And know think my hdd is totally broken. Is there any way to recover my files. This is the error codes I get whem I type gdisk -l /dev/sda

Please help. Thanks /C

There is no partition table on this disk present according gdisk.
Furthermore the the read errors are also a bad sign.

Without partition table it is impossible to recover any data.
What you could try is recreate the original partition table. And see if you can mount the partition. The partition table is on the beginning of the disk and your data could still be present on the dsk.
The table points to the sectors where the partitions start and end and indentify the type of partition. Whatever you do, donot write anything else to the disk then the original partition table.
Why the table is lost ?? Couldbe a bad sector but could also be a failing disk

The original table is posted in several topics in this forum but here it is once more, this is for a 2 TB disk. Yours is 4 TB so you must adapt last sector of partition 8

ok, thanks for the help. The problem is I have no idea how to recreate the original partition table or how to change to code you provided? Could you give me some pointers? Or what to search for?

Hi Jocko thats the only email address i’ve got that isnt a gmail. Can I change to my gmail adress?

So send an email from your gmail address to our admin address so that we add an exclude rule on yours

---edit---
I updated your account

Hi

In gdisk there is the command "m" it wil give you a list of posdible commands you can give.
One of them is "n" that is used to create a partition entry
When you use it gdisk will ask to give partition number start sector end sector and partition type. The last one has a help command to show a list of avaible types. Pick the one as shown in the example. Same holds for start and end sector except for end sector of partition 8, chose as last sector for this partition the max sector of your disk as shown in the header when gdisk is started (8089916). When done use command "p" to see th result of your work. If you are happy with the new partition table use the command "w" to write it to disk. This last step is required, if you don't do that and just close gdisk the new table is lost and no changes are made to the disk.

I have been trying for hours and googled and can´t seem to understand how to execute commands in gdisk. I should do this in the connected telenet right? This is ehat happens when I try.

I understand that im doing something wrong but cant figure out what. Please help. /C

Yes you must use gdisk on the linux command line, so via telnet client assuming you run our standalone kernel.

you should start gdisk like this (so without the -l option)

Code: Select all

gdisk /dev/sda

;)

Now you should be able to enter commands as explained

PS when you use the -l option it only list drive info, you can use that command later to check if you made the correct partition table
