Rescue disk with parted utility for GPT label

[Ai Linh Nguyen Hoang]

 

Hello,

 

I have one USB disk of 3 TB. It is devided into 2 partitions, 1.5 TB each with Linux type (id 83). When using fdisk I can see 2 partions as follows (1)

Device         Boot    Start      End       Blocks            Id     System

/dev/sdb1               1           30000        ......              83      Linux

/dev/sdb2               30001     45600      .......              83      Linux

 

But when using the command "parted /dev/sdb1" in which I run "mklabel gpt /dev/sdb1", the last result I have as follow:

Device         Boot    Start     End         Blocks         Id     System

/dev/sdb1                 1       456001       ........           ee    EFI  GPT

 

It looks like the second partion 2  (/dev/sdb2) is disappeared and the partition 1 become the whole disk with GPT label.

 

Do you have any way to resue this disk? I want it becomes the original state with 2 partitons as above (1)

 

Thanks alot and best rgds,
