Eassos PartitionGuru Free is an easy-to-use hard drive manager which can create, resize, split, extend, clone or recover partitions.
The latest edition can also format multiple USB keys simultaneously and automatically, without any user intervention at all.
Making it so easy to wipe storage devices could be a little dangerous, of course, but fortunately the program only wipes empty drives by default.
It’s also possible to define specific models to format, so maybe your Kingston will be erased while your SanDisk Cruzer is untouched.
In addition, you’re able to select a file system (FAT32, NTFS), cluster size and volume label, as well as checking for bad sectors or wiping all sectors to erase confidential files.
Once the appropriate rules are set up, all you need to do is insert a USB key. PartitionGuru detects it, checks for files, and if everything matches your needs, automatically formats the drive.
The program can even automatically eject the drive when it’s done, so all you have to do is insert each key, watch the status bar, and remove it when the process has finished.
Eassos PartitionGuru Free runs on Windows 2000 (no annoying dependencies here) and later.
