Solve : HDD Undetected?

1.	Solve : HDD Undetected?
Answer» I have 2 internal drives. I shutdown the computer, Windows Vista, then pulled the power connector on the 2nd HD. Turned on comp. all worked fine. Shutdown and put power conn. back on 2nd HD, now it will not detect either HD or CD in BIOS unless I once again remove the 2nd HD power conn. Did I mess it up by not REMOVING IDE cable ? No Jumpers were touched, maybe windows thinks it's defective & will not recognize ? did you fiddle with any jumpers in the process?Are both hard drives on the same IDE ribbon?As you have been fiddling about with the BIOS I'm going to assume that the machine is still set to detect drives connected to it. I.e. Primary IDE is not set to None Present (should be set to Auto - [Easiest] or MANUAL - [not recommended for inexperieced users]) You could try disconnecting all the drives, check that your BIOS is registering all clear and then reconnect the drives one by one. So SATA first, SEE if it registers then the other drives. It's been a while since I've tampered with IDE connections do motherboards still have a manual option?The BIOS is easily confused and only one change should be made at a time... Sometimes a few re-boots are needed. There is also a built in drive detection tool in SETUP...have you tried this ? ?Quote from: patio on January 19, 2009, 07:06:19 AM The BIOS is easily confused and only one change should be made at a time...

I think what happens when no power is supplied- is the BIOS sends out the "Identify Device" ATA command- but since the drive has no power, it doesn't respond and so the BIOS moves on.

Thats what I just said.Hello, i am a new member here.

I am having a similar ISSUE to your one.

do you know what make or version your Bios is. you can do a google search for instruction manual.
then perhaps we can help more easily

my ide drive died, i bought a replacement that is a sata drive, and can not get my computer to recognise it.
do some boards shut down an ide channel when the sata is connected?Bigneil i suggest starting your own Topic so it can recieve the proper attention...Do not leave a device on a cable with its power off.
