App says "SD Card Unsupported" and "Read-Only SD Card."

[ Edited ]

When I try to wirelessly access my 64GB connect drive, using the App, I receive a red error message at the top that says "SD Card Unsupported". It gives me the option to touch a "refresh"-like icon. When I do, it says "Read-Only SD Card." It will not allow me to change any settings on the drive, nor can I view any of the contents. 

 

If I attempt to connect to the drive with my computer, the web browser simply says that it cannot connect to the page.

 

When drive is connected to my computer, I can read and write files perfectly fine, it mounts immediately, and storage information shows up in the Disk Management window in Windows. It acts just as normally as a flash drive would.

 

The wireless network does show up properly, both my computer and phone are able to connect to the wireless network. However, neither are able to read/write/access the drive.

 

The App also only shows the battery level. It won't show my phone's storage space nor will it show the space remaining on the drive.

 

Edit: It also just started doing something really weird. After being plugged into my computer for ~10 minutes, the light started flashing rapidly and would act as if it were being unplugged and plugged back into the computer for about 15 seconds. Then it stopped. After 10 more seconds, it started doing it again. 15 seconds later, it went back to normal and hasn't done anything since.

Try doing a hardware reset on the stick see if that helps. If not you can try reloading the FW. If you are still seeing similar issues try formatting the drive using a windows computer. Use the file system exFAT. If all that fails to resolve the issue it would probably need to be replaced. Contact sandisk support to check warranty status.

Had this exact same issue happen to me and I was about to give up, but finally had a breakthrough, so I made an account just to post this.

 

Format the Wireless Stick using the "HPUSBDisk" Tool:

 

http://filehippo.com/download_hp_usb_disk_storage_format_tool/

 

Just select your drive, select "Fat32" as the filesystem type, uncheck "quick format", and click "start"

 

Allow the format process to complete and you should be back in business.

 

I tried many other methods including all of those suggested both in the SanDisk KB and forums and this is the only thing that actually worked. 

 

It is worth mentioning that when this problem occured for me in the first place, it was following a format of the WirelessStick (16GB) on a Windows PC. Following that format I had the exact issue that the OP was/is having.

I've been busy for the past month with work and whatnot, but since you responded here I decided to try and mess with the drive some more. Since I have the 64GB version, I can't use Fat32, which is probably worth mentioning for other people trying this. 

 

I decided to format the flash drive with Windows' Disk Management once again, this time using exFat and it has just started working for me again. Wirelessly connecting on my phone now works as well as on my computer.

 

Unfortunately I can't exactly figure out what caused it to start working again. 

 

I set WhiteCoat's post as the solution, as that seems to be a great way to at least get started. Any formatting tool will probably work, but it just seems random as to whether or not the drive decides it wants to work.

 

I did use the HPUSBDisk tool that you linked, and it caused the format to fail and the drive wasn't recognized as a device with any kind of storage. That's when I decided to use Windows' disk management tool, formatting as exFat. The volume showed back up again, and I decided to try connecting to it on my phone... and it was working.
