HDDs after initialising in Synology not working anymore GPT lost
Hi folks,
I am lost what is going on here. It would be fantastic if you are able to help me to bring my disks back to live. Code:
================= Code:
================= Thanks in advance Guido |
Try:
Code:
blockdev --getro /dev/disk2 If it prints "1" then the device has been set read-only. |

sudo gpt -vv show /dev/disk2 gpt show: /dev/disk2: mediasize=3000592982016; sectorsize=512; blocks=5860533168 5860533168 = 732566646 (4k) sudo dd if=/dev/zero of=/dev/disk2 bs=4k seek=732566500 --> writes properly 46 blocks Any idea? I really tried anything I can find. But I somehow need to recover the GPT. |
Can't hurt to run smart tests or the OEM diag suite.
Some of the nas products do some odd stuff. Could be using in a a different way than we'd think in linux. Put the drive back in the nas and run diags maybe. |
I already ran SMART with the WD native tool and everything comes back fine. I can even write with DD to the complete disk and even to the last block. The thing I am wondering at the moment if this has something to do with the 4k disk itself as I am not able to dd with 512 byte only 4k and bigger. I put the drive already back to the NAS and that was my initial try but no chance to get this drives back to life there. That was actually the reason why I bought the SATA III to USB adapter. Very strange...but something must have done something do the disk I am not aware yet.

Can you post the error from the system log?
|
I'd think a modern nas could initilize the drive. You say you dd'ed to it??? I'd assume it should need at least a standard mbr written to in now. Does gparted allow you to change it?
|
The Synology just comes back with cannot format...and can't remember exactly what error message. Gparted will tell me input/output error and when I want to initialise a new GPT it will fail. And yes I can dd to it without any issue.
