These days, "quick" formatting means merely recreating the filesystem metadata (a small fraction of space on a typical particion) while "full" formatting means the same plus scanning the blocks to detect those which are "bad" (unreadable) -- a feature which is hardly needed on today's hardware which performs internal remapping of failed sectors. See [1] for more info. Hence the only way to ensure safety is wiping disks (which is typically done by filling all addressable space on the drive by random (or specially cooked) data, several times). 1. http://support.microsoft.com/kb/302686 -- You received this message because you are subscribed to the Google Groups "Git for human beings" group.

How do I do this? At the least, "reformat" the disks to destroy *all* the current files, because many places on the disk is evidence of past activities. You need to be more careful if the information you are trying to remove is truly valuable to outsiders.

By the way, this thought crossed my mind as well when I was writing my response. EULA explicitly prohibits relicensing, so yes, while IANAL, I concur that consulting legal department would be a good thing. -- You received this message because you are subscribed to the Google Groups "Git for human beings" group.

Thanks As to Git bash, the answer is "most probably yes" because bash saves the input history to a file under the user's home directory (and you're probably deleting the user profiles [1]). As to Conemu, the answer is also "probably yes": "native" Windows software tends to use registry for storing all kinds of random stuff, including history, and contemporary programs would store this data in a personal user's registry hive (which is just a set of files under the user's home directory) so if you're deleting user profiles [1] you're deleting this data as well. Looking at the issue from another perspective... does knowing URLs of those repos give away that much to a prying eye? What matters is repository contents not where that contents is located. If you have some private repos accessible publicly then have them properly protected -- say, by using SSH keys, and have these keys properly maintained. Note that if you're absolutely paranoid (and you might have reasons to be [2]), you have to wipe (and I mean it, not just format) hard drives and then install Windows there (either from a rescue partition/DVD if you're using whatever the vendor installer or from your own images). If the buyer does not care much, installing FreeDOS after wiping could be just fine. It really depends on the expectations. [1] If not, you really have to. [2] When you're deleting an object from the filesystem, the object's data stays intact and can be recovered using specialized software unless it happens to later be overwritten by other filesystem operations (typically -- storing new files). Google for "TestDisk" as one popular example. -- You received this message because you are subscribed to the Google Groups "Git for human beings" group.

[git-users] How to clear history of all repo url that has been accessed from local machine?
Hi all, My company is upgrading the laptops and so, they're selling the old ones. The problem is, we've been using the old laptops to access remote git repos and the employer would like to clean all possible traces of repo URLs that have been accessed in these laptops. How do I do this? We used Git Bash and Conemu. Will uninstalling Git Bash and Conemu be enough to delete all repo URL history in the laptops? or are these repo URL never been saved to local disk in the first place?
