So I added a new hard drive (powered down, assigned it, started the array, and waited for it to install the new drive) and now all my drives say unformatted?

 

Did I do something wrong or should I hit the format button (I've attached a picture below)? Kind of scared of losing all my data. Thanks for any help. 

Which of these is the new drive? Definitely do NOT hit the format button if any of those drives have data on them.

 

Are you sure you haven't left anything out in your description of what you did?

 

Post a syslog

Do not hit format. You will loose all of the data on your array.

 

Did you preclear the drive before adding it?

 

Stop the array, take a syslog, post it.

 

You are using a very old version of unRAID with known defects. Suggest that you upgrade after this issue is resolved, to 5.0.5.

 

 

Here is my syslog. My new drive is the last drive, drive 7.

syslog.txt

I would do a power down and reboot.

Okay, powered it down and now it looks okay. I think it's safe for me to hit format? Posted picture below, new drive is drive 7.

Yes. unRAID will report a drive as unformatted if it fails to mount the drive. Although being unformatted is one reason a drive would fail to mount, there are other ones. Clearly you hit one of the other ones. But had you hit format, it would have gladly formatted every drive in your array. No recovery would have been possible without using reiserfsck, which although effective much of the time, is not something you would enjoy and the results would likely be less than perfect.

 

As I said, update  your array to at least 4.7, but you really should go to 5.0.5.

Thanks for everyone's help. I will try updating later tonight.
