    Post Long Hard Drive Cables

    I know this has probably been talked about before, but would it be possible to mount the hard drive in the dash or in the glove box with a cable running to the trunk, or is that too far?

    I have heard about a select *few* people who have had success with long ide cables. In reality, they're not supposed to be much longer than 24", 36" will work, and so will 48 probably...but after that you're going to start getting data loss from interference and crosstalk. I have made a long ide cable work successfully at 15 ft. by using 24-pair twisted pair cable covered with aluminum wire shielding. If you want to know more...go to my site and read the in-dash dvd how-to. It may be of some help to you...

    pinkysqueaks: I read how you extended your IDE for your CD-ROM, but am questioning some issues. You said MP3s play fine... That's on average 192kbps of data being sent. I wonder if you would have any problems with data from the DVD drive with a 15' IDE? If, of coarse the reason for data loss is only interference and crosstalk the length is almost irrelivent. I just always thought that signal loss was related to the low voltage traveling far distances. I am though, totally guessing and could be making an *** of myself. Either way, let me know how the DVD player works out. I have mine in-dash with a 36" IDE and works fine. Good luck.

    pinkysqueaks....this is off the topic of the thread but i was reading about your power issues and I wanted to throw my two cents in. I really don't think you need to get your alternator rewound. I also have a 65A alternator in my car. My PC isnt in yet but I do have a stereo system. Ive got a DEI Directed 600D amp pushing about 600 watts RMS (1000 peak) to my two subs. Now thats sucking a lot of amps well over 60 (toasted my main power fuse when i put the amp in) Im guessing I'm drawing about 70ish amps at full tilt. I havent had any problems other than my headlights dimming out on heavy bass hits...And I also have experience with Jensen amps. They have good sound and are a great bang for buck buy. But they are overrated as far as power goes. And you PC wont be using the full wattage from the inverter.

    So anways in conclusion try it all out before you rewind your alternator. I really dont believe you'll have a problem

    PS If you ever want to seriously bump with those subs go get yourself a Directed 250D amp..its mono and will only push subs but man will it hit.... I had one before I upgraded to the 600D

    Cat-5 is the cable commonly used to wire up EtherNet. It contains 4 twisted pairs of 8 wires. It comes in both shielded and unshielded.

    well, I'm the furthest thing from an expert on this topic. what I do believe is that when you're dealing with 15 ft for a length with IDE, the low voltage is not much of an issue. I think data loss occurrs more because of EMI/crosstalk. But weak signals must be an issue at some point...

    of course the only evidence that i have to back this up is the fact that i've made and tested a 15 ft cable myself and with proper shielding, have gotten flawless data transfer. it wouldn't seem that the transfer rate makes a large difference....but then again..i dont know. anybody know more? i am curious.

    I saw something a while back on this list that used 74LS244 Octal Drivers (amplifiers) to boost the signal in an IDE cable.
    Sadly, all the posts were lost a few months ago...

    Anyone know anything about amplifying the signals?
