I have a USB flash drive which is no longer recognized by my computer. Windows Disk Management and DiskPart report No Media with no storage space (0 bytes) on the drive and I cannot partition or format the drive:     If the drive appears in Windows Explorer, trying to access it returns an error message indicating that there is no disk inserted, such as the following:     Please insert a disk into drive X:.   Various disk partitioning and data recovery utilities don't recognize the drive or only give a generic name for the drive and cannot access the contents of the drive.  What can I do? How do I recover data from the drive?     This question comes up often and the answers are usually the same. This post is meant to provide a definitive, canonical answer for this problem. Feel free to edit the answer to add additional details.

I have a bootable CD image that I would like to transfer to a USB stick, so that I can boot from it. The Startup-Disk creator doesn't support it. How can I make a bootable USB disk from it? The ISO is quite old so that might be a problem.

I want to connect 3 Windows computers (2 Windows XP, 1 Windows Server 2003) to an external USB hard drive via USB.  I would like each computer to be able to directly read and write to the HD as if it were directly connected to each computer.    Using special file transfer software isn't a viable solution.  Sharing the HD over the network also won't work for me.  Is this possible?  Thanks for any advice!

How do I remove a USB drive using the Win32 API? I do a lot of work on embedded systems and on one of these I have to copy my programs on a USB stick and insert it into the target hardware.  Since I mostly work on the console I don't like to use the mouse and click on the small task-bar icon hundred times a day.   I'd love to write a little program to do exactly that so I can put it into my makefiles, but I haven't found any API call that does the same thing.  Any ideas?

Recently something went wrong with my external WD passport. It is not accesible anymore in Win 7 and the type is now currently RAW. I recovered all the data so formatting it is no issue.  I tried formatting it with windows but it seems to be unable to do so. Does anyone have any suggestions how I am able to get this RAW drive back to NTFS or FAT or whatever.. as long as it works.  Thank you in advance

After considerable review of the options, I tried and failed to create a usable live Ubuntu USB with persistent storage using what seemed like "best practice" instructions at  I suspect I'm one step away from a full solution, but I need help.  I reviewed answers on AskUbuntu and other places before starting, including many responses by @C.S.Cameron and @sudodus. Answers for OS versions earlier than 18.04 are now of uncertain value for running 18.04 or later due to various issues. Hence I opted to follow the comprehensive and recent instructions at the URL above.   After following the instructions, I seem to have a USB drive formatted by mkusb as predicted. When I attempt to boot, the BIOS/UEFI process identifies the USB stick as a possible boot location, but when I select it for booting and proceed, I am returned to the same screen for choosing a boot location. For some reason, the USB stick is rejected as a viable boot option. I have tried the process 3-4 times using 2 iso images (18.04LTS and 19.10) and 2 USB sticks (Sandisk Extreme 64GB and Sandisk Cruzer Facet 16GB). Below are links to two screenshots of GParted analysis of the resulting USB sticks.

If a computer case has a USB port in the front, will it support USB 3.0 if my motherboard supports it? Or does the case vendor need to specifically mention USB 3 support? (BTW, I haven't seen such case yet.)

I'd like to create a Windows bootable USB stick, but I don't have a Windows machine with me at the moment to do so. How could I achieve the same using Ubuntu?

Recently, I bought an USB flash drive which has a cool design.  The seller said it is 256GB however, I've already known that capacity would be fake. Anyway, I bought it cause of its cool design and want to use this USB flash drive anyway.  What should I do?  I've tried to find a proper tool(vid 1908 / pid 1320) but couldn't. Can I repair this through Low level format? Or partitioning this through Linux?

I have a Windows 8 PC and my Nikon D3100 isn't showing up on it. It says USB device not recognized. I have updated the USB drivers, but no joy. Sadly, i don't have the disc that came with it.

In my laptop (a Lenovo y470 ) there are three USB ports. One of those is USB 3.0 others are USB 2.0 . I do not know which one is what. When I copy data from my External HDD it transfers at 38MB/s from all of the USB ports. (Which is a good speed for USB 2 transfers, but to low for USB 3).  I used the device manager to confirm that I have one USB 3.0 port.    Is there a way a can figure out which port is 3.0 ?

I want to use my flashdrive in Windows XP, which I am currently running in Virtualbox, but when I open up the settings to enable usb usage, I get an error: Failed to access the USB subsystem. VirtualBox is not currently allowed to access USB devices.  You can change this by adding your user to the 'vboxusers' group.

My  is not recognized by windows. When I connect it to the computer I do not see "Mass Storage Device" Under "Universal Serial Bus Controller". I already check the troubleshoot and test for everything (Cable is OK, I checked in another computer, etc)  It happen after I connect the Hard Drive to another computer which then I realized it's USB Port was corrupted and problematic.  Is there a way I can fix this Hard Drive? Or any utility which can access this hard disk? When I connect Hard Disk, it turned On (The Light become green) and it start vibrating.  P.S: I check my drive again SeaTools, but  cannot recognize it too.

When I create a bootable USB stick (Ubuntu) on Windows, does it mean that the changes that I will do (let's say save a new file called "abc.txt" on the Ubuntu desktop) will those changes be reflected the next time I boot this USB on some other computer (I will see the file "abc.txt" on the Ubuntu desktop)?  Next one might be a pretty stupid question but here it is:  Will it use the computer's RAM or use the space left on the USB as RAM.  Thanks

3 years ago I went volunteering and brought back this weird USB cable and in those 3 years i never could figure out how to use this USB cable and what is the purpose of its disposition. So... what do you use this cable for (I think those are 3 USB 2.0 connectors - I don't know how to differenciate USB 2.0 and older USB's...) ?

My USB drive used to be originally 8GB when I bought it.  I'm trying to reformatted in Windows 7 by right clicking on the drive and selecting Format.... But the capacity only shows 250MB.  Is there something I can do to get the original size back? Maybe it got partitioned in a weird way?   The  flash drive is a SanDisk Cruzer Micro 8GB. I got it from Wal-Mart but this is the same drive.
