Posted on 1998-07-14
Last Modified: 2011-09-20
I installed a new HDD, and as i go into CMOS/BIOS to detect it, everything is fine. Then when i went into windows it wasn't in explorer so i tried add detect new hardware, it didnt find anything in it's search either. I even went into DOS to check for it and nothing new was there. Could someone please tell me what i should try next?

You must first partition the drive using FDISK and then format it, for Dos/Windows to recognize it.
Let me know if you need more info.

When you run FDISK, can FDISK see the new drive?  Have you gotten that far yet?

If you don't need the data on that disk, you are best to FDISK and reformat it.  As long as it is detected properly in your CMOS before you start FDISK stuff you should be alright.  You want to be sure your select the correct drive to FDISK also!

Let me know if the fdisk was the answer as I beleive I mentioned that initially.

If you want to save that data, before you fdisk & format:
1) How are the drives set up on the computer? (Master, slave, Primary IDE port, etc.)
2) What Windows version are you currently running?
3) What version of Dos or Windows was on the drive which has been partitioned earlier?

Remember that versions prior to Win95B cannot access a drive that has been set up with FAT32.
Let me know if you need more.
