00:00:33.217753 Console: VM runtime error: fatal=false, errorID=BLKCACHE_IOERR message="The I/O cache encountered an error while updating data in medium "ahci-0-0" (rc=VERR_ACCESS_DENIED). Make sure there is enough free space on the disk and that the disk is working properly. Operation can be resumed afterwards"
Basically, it got an I/O error on what I guess is the USB drive. Possibly the USB drive is FAT formatted. And/or your user does not have permission for sector level access to that drive.
I hope you weren't trying to access the USB drive as a raw drive and a USB drive at the same time. That would either be blocked by the host OS, or it would corrupt the drive. Happily this seems unlikely, as the VM has only enabled USB 1.1 level support.
