Honestly I am at my wits end in troubleshooting this issue..... ;0(

I will try & explain what I've done so far but it has been exhaustive & may have missed including it here so please bare with me.

The bottom line problem is that data is corrupting on this machine when I do "network" transfers, or sometimes partition/partition/drive transfers.....2 examples:

1) I create images to a seperate drive in the machine. If I restore that image from where it was originally written it's perfect....If I copy that images to another partition(whether it's the same drive or not) and restore it the image errors with "corrupt or invalid image."

2) Large file transfers across the network no matter what drive/partition I copy to it corrupts. But very small file transfers are fine????? I have 8 computers networked in my home and this one is the only problem with corruption.

Here's what I've done:

1) Ran memory tests(memtest full 18hrs), removed memory, used different memory.
2) Changed the RJ45 cable leading to the NIC and used various ports from my router & 8 port workstation.
3) Disabled the onboard NIC card slapped in a PCI NIC.....Worked great for awhile than crapped again(I've tried various NICS and the ones I've tried worked perfectly in all my other machines & no corruption. Even the one that crapped worked great on another machine....
4) Removed **ALL** hardware (CDRoms, etc) & only left a stick of memory & one harddrive, did a **CLEAN** install of both Win2K & XP with no updates on the machine & the data still corrupts.
5) Ran full drive read/write scans on the harddrives present, no issues. Put these drives in other machines and data transfers were perfect........

I think I may have covered a good portion of what I done......I am by no means a rookie at this stuff but this has got me twisted as data tranfer is vital to me for the use of this machine.........I do use tools to verify the data which is QuickPAR and/or a SFV verification file.

My warranty is up so calling tech support is useless and personally I think I'll be fighting with them more with their basic approaches.....I can't deal with that right now ya know, blamin the OS, I don't have their original OS crap on it.....Go to start/programs, dbl click this.....Arrrrrrrrrrrgh!!!!!!

I would REALLY REALLY appreciate anyones help on this.......And yes I know proprietary blows but this machine was an exceptional deal......I always build my own.........




Could be the CPU is getting a little too hot on the longer data transfers. Download Prime 95 and run the "torture test" mode. It should fail out pretty quick if that's the case. Maybe you could get away with cleaning the HSF assembly and putting a fresh coat of grease on it. Just for the heck of it I'd try a different Video card too! (might be some memory leak going on there)
