    Question HDD tranfer rate problems

    Hi there, this is my first post and I could not find an answer to this in the FAQ's so here goes. First of all my system (slightly modified DELL):

    P4 2.8HT with 1Gb DDR400
    2x80Gb Seagate Barracuda 7200.9 ATA100 HDD
    1xDVD ROM
    1xDVD DL writer
    Radeon 9800Pro 128Mb 8xAGP
    19" Samsung 930BF 4ms TFT
    XP Pro, Pinnacle Studio Plus v9

    That's the main stuff. Should be enough info I think. So the problem...

    I have no problems capturing video to my system disk at over 20,000kb/s via Firewire from my Sony HC35E Camcorder. However, my disk crashed and I have successfully replaced it with a new Seagate (listed above) and had a fresh install. Again, this captures fine, but I wanted to use a scratch disk for DV only to save my system disk getting scrambled over time.

    So I bought an identical seagate and installed it on the same channel (both disks on cable select with system disk at end of cable) The system all works fine for general use but when I set the scratch disk for capture, it tells me the transfer speed is too slow (around 2000kb/s as opposed to 4000kb/s required).

    I have tried a new disk as I thought it may be faulty, but have the same issue.

    Both disks are NTFS formatted and I have the two DVD drives on a seperate IDE channel set as cable select also.

    Any help or suggestions would be gratefully received. I can use the system fine for editing and rendering but I am frustrated that I have an expensive lump of HDD that I cannot use for capture!

    Thanks in advance, Dunnster.

    Caveat: I most definitely am not an expert.

    I believe that system and storage hds should best be on different channels for best performance, but 2000kbs seems very slow and makes me think something else may be wrong.

    Get some more advice but I suggest the drives should be on seperate channels.

    Talking Nice on!

    OK so I just tried the following:

    Channel 1:
    System HDD set as master, DVD drive as slave

    Channel 2:
    Scratch HDD set as master, DVD drive disconnected

    Capture rate to scratch drive - 50,000+

    SUCCESS!!

    So my next problem is, the standard leads are way too short so I guess I need replacements if I am going to reconnect in this configuration. Anyone know which ones to get...I will have a look on the usual sites.

    Thanks again for the suggestion.

    Go for the round ones. Much easier to fit.

    I've taken out and installed a few hard disks over the past number of years and the leads were always long enough. Have they really become shorter recently?

    On the size of your hard disks, 80GB is very small when it comes to video work. I'm transferring an SVHS wedding video onto the computer at present which is 3 hours long. So I decided to split it into 9 blocks of 20 minutes each. Twenty minutes of video takes up about 4.5 to 4.6GB of storage. So multiply that by 9 and you get around 40.5GB in total, and I'd leave a few more gigs for audio files, temporary files and still images. And that's just for one project.
