I've recently bought a Toshiba Equium U400-124 Laptop. It has Windows Vista preinstalled, but I want to install XP. I did the usual, inserted CD, booted up from it, but Setup said it did not detect a hard drive. I figured this was something to do with the SATA/RAID drivers, so I got DriverPacks and integrated them all. Even so, it still does not work. The hard drive manufacturer, Hitachi, has a different story. It says that the drive is compatible with Windows XP SP2.
Originally, the laptop had three partitions, one was the main C: drive, the D: drive was a 1GB recovery drive, and the E: drive was also some sort of a recovery drive. I used Norton Partition Manager to edit the partitions. It gave some errors. Then Vista only showed up the C: drive as 70GB (the HDD is 160GB). I am really stuck since I can't stand Vista. Please help. Hurry.
your right it is because of your SATA/RAID drivers...you need to go to Toshiba's website and look for your model laptop and download the SATA drivers for that system..
Normally they will want you to put it on a floppy disk and load it before windows setup (the part where is says HIT F6 to install SATA/RAID drivers" and you hit F6 and locate the floppy with the drivers...
its a bitch that you have to use a floppy drive I know...the only other way would be to add those drivers to your own custom XP copy...by way of Nlite....
i just finished working on a toshiba satellite a200 that had originally vista that i upgraded to xp pro sp2 with no problems. i think your problem is caused by the norton partition manager as i used xp to delete all the partitions & make a new 1. try that & see what happens.
