jhnyswng Posted January 13, 2018 Share Posted January 13, 2018 Hello, I've recently made some changed to my server and now i'm not sure what I've done to create these errors. I started to get notifications on my cache drive so i replaced it a few weeks ago. Since then I've also swapped out a drive with errors. Now this is what i see.. any help would be appreciated...

jhnyswng Posted January 13, 2018 Author Share Posted January 13, 2018 i noticed in the smart log that my sandisk usb drive is being recognized.

JonathanM Posted January 13, 2018 Share Posted January 13, 2018 https://en.wikipedia.org/wiki/U3_(software) Some drives can be reset to just be mass storage, others can't. See if there is a utility available from Sandisk to remove the CD emulation. Link to comment
JonathanM Posted January 13, 2018 Share Posted January 13, 2018 This should be obvious, but make SURE you have a backup of the contents of the drive before you start messing around with it. Link to comment
jhnyswng Posted January 14, 2018 Author Share Posted January 14, 2018 That worked. I had to make the usb bootable again to run. No idea why this popped up tho. I've been running this usb flash drive for about 2.5 years without that error thanks for your help Link to comment
JonathanM Posted January 14, 2018 Share Posted January 14, 2018 5 minutes ago, jhnyswng said: That worked. Just to be clear for others that may come across this thread, what exactly did you end up doing that solved the issue? Also, please edit your first post and change the title to something more specific, with the word [Solved] so if people search for the issue it's obvious how to fix it. Link to comment
jhnyswng Posted January 14, 2018 Author Share Posted January 14, 2018 I did a search to remove the cd emulation for Sandisk and and found there is software preinstalled that needs to be removed. https://kb.sandisk.com/app/answers/detail/a_id/2550/~/removing%2Funinstalling-u3-launchpad-on-a-pc I used Download U3 Removal Tool . This gave me an option to save all contents of the drive. After that i had to run the make bootable program to enable the flash drive again. Link to comment
