hi, i have a internal 1tb seagate hdd. i put it in my computer about a week or 2 ago and since then it has been choosing when it is seen in my computer and disk management. bios always picks it up but windows dosent, its not a boot drive and it was formatted in NTFS. however when i run a ubuntu boot disk it sees it but says the disk is in secure mode. i used magic partition to reformat it and it had to unlock it and such left it to format and it worked but now it has done it again and i don't know why. the partition magic disk will work but it seems to be a temporary solution. and i don't want to keep losing my files. im running windows 7 btw.
