Secondary HD not recognized after new PSU install.

[yooniecorn]

My secondary SATA HD is not being recognized -- by the BIOS or by my OS -- after I installed a new PSU.

It can't be a drivers issue, as my main HD is also a SATA.

I changed the cord, and the port a few times. Connections look fine...

XP doesn't recognize it as 'new hardware', either.

Any ideas to try?

I hope I haven't lost all of my data...

EDIT: In addition, my attempts to ENTER the BIOS, and the RAID/SATA page both froze up my computer entirely -- the first, before it even loaded, and the second, once I was within the menus, and had triggered a key to open a secondary menu.

Can you startup and enter BIOS OK when this SATA is not attached?

No luck -- I tried both:
A) Removing the SATA cord, and leaving the power cord.
B) Removing both.

I am presuming that since you cannot get into the BIOS setup that you cannot now get into Windows either. If that is so then it sounds possible that you have faulty hardware causing a failure to POST and need to consider a bare bones boot (http://paulski.com/zpages.php?id=1718). Before dong that and if you can get into the Setup but it causes a freeze maybe try resetting the BIOS by removing all power to the PC and then removing the CMOS battery for 10 mins.

Actually, Windows works perfectly fine.

It only causes me trouble if I try to enter BIOS, and obviously, the secondary HD is not recognized.

Then it could still be a BIOS setting (such as the need to enable the drive's port or the need to enable it in one of a number of different modes). Sometimes recognition is affected by trying to run 3.0 speed drives on 1.5 speed host controllers without having jumpered the SATA to 1.5 speed. Check the jumper and also see if any bootable DOS based utililty (from floppy or CD) such as BiNG (in my sig) can see the drive. If it can be seen from non-plug-n-play DOS then the BIOS recognition is OK and it probably is a drivers issue. Some boards have more than one type of host controller.

I appreciate your input.

How could it be a drivers or jumper issue, though, if it worked perfectly fine for years before installing this new PSU? This isn't a new set-up, and the only new factor is the power supply.

I will try BiNG, thank you.

Either the power output from the new PSU is inadequate maybe (particularly since you cant get into the BIOS normally) or the SATA (or a host controller) got "taken out" when the old one failed or the new one was installed or co-incidentally.

BiNG should determine if it is a BIOS issue. Trying the drive in a USB enclosure or via a USB converter cable or in another PC should sort out where the specific problem lies. It seems quite likely that the drive and/or its cables/connections are faulty.

If the old PSU is still functional then see if replacing it allows recognition to happen as before.
