Camera to computer via Firewire and out by Firewire to external drives problem

I'm getting occasional dropped frames for the first time ever. Looking into it, it seems to happen when digitising out to an externally connected 300gig Firewire drive when the camera is also linked by Firewire to the computer. My Firewire card has 3 Firewire 400 ports.

I had intended to get an external 8 hard disk drive from someone like Span using the Firewire 400 connections but it looks as though the Firewire 400 3 port card connection might not be able to cope with camera data coming in and being saved externally.

Should I be looking at the 800 Firewire standard card set or perhaps 2 Firewire cards. I'm about to go to HDV editing so cannot risk an unnecessary dropped frame or can you take a connection out from an IDE lead or perhaps something else altogether.

In the meantime I'm digitising to an internal drive and then transferring the data later to an external drive but it's a bit mickey. Any thoughts please - gratitude.

If you have room inside your case add an ata133 pci card and harddrives to that.
You can also get pci cards that allow external ide/sata connections.
I too have problems with some machines with firewire drives when it comes to capturing , and believe it is down to motherboard/firewire chipset related.

Hi
All the PCI slot FW800 cards I have seen have some small-print in the tech-specs:
"requires 64-bit PCI slot for FW800 speeds, will revert to FW400 performance in a 32-bit slot..."
Do you have a motherboard with 64-bit PCI slots?

Check to see if file indexing is turned on , it is the default and I have found that this can cause problems like you are experiencing

Gary - thanks, that seems a straightforward way to connect a box full of drives.

Paul - I think I'll try to stay with Firewire 400 for the moment but thanks

John - thanks for the advice, where do I find 'file indexing'

I'm surprised others haven't had this problem though!

HI To check for file indexing

Right Click My Computer, Right click on the Drive, and then select properties, on the bottom of the box you will see two options, on is for Compression that you Definitely DON"T want on and the other is for file indexing that you also don't want to have checked

I must first double click on the Left !
Then the rest of John's statement is applicable .
