# Validating a Drive

The drive validation process ensures that the drive is functioning properly by mounting a media, writing on the media, re-winding and seeking data and then reading back from the media.

It is recommended that a drive validation operation is performed after configuring the tape storage and before performing a data protection operation.

Drive validation can also be performed to check the throughput of the device. In addition, you can verify whether different tape block size is supported by the hardware and operating system, by performing a drive validation operation.
