Hard disk not recognized?

[BlackScarletLove]

I have a hard disk that I want to clone my C drive to, and I connected it via USB external; it showed up fine, I formatted it. However, since XP doesn't recognize boot drives through USB I wanted to attach it internally before I cloned my system drive over for when I do a boot test.

However, the drive that showed up just fine through USB isn't showing up when I plug it into the MB. It is recognized and is powering up, because when the system posts, the initial screen shows it is connected, and it gets warm after a few minutes, so it's working and the system can detect it, it is just not showing up in Windows.

I checked, and it's set to Slave.

What's the problem?

You might want to check the disk manager in Windows to make sure its assigned a drive letter and is active.

You have to partition a drive after formatting it. But that should have made it inaccessible on the USB also.

You need to recheck BIOS settings! try to enable/disable some setting there in BIOS set up. I am sure it will help you. Let me know, if it works.
