I'm working on a device that writes some information directly to a flash drive, without using any file system (it just writes blocks of data directly to the disk sectors). After the flash drive is filled, I need to plug it into any computer with windows and read data using my application.
Everything works great except for when I plug the flash drive in windows warns me that flash drive is invalid an offers me to format it. I want to get rid of this message for my flash drives on any computer that have installed my windows application.
My flash drive have signature bytes at the start so I can always make out whether it's my flash drive or just a regular flash drive.
My idea is that I should be able to write some sort of service or driver which will check all flash drives and will disallow OS to mount my drives. However I don't know whether its really possible and I can't find any documents mentioning this sort of functionality.
I'd appreciate any docs / links / functions names that can help me suppress unformatted disk warning.
Make a tiny real partition at the start and format it to keep windows happy.
Then just use the rest of the drive as you please
This seems to work:
Remove the drive letter assigned to the device:
Right-click the 'Computer' (or 'My Computer') icon on your desktop or in the Start Menu and select Manage. The 'Computer Management' window should appear.
From the list on the left, select 'Disk Management' (within the Storage sub-tree).
Right-click the encrypted partition/device and select Change Drive Letter and Paths.
Click Remove.
If Windows prompts you to confirm the action, click OK.

I am writing C++ code for listing USB HID devices that uses HidD_GetProductString(). One particular device, despite the function's success, returns an empty string.
The classic Device Manager and gwmi in PowerShell both list the device using a generic name. However, Windows 10 Immersive Control Panel's Bluetooth and other devices window lists this device with its actual full name, which does not seem to appear anywhere. I did not find it in the registry either. I want to get access to this information.
Does anyone know where this app gets its information from?
My suspicion is that it gets it directly from the System process, which is also a holder of an open file handle to a device file, and perhaps it is the reason why the function returns an empty output. If so, how could I do it? Any suggestion is appreciated...
I've been using this phone a while, and I have been through tough times with it. Two bootloops, Google Play Services crashing infinitely, weird errors, everything. I'd say I've "bonded" with this Samsung and would like to take it up a notch.
I've been looking everywhere for ROMS for this phone and I haven't been able to find any, not figure out how. Maybe I'm just stupid but man it's aggregating.
I have a PC, Samsung driver's, Odin, and of course, my Samsung. I have everything I believe is necessary to flash a custom ROM.

At the minimum, I'd like it to have a theme changer.

What causes a _disk_id.pod file to appear on a windows flash drive, and is it advisable to remove it?
_disk_id.pod is created by Windows Live Movie Maker. I had accidentally changed my "choose default program ..." settings which was causing the video files to open with the Windows Live Movie Maker program. Even if you do not do anything with the video in the Movie Maker program or save anything in it the program will still create this file on the sd card.

For me I think the answer is _disk_id.pod belongs to media player software (in my case KMV).
I think it permits the software to identify a particular volume (in case you have saved playlists). The name kinda makes sense.
I have seen other explanations of .POD but none that make as much sense in this context (i.e. removable media).
I am attempting to make our webpage open when someone plugs in our USB device.
My Problem: When we plug in the USB device the autorun dialog appears but there is never an option to open/run the webpage we have specified. See below pic of the dialog we see. Isn't there meant to be an option that says something like "Open in Internet Explorer" or etc.?
What we are hoping to achieve is to have another option below 'Use this drive for backup' that says something like 'Open in Web Browser' or something that will ultimately open our webpage when the users decides to.
Heres our code that is inside the file autorun.inf which is placed on the USB device:
[autorun]
shellexecute=http://exds-test.epicservices.com.au/V10InstallationInfo.aspx
action=Open Website
label=EXDS USB Drive
According to this link, this will not work on modern OS versions

You've got to use a "helper" application.
I'm creating a FAT32 formatted USB Stick/Drive to ship a product. We'd like it to behave a bit more like the hybrid CD/DVD's that we create:
Insert the disk on Mac 10.6 or later and the drive opens up and shows you a window with the application in it. We can do it from a DMG or CD but the USB drive doesn't seem to want to honor the bless command.
On Windows, we've set up an autorun.inf. On XP it's not showing the icon, label, or opening the specified file. I know that you can't have Windows Vista and Windows 7 automatically open something or add an entry to the AutoPlay list by default, but it still should show the Volume Label and icon.
Here is my autorun.inf:
[AutoRun]
Action="Install My Cool App"
Open="InstallThis.exe"
icon="Ultimate.ico"
[Content]
MusicFiles=false
PictureFiles=false
VideoFiles=false
Are these things too much to ask for a USB stick? Anyone else out there shipping things on a USB flash drive and have overcome these issues?
As of Windows 7, AutoRun feature is not supported on USB drives. Only the following commands are supported:
label
icon
See Improvements to AutoPlay on Engineering Windows 7 blog.
Examples in Autorun.inf Entries do not use quotes for values. Does it work without the quotes?
MacOS might have implemented a similar approach to Windows 7: do not autorun anything from a flash drive automatically to protect you from malware.
