Until its clusters are overwritten by other files, it can theoretically be recovered, and if there is a lot of free space, then it could take a while before it gets overwritten-of course if you are actually trying to recover an accidentally deleted file, it is likely to immediately overwritten even with plenty of free space (аІ _аІ ). Instead, the system only marks it as deleted and its disk-space as free for use by new files. However, for performance reasons, permanently deleting a file doesnвЂ™t actually delete the file. Therefore, if you delete a file in Windows from a hard-drive with just Del instead of в‡§ Shift+ Del, you should be able to restore it from the Recycle Bin, but deleting a file from a removable media with Del is the same as using в‡§ Shift+ Del to permanently delete it since it has no Recycle Bin. This is because Windows only puts a Recycle Bin on fixed volumes like hard-drives, not removable volumes like flash-drives, memory cards, floppy disks, packet-writing CD+RWs, network drives, or substituted drive letters (even ones mapped to fixed-disks). What they were likely talking about was that deleting a file from a flash-drive is always equivalent to holding в‡§ Shift when deleting the file. Yes and no it depends on your definition of вЂњgone for goodвЂќ. I heard some people mention that files are deleted from flash drive for good, there is no tracing back. However, hitting things with a hammer is so much more fun and permanent. You could also cipher /w a few times on a Windows machine ( dd if=/dev/zero bs=2048 of=/mnt/disk/file on a *NIX machine). Flash drives are cheap and yes, data can be recovered from them.
