states that drag in drop driver support is provided with Nero InCD. This tells me that I only need a driver if I want to do drag n drop.
Thanks for your replies.
