Neo 4 Platinum - always problems! :((

Question

Sorry for my bad english.
After working a while on this mobo, I am unable to working in a stable way and the problems are very big to me and now I have only problems.
Well, in order let me explain what happend:
I have a Maxtor 80 GB SATAI connected on SATA port 1 (nForce) (2 partitions) and this is the boot disk where Windows is located.
I have a Maxtor 300 GB SATAI connected on SATA port 2 (nForce) (2 partitions)
I have 2 Western Digital Caviar 80 GB E-IDE connected on nForce PATA1 Master & Slave and configured as RAID 0 - Mirroring with nVRAID (2 partitions)
I have 2 Optical Drive (a DVD-ROM and CD-RW) connected on nForce PATA 2 Master & Slave
The problems are that If I move larges files or a big amount of files (about 20 GB in one time) from the RAID to one of the SATA drives (or vice-versa) the system crash... well hung up. The video signal go away and return (black screen, windows desktop then black screen again and so on). After 2-3 times the desktop re-appear but the system is hang up so a hot reset is necessary. After that... I have encountered these problem (i've tried many times):
1st time: Hot reset, at the restart NVRaid detect defective the Mirroring array, So I've pressed F10, rebuilded the Array. Then in Windows the hard disk disappear. In disk management the Mirror disk is seen with a exclamation point and I cannot import the "external disk" (so, I've disabled the RAID, returned to Windows but only one of the 2 WD disks can be seen)
2nd time: Hot reset, at the restart Windows cannot find a file from the 80 GB SATA so I've formatted the partition and re-installed Windows, I've repeated the file transfer but after a while, the system hang up again.
3rd time: At the restart, Windows try to load but during loading the system reset automatically in an infinite loop (try to load windows, reset, try to load windows and so on), so I've tried to reinstall Windows (pressing F6 at the installation to load the NVRAID and nForce Storage Controller) but when It's time to check the disks I receive a Blue Screen of Death with an error on NTFS.SYS file and PAGE_FAULT_IN_NONPAGED_AREA. After some investigation (and curse) I've found that the 80 GB SATA seems to have "lost" the filesystem or similar... at the moment of this post i'm unable to access to the disk (if someone knows a DOS utility that can recover SATA disk... let me say!) because If i connect the disk in Windows (or while Windows is loading) I receive a BSOD. Now I'm running the OS on a PATA Hard drive (an OLD Quantum 13 GB) because I don't want to lost any kind of data from my 300 GB SATA and 80 GB WD PATA hard drives... but i'm unable to work in any type.
The bios is the 1.5 (but the problem is also with 1.2!)
The configuration:
Athlon 64 3200+ Winchester
TwinMOS 1 GB RAM in Dual Channel Config (Samsung TCCD)
MSI Neo4Platinum
80 GB SATA Maxtor
300 GB SATA Maxtor
2x 80 GB Western Digital Caviar
ASUS GeForce 6600GT
Pinnacle PCTV Pro
SoundBlaster Audigy 2 ZS
<Latest nForce 4 drivers>
Please let me know anything because it's very important, and now i've also an 80 GB SATA hard disk that I cannot use in any type (i can't format it, I can't connect to the mobo etc)

Answer 1

In this period I've made a lot of tests trying to find a possible cause.
After a deep analysis, partitions and MBR losts, Hard disk not detected by BIOS, data lost and so on (Thank you VERY MUCH Mr. nVidia for let me test YOUR hardware with MY money!!) I've found a possible cause.
I want to report here the status wishing that could be helpful for others and in particular for nVidia which need to do a BETTER drivers and has sure a poor quality check.
Well, I've forced 2.60 Volts in the BIOS for the RAM, disabled NCQ in drives that support it, Windows driver for PATA controller and I've re-tested all... but AGAIN... BSOD and MBR/partitions fuc*ed. So I've re-do other test and in particular I've burnt 4.37 GB (a DVD-R) from the Maxtor 300 GB SATA and, surprise... again BSOD... SO I've concluded that it's not a SATA to PATA problem... but a worst simple reading from the SATA HD.
This time in Device Manager I've disabled Write/Read Caching for ONLY the Maxtor 300GB SATA (I want to point out that I've also an 80 GB SATA that have Write/Read Caching enabled and works like a charm!) and I've re-do the transfer that previously made the BSOD. This time fortunatly all go OK. I've made also a lot of other transfer... and all OK.
So at the end... Seems to be not an hardware problem (the 300 GB Maxtor is healthy, tested and re-tested), PSU is OK, memory OK, CPU OK... but a sucks drivers that cause the problem. Probably the 16 MB of buffer could be the "problem" for the drivers but surely they're very FAR from good. The latest drivers (6.66) HAS the bug... ALL drivers (from the 1st that support NF4) today are affected by this big bug that fu*k the hard drives so is not a "stupid" bug. I dunno if it's the 16 MB buffer, if it's an incompatibility between NF4 and Maxtor 300 GB or if it's the size or anything else... but the Maxtor 300 GB works PERFECTLY on a Via chipset and doesn't works on a NF4 board without the "trick" (also with the trick the performances are obviously low but at least I can work)
I would like to thanks VERY VERY MUCH syar2003 for the working tricks and also this site (Anandtech) where in the "comments" there are other user with very similar problem (and the bad thing is that seems to be a common problem!)
