February 1, 201016 yr A few weeks ago my unRAID 4.3.3 box crashed...hard. I tried logging onto the box to gracefully take it down, but no luck, so I finally had to pull the power cord. When I tried starting it back up, however, one of my Promise SATA300 controller would balk and the bootup would never complete. Luckily, by powering off one drive at a time (my four-on-one drive enclosures made this step easy), I was able to isolate the problem to a single Seagate 500GB drive. I've now replaced the old defective drive with a relatively new green WD 1TB drive and brought my unRAID drive back online. All the drive indicators are green with the exception of the drive I just replaced, which is blue. I seem to have two choices: 1. Start or 2. Restore I want to keep all the data I had on the drives previously, just rebuilt the data that was on the defective drive. Which option should I choose? Thanks.
February 1, 201016 yr Press "Start" It is the ONLY way to rebuild onto the replacement drive. If you were to use the button labeled as "restore" you would immediately save a new disk configuration and immediately invalidate any previous parity calculations. It is actually a "Initialize Disk configuration" button. In other words, you would throw away any ability to restore any data as you just would have asked the server to FORGET any parity it had in the past and calculate new parity when you subsequently start the array. So... Just press "Start" DO NOT PRESS RESTORE... Not unless you do not want the data on the old disk reconstructed on the new. Joe L.

So... Just press "Start" Do newer versions (4.4 or 4.5) have more descriptive language? I now understand the difference between "Start" and "Restore", but it's not touched on very heavily in either the official documentation or wiki under the section about replacing a failed drive. And by Glimmerman911's post, I'm not the only one who found the verbage on the front-end gui lacking....
February 1, 201016 yr Do newer versions (4.4 or 4.5) have more descriptive language? The GUI looks still the same. There are some nice performance improvements under the hood though.
February 2, 201016 yr Author Thanks Joe L. Start is now underway.... Thanks again. Looks like unRAID rebuilt my data on the new drive without a hiccup, so I'm back up & running.
