Quality Network Attached Storage (QNAP) are NAS boxes that are used as a backup hub or storage unit systems that store important files and media such as photos, videos and music. They consist of one or more hard drives that are constantly connected to the internet. The QNAP is like an external hard drive, but rather taking it everywhere, it stays at home and is accessible to use at anytime and anywhere.

Data recovery to retrieve the data back up on the QNAP is necessary when the data is critical. The key is to regular monitor the health of the drives in order to avoid a disaster. In most cases, the RAID system of the QNAP collapses because of a failure of one or more of the drives.

Let’s take the example of a QNAP NAS with one of the four drives that has failed. The drives used in the NAS box are 2TB WD red SATA / 64MBWD20EFRX – 68EUZNo NASware 3.0. The failure of one of the drives has caused the RAID to collapsed. Messing up with the drives could cause more harm than good. The best way to deal with this type of situation is to extract the drives from the box and rebuild the RAID virtually without the NAS box. The best tool to use to do this successfully is PC 3000.

You can insert the RAID configuration parameters manually into PC 3000, rebuild the drive image of the RAID from defective to healthy which allows you to create a virtual RAID. Once the RAID is rebuilt, you can access the data.

The work may take days. A word of caution: once the data has been recovered, in order to take any risk, the drives on the QNAP need to be replaced, as they can no longer be trusted. The replacement drives are then inserted in the box, data is transferred if necessary and the QNAP is fully working.
