Any assistance would greatly be appreciated.

Like many of us on here, I too have TB's of info on my PP2 R8 (4gb each bay)

I replaced a busted drive. my 5th or 6th in 4 years on this specific tower. I really don't know if that's good or not. 

But that's besides the point. 

My issue today is that the computer cannot read the disc/disk after the swap.

Most places I searched on suggested that I backup and reboot/restore the drive. 

Two things with that:

1. I don't know how to get into pegasus2 to back it up, could someone help guide me to a step by step on how to do that?

2. Is there another way - a way to possibly override of the notification "The Disk You Inserted Was Not Readable By This Computer"?

Also I opened the promise utility - and all seems fine.

Again, I would be extremely grateful for any help.

Hi Cliff,

Please click on "Ignore" option on the prompt.

Once that is done, please follow the below steps to start the rebuild on the drive.

- Click on "Physical Drive" list in the Utility and make sure the replacement drive is showing up in the list 

- The status of that drive should be "Unconfigured" 

- If the status is "Passthru", then unlock the Utility and click on settings for that drive and change it to "Unconfigured"

- Confirm the settings .

- Then click on "Background Activities"

- Click on the Start button next to the Rebuild.

- Select the Source drive and the Target drive and Start the process.

- It will take 3-4 hoursto complete the process and you can see the progress in the bottom.


Thanks !
