June 17, 201214 yr This is my first time using unRAID, so I have a few questions about a server I am building: [*]I plan on using the free unRAID version, confirm my setup works with 2 drives (1 parity, 1 data). Once I need 4+ drives, I will register for a license. Are there any issues upgrading to a licensed version from free? [*]My main intention is to use unRAID as a Plex media server. Any big known issues with Plex on unRAID? [*]I just ordered two new 2TB drives (1 parity, 1 for data); do I need to run preclear_disk.sh on both? Is there an actual benefit? (I read the preclear page, but didn't see any description of benefits) Thanks for answering my questions!

Up to 20% of new disks are returned due to failing this test. It has the additional benefit of zeroing the entire surface and writing the unRAID all-clear signature. The signature allows new drives to expand an existing array without the extensive downtime that is required when unRAID clears the disk itself.
