Summary:<\/strong> At times, QNAP NAS enters into Missing Mode due to various reasons. In such a situation, you can\u2019t access data on your NAS expansion storage. In this post, we\u2019ll provide some effective methods to fix the issue and recover QNAP NAS from Missing Mode.<\/em><\/th>\n<\/tr>\n<\/tbody>\n<\/table>\n

QNAP is a manufacturer of storage solutions and networking appliances. It\u2019s known for providing high-quality Network Attached Storage (NAS). A NAS is a device that is not only used for file sharing, but also for data storage, virtualization, and other purposes.<\/p>\n

A NAS consists of one or more hard drives. However, you can also expand NAS storage space by connecting expansion enclosures to it. This makes QNAP NAS ideal for data backup, video surveillance storage, etc. Due to convenience of use and high storage capacity, QNAP NAS<\/a> has become popular among home users, small businesses, and corporates alike.<\/p>\n

Unfortunately, QNAP NAS is also prone to problems and issues. Sometimes, NAS enters into Missing Mode<\/strong>. This occurs due to accidental disconnect or expansion unit failure. When this happens, the Storage Manager displays an error icon in the Overview<\/strong> section (see Figure A), and the Disks<\/strong> section shows the expansion unit marked with a disconnection icon (see Figure B).\"QNAP<\/p>\n

Figure B:<\/em><\/strong> Disconnection icon showing missing expansion unit in the Disks<\/strong> section.<\/em><\/p>\n

While in Missing Mode, QNAP NAS blocks I\/O access to protect the data stored on disconnected expansion storage. Thus, you cannot access the data on the missing expansion unit.<\/p>\n
