Unable to find G-SPEED Studio XL in disk utility or any G-SPEED software [OS X]

G-SPEED Studio XL does not show up in any of the available software utilties or in disk utility on OS X.

Currently all lights turn blue except for the last unit.

Hello Bronson_schoen,

Based on what your describing it could be a hardware issue. All drive lights should turn blue it could be a bad LED on the chassis or possibly a hardware issue. I would suggest calling our support center so that we can properly troubleshoot the drive.
