Always certify a disk before using it
Most modern disks only receive limited testing when they are manufactured. They are tested to ensure that they can start and stop reliably and that they can read and write to some small fraction of the sectors on them. You should not trust your valuable work on these disks until you know that all of the sectors on them can reliably store data. Otherwise, you might write out an important file to a volume on the disk only to discover later than you can’t read it back.
You can test all of the sectors on your new disk by using SoftRAID’s disk certify function. This will write out data to every sector on the disk and then read it back to ensure that it is reliable. After successfully completing a multi-pass certify on your new disk using SoftRAID, you can be certain that it can store your files and read them back correctly.
