There are a couple of reasons why this may occur.
1. Low power from USB system ports:
=> If using a workstation, try using the ports at the back of the system
=> Connect to a USB 3.0 port if possible
=> Use a powered hub to connect to the USB port
2. Security Software is interfering with drive communication (This occurs often with McAfee anti-virus software):
=> White list (exclude the drive in the security software console.
You can white list ironkey.exe and if your software allows for wildcards, use *.ironkey.com
If additional processes need to be white listed, access the following link for more information;
