December 20, 201510 yr I just finished a pre-clear on an SSD. Here's the report. Is there a guide on how to interpret the results? This one looks like it surfaced a few new errors, but not over a SMART threshold? ================================================================== 1.15 = unRAID server Pre-Clear disk /dev/sdd = cycle 1 of 1, partition start on sector 64 = Disk Pre-Clear-Read completed DONE = Step 1 of 10 - Copying zeros to first 2048k bytes DONE = Step 2 of 10 - Copying zeros to remainder of disk to clear it DONE = Step 3 of 10 - Disk is now cleared from MBR onward.

December 20, 201510 yr Author Right, unfortunately, there appears to be a hitch in getting this information - until you've started the array. I'm not able to see the flash drive as a share until the array has been started. I started the array, but then the disks are not available in preclear (because the array started). I suppose I could start the array, then stop, do a new config, then only the flash drive should be active when I do the start array... right?

The flash share is the only share that is available with the array stopped. Also, disks not in the array are available for preclear with the array started. The whole point of preclear is to allow you to continue to use your server while you clear a disk.

December 20, 201510 yr Author Don't know what you are talking about. The flash share is the only share that is available with the array stopped. Yeah, its weird. I've got the server up and running, can access the GUI (IP address only!, not the server name), ran preclear on a couple disks using trial while I waited for the USB stick to arrive. It came today, I purchased the key and installed. I've setup Date and Time, Disk Settings, Identification, Network Settings, Network Services (SMB), set the correct Workgroup, etc... SMB Settings (both the same) SMB Workgroup - HunterNAS SMB Workgroup - HunterNAS2 The only difference is that HunterNAS2 has Local Master turned off. Did I miss something? I tried just typing the server name (//hunternas2) in windows explorer and it shows up, but DOES NOT show up in the Network panel. So very odd...
December 23, 201510 yr Author Quick bump on this one, not seeing the new server through SMB services.
