Dropouts Can't Post

We just edited a wedding shot on 2 xl1s' and had noticed a few digital dropouts off 1 of the cameras, the same dropouts remained during the editing process (no worse no better) but when we finished and went to vhs...... Dropouts everywhere!
We always use firewire to load into Avio and always direct (level 7)
We were about to "re do " the entire wedding until I used the finish to Record to DV via firewire back to my camera to the vhs deck,using the camera as a pass thru. All worked fine.
ps When the dropouts occured you could here the chatter of the hard drive (if the volume was down)

Is there a 80 gig drive to use that is any better than an other? Currently using Maxtor 7200rpm

Re: Dropouts Can't Post

Mr. Simms! greetings from all of us at the msus boards:-)
MSUS said 3 hd's would work in the avio best...
maxtors ARE NOT ON THAT LIST
1.western digital
2.ibm
3.seagate
4.not maxtors! lol.. i've heard of problems using maxtor's for video before... that was in pc world though
basically anything with a 8mb buffer would/should work fine for digivideo... And 7200rpms... 5400 can and does work for digital video editing..but it is prone to stuttering/skipping more frequently than the suggested 7200rpm drives...
I have ALL western digi's in my avio and pc.(7200rpm with 8 meg buffers)
an 80 in the avio
then 2-120's and a 40 in my pc.
they all work great.

btw doing 2 cams isn't that bad with the avio right or wrong?
btw again.. i did one qith the greatest of ease with premiere this week... using a real time pic in pic from canopus 2 laid it over my second AND third cameras and cliped out whatever i didnt want from the 2 insert cameras and used the main cam as a audio and video main track...
BTW I added the audio from the second and third cams when they were on mixing it into the final edit without rendering each one to hear it's quality and sync:-)

I've used almost all Maxtors in Avios, Krons and PCs. Extremely little problem with them. The problem is typically NOT with the drives, but with the controllers or something else in some Avio/Krons.
My aging PC (1.4MHz) has four 5400 RPM Maxtor drives (60GB, 80GB, 100GB & 120GB). Using Avid Xpress DV 3.5, it's no problem to play back 3 layers of DV video with effects on them in real time. I've done sustained read/write test and they always run at least 20MB/sec datarate. DV is about 3.6MB/sec. Granted, they probably would be a lot faster if I had newer hardware, a better hard drive controller, tweaked them a lot, and did some defragmenting once in a while -- but I'm too cheap and lazy for all that -- after all, it's working just fine now.
OTOH, on the Kron and the Avios, after adding the expensive firewire cards, apparently have some severe hardware limitations. Instead of purring along at more than 20MB/second, they have trouble keeping up with one stream of 3.6MB/second data in the DV-Direct mode. They were really designed for the MPEG2 mode, maxing out at about 2.1MB/second. It's a real shame that you have to over-buy hard drives (faster than 5400RPM, bigger buffers, more expensive names) to get over this hump.
But Chris, back to your problem. If your unit is bogging down at quality 7 with a 7200RPM drive, I would think either the hard drive or the unit is certifiably defective. I've never had even a stutter in the MPEG modes with Maxtor 5400RPM drives.
