I should clarify that the second phase, reading sectors, is used to confirm the writes were good. Writing can be "successful" without actually being readable. This is why I like badblocks, it writes a series of patterns to each sector, and reads them. Multiple chances to clear up a bad block that way, and the patterns test each sector's magnetic storage capabilities.
