X-Raid Expanding
ReadyNas Model: ReadyNas Duo V1
Firmware: 4.1.16 (latest firmware)
HCL HDD of 2Tb
Model has 2 Drives (0 and 1)
Raid Config: X-Raid
I used to have 2 Drives in X-Raid mode. 2Tb drive working fine. Suddenly there was a drive failure. Slot 1. I purchase a replacement drive. In the meantime i was working with 1 drive (Slot 0). As i purchase a new drive (same specs) and load it on the Slot 1 the unit is not visibile (when it was visible before) in ReadyNas Raidar SW. When i look into the front side of the unit power light is in. Light for Drive 1 (Slot 0) is on steady. Drive 2 (Slot 1) is off. When i remove the Drive 2 (Slot 1) the unit is visible in ReadyNas Raidar SW. At this point I check the logs of the system and im getting this message: The disk attached to channel 2 could not be used. The most common reasons are RAID resync in progress, faulty drives, and disks that are too small to be added to the array.
Disk is new and the same volume size.
Appreciate your comments on what could be the problem. I should be able to insert the disk and create a successful mirrow. Right now I only have a single disk working.

One possibility is that slot 1 in the chassis failed, and not the disk.
I suggest two next steps:
(a) power down the NAS, and shift the drive in slot 0 to slot 1 (leaving slot 0 empty). See if the NAS powers up.
(b) connect the new disk to a Windows PC (either with SATA or a USB adapter/dock), and test it with the vendor's tools - Seatools for Seagate; Lifeguard for Western Digital.
- I change the drive located on slot 0 to slot 1 and didn’t loaded. It power up but it was on the boot process. Never loaded fully.
I took that drive and placed the new purchase drive on the slot 1 (no hdd on slot 0) and into booted but is blinking all the lights on the front.

If that is correct, then unfortunately the problem is not repairable.
If you still have the original "failed" drive that you removed, you could see if the system boots with that drive in slot 0 (with slot 1 empty). If it does boot, then that would prove that the original failure was the chassis, not the disk.
You could also see if RAIDar is reporting a no-disks status with a disk in slot 1 (but not slot 0). https://kb.netgear.com/20684/ReadyNAS-Downloads
As far as the LEDs go, here's what they mean:
LED blink behavior for 2 disk systems is three quick blinks of all disk LEDs and the backup LED, followed by a 1s delay, followed by a number of slow blinks. The number of slow blinks will be the error code.
Current error codes:
1 - Vendor mismatch
2 - No disks detected
3 - Bad contents on root partition of disks
4 - Flash error
5 - Unsupported RAID configuration
