Since I updated the new version, when I go look to do a custom scan on my usb drive. That option isn't there anymore. Only window os and my laptop brand lenovo (D:)

Hello and :
 
By "USB drive", I assume you are referring to a USB External Hard Drive that might be "permanently" mounted (as opposed to a USB thumb drive)?
 
If so, it might be a Windows hiccup.
Another user recently reported something similar here:  https://forums.malwarebytes.org/index.php?/topic/170101-unable-to-scan-all-drivesdrives-invisibledisappeared/

A clean MBAM reinstall solved the problem for that user. So, let's start here:

• Please follow the steps in this pinned topic to uninstall your current version of MBAM and reinstall the latest build - MBAM Clean Removal Process 2x
• If that does not correct the issue, then please read the following and attach to your next reply the 3 requested logs - Diagnostic Logs (the 3 logs are: FRST.txt, Addition.txt and CheckResults.txt)
• NOTE: More info about v2.1.8 HERE; User Guide ONLINE; User Guide PDF; FAQ: Common Questions, Issues, and their Solutions

Please let us know how it goes.

Thanks,
