Without going into the 6 month saga of trying to get 2 internal sata drives to work, I’m ready to take a hammer to them. System Specs HP 8200 dual 3.20, 2G Ram, xpro 4.6/mojo, PCI 64 FW card, 2 -seagate 7200.8 250G sata, promise fastrak tx4 150 sata controller. Work 99% in DVCAM. Keep getting vid overruns when trying to capture. I deleted my array and rebuilt it using the auto config in the fastrak’s bios, I repartitioned and re intialized the drives as basic volumes, NTFS. Same result, won’t do it. I’ve heard about the promise cards not working but I’m not sure how true that is since some are using it successfully. If promise doesn’t work what card will do the job? I know this subject’s been beaten to death but maybe somebody might have some new experiences.

Your SATA drives don’t have the throughput to handle your captures. That’s why you get an overrun on capture. The drives can’t take the data away and store it fast enough. You need a minimum of 4 striped U320 or Fibre Channel drives.
Avid pushes the computer to the limit in a number of ways, and you can’t just put anything you want into the computer and expect it to work correctly. Many people seeking help for malfunctioning Avids on the Cow have tried to use the wrong display cards, make do with too little system RAM, or use hard drive storage not suited to the application.

Point well taken but I just didn’t stick anything into my machine. My system is per avid specs straight from the website. As I said, HP 8200 dual 3.20, 2 G ram, NVidia FX1300 gx card, ADS PYRO PCI 64 second FW card for ext FW drives. MY sata drives are Seagate 250G 7200.8, 7200RPM sata drives striped raid 0. The controller card is a PROMISE Fasttrak 150 TX4. It is located in slot 5 on it’s own bus segment. The more I hear about it, the promise card may be the culprit. I’m not sure the drives are the issue. If I understand you correctly, seagate 7200 RPM drives with are not fast enough DV25411? Also, there are quite a few sucessfully using internal sata arrays on both forums.

As you point out, several are using SATA arrays sucessfully, but many are not. 7200 RPM drives are marginal for DV25 media storage. Avid web site specs them for program storage only, not for media files. Most use 10K or 15K RPM drives. It comes down to this question: Can your combination of driver card and drives push enough data through fast enough? The fact that you are getting overruns on capture indicates that they are not fast enough.

Sorry, but this is why you don’t ask an editor a technical question.
Yes, 7200 RPM drives are fast enough to push DV25, DV50 and even 1:1, maybe not across the entire spindle but a good portion of it.
It comes down to the card. If you try and use a budget promise card with its crappy onboard RAID options, you’ll come out on the short end.
If you want to use your internal SATA drives and the card you currently own, don’t RAID the drives. Config them as individual drives. If that doesn’t work try the Promise SATAII150 TX4. I’m having great luck with this card. DV25, DV50 and uncompressed on Windows stripe sets and individual drives.

Thanks for the responses. I totally agree with you Bill. It definately is a too much data, can’t keep up issue. In the world of 20/20 hindsight, the grief I’ve spent with this far exceeds the little extra $$$ I would have spent on the 10K drives. Now, I’d pay dearly just to have someone fix it once and for all.

The following will resolve your problem. You have two Seagate 7200RPM Sata drives – correct? Get TWO Firmtek Seritek SATA Host controllers (they make a 2 port and a 4 port, but I am not aware that the 4 port has support for Win XP), and stick the 2 TWO Port Seritek SATA host cards in slots 4 and 5 of the HP xw8200. Use 4 Seagate SATA drives, and use Microsoft Windows Disk Manager to stripe all 4 drives RAID 0.
You will ABSOLUTELY be able to get 1:1 uncompressed SDI with this configuration, and this is a CHEAP SOLUTION. I assure you this works. Don’t use the Promise card – the Firmtek comes with the driver software CD that you will need (it will auto install).
I love these “this is the way it has to be” opinions from people that don’t know.

Thanks, sounds like a great solution. I do have the seagates 250G 7200.8 drives. I’ll look into getting the firmtek cards. It would so great to get these drives running the way they should.

I had wanted to point out that my drives are internaL SATA drives. Also I see the cards, went to their website. These boards are for a mac but work on the hp 8200? That would be cool and they’re so reasonably priced too.

I’m sure Bob’s solution will work, but there is no need to go with 2 SATA cards. If you are going to stripe them using Window’s Disk Management, then a higher quality card, without RAID, will work just fine.
I’ve used cards from 3Ware with RAID on the high-end to the Promise card I mentioned in my previous post on the low-end, all with great success.
