New harddrive, but i now have recording problems.... (1 Viewer)

Hi there.....

--EDIT--
motherboard: MSI KT880 Delta-FSR (VIA KT880 chipsset)
drivers: MSI VIA4in1_v5.00
--EDIT END--

I have had this Seagate for a long time without any problems.
I could record at high quality, and watch a recording at the same time, and no problems at all.
Model Number: Baracuda ST380021A
Capacity: 80 GB
Speed: 7200 rpm
Seek time: 9.5 ms avg
Interface: Ultra ATA/100
Cache: 2Mb

Now i have a new SATA drive on the same HTPC, but it is a Maxtor:
Model Number: MaXLine Plus III 7V250F0
Capacity: 250 GB
Speed: 7200 rpm
Seek time:9 ms
Interface: SATA 300 Mbps (@ 150Mbps)
Cache: 16Mb

And now i got problems when recording (not even watching anything at the same time), the recording is somehow in "stopmotion" or something like that, (i can´t explain it well in english), but it looks like some frames is missing somehow, so the picture jumps a little forward..... (I hope you understand what i am talking about)
I think that the cause for this is that the harddrive is too slow, but how can it be too slow when it is faster and with more cache ??

Is there something i can do about this ??
I´m new to SATA, so i´m a little lost here.....

Can it somehow be a driver issue, or is SATA drives just not fast enough for HTPC even thoug they have a faster bus (by 50% in this case) ??

I can say that i have installed the newest drivers for my mainboard, and i have also updated the bios to the newest, but without any improvement....

Pleace help me.....

What MB do you have? Is it with a NVIDIA Chipset? If so, what driver are u using for the disk?

Yeah the Si3112 SATA chip has been associated with this kind of behavior, most notably with Fusion 5 cards, but also with others.

Hi there.....

I didn´t remember to give that info..... sorry.....

The motherboard i have is a MSI KT880 Delta-FSR, with the VIA KT880 chipsset on it....

The drivers i´m using is the newest from MSI´s site....
VIA4in1_v5.00

Yeah the Si3112 SATA chip has been associated with this kind of behavior, most notably with Fusion 5 cards, but also with others.

So you say that there is nothing i can do about this ??
Is it really true, that i can´t "optimize the problem away" in some way ??

I don´t understand this, as the drive should be mutch faster in every way over the old 80gb drive i have......

The southbridge is not with the SI3112 chip, it is a VIA:
• VIA® VT8237 Chipset
- Ultra DMA 66/100/133 master mode PCI EIDE controller
- Supports Serial ATA

Should i buy this controller then :?: :
Promise
ATA300 TX2+, 2 SATA (SATA300) + 1 ATA133
Model: SATA300TX2PLUS

- and will that solve my problems ??

An other thing is, that i have tried HD tech, and with that, my new Maxtor drive is far better than my two old drives..... (but they works both fine when recording.. :?: :!: :?: ...)
