Make sure the C drive is selected as first in the boot order in the BIOS.
Does the D drive power up when the computer is turned on? You probably need to take off the cover so you can hear it...

So this problem is solved?
The F6 trick is required to use SATA drives on most older boards.

Is that a SATA drive?
You need to "Press F6" during the install to install the SATA drivers.

Doesn't look good. If you're sure you can't see it in Disk Management, it's probably toast.

In all cases I've seen, an external drive must be set to master. This setting is usually clearly marked on the drive, so don't guess.
Once you've got the jumper set correctly, look at this drive in...

You may be able to get some help from Dell by emailing that code to them.
You could also remove the CMOS battery, or look here:

Dell makes excellent hardware, and their support is usually pretty good. You may need to be more patient.

FWIW-You can buy a case and use the SATA drive as an external.

Is this XP?
You need to install the SATA drivers (See "Press F6") during the install process.

It doesn't seem likely. The internal interface is SATA, and I doubt there's any way to adapt it.

When it starts clicking, it's basically toast.
The lesson here is the same one we've all learned the hard way-backup, backup, backup.
Good luck.

You don't need the freezer yet, and you may damage it that way. The freezer method works only rarely, and you should avoid the person who suggested this.

I'm saying remove the drive from the case-it's very often the case that's at fault, not the drive.

Get an external drive and backup to CD/DVD as often as is prudent.

It's very possible this is just a failure of the electronics in the case.
Remove the drive and attach it with a USB adapter and see if you can access it:...

Modern computers don't care what device is on what channel.
The only caveat I know of is that data transfer is faster between devices on different channels.

Please start your own thread to avoid confusion.

Most likely, but you'll have to reinstall Windows, or at least do a repair install.

Rt-click on the rectangular space next to the drive name to get the format option. It probably shows as "unallocated".
You can also format from the command line.

There's no problem that I know of, except to exercise care not to mistreat the drive while moving it around.
You might find a 2.5" portable more convenient.

I don't think so. The boot drive must have the windows OS on it. You'll need a floppy drive to make this work. (Press F6 to load driver).

I applaud you for having the curiosity to try this.
You probably need to remove the partitions first.
Open disk management and rt-click to delete the existing partitions, then re-create.

This will make more sense when you've had a couple of RAID failures, as I have.

Format is fine for most cases, unless you have nuclear secrets or the formula for coke.

Your ports are shown in the manual as SATA 1 Primary, Secondary) and the same for SATA 2(P,S).
Again, the manual isn't clear, but I'd assume these ports are adjacent.
I should also mention that you...

The manual just isn't clear about this.
Try connecting both HDs to:
The same channel.
Different channels.
How are they connected now?
It's possible you need a BIOS update.

Look in the BIOS under "Integrated Peripherals" and make sure the SATA secondaries are enabled.

Is there a RAID setup involved? What's the BIOS setting for these ports?
My board has 4 SATA ports, but doesn't support SATA Optical drives.
I can't tell from your manual whether yours does or not.

Motherboard model number?

It doesn't matter hiow you connect the new drive as long as you can identify it.
You'll boot to the Data Lifeguard disk and do a 'From:To" operation which is pretty automatic-just be sure the drives...

Get the appropriate Data Lifeguard software from WD and clone the drive.

Some games should be fine, but others will be slow.

If XP, try recovery console. Fixboot may solve your problem.
