My card reader works fine! I can still transfer files to and from the card!redhawk wrote:If you cannot flash a 4GB+ SD card don't blame the software it's usually non-compliant SDHC card readers that are the problem.
A simple solution would be to upgrade your SD card reader like the ones sold in Poundland.
Thanks, but I am using a USB adaptor, and not a built-in reader. I have used this on other computers, although just to transfer files, without a problem. Are you saying it is that type of reader that doesn't work? Or should mine work fine?Wheel_nut wrote:Cyborg4, You should take Redhawk's advice and try a different SD Card to USB adapter.
Many Laptops have SD Card slots which work when reading and writing using Windows Explorer but are NOT recognised by Win32DiskImager. I use MicroSD cards and find that a SD Card to USB adapter plugged into a USB socket works very reliably.
It does give me the device, but then it just gives me an error when I press 'Write'!Wheel_nut wrote:Yes, Win32DiskImager seems to be fussy about SD Card adapters. Some work and some don't.
In Win32DiskImager, after you select the source Image file using the Browse button, then click on the destination drive button at the RHS of the panel, it should give you a choice of any available drives to write to. If nothing shows up, try a different adapter and/or SD Card.
Hi CB4 - sorry to even have to suggest this, but is it possible that the sliding 'lock' switch on the card has somehow moved to the 'locked' position since you did your various operations on the card in Windows?cyborg4 wrote:Important information listed in bold.
I have waited four and a half months for my Pi, and then when it turns up I can't use it! I am using Win32 DiskImager and have just performed a scandisk on my SDHC card ( that I have plugged in through a USB SDHC adapter ) via the GUI. I now am unable to write to the card via Win32 DiskImager or dd for Windows, and yet I can still write files to the SDHC in Windows Explorer. I am using a Sony SDHC C4 4GB with the product number SF-4B4. ( The official Sony support page for this product is at http://www.sony.co.uk/support/en/product/sf-4b4 ). Can anyone help? I am using a Windows 7 32bit OS.
Good tool... however BE VERY CAREFUL when using it. Unlike Win32diskimager which defaults only to inserted removable drives, Roadkil defaults to Drive C which can make for a very bad day if you are not paying attention. It also references to drive letters and then Physical Drives which might confuse some.itsonlyme wrote:For those having problems.

Sorry about long time replying - getting a lot of spam users on my social network! Win7 32bit is the OS.Wheel_nut wrote:What Windows Version are you using?
XP+SP3? Vista+SP2? Windows 7? or Windows 8?
Is it 32Bit or 64Bit?
No, the lock switch definetely isn't on because I can format it. However, I just reformatted and ran Win32 DiskImager and it gives me an Error 3 : The system cannot find the path specified. I am pointing it to a .IMG on a network drive, could this be to do with it?SiriusHardware wrote: Hi CB4 - sorry to even have to suggest this, but is it possible that the sliding 'lock' switch on the card has somehow moved to the 'locked' position since you did your various operations on the card in Windows?
Working in Windows, try reformatting the card: With the card in the reader and the reader in the computer, use a file browser / navigator (such as Windows Explorer) to look at the drives on your system. Right-click on the icon for the drive/reader with the card in it, and select 'Format'. If offered the choice of 'Quick Format', reject that choice / uncheck that box so that Windows will fully reformat the card.
Alternatively, if you have access to a digital camera which can use SDHC cards, put the card in the camera and use the camera's 'format card' feature to format it - it will probably create some unwanted folders (such as 'DCIM') on the card, but don't worry about that - once Win32DiskImager is able to 'see' the card it will overwrite everything on it anyway.
Either way, see if win32 DiskImager is now able to write to the card. Incidentally: Win32DiskImager nearly always comes up with an error message about the media being 'in use' when first run. Just click OK to make that go away, and then carry on.
Windows has always been funny about network drives. I don't know why, but it doesn't treat it as a storage device, but as some strange proprietary device. Also, your network probably isn't fast enough to access a 2GB image file, unless you have CAT6 run around your house (very expensive ).cyborg4 wrote: WAHEY!
I've solved it! The problem was that I was directing Win32 DiskImager to a IMG on a mapped network share! The minute I switched the IMG file location to the main HDD on the PC, the problem was solved!!! Please anyone else using corporate networks to image the RPi, take note. This may solve your problem!
