    I've been wanting to try my system with the two HDD on seperate channels so got some nice new long (60cm) round cables.

    However, to get them to fit a HDD low in the case and a CD-Rom up at the top, plus another low HDD and high CD-RW, I had to plug them in the wrong way round, result, won't even boot.

    2 HDD were configured masters, CD drives as slaves.

    So, does anybody do cables with blue mobo end connector, a short gap, connector, a long gap, connector, preferably round?

    i know its late, but do you mean that you had the 2 HDDs as master on one channel?

    if so thats not going to work. the max length ive seen for cables is 90cm, and people say thats too much but they do work still with no data loss or whatever.

    Just a quickie.

    You really should not put cdroms and hard drives together on the same channel as you usually get some performance loss.

    Usually rule of thumb is to have hard drives on on channel and cdroms on other.

    Cant help on leads im afraid, but if you live in the uk,

    a company called Suna Supplies make custom cables for just about anything pc realted..

    Not so. With the fastest drives (ie 2 HDD) on different channels one can be reading while the other is writing. With a CD-rom feeding a CD-RW on a different channel, disc copying is improved (less chance of a coaster).

    In the olden days IDE bus went at the speed of the slowest device, but not any more :D

    for some reason with ata 100 cables you cant put them the wrong way round so to speak, as i tried that with my extra long 90cm one (which has about 30cm between the two upper ide connectors which might be long enough for you!!!) but it does seem to work with the old style ata66 cable....

    might be cause on of the wires is chopped out just after the mobo connector....

    Current:
    IDE1 - HDD1 master, HDD2 slave
    IDE2 - CD-RW master, CD-Rom slave

    Desired:
    IDE1 - HDD1 master, CD-RW slave
    IDE2 - HDD2 master, CD-Rom slave.

    Total cable length isn't a problem, it's the gap between the two drive connectors that's too short on my so-called "long" cables.

    It's an Antec 1030b case with 2 HDD in the bottom (fan-cooled) cage.

    How do u mean? Aint there a notch reventing pluging the cable into the device the wrong way around.

    Or do you mean plugging the 'blue' end into the device and the 'grey' end into the mobo, in which case should make a no difference.

    just need to say this if u have a ata100 controller

    hdd1 ata 100
    hdd2 ata 66 ( on the same controller ) that ata 100 drive will slow down to the ata 66 drive which is why when u plug cdroms with the hdd in the same controller u get a system speed loss

    edit: this applys to cd,cdr,cdrw drives as well as scsi

    Re: Re: Long gap (between drives) ATA66+ cables

    Tell that to my computer. "Boot drive failure" came up.

    Flix-the-Cat hit it, I think, some ATA66 cables (or an ATA66 mobo)might work, my ATA100 ones don't.

    Gap between drives is 30cm (12").

    UATA66 cable = UATA100 cable = UATA 133 cable. They are all the same.

    cpemma- try 90cm rounded cables. These may give you the reach you're looking for.

    Out of interest... wot mobo u running? Is it as old as my A7V :blush: ?

    Coz on mine, the ata100 is controls separately from the other ata66 bus, and I had to install the O/S onto the hdd conneted to the ata66 channel and then install the ata100 drivers, b4 i could run the O/S hdd off the ata100 bus. Its a right pain when I'm formating and reinstalling :grr:

    Time for a new mobo me thinks :D

    And more at http://biz.howstuffworks.com/ide.htm?printable=1

    I've found a couple of references saying ATA/66+ cable should be no more than 6" between drives so I'm forgetting the idea.

    Should have bought the RAID board and had 4 channels. :cries:

    GunDam - nothing wrong with the cables, they're fitted now, MSI Turbo LE board.

    Isaac - Tekheads 90cm look to have the same 15cm inter-drive drive gap as mine
