Flash Disk Lock 1.7
Christopher
In our daily life, you often use USB flash drives. No matter you are a businessman, an employee, a student, or even a housewife, a USB flash drive and computer can assist you in your routine work. When you are enjoying the convenience of the USB flash drive, you may ignore the security of your device. So how can you protect a flash drive by locking it with simple steps?
In fact, Windows offers you a built-in tool to lock your USB flash drive files. All you need to do is to right-click your USB files and click the encrypt button. Follow the detailed guide below to lock your flash drive.
Step 6. On the Choose which encryption mode to use screen, select "Compatible mode" and then hit "Next". Then, you reach the final step. Pay attention to some warnings and click "Start encrypting". BitLocker will immediately work and encrypt your flash drive with a password.
Rohos Mini Drive password-protects a USB flash drive by creating a hidden and encrypted partition on the disk. This tool works well whether you possess admin rights on the target computer or not. Besides, it can automatically detect your USB flash drive and sets the properties for the encrypted partition. All you need to do is to provide a password to protect it.
The most recommended way to lock a USB flash drive is using EaseUS LockMyFile. This is a user-friendly USB flash locker, and even a computer novice can handle it. This USB locker can hide, lock, protect, and encrypt files and folders on Windows 10 and Windows 11. Besides, the theory to lock USB drives for USB Security is the most advanced 256-bit on-the-fly encryption technology. Key features of EaseUS LockMyFile are as follows:
Step 1. Download and install EaseUS LockMyFile on your computer. For the first time setup, enter a strong authentication password for use, and a valid email address for password retrieval in case you forgot the password. You can change the password anytime in "Settings".
Step 2. To lock files or folders on an external device, navigate to the "External Disk" section and then click "Locking File". Next, on the right menu, choose the "Lock File(s)" or "Lock Folder" option.
Now you know how to encrypt a flash drive with a password in Windows 11/10/8.1/8/7. This guide has helped you in locking and protecting your USB sticks. The need for USB security software is growing because such USB drives don't come with any reliable security algorithms. If you're worried about your USB stick corrupting and result in data loss, you can back up your USB data in advance.
- is there any kind of protection between the pad and the usb key itself ? I mean, i did not open the usb key, but I assume there is a kind of encryption between the pad and the stick itself as it sounds like to be glued over a standard flash disk reason of his size.
A: No but we will in a later version encrypt the data on the fly so it is more secure. IE in other words if someone takes the memory chips and installs them on another unit that is exactly the same they might be able to read the data on the drive. However. 90% of the time the unit would be destroyed to do this type of swap as the housing is bonded to the PCB.
The manual has instructions to set the device to "always unlocked" mode. After this mode is set (which the manual does state can only be done from an unlocked mode), and you re-lock it, the PIN can be different from the initial PIN, correct?
A: Honestly I have not personally sat down and done the math but that sounds about right I am not sure if there are any other limitations that I am not aware of but I will check and let you know if this is not correct.
A: The delay is hen the password is set, or in other words once you enter the pass word you have 15 seconds to confirm it other wise it will not be set, and you have 15 seconds to enter the pass word or it will not unlock. The delay starts when you enable or start the lock/un-lock process.
I was not correct, the device will always give you a 15 second delay before it locks. So if you remove it and insert it with in 15 seconds it should stay unlocked. As long as the green light is blinking when you move the drive it will stay un-locked.
I'd have to view the 15 second window as a security hole via physical social engineering. It makes sense to have a delay long enough where if it falls out of the USB port (unlikely) or gets taken out, only to be put right back in, you don't have to unlock it again (in otherwords it's a good user function feature), but this 15 second window does open up opportunities for unscrupulous people to get access to your info. However, the window would only be opened by fault of the end user, but then this comes back to social engineering forcing said window open.
As a counter-action against this, you can still encrypt the USB stick via the freeware tools already posted around here, correct? Assuming so, is the software still on the USB sticks, or is it a separate download?
If it fails in two years we will replace it, the expected life is 3-5 years but will depend how you use it. And if it is locked when the battery fails you can still just plug it into a system and the system will provide the power to activate it.
You can use Sysinternals Process Explorer to find the handle for any files that are open. Just select the Find menu and select Find Handle or DLL. In the dialog that opens enter the drive letter into the search box. The search results should show all of the files that are open from the drive and which process has them open.
Native Method: Windows (10 at least, AFAIK) creates an entry in the event log when you try to eject a removable drive and you cannot because a process has a lock on it. The two Event IDs 225 will show the process ID and the name of the process responsible for the lock.
Take appropriate action. Ending a task gracefully (closing the program that has the lock) is OK most of the time. Stopping the Windows Search service is also ok. Stopping an antivirus scan should be ok (if you don't suspect you have any viruses at the time). Going into the task manager and killing the process might not be ok. How to deal with this is beyond the scope of this question.
UPDATE 2018: I've seen applications such as WhatsApp Desktop keeping handles on Chrome Canary via the System Process. Since you cannot eject the boot disk (beacuse it is in use), the solution was to use another nifty Sysinternals utility, called Handle. After you close the program which has the locked file, launch handle and run (as an example) handle64 "Chrome SxS\Application\chrome.exe" to see if the handles are still present on the file that has the PID 4 lock. Via trial and error, close each program running, until there are no more handles on the locked file.
UPDATE 2022: Microsoft's handy PowerToys now includes an extension to check which process is locking a file/folder. It is called File Locksmith and it is a free download. Although you can customize which PowerToy feature you want to enable, if this is the only one you will use, it's an overkill. Better to use a dedicated tool for the job.
Download and run SafelyRemove, by the same people who make LockHunter. I am not sure why they charge for SafelyRemove when their free LockHunter already does the job. But it helps you eject the drive and if it can't do it, it displays which processes have a lock on it:
The output will list all instances in the past hour where the system couldn't eject a disk drive. The Message column shows the process that blocked ejection. In my example below, task manager was actually the culprit and I was able to eject after closing task manager.
You can start resmon.exe (through WIN+R), go to disk > Disk Activity > Sort by FileNow you can see all files being accessed by the system and which processes are accessing them, ordered by the file path (which btw starts with a drive letter).May not work with all cases, but it's a simple approach.
Restarting the computer seems "free up" device usage.Also for faster removal, you can disable windows caching on Hardware section of your device, sometimes windows will take longer than expected to flush the cache to external disk and will display that message saying that the device is in use (because it will be, by Windows itself)
If you open "My Computer" and your drive is not listed under the "Removable Storage" headers, then Windows is viewing it as a fixed system resource for some reason. You will have to unmount any partitions on the drive.
If this is the case, open "Computer Management", then go to "Disk Management". For each partition on the device, right-click the partition, select "Change Drive Letters and Paths", and remove any drive letters assigned to that partition. Once you do so, you should find that the "safely eject" feature works as you had hoped.
This is similar to Jon's answer, but Get-EventLog is part of the old Win32 API and isn't supported in powershell-core. Get-WinEvent automatically sorts chronologically (descending) so no additional sort is needed, either.
Under Resource Monitor, column named image is used to display process name and column named File can be used to check whether the process is using your drive. E.g. File address would be F:/foo/bar.tmp then if your attached usb have Drive letter F:, you can terminate this process. column named PID is showing the process ID.
When I plug in my USB flash drive, it shows up on my computer as write-protected or read-only. I am unable to transfer data to it, nor can I modify or delete any files already stored on it. I also cannot repartition or reformat the drive using Windows Disk Management, DiskPart, GParted, or other tools. The drive does not have a write-protect switch.
