In this case it is highly advised to replace the faulty disk as soon as possible to avoid any data loss. In some cases the rebuild of the RAID might not start automatically. If you encounter this you may set the new drive as a spare disk first. The rebuild will start immediately after this is done. If you have any further questions about QNAP products or solutions, contact customer service through the Service Portal. You should hot-swap the faulty disk without turning the NAS off. The new drive should have at least the same capacity as the failed drive.
Remove the faulty drive from the NAS. Install the new drive into the NAS. You will hear a beep for 1. The Status LED will alternate between flashing red and green. If this does not happen automatically, please keep reading below. When the rebuilding is completed, the Status LED will be in green and the volume status will change to Ready.

RAID group types. Refer to the table below for explanations on RAID types:.
However, this setup does not provide any redundancy protection. So, in the event that a disk is corrupted or otherwise damaged, all data on that disk will be lost.
A striping RAID group combines two or more disks into one large, logical disk. It offers the fastest disk access performance but no data redundancy protection in the event of disk failure or damage. The disk capacity is the sum of all disks. Disk striping is usually used to maximize disk capacity or to accelerate disk access speed. Please note that RAID 0 configuration is not recommended for storing sensitive data. Disk Mirroring protects your data by automatically mirroring the contents of one disk to the second disk in the mirrored pair.
It provides protection in the event of a single disk failure. The storage capacity is equal to the capacity of the smallest single disk, as the second disk drive is used to back up the first disk drive. RAID 1 configuration is suitable for storing sensitive data on a corporate or personal level.
RAID 5 configurations are ideal for organizations running databases and other transaction-based applications that require storage efficiency and data protection. A minimum of 3 hard disks are required to create a RAID 5 group. The total capacity of the RAID 5 group is equal to the size of the disk with the smallest capacity in the array times the number of hard disk — 1. It is recommended though not required that only hard drives of the same brand and capacity are used to establish the most efficient hard drive capacity.
In addition, if your system contains four disk drives, it is possible to use three drives to implement a RAID 5 data array with the fourth drive kept as a spare disk. In this configuration, the system will automatically use the spare disk to rebuild the array in the event of a physical disk failure. A RAID 5 configuration can survive one disk failure without losing any system functionality. When a disk fails in RAID 5, the disk volume will operate in the "degraded mode". There is no more data protection at this stage, and all the data will be lost if the unit suffers a second disk failure.
A failed disk should be immediately replaced. Users can choose to install a new disk after turning off the server or hot-swap the new disk while the server is running. The status of the disk volume will change to "rebuilding" after installing a new disk.If the md-raid records are damaged, an operating system cannot access a RAID volume any longer.
From the user's perspective it looks like data loss. There are cases when with a bit of troubleshooting you can access data. However, consider contacting QNAP support before trying manual troubleshooting because sometimes they can help you troubleshoot the case for free. We cannot say that QNAP support can fix any failure, but you should make an attempt, anyway it is free and spoils nothing.
At worst you leave with what you had before and can proceed with some other troubleshooting options. The best solution in this case is to take the device to a local repair shop to check the PSU. Most likely after a technician replaces the PSU, the device will work again.

He talked to a grandmaster, figured out that an AI machine would have to recognize 100,000 possible board positions at any time, and that it would have to have the raw computing chops to crunch all possible combinations of these 100,000 board positions over and over again. Once that required computing power was possible (thanks to Moore's Law), it was time to move on to the next challenge -- becoming a Jeopardy.
Now, with the victory of Watson, it's time to move on to the next challenge - becoming the world's best doctor. The really exciting feature of the Law of Accelerating Returns is that it implicity assumes that one exponential technology builds on top of the next exponential technology. Something like 3D printing is an example of one exponential technology building on top of another exponential technology.
In fact, 3D printing may turn out to be the ultimate exponential technology for the coming 12 months, so much so that WIRED's Chris Anderson is betting his reputation on it.

In short, we could say that you must select those tipsters that suit your circumstances. The yield is of course one of the most important statistics to look at from a tipster, but perhaps it is overrated, since that yield is calculated taking into account the original odds.
