How to control speed when using Exact Copy

I went to the website mentioned for the feurio.com. How do I know which cables to buy for my computer. I'm not that much of an expert on the cables inside these things. I have a Dell with hard drive, CD/DVD, and CDR. Finding out which cables to order would sure be helpful.

You really need to open up your computer and see how the cables are connected to the hard drive and CD drive (in most cases they will be flat cables that look like a ribbon). Usually there is one cable that connects the hard drive(s) to the motherboard and another cable connecting the CD/DVD drive(s) to the motherboard. You will most likely need 2 cables. I would have recommended 2 of the RD3XP-A32 (20 in.) but those seem to be discontinued. You can get the RD3XP-A52 but those are overly long cables (28 in.) and may be hard to fit those inside a computer case. If you only have 1 hard drive/cd drive on the end of each cable, you can get the cables with only single connectors (either the RD3XP-A3 (12 in.) or RD3XP-A5 (20 in.) depending on how long a cable you need. If you have 2 devices connected to the same cable then you have to get the cables with 2 connectors as mentioned above. It's a shame some of these cables are being discontinued, as they are the best internal computer cables out there, that I know of.

Laurentgilles - go to Drive options and then the offset/speed tab. Speed options will vary some according to the drive that you have but EAC allows 6 options for my drive. From 4.0x to the maximum potential.
