4TB My Cloud disappeared- Fast blinking blue light! HELP

#66

did you do the mkfs.ext4 /dev/sda3?

#67

Nop… and since i’m on it, should I do this for sda1,4 and 7 as well?

#68

:smile: I just did what you told me. (just on 3, pls let me know if It was recommended/necessary to run the same command on sda1, sda4, and sda7)

Anyway, just did it (for now) on sda3.
COULD run the rest of the steps
After reboot, I was able to enter the recovery mode (first time with a different IP & the real MAC ADDRESS) now… the spinning wheel, I read (by inspecting the element on chrome, that is actually a percentage…so, should it read a % or just spinning empty is ok?

#69

sda7 and sda4 will need the mkfs.ext4 at some point. When you did the dd to those partitions. You basically made the partitions uninitialized.

U P D A T E !!! BLUE STEADY LIGHT BUT (several BUTs)

I got to apply the firmware, and then a series of menus BUT(1) on the first menu it returned unknown error. I thought that was the end of it, however, I clicked OK and the process continued, it ask my for admin user & pass and more

  • The process finilzed and then… I got a drive whose status was CAUTION (no explanation)
  • No data,

BUT(2)

Before creating anything, I went back the USB flashdrive boot, typed the following sequence

mkdir /mnt/sda
mkdir /mnt/sdb
mount /dev/sda2 /mnt/sda
mount /dev/sdb1 /mnt/sdb
cd /mnt/sda
ls

Sure enough, my data is still there.

So, is there any way to accessing it when I boot the normal way? Because if I am afraid the if create a RAID mode i will destroy my data…

BUT(3) - On HOME, Diagnosis says CAUTION

BUT(4)


Nothing seems to be wrong (except for not seeing my data)

Please tell me there’s a way. I feel that I’m really close

One thing you can do is to go back to the USB boot drive.
mount /dev/sda3 /mnt
ls -a /mnt
umount /mnt
mount /dev/sda7 /mnt
ls -a /mnt
See if you see the same thing that I see on my device.

Try to enable ssh on the device. Hopefully you can ssh into the device and run some commands.
PS Do not execute any command on /dev/sdax.

Sorry I meant /dev/sda7 and /dev/sda4. /dev/sda7 looks close.

#74

/ # mount /dev/sda4 /mnt
mount: mounting /dev/sda4 on /mnt failed: Invalid argument

#75

Did you do an mkfs.ext4 on /dev/sda4? This is my last reply today it’s almost midnight.

#76

I ll try it in a bit and post the result. Tx

Well, 7 kinda looks like yours, not 4
