Can you test with another drive to rule that drive out as the cause of the issue? If not, have you at least ran the manufacturer's testing tools to be sure the drive is fully functional and passing all tests? Since this is an old drive I'd test it for sure, in case the drive itself is the problem
Hutil
http://majorgeeks.com/Samsung_Drive_Diagnostic_Utility_Hutil_d5769.htmlAnd run this one as well (Samsgun ES-Tool), backup the drive before using either of these though, as there is a write test that writes to the last 8MB of the drive (Not usually an issue, but backup is always advised). Since Seagate now owns Samsung, all the Samsung links I could find are down, so you'll have to download this bootable CD with many other tools in order to use the ES-Tool for testing
http://www.ultimatebootcd.com/I also see this drive can be aligned to 4k sectors like SSD's, s not doing that might cause issues. Did you do this or do you know if it was already done? If you are not sure, please download the following benchmark and open it and select the main partition. Do not run the benchmark, just select the drive. Download is at the very bottom
http://alex-is.de/PHP/fusion/downloads.php?download_id=9Why do you keep mentioning IDE? You mentioned an 80 pin IDE ribbon cable in your first post, and again mentioned IDE in the #6 post. Just asking to be sure, in case maybe you are using some other older IDE HDD with an adapter or something.
Did you use Express Install from the motherboard CD when you installed windows? If so that may be the issue. If you did that, please remove the Marvell drivers with device manager and add/remove programs.
And then update the Intel drivers
