Hi all- first post here.

I have a new 32GB flash drive- maker unknown (it was a freebie from Micro Center). It opens fine on my work computer, but it is not assigned a drive letter on my home machine (home machine runs Win 10 Home Premium 64-bit, work machine is Win7 Enterprise 64-bit). It appears in Device Mangler as "USB Mass Storage" or something to that effect, and under Devices and Printers it's listed as "USB Device". I have gone into Disk Management and attempted to assign it a letter, but I received (numerous times) the error message, "The operation failed to complete because the Disk Management Console view is not up to date." I tried refreshing the console to no effect. Numerous reboots didn't help. I uninstalled the USB drivers through Device Manager and nothing changed. I copied the .inf directory to a different subfolder, deleted the USB drivers, and pointed Windows at the new folder for drivers, but nothing changed. I looked into the home machine's BIOS but was not confident enough to do anything there. The flash drive is formatted for FAT-32. I just wiped it clean and can reformat it need be. Any and all suggestions are appreciated!

I would take the stick to the office and attach it to your computer there and try changing its drive letter using disk management or diskpart (in an elevated command prompt). I would change it to something that is far from the other drives like M or N so that there is no overlap with any drives on the home machine.

And if you have not already tried other ports, particularly on the back, I would.

Hi again. Unfortunately, formatting it for NTFS didn't solve the issue. The drive still appears in Disk Management, but I am still getting the "The operation failed to complete because the Disk Management Console view is not up to date" error.

Any suggestions, please? Why the heck does it work on one machine and not another? Seems like I might be able to fix it in BIOS but I am not knowledgeable enough to go in there and change stuff. Thanks.

Hi Shon12,

Thanks for your suggestion. Unfortunately, no joy. The flash drive didn't even appear to be listed when I listed the volumes. I have 3 available USB ports on the front of my machine (and before you ask, yes, I tried plugging the mystery flash drive into a read USB port). I put in 3 randomly chosen flash drives and started DISKPART and listed the volumes. That's the first screen shot. I then shut the machine down, removed the 1GB flash drive and replaced it with the 32GB flash drive. I started DISKPART again and listed the volumes. That's the second screen shot.

Am I just missing something here?

Thanks, good idea. Is this a weird thing or what?

Heh. Doesn't get much cheaper than this, I guess. It's more just bugging me than I really need the thing. Sorry for making it everyone else's problem too. A little :)
