The CPU is not recognizing it
I have a SADA hard drive
I want to add a IDEE type drive
please use correct terminology. if you are unsure about what something is called, describe it, as incorrect terminology can cause confusion and lead us to giving you incorrect information. the CPU does not recognize anything, it processes information. also, there is no such thing as a SADA and IDEE harddrive, they are SATA and IDE.
with that being sorted out, i believe you meant to say that the computer does not recognize the new harddrive. have you formatted and installed windows on it? does it show up in the BIOS?
