\"The wipefs family of functions first appeared in Mac OS X Leopard (10.5.3).Wipefs -a device. \".Sh HISTORY \" Document history if command behaves in a unique manner Sh BUGS \" Document known, unremedied bugs It is possible that some user data (or intact file systems in some partitions) may still be recovered.įunctions return 0 on success, or will fail and return an error code. This function is not designed as a means to safely delete all data. Although the partition scheme or file system on Represents a partition (e.g., /dev/diskXsY), only the file system in that partition is destroyed. dev/diskX), the partition map of the disk will be destroyed. This function destroys any file system or partition scheme on the volume represented by Ioctl and then writes data to the volume to wipe out existing file systems on it. If this function is called multiple times, the union of all the ranges provided will be excluded from being This function does not write any data to the Otherwise, some file systems may still be recognized on the volume. It is the caller's responsibility to write to these blocks. Optimizations if the caller will write to these blocks. Multiple times, the union of all the ranges provided will be written byįunction tells wipefs not to write anything in the block range provided. This function does not write any data to the volume. Separately, especially if the block range overlaps or is contiguous with other ranges that wipefs This may be more efficient than if the caller were to write this range This function does not write any data to the volume.įunction tells wipefs to write zeroes in the block range provided, in addition to any other ranges Is the file handle of the volume to be wiped, which can be a block device node, a character device node, or a file. It is possible that previous file system content could be recovered by other means. They only overwrite enough to make sure that the normal utilities will no longer recognize any file system content. These routines do not securely erase the previous content. These routines do not overwrite all volume structures. This is usually used by the newfs_* utilities before they create new file systems on the volume, so that the existing file system will not be mounted accidentally after the new file system is created. Then zeroes are written to various locations that are used by various file systems to recognize their content and mount their volumes. Ioctl is sent to the device to invalidate all of its content. The wipefs family of functions wipe existing file systems on a volume.
