Most flash drives have a slider that lets you change its locked state while it is not connected to anything. The other thing to check, especially for any of 8 GB or more, is if it was formatted ExFat at the factory. If it was, you'll need to upgrade to 10.6.4 or later or reformat it for the Mac alone to be able to use it. ExFat is only supported on 10.6.4 or later.
Some models of flash drives, memory cards and external drives can have switches to enable write protection. Most often you can find such switches in SD cards. Examine the device carefully and check the position of the switch (if there is any).
BitLocker is a full-disk encryption feature included with Windows 10 Pro, Enterprise, and Education editions. It encrypts the entire drive, including the operating system, user data, and applications. It can be used to unlock a protected drive by entering a recovery key or password. It also offers additional features such as two-factor authentication, auto-unlock, and PINs.
Yes, you can unlock a protected drive using the Command Prompt in Windows. To do this, open the Command Prompt by pressing Windows+R and typing "cmd". Then, type "manage-bde -unlock X: -password" (where X is the drive letter of the protected drive) and enter the password for the drive when prompted.
Disk Management is a Windows utility that allows users to manage their hard drives and other storage devices. It can be used to create, format, delete, and resize partitions on hard disks. It can also be used to assign drive letters to partitions, change the file system of a partition, and unlock a protected drive. To unlock a protected drive, right-click on the drive in Disk Management, select Change Drive Letter and Paths, and then select Remove.
I need a methodology described to do it manually if there is no safe way to obtain a good utility. The Sysinternals tool seems too complicated, if I don't understand at all, how to use it. Logoff/Logon does not work. Even disabling antivirus (Malwarebytes Pro and Microsoft Security Essentials) does not help. This is both using an external hub and using the onboard USB ports.
This with SD Card Adapter, USB sticks, USB-HDD, etc. Help!I am using Windows 7 Professional 32-bit. Should I pull it out while logged off? How would I know it has been dismounted/ejected? But it is grabbed immediately after I log back in.
@fixer1234: I have corrupted USB flash drives by just pulling it out anyway. If terminating a process has the same effect, then how does Win7 actually ever make USB obey the request to eject (which it also has done in the past)? If it's been there for hours, and after refusing to "eject" I close ALL apps and close the AVs, and Log Off, then Log On, it still refuses.
To your question "Is there a particular situation you're trying to fix or do you need a general purpose way to terminate any active process, release the device and eject it?": The whole point is to right click on the USB in SysTray or Devices & Printers or even Explorer, to just eject it properly.
@Richard: since the whole malware wrapper thing is spreading and sometimes by the site and sometimes by the dev themselves, I have had problems long ago with conduit and other sites. If I try Unlocker I will be needing to back up and make a comparison after, of the differences in the Reg and Temp files, and everywhere else I can think of. To just go ahead and trust them like I'm their puppy can be fine, or can cost me dearly.
You can use Process Explorer to close handles that might be preventing you from ejecting the drive. The easiest way is to search for the assigned letter to your drive then right click and close the handle(s).
Safely Remove has never worked well, and Microsoft will probably never fix it. If the drive won't let go, just put your computer to Sleep, wait about 15 seconds till the USB drive light stops flashing, and then unplug it.
Some portable drives include a lock switch that protects the drive while in transit. Insert the USB in your computer and test to see if you can save new files to the drive or edit anything located within the drive. A locked drive will show the files but will not allow access. It will typically return a notification telling you that the drive is locked and you do not have permission to access.
If it remains locks, check the drive for a switch. Push the switch to the opposite position and attempt again. In many cases, this simple switch will unlock the drive and make it available for normal use. The switch location varied by manufacturer. Some are very obvious buttons on the top of your drive and others are smaller and located on the sides. Most lock switches are color coded for easy locating.
Unlocking a write protected flash drive is surprisingly easy unless the drive is actually password protected by another individual. In this case, you will need permission to receive the password and enter the drive contents.
Insert the USB drive into a free port on the computer. Click the Start button on the desktop task bar. Select Computer from the Start menu. This displays the Computer folder that contains a list of all drives.
Right-click on the USB drive icon, then select Properties from the context menu. Click the Security tab on the Properties dialog box. Click the Edit button. This displays the USB drive permissions in the pane in the center of the dialog box.
Keep in mind that you might need to enter your Windows administrator password to unlock the drive. On home computers, the administrator password is usually the same as the main user's Windows login password. If you own the computer and the drive, this is quick and easy to accomplish.
When a USB drive, SD card or storage disk is write protected, there is often a good reason. The protection prevents files from being deleted or manipulated. Only unlock the drive if you actually have permission to enter and change the files and settings.
A drive that is owned by another individual requires explicit permission to enter the drive. The drive and the contents within the drive are the property of that individual. Manipulating any copyright files or files with legal protections can also qualify as illegal.

DI-2108 High Speed USB Data Acquisition and Data Logger System with Windaq software and 32GB USB flash drive. Features 8 differential analog input channels, 12 to 16-bit measurement resolution, a full scale range of 10V, and stand-alone data recording to removable USB thumb drive. Includes a DI-2108 instrument, a 6-foot USB cable, a screwdriver for signal connections, an NIST-traceable Calibration Certificate, and a 32GB USB flash drive with WinDaq software (downloadable at run.dataq.com) and the Calibration Certificate (.pdf).
Model DI-2108 delivers premium analog performance at a surprisingly affordable price. Eight analog input channels provide differential measurement flexibility and a 10 V full scale range. The differential input configuration provides noise rejection, easily adapts to singleended signal sources, and is protected up to 50 V dc or peak ac so that inevitable measurement mishaps will not harm the instrument. The front-end feeds a flexible resolution analog-to-digital converter that ranges from 12 to 16 bits as a function of sampling rate. Lower sampling rates deliver higher resolution readings. The maximum sampling throughput rate of the DI-2108 is 220 kHz, providing 12 bits of resolution. Rounding off the analog subsystem are anti-alias filters per channel with automatic selection of corner frequency at approximately one tenth of the sampling frequency. Finally, an external trigger input allows A-D conversion to be synchronized to external events.
The DI-2108 provides 7 digital ports, each configurable as an input or a switch. Input protection is provided to 25 V. When activated as inputs two ports allow dual functionality as discrete inputs, or programmed as a counter or rate input. The rate input features a 50 kHz maximum measurement allocated over twelve programmable measurement ranges (10 Hz to 50 kHz full scale.) The counter input provides 16-bit resolution and a terminal count value of 65,535. The discrete, counter, and rate inputs are members of the same internal scan list used by the analog input channels. This means that all enabled elements are acquired synchronously, which allows meaningful comparisons between analog and digital channels. For example, the rate input measuring engine speed allows rpm data to be acquired in lock-step with analog data. Configured as a switch a digital port can be used to control external loads up to 25 V @ 100 mA, and the switch can be controlled asynchronously without interfering with the scanning process.
A USB drive is used to record data in stand-alone mode. The DI-2108 can record continuously using a circular buffer with pre-defined trigger conditions or a record-until-full approach supporting remote start/stop. A push button allows manual start/stop control over the recording process. With a flash memory card incorporating SLC technology, throughput rates up to 160 kHz can be achieved. That rate drops to 50 kHz when using pSLC card, and 20 kHz using a flash memory card incorporating MLC. The included WinDaq data acquisition software makes configuring the DI-2108 for stand-alone operation quick and intuitive. Use WinDaq to set up channels and create a reference file. That reference file can then be copied to the USB drive and used for quick setup.
