Today I tried to install my two Maxtor 40 gig ata 133s in an ASUS A7N8X using WIN XP PRO, was notibly slower than when on my old ASUS A7V8X, but worked the first time untill SP-1 was installed. Than when rebooting had several missing files. Tried to reinstall but now when formatting in NTFS it will get to 100% and stay there for about 10 minutes untill I get an error message saying unable to format. And if I chose the quick format it will never get beyond 20%. Also I have tried taking both drives out and formatted them seperatly in FAT 32 with no porblems. Any help would be greatly apperciated.
