So I set up my NAS drive with two 1.5T seagate drives running in a raid 1 configuration.  I have an extra HD as a spare (exact same model for all three drives).

I'm not familiar with tryinig to recover from a failed drive on my dlink nas drive (I have both the 323 and 321).  So when I get a confirmation that a drive has failed or the nas is running in degraded mode, this is what I am going to do (please comment if you see things that don't make any sense).

Once I get notified or notice one of my drives is running in degraded mode, I'm going to do the following.

1. back up my dns-32X with a USB external HD.  If one drive is degraded, I should still be able to access the data on the NAS.
2. turn off the NAS drive
3. pull out the failed drive (I assume i'll know which one from the alert warning or status page, right?)
4. insert the spare 1.5T drive
5. turn on the NAS
6. log into the NAS and rebuild the drive and wait a day.....

Am I on the right track? I figure I should ask these questions now before the eventual failure of my drive.  These 1.5T drives do not have good reviews so I best get my act together now .

Thanks,
Gary

1. back up my dns-32X with a USB external HD. 

This should be a permanent fixture.
I have mine on monthly backup/one way sync, others have it on daily backup. There are many ways to set up your backup. But you really should have some sort of plan, not just rely on RAID 1 with a spare hard drive.

Maybe use the spare drive as your backup now and if a drive does fail you can still use it as the replacement drive after you have bought a new 1.5TB and transferred the backup over(there would be better ways than this, this is just my first thoughts thing that popped into my peanut)

About the correct method of replacing the failed drive I will leave to someone that has more experience on the DNS-323

Just my thoughts about beating data lose.

From the D-Link support FAQ available here

How do I restore my RAID1 settings if a drive has failed?

 Note: If a RAID1 drive has failed, the DNS-323/321 will display the HDD LED light, of the corresponding drive, in Amber and you will receive an email from the DNS-323/321 stating a drive has failed if this option has been configured

If this happens, follow these steps to restore the RAID1 settings:

Step 1: Power down the DNS-323/321

Step 2: Remove the failed drive from the DNS-323/321

Step 3: Insert the new drive into the DNS-323/321

Note: The new drive Should be blank with no partition on the drive The drive may still be detected and prompt to format if formatted in NTFS

Step 4: Power on the DNS-323/321

Step 5: After a minute log into the DNS-323/321 web interface

Step 6: You will be prompt to format and resync on entry, click OK

Note: Formatting a hard drive will erase the data stored on the hard drive. Please backup important data before formatting a hard drive

Note: This action will format the replaced drive only and sync the two hard drives in RAID1

Step 7: Wait for format and resync to complete. The DNS-323/321 is now ready for use

It's been my experience (in simulations - I haven't actually had a drive fail) that you may not see an amber LED, it may be off or a pink/purple/white color, and this has worked for me although I have read of many instances where other's have been less fortunate - that backup before you start maybe turn out to be of vital importance.

I have heard of instances where the unit has formatted the wrong drive. Best to backup to external usb drive before anything else.

I'm replying to your post fordem where you say:

Someone on this forum was pissed it formatted the WRONG drive!

User beware .

Actually I'm not the one saying that - it's direct cut & paste (and quoted) from the FAQ.
