Replacing 2tb with 6tb

My Cloud OS 3 Personal & Network Attached Storage My Cloud

Hi

I am planning to upgrade the 2x2tb wd red with one of the drives as 6tb .

I am not sure if removing the drive will fail as its not in RAID. Its in JBOD only. How can transfer the 2tb content and replace the 6tb in wd nas without touching the other 2tb

So i should be able to copy the 2tb to 6tb once it is live. Can connecting the hdd to pc will allow me to read . if the encryption and raid is JBOD will it be mountable on windows platform.

What My Cloud model do you have? The single bay My Cloud units, the general subject of this subforum, do not have multiple drives within the enclosure.

For the single bay My Cloud models it is possible to upgrade to a larger hard drive but it involves running an “unbrick” procedure on the new drive to properly format it and add the proper firmware to the drive. If one has a single bay My Cloud model they can use the forum search feature, magnifying glass icon upper right, to find numerous past discussions on how to unbrick either a first gen v4.x single bay My Cloud or a second gen v2.x single bay My Cloud. The multi bay models generally have different methods/procedures when changing out the internal had drive.

I have WD ex2 ultra . its a 2 bay system nas. Currently the RAID so call JBOD ie no Raid 0 or 1 . Each disc is independant.

Now i want to put a 6tb on one of the slot bay. As 1st HDD started slowing down and only getting 40MB/s even though the space is 50% free and files were huge enought say 2-10gb files .

2nd HDD is getting rated 100MB/s + easily.

I am connecting via gigbyte line.

So planning to replace the 1st and put the 6tb .

My concern here is i need to move the 1tb of 2tb possible failure hdd so that i can keep 6tb running .

How can i copy the JBOD drive as they are formatted in ex4 partion. Can it be mounted in Windows without formatting.

I believe only RAID 0 or 1 is not possible to read.

If you haven’t already you should read through and post to the dedicated EX2 series subforum where people more familiar with that unit (and RAID) may be able to assist.

https://community.wd.com/c/network-attached-storage/wd-my-cloud-ex2

Further one may have to configure the drive/RAID through the My Cloud EX2 Ultra interface (Dashboard I assume). See the User Manual for the EX2 Ultra for more information on how to setup a new drive on that unit.

I’ll answer your question here @DirtyMacho.

and the answer is “be very careful”.

What I would suggest is that you do a backup of your data before you do anything. If you don’t have anywhere to backup your data, hence the reason that you bought a 6TB and wishing to upgrade without using Raid 1 (mirror), I still would suggest you find/borrow/purchase and return another set of hard drives, like from Costco, to backup your data before playing around with removing this drive and inserting that drive.

“Theoretically” you can remove JBOD and insert JBOD as you like and again “Theoretically” once one of the JBOD is removed you can insert your 6TB into that bay and make it another JBOD and just copy from one bay with JBOD to the other.

When I was testing the EX2 I was adding and pulling JBOD disks in a whimsical fashion and found that “for most cases” you can treat your EX2 as a dock reader with swappable JBOD disks; except you had to unscrew and re-screw those pesky guide posts. However that doesn’t mean that it is a guarantee that it would work for you.

The second answer to “whether a JBOD is readable on a dock” is No. Anything that is inserted into the EX2 whether it is raid 1 mirror or JBOD is unreadable outside the unit.

Alternatively you can pick up a diskless EX2 Ultra and use that to create a 6TB JBOD to copy over your other EX2 JBOD disks. Once that is done, you can remove one 2TB disk and insert your 6TB. The EX2 will ask if you want to integrate your new 6TB roaming disk into your current EX2, say yes. Then return your new EX2 diskless to whomever you bought it from :stuck_out_tongue: or maybe keep it for your now 2TB disk that is now being unused.

Optionally, transfer all your data over to your 6TB JBOD and with your pair of 2x2TB create a raid 1 (mirror) ex2 and use that for your more important data.

i got your point . But problem is disk one is slowing down even with 50% space left . i only get 30-40 mb but disk 2 is instant 100+mb/s

so i want to rma the disk 1 . Also the 6tb is not wd red its wd purple. But it is more reliable and robust like nas.

i will be mostly reading and writting videos . But not sure if wd purple cant handle docs or exe’s

I have close to tb’s of video’s which is consuming the 2.5tb of 4tb total 2 disk.

Why is that JBOD cant be read outside. Its not in RAID 0 or 1 for parity to be used . Jbod is independant.

I think it is a WD protection thing or perhaps a header with info indicating the type of disk.

if both disk 1 and disk 2 are identical in type and size, It is possible that because you have movies, photos on the second disk, it is the scans that is slowing your device down. Just guessing. If that is the case, your second disk full of movies will slow down no matter what disk you put in. Try turning Cloud access off, hibernate and re-power up the drive to see if there is a difference.

Well, yes and no. Although I’ve always said that the colours are simply what WD choose to stick labels on depending on the supply and demand, from this huge warehouse full of disk, but I’ve read that purple is slower on the read and better for sustained writing hence video feed writing. In other words slower on the random seek and better on continuous track to track writing. All this is hearsay or rather internet say.

You can confirm this for us afterwards :slight_smile:

of course it can as everything is just bits and bytes.

Good luck… and be sure to let us know how successful/failure you are after all is said and done.

ok how can i make a back to this 6tb in windows share and restore back the files
