Hello All, I don't mean to hijack this thread but the topic has got me wondering if my normal HDD format/clean routine is enough. Usually a family members pc becomes bogged down/infected at some point and I'm the one thats called to come fix it. In the case of a viral infection that does more damage then I'm able to repair or the unavoidable user screwup that brings the system to an unusable state it comes time to do my usual HDD format/OS Install and so on. - Check if any important items are missing from backup. (normally this isn't an issue) - Insert Vista Disc, Select repair computer, launch Diskpart from command prompt and delete all partitions. Then do a Clean All pass before recreating the OS partition with a full format and then proceed to do an OS install. Is an HDD Secure Delete/Wipe App such as DBan something I should be using for 2-3 passes to remove anything left on the drive to clean out the drive? When would be the appropriate time to use an app like dban? Thanks.
