I am also having a problem with harddrives, I bought a 160GB Maxtor in Jan/Feb of this year, and I partitioned it to 3 different sizes. Anyways, recently I had formatted my PC and when I installed the new copy of Windows XP all of the files on one partition went bad and said I didn't have access to open them and such (administrative rights). So I went into Safe Mode to change these settings to allow me to use the files stored on that partition and when I came back to Windows XP in normal mode all the files were gone and the drive was empty and had full space. Overcoming my anger, a few days later I started using that partition to store files again, this time I got another error and had to format that partition. And now sometimes when I reboot my PC I get errors from that partition and I format it again, hoping it will fix it, but it only gives me the same error a few days later. Hopefully that all made sense and someone can help me!
