It was said that nowadays, common file systems such as NTFS and HFS+ use a journaling mechanism so that when power is cut out or if there is a power outage, the hard drive is still in good shape and no scan disk is needed to restore integrity of the hard disk.
Is it true for external hard drives and USB thumb drives too? As long as it is using a journaling file system, then is it the same no matter what the media is?
