![]() There is a high possibility that you could lose the integrity of the raid and therefore all of the data. If the synchronization fails because of a bad read from the other drives then you should immediately shut down and contact a Seagate NAS recovery company. ![]() There is however a caveat to this procedure. Even if power is lost during this process you can start over or continue where you left off. It is assumed you have already swapped the bad drive from the Mirror or RAID 5 and the Seagate NAS recovery process has been started. Out of the four conditions I mention this is probably the most benign. Status LED Blinking Red/Single Drive LED Alternating Red and Whiteįor this particular condition there is a drive that is currently being synchronized.At least you will have some recourse if something goes wrong. If you wish to try a rebuild then take the good drives out of the array and make sector level images of them in case the rebuild fails, or corrupts the data. With this being said, I can confidently tell you that from my many years of experience this particular function is what causes an approximate 40 percent failure rate and a call to DTI Data. Once completed simply follow the instructions that show you how to rebuild your RAID 5. In the case of a RAID 5 you have the same alternatives which is to pull the offending drive and replace it with a working drive. In either case you should take the good drive and make a sector by sector image of it in case one of the other options goes wrong. Alternatively, you could pull the good drive, mount it outside in a USB caddy and pull the data off using data recovery software. If it is one side of the mirror then there are two options, you can pull the bad drive, put in a new drive and follow the Seagate NAS recovery instructions to synchronize the mirror. For the NAS 2-Bay this could mean one side of a mirror is out, and in a NAS 4-Bay a drive from a RAID 5 is out. In this case the RAID is degraded and although functioning, has a drive out of the array. Status LED Blinking Red/Drive LED Solid or blinking White.If something does happen at least you will have saved the original state of the data and allow for a qualified Seagate NAS recovery company to attempt a full recovery. If the data on the system is critical then I would pull each drive and make a sector by sector image onto another system before proceeding. A full reset can in fact wipe out all data in order to give the device a clean start. If the operating system is being updated there is a possibility that the system will not boot at all and a full reset will be necessary in order to boot the device. There may be a file system check initiated that could in fact destroy data. If during the time of this status you lose power without the advent of a viable UPS the resulting power on could be catastrophic. All of these things mean that there are read and write operations in progress that will definitely affect the health of your NAS. This situation indicates that either the native OS (NAS OS 4) is being updated, there is a drive synchronization in progress, or there is a volume check in progress. Status LED Alternate Red and White/Drive LED Alternate Red and White.I offer the following as a guide to what to do if and when you have blinking warning LEDs from a Seagate NAS. Each drive has its own LED and the device itself has a ‘STATUS’ LED for identifying the current state of the NAS. In order to alleviate some of the guess work and stress when encountering a problem the Seagate NAS has a set of LEDs that offer instruction on the current problem. That being said there will still be occasions where the device fails and diagnosing the problem in a failure can in and of itself be a daunting task. Purchasing all of the hardware from Seagate does offer a certain seamless feel to the mechanism especially since the drives that are installed in the system are designed specifically for their NAS device.Įach NAS device is tested individually to ensure quality control and a long lasting device. A standard 10 GB Seagate NAS 2-Bay device is in the neighborhood of $700.00. The NAS can be purchased as a shell for a little under $200.00 and the user may add their own drives. The NAS is outfitted with a Marvell 1.2 GHz processor and a minimal 512 MB of DDR3 memory. The Seagate NAS 2/4-bay solutions are the bed rock answer for those who have a need for secure remote data access but want to remain conscientious in the area of cost. Seagate Technologies offers a low end NAS solution for the power home user and small business owner who has fewer than 25 employees.
