Greetings,
Copying 1.58 TB from an external HDD to WD My Cloud attached storage (a brand new SEAGATE 5TB) with a shocking speed 200Kb/s.
Time remaining: 165 days!
Better luck new, potential customers/buyers.
Has it maybe occurred to you that you might be doing something incorrectly? If you are trying to copy from My Cloud to 5TB drive using USB between the two devices, that is NOT how it is done.
Connect the 5 TB drive to your computer that is connected to your network and go through the Ethernet cables that connect the drive and the My Cloud to your network. It will help A LOT that your network speeds are gigabit.
Thank you for your response.
To precise, I have been trying to transfer/copy of 1.5 TB of data located on a computer attached external drive to a My Cloud Mirror attached USB drive.
I have already passed sewer also weeks with WD support stuff, all in vain.
There is is a serious, no resolved problem with attached USB drives with make My Cloud Mirror completely useless as cloud solution.
My Cloud Mirror is completely unreliable as far as cloud access is concerned.
Having attached two or even one USB drive already containing data make MCloud nonaccessible via web page. Only local home network can see it.
Simply a very unfortunate product on every level alas.
So, why don’t you attach the USB drive on the MCM, connect to PC also, and send the data from other drive to it? That is the way I would do it, even on my super fast DL2100. An attached USB drive on a MCM is slow; slower than on a PC. The MCM is not a PC. You are probably taxing the MCM CPU.
Just because you can’t do it the way you are doing does not mean the MCM is not any good.
That is what I have been doing.
The USB 5TB is attached to MCM and the source one ext HDD connected to PC.
As far as quality is concerned:
Do you know a single MCM user that is able to make the drive work with two USB attached storage containing data to it?
Thank you for you suggestions.
Sorry. I cannot answer your last question.
BTW, have you downloaded the complete user manual from www.support.wdc.com?
Nobody can.
Yes I have. Not only downloaded but also consulted 
While external USB drives are connected to MCM it becomes inaccessible from web page, my cloud app (iPad), no connection via SSH (SHH?). The drive (MCM) behaves as a simple external drive attached to a local network with USB attached extension.
Thank you mije27oct for your effort. I appreciate it.
As I mentioned I have passed several weeks with support stuff - no solution at all.
That is why I can state that the product is not fully functional and not reliable at all.
OK, good luck to you.
My Gen1 MCM quite happily works with a pair of 5TB elements desktop drives hung off it.
The first was populated from the MCM disks via SSH and using rsync at the command line. The second was populated as a back-up/mirror of the first, again via SSH and rsync.
From my experience of doing this kind of thing, that is the best way to do bulk transfer between either MCM<>USB drives or between USB drives both connected to the MCM. If you try and use any external PC on your network, then the transfer is going via that across your network which will slow things down.
The rsync command line method works, although it can take a few attempts to get everything sync’d if you’re doing a lot and it does take some time. I moved about 4TB between the two USB drives on my last sync, and it was done over a couple of nights and worked fine.
Thanks.
The problem is when I connect two USB drives (already with data) to MCM I lose any possibility to connect to it. No one could solve the problem.
There is no way to get access to it via SSH. The only way to operate it is to Windows explorer on my Home Network (LAN).
Still copying… 11 days remaining… (speed varies from 45 KB to 4.6 MB/s)
How big/small are the files you are trying to copy? That is a huge speed range that makes me wonder… I’ve seen speeds on the lower end of that scale when copying a large number of very small files to a regular external drive via USB.
There a huge variety of file sizes most of them are images.
Now I have got a 74 Kb/s (0.1 items/sec- using FreeFile Sync)… 133, 335 kb/s… 510… speed.
What services and indexing do you have enabled on your MCM?
It sounds like it’s doing a database scan or something on all the images etc and that’s killing the processor. On mine I have all that kind of stuff (remote access, DLNA etc) switched off unless I specifically need it (basically all mine runs is SMB, NFS and WebDAV) and it works fine.
As a test can you shut off basically every service on the MCM and then plug in your drives and see if you keep access or not to the system via SSH (or indeed just by web access to the dashboard).
Also do you have any of the add-ons installed? I know when I tried the anti-virus one for example every time it tried to run it the thing absolutely crucified my system and almost stopped it dead and became almost totally unresponsive. That one very quickly got removed again, much as I hated to do so for security reasons (although I guess you could argue that a system that’s too bogged down to actually connect to is the most secure of all, at least short of switching it off).
If you want to quickly copy files from an External USB HDD to the WD MyCloud
Connect the External USB HDD to your PC and Connect the WD MyCloud to your PC via an Ethernet Cable
(i did this when i 1st got the MyCloud and copied about 1TB pretty quickly)
Thank you very much.
As far as I remember I have no services enabled (except, I think FTP…not certain, but I took care of not enabling any useless in my case ones). No add-ons.
I will double check it just in case.
To do this I have to cut off power to reboot the drive cause I have no other control on it.
I will post here the results you can take your kind look in it DarrenHill.
Many thanks.
Update:
Here is my MCM Setting section:
Finally I have managed to (after forced rebooting, detaching and reattaching USB drives) to get access to the MCM via SSH. I am about to copy files using WinSCP.
The speed is not terrible - between 2.6 - 9.6 Mb/s.
In the same time I have checked a setting with my other MCM (also 2 USB attached HDD). As mentioned several minutes after connecting both USB drives the MCM has stopped being accessible on web or SSH. Both HDDs contained data before connecting them to MCM several months ago.
I have noticed that the empty drives attached and filled with data through MCM do not produce such sad effect. Only in case of attaching already filled USB storage the problem occurs. Perhaps there are a lot of exceptions…
Thanks.
But I am about to copy files from (1) PC attached external HDD to (2) MCM attached USB one.
I can copy the files from 1 to 2 drive via PC (attaching both to it). But in that case if I connect the second USB drive with a lot of data on it to MCM drive I will certainly lose contact with MCM as usual.
I have found that MCM keeps its connectivity (SSH and via web page) while two USB drives attached ONLY when I connect an empty drive and load it with data via MCM. If the USB drive included data (some serious quantity) after several seconds MCM concerned cannot be accessed at all, only via windows LAN.
That is why I hope that if I manage to copy the files into an empty, brand new 5TB USB attached storage there is a tiny chance that the access to the MCM will be preserved. Although I have got serious doubts.
