Re: Mobo wont recognize hard drive
Removing the battery only clears the settings in the bios so that won't really help.
When in the bios, just look for anything that says the model of the HD, if anything is there than it's been detected.
I think the problem is your hard drives OS, is currently configured with drivers, information, etc... about your other computer. Thus when you try to start it up on the Dell, their is a mismatch of the drivers, information of the system.
If you have a window's disk than maybe you can do a repair of the OS, maybe that will help. However it's better to have the hard drive formatted and start fresh when putting it onto another computer, so it doesn't have old information which could cause problems later on.
