I have a sandisk ultra usb flash drive (SDCZ45-032G) that works perfectly on windows xp and windows 7 computers but doesn’t work on any windows 8.1 computers.
When plugged into a windows 8 computer, it just flashes. and in “my computer” it shows up but it doesn’t show the size…etc and I’m unable to open it without getting an error.
I’ve tried reassigning a new drive letter and trying the steps in this link:
I remembered that i bought 2 of these exact same pen drives, so i just tried the other one and it giving me the exact same problems so we know its not a faulty pen drive.
Its strange because the other one works perfectly on a windows xp and widows 7 computer as well.
i have the same drive and it works on my toshiba laptop, my Surface Pro, and my custom build desktop all running 8.1 so I don’t think this is a Win 8 compatiblity issue.
I went out and bought a 32gb lexar jumpdrive today and it works perfectly on all the computers and all the ports on the windows 8.1 computer.
I would put it down to the sandisk drive just being faulty but that wouldn’t explain why it works on every other computer i plug it in to and why my other other sandisk drive (same model) has the same problem.
Yes, this is definately a Microsoft incompatibility issue. I too have an almost new Sandisk Cruzer Blade 8GB stick that works on ALL machines except Windows 8.1
Another issue that MS seems to want to pretend doesn’t exist.
I have the same issue with my new SanDisk Ultra 32GB USB 3.0.
This machine boots both Windows 7 and Windows 8.1, the drive reads fine in Windows 7, reboot into 8.1 and it sows up in Device Manager as “Unknown USB Device (Invalid Device Descriptor)” and reports an error code 43 to the same effect.
