Raspberry Pi Imager Error Running Diskpart
Aureo Harvey
Normally, this would be the cause of "locked" SD cards, use the adapter that accompanied the SD card when you bought it, it has a lock switch on the side, insert the sd card, then slide the lock switch from LOCK to UNLOCK, then try the pluging your SD card again and see if it works.
I've reset the lock slider (locked and unlocked a couple of times), removed and re-connected my card reader on 2 different USB ports (not on a hub). I have full access to the card and have formatted, read and written to it after each change to confirm that's not an issue. I've tried a couple of images from and get the "Access denied error 5" each time. The only thing I've not been able to test is with a different memory card.
Ran into this, you are likely on Vista or Windows 7. The issue is that you need to run Win32 Disk Imager "As Administrator" when you starting it. Raw writing to a block device is an admin function so trying to run the program as a limited user will cause this error.
"Run as administrator" (which I am already) doesn't help with the Lock Error 5 on my Win 7. For writing the diskpart utility can be used to clean it and that releases whatever lock the OS has on it but I can find no way to read it without the Error 5. Help!
Hi, Don't know if you're still having this problem but I found that my music player (MusicBee, but I would assume others such as winamp and Foobar2000 will do the same) had locked my card as it wanted to sync music to it. I stopped it from trying and the image wrote fine.
Indeed a quick scan from google indicate that the API changed with Vista forward. Since we still build with MinGW API (XP and earlier), this is probably where our problem lies and will hopefully be resolved when we can update our build environment to a newer opensource API (mingw64?).
Thought I'd share I ran into the same issue tonight and had no luck working through the error. I run a program called 'Unlocker' which will tell me the programs that are keeping my files locked. It initially found some random software locking my SD card but even after I unlocked it 'Error 5' persisted.
In the end I moved my work from my desktop to laptop which is also running Win7 Home Premium 64 bit. The Image Writer software worked perfectly on my laptop. Oddly enough I just installed a new HDD in it about a month ago and I've been working through all the OS updates. So I just confirmed its fully up to date with all the pending updates and it didn't experience an issue.
I've had this problem. I now have about 5 SD cards that I use with my RPi, none allow me to read using win32 disk imager. I've tried running as administrator, even running in safe mode. Doesn't work. I then tried a new card, straight out of the packaging. This worked fine, no error 5. However, I then wrote Raspbian onto the SD and installed it in the Pi. Later, I then tried reading it again - and then I got Error 5 again....
Found a steady way to simulate/duplicate this problem on Windows 7 desktop.
I put a Windows 7/Embeded OS into a 4G or 8G CF card (I also tried CFast, the same;probably SD card will also be similar via SATA-SD converter)'s NTFS partitions(s).
Then if I use a USB2->SATA converter and then a SATA->CF converter, to read and write a gain, write is always failed half way. (Windows 7 detect the card as hard disk drive)
My theory is
1. I sense that MS Windows 7 is constantly meddling with NTFS hard disk drive, even if there is no explorer window/instance open.
2. much less meddling if it's NTFS partition on removable media (but not hard disk, as detected by OS)
3. maybe current way of identify card by drive letter list is a bad idea (must have a letter assigned, but once doing so, windows 7 start to fool around with the card's NTFS journals non-stop; but we totally can strip off the assigned letter by "Manage" tool from "My Computer" right click menu)
4. there was a WinXP tool before called "SelfImage", which uses disk ID and partition ID to identify the drive and partition, which means we totally can just take away assigned the drive letter, but shield off Windows from meddling with card, even via interfacing SATA converter tool in between (man! SATA Cfast converter HW are way much cheaper than USB Cfast reader!) . Can we have something similar to the "SelfImage" way?
Just some points missed out during my previous submit:
(Point 3. more:) Even if it's detected as hard disk (via SATA converter), if there is no letter assigned, Windows 7 seems to refrain from touching the NTFS partitions. Maybe an easy way to simulate is just to use a USB2->2.5" notebook SATA drive, but the content in the SATA drive has a windows 7 on it. Try to backup/read and restore/write on a different PC/desktop, using Win Imager32.
I formated the USB memory stick and the format application informed me that the USB stick was used by another application and if I wanted to continue. I confirmed to continue and once the formating was complete I tried again using the Disk imager and it worked. That is how it worked for me with Error 5!
The Process Explorer tool from www.sysinternals.com has an option under "Find / Find Handle or DLL".
Then enter the drive letter (in my case it was i:) and it will show all processes with your SD drive open.
In my case it was process recordingmanager.exe from Real Networks.
Kill the processes and the write will go smoothly.
There is one easy way around this.
1. Format the USB/Media device using the windows format tool in explorer.
2. Then copy the image to the media.
If any processes are using the partition the format tool will close them after prompting.
I had to use CMD and DISKPART to format the drive, after which I was able to write the image to the HDD. You just need to follow the CMD steps in this video =hmKKKfBYsmU Basically I made my external HDD bootable.
Possible solution, apologies if this is a repeat: I had the same Access Denied Error 5 message when trying to burn to a 16GB USB drive . When I gave up and tried to eject my USB, windows claimed it was in use by another program.
The first few sectors written to the the device are likely to contain the partition information. Apps, either OS or 3rd party, scanning for drives for whatever reason are able to read that as soon as it is written so they try to get an handle on the partition / device, effectively blocking the writing process.
Skip the first chunk of data (first 1024 sectors?) and write everything else. This will be meaningless data to the OS. Finally, after the write loop is done, go back and write the first chunk of data.
You just got off the computer store with an 8gigabyte Raspberry Pi. You pay no mind to the size because you have a spare 64gigabyte SD card at home. You install the card on the hardware and it has refused to boot. You were not prepared for this, were you? How do you get this SD card to work? What are the special requirements for Raspberry Pi SD cards?
This article will guide you as to why you need to format your SD card, The Raspberry Pi SD card format, Raspberry Pi SD card size and most interestingly, how to format or reformat an SD card for a Raspberry Pi. Let's dive in, shall we?
The Raspberry Pi is a group of small boarded computers that were made majorly for teaching basic computer science in learning institutions. They have been in existence since 2012 and have since then gained relevance in other fields such as research, robotics & Artificial Intelligence, and Climatology. The Raspberry Pi became very popular for its portability and because it is inexpensive.
Due to its peculiar nature, it also possesses some special features to make it work. The SD card used in the Raspberry Pi is one of them. These SD cards should be of special formats and sizes to prevent any irregularities in the performance of the machine. We'll look through these special features as we go on below.
Today, there are 3 major formats of SD cards. They are the FAT16, FAT32, and exFAT formats. Each format represents classes of SD cards based on specifications provided by the SD association. The FAT16 format is found in SD cards and their capacities are from 128Mb to 2Gb of data. The FAT32 on the other hand is found in SD High Capacity (SDHC) cards and can take information between 4Gb to 32Gb. The last format, exFAT, is found in SD Extended Capacity (SDXC) cards. These cards can take data ranging from 64Gb to 1Tb.
The Raspberry Pi's bootloader can only read from FAT16 and FAT32 SD cards. Thus, if you have any SD card with capacities higher than 32Gb, you have to format or reformat such SD card to FAT32 before installing on your Raspberry Pi. Now that you know the format, Let's talk about size.
The Raspberry Pi comes with an 8Gb SD card installed. It's great if you are not a constant user of the computer. If you are, then you'll be getting the "Low Disk Space" warning soon. This is why most Raspberry Pi users use SD cards with a higher capacity. Cards with capacities greater than 32Gb have been found to work fine, if properly formatted (As you'll learn in this article).
Before you go to the next step, it is important to keep a backup of important files and documents on the SD Card before formatting or reformatting the card. RecoverIt is a great tool for recovering lost files on a drive or SD Card.
Step 3. A warning message will pop up to seek confirmation for the formatting process. Click on "OK" if you're set and click "Cancel" if you have not backed up your key files and documents.
Step 2. Type "format /FS:FAT32 X:" into the command box and press enter. The card begins to be formatted and once completed in an hour or so, the SD Card is ready for use on the Raspberry Pi.
If you own a Mac OS system, you are not left out on getting yourself a reformatted SD Card. It is easily done using Mac's inbuilt tool known as "diskutil". Diskutil is similar to the diskpart tool on windows OS. To format your SD card for your Raspberry Pi, follow the steps below.
