Bizzare File System Problems

[EvilPokemon]

I have to say, I've never even heard of anything like what I'm experiencing.
My system has a serious problem adding new files.

It's not a physical hard drive issue, scandisk, and Disk-Checker, both turned up zero issues.

All existing files are just fine. You can run defragmenter, and everything is still fine. From system files, to large media files. Everything already on the drive is still good.
Adding new files that expand from existing files(IE installation programs) also results in no issue.

However, this is where it gets fun.

Any file over 3mbs, I try to download, comes up corrupted. Regardless of browser or download manager.
And about 1/2 of files I transfer off of cd are corrupt.
BUT %100 of files I download that are under 3mbs download without issue and work just fine.
HOWEVER, any file copied from a floppy disk is corrupt, regardless of size.

This is present both under XP as well as 2k. I even tried a clean OS install, and the exact problem continues to present.

This is the absolute wonkiest thing I've ever seen, and have absolutely no explanation to it.
I have a hunch reformatting the drive will solve the problem, but I don't want to take the easy way out
I wanna root this problem out.

Who wants to take a crack?
Keep in mind, any diagnostic tool you ask me to install will have to be < 3mbs

hi man, i have the same issue with my mobo controller ICH10R - i have posted in some forums here, so i think this problem is some bug in firmware/drivers of the controller. can you give more info about your PC config?

You might want to try different SATA ports, or barring that, different SATA cords. Eliminate all possibilities, including the cables and ports that connect your hardware together.

If it turns out to be a controller issue, you might want to consider getting an add-on SATA card and/or a motherboard replacement if those turn out be the culprits. Definitely sounds like something hardware to me.
