I recently rebuilt my computer with a new ASUS motherboard and a X2 3800+ using a new case, same RAM and HDDS/Optical I already had. So i built the computer and then I had some wierd booting problems. Windows froze a bunch of times while loading and so I had to reset it. Then it finally got to the login screen but my keyboard and mice werent working. SO i tied PS2 KB+M and i was able to login ok. While in windows it froze a few times before I was able to install most of the drivers I needed. I had to install a bunch of PCI and IDE bridges and stuff. They were usually slightly different in their names, but one time when i rebooted i had to install the same drivers again. Anyway. Once I got everything installed i took out the PS2 stuff and my PC stayed on the XP loading splash screen, so i figured out that i needed the PS2 stuff plugged in for it to finish loading. Anwyway, my real problem came wen i was using my computer. My 250GB Seagate STAT drive was read as not formatted (I think) at first. I unplugged it and plugged it back in bceause this has happened like twice before. Now when i click on it it says that the disc is corrupted and unreadable. I also have another 320GB Seagata STAT (VIA USB elousre) that is being read as not formatted. Im not sure at when point I had it on and plugged into my system. I ran HDD Regenerator on the 250GB, looking for bad sectors and it got to about 98% done before i accidently hit the power button and it didnt find any bad sectors. Next I ran Segate Lifeguard Tools or whatever. I ran the quick check and the sector test and they both came out OK. Then i noticed that it was detecting the NTFS partition on it, so I and the "File Structure Test". It says: "Eaxamines FAT and NTFS partition volume directorys and file information. The test determines of there are data file stucture errors on any partitions or volumes." It failed this test. I dont know what to do next. Some advice would be great. I havent tested anything with my 320GB harddrive. Thanks Guys.
