DW Spectrum User Manual
Occurs if the Server is unable to write data onto one or more storage device. This is a default event.
Storage issue may be caused by any of the following:
•Hard disk malfunction.
•Insufficient rights – The permission to write on disk or recorded folder may be restricted by the computer Administrator.
•Hard disk is too slow – Too many cameras are attempting to record simultaneously and the hard disk cannot respond quickly enough. It may be useful to add another hard disk drive.
•Disk is full – There is a required reserved space of approximately 10-30GB for local storage or 50-100GB for NAS devices. When available disk space reaches that threshold, the oldest data will be overwritten by new data. If available storage drops below this threshold, the server will write data to the disk but instantly erase it.
•System Drive is Full – Occurs when the partition on which the operating system is installed has less than the required amount of free space (5GB for PCs or 1GB for ARM devices). It is highly recommended that space be made available as soon as possible to avoid loss of data and system instability.
