this is my first post anywhere! to do this right, i would like to know where to post my question and how to include the Everest report on my sys specs...if this is nec. my question is much discussed, but i remain confused and dont want to do any irreversible damage by acting without asking? i love my computer...y'know? so, here it is - i have a single seagate sata drive (100 gb) on an hp pavilion dv2025nr ("designed for windows xp/vista compatible") running xp home sp2. i have done a factory restore from the recovery partition and the problem still remains the same. that is... the hdd is only recognized every fifth boot attempt. strange! here's how it goes...i shut it down thru the start menu, push power on, get blank black screen, push power off, on again, get hp screen where you can enter setup, wait, it goes to blank grey screen with blinking cursor and flashing words "os not found," power off, on again, blank black screen, power off, and then, IF AND ONLY IF I WAIT ABOUT HALF AN HOUR, power on and xp comes on just fine. this is consistent, but very inconvenient! help, please! dont know if you want to know this now, but redirect me as nec... dev mgr (IDE/ATAPI Controllers) has: nVidia Serial ATA controller Primary IDE CHANNEL Secondary IDE channel [3 ricoh mem card things] Standard dual pci ide controller i dont mind the idea of trying to run the sata hdd as ata or in ide mode or whatever that option is (sorry i am so clueless) but i dont know how to do that and the bios is only a partial build so i cant disable sata control. thanks so much!
