NAS 542 BootLoop after debian kernel upgrade and fdisk

Georg

Hello all,

after successfully installing the Debian kernel, I noticed that there was not enough space on the SD card for an update of debian.
Therefore I tried to expand the partion with fdisk and I destroyed something - this was a very big mistake!
Now the NAS is in a boot loop and access is no longer possible.
Is there a solution for this or can I the NAS throw it away?

Best regards
Georg

If you only damaged your SD card, you should be able to generate a new one.

If you damaged the card using fdisk only, TestDisk might be able to repair it.

An SD card is not really designed to run an OS from. Due to a lot of micro writes (logfiles) the memory wears out. When you want to exchange the card, you can google for SD card recommendations for the Raspberry Pi, which has the same problem.

Hi Mijzelf, 

first happy new year!
And thank you for your help. Yes, this was the problem! I had two problems with the SD card, first the boot sector was damaged and the SD card itself had errors.
