Validation ensures all the data on the volume is still readable.ĭuring validation, SoftRAID reads every block on the volume-making sure it can be read without errors. If you’re ever worried about the integrity of your SoftRAID volume, you can Validate it at any time. (It’s not possible to restore data from a card that’s been certified as the data has been overwritten with zeros.) However, always remember that certifying will erase all the data from your drive, so be sure to back up your data first. In addition, the more you write to an SD, the harder it is to find ‘clean’ areas to write to.Ĭertifying your SD card will fill the memory with zeros, essentially ‘erasing’ all the data, and making it behave like new. When you need to write to these previously used sections, data has to be erased first, slowing the process down.
SSDs that don’t use TRIM (such as all USB flash media) get slower the more they are used, because instead of actually erasing old data, flash just labels those sectors as “clean”. It’s a good idea to regularly “revitalize” or “recondition” your SD memory cards, and SoftRAID’s certify can help you do that. Use certify to “revitalize” your SD cards Remember to use at least 2 certify passes 3 is even better. Whether it’s an SD, SDHC, or SDXC card, SoftRAID will let you know if your new card has any bad sectors on it that could put your data at risk. You can use SoftRAID’s certify feature to test new SD memory cards before you use them in your digital camera, video recorder etc. SoftRAID doesn’t just certify rotating drives. On Thunderbolt buses, certifying 4 – 8 disks at once takes only slightly longer than certifying a single disk. After you have certified a disk, you know that it can safely and reliably store your files. If you don’t take the time to certify a disk, you run the risk of losing all the data you put on it. Certifying a large disk with SoftRAID can take a long time-often a day or two (or more)-but it’s worth it!
