Because in order to access the disk file system directly, without the mycloud’s operating system getting in the way, you need direct access to the SATA interface. It’s like asking why you can’t get direct access to the hard disk on a Windows PC…
Then, has anyone found a method that DOES NOT require “reformatting the ENTIRE disk”?
Have you read the entire thread? Most of the suggestions involve simply overwriting the OS partitions.
Is this proprietary? If so, then WD needs to change that because I AM NOT accepting that I just need to delete my data. That’s bullshit and scammy.
It’s a Linux ext4 filing system. The only proprietary bit is the design and use of the partition system to support limited RAID on critical partitions, and create the user space partition. There’s nothing ‘bullshit or scammy’ about that.
Provided you can get the mycloud working again, it doesn’t matter what happens to the data on it; to recover your data, just go to your backup device. You do have a backup for the mycloud, don’t you…?
Often when one bricks the My Cloud they cannot access the My Cloud via SSH. When this happens about the ONLY way to access the My Cloud hard drive is to open the My Cloud enclosure. At that point it is a trivial matter to remove the drive and connect it to either a SATA to USB adapter or direct to a desktop computer with a SATA port/cable.
If one can still access their My Cloud via SSH then it may be possible to fix certain issues and or push a firmware upgrade to the My Cloud. Do a forum search and you’ll find several threads on how to perform a firmware upgrade via SSH.
The My Cloud is a network attached storage (NAS) device, NOT an external USB hard drive. Like many low cost NAS devices where the NAS OS is on the hard drive, if the hard drive becomes inaccessible the NAS OS becomes inaccessible right along with it. At that point generally one has to pull the hard drive to gain access to it.
The OS on the My Cloud is a form of Linux. Generally the Windows OS cannot access a Linux formatted hard drive without some additional drivers. The easiest method is to use a Linux boot disc to boot the computer the My Cloud hard drive has been attached too.
Do a subforum search for “unbrick”. There are several methods that involve just pushing the “img” files to several of the My Cloud partitions and don’t involve destroying existing user data. But again, to do so generally requires one to remove the hard drive from the enclosure and connect it to a computer.
Unbricking a My Cloud IS NOT OFFICIALLY SUPPORTED by WD. If you unbrick you do so at your own risk !!! Generally the official method is to contact WD Support and RMA the My Cloud unit which may cost one money if not under warrantee.
Several of the unbrick procedures, like this one that I’ve used several times, indicate how to push the “img” files (kernel.img, config.img, rootfs.img) files to three of the partitions. One just has to obtain one of the backup archive type files from one of the unbricking threads (the link previously posted in this post includes one). You just need to ignore most of the preceding stuff about partitioning and formatting so long as all the partitions are intact. Note use the correct “sdx” entry for your setup.
As some of the unbricking guides indicate use a Linux Boot Disc (also called a Live CD). One popular Linux distro is Ubuntu. One downloads and burns the ISO file to a DVD disc or to a USB flash drive, then one boots their PC with the DVD or USB flash drive. From there one can use GParted if needed or can use the command line terminal to issue the commands to push the IMG files to the various partitions.
The linux swap partition is disk space used by the operating system to swap out parts of program memory to make room for other programs. When the swapped out memory is required for the program to continue it is read back in from swap space and some other area of memory is written to swap space.
I tried to follow this instruction with the 2TB Image and a 4TB HDD, but unfortunately I had to skip #14 and 15 because I didn’t received an error. After typing in unit s + p, I only got an overview about 2 existing sectors (not 4 as it’s written here). Furthermore, the start sector of the last partition (which was 2 in my case) was 77056s.
I continued with step 16 (but didn’t got a warning again) and finished the instruction, but currently I only get a permanent white LED and can’t connect with the software.
Do you have an idea what I’m doing wrong or another solution?
