I have a Sandisk Ultra 32 GB flash drive which won't show up in my computer. When I plug it into the USB port the computer makes a sound as normal to acknowledge that the device has been plugged in but it doesn't show up. What I think used to happen was that the computer made a sound, the light flashed for a few seconds and then the computer made a second sound and the drive showed up in my computer. The light on the drive is flashing on and off all the time. I went into control panel, administrative tools, computer management, storage, disk management but again the flash drive does not show up under removable drives. I then went into control panel, device management and opened up disc drives. When I do this my Sandisk Ultra USB device shows up. there is no red x or yellow exclamation mark beside it. So I right clicked on the drive and choose uninstall. The drive disappears. I then went to the top, right clicked and selected scan for hardware changes. The drive now reappears. If I right click and choose properties it states this device is working properly!
I have opened the device and removed the innards in order to check the four connections of the USB connector to the circuit board but there are no breaks and everything appears to be normal. If this was an empty flash drive I'd simply throw it in the bin however it isn't empty. My mother has Alzheimer's and is now in a home. When clearing out her house I came upon thousands of old photographs which I have been scanning and transferring onto this flash drive the idea being to be able to show her a slide show of old photos to stimulate her memory. Most of the photos I transferred over are now gone as I threw them out once they were on the drive. Does anyone have any ideas as to what I should try next? I'm assuming that everything is still on the memory chip and that the fault lies in the board somewhere. I'm considering buying another drive and attempting to transfer the memory chip from mine onto the new one. Anyone tried that before? Would I need the exact same make/size of drive or are the chips generic fitting onto any board? Any help would be much appreciated.
