What should I do if the hard drive is damaged when creating a RAID1 with a D2-310/D4-310/D5-300/D5-300C/F4-300 model?
No data will be lost if one hard drive is damaged in RAID1 mode; however, you should fix the array as soon as possible.
The steps for data recovery are as follows:
1. The device should be powered-on and connected to your computer throughout replacement of the faulty hard drive. The capacity of the new hard drive must be greater than or equal to the capacity of the faulty one.
2. After replacement of the faulty hard drive, data will be automatically restored. The time required for data recovery is related to hard drive capacity, ranging from several hours to dozens of hours. During data recovery, both the device and your computer must remain turned on, however.
3. During data recovery, the indicator on the new hard drive will flash orange.
4. When all hard drive indicators remain fully and steadily lit, data recovery is complete.
