error the backupt GPT table is corrupt, but the primary appers ok, so that will by used

[Jack]

Hello,
I am making a backup copy on a server. Windows 10 PRO installed. Two SATA SSD drives that work in RAID 1. The drives are exactly the same.

I noticed that one of the drives, when creating a clonezil backup, does it in 4-6 hours, while the other takes 35 minutes.

Sometimes I get the error "error the backupt GPT table is corrupt, but the primary appers ok, so that will be used" and the computer turns off. The second or third time, I manage to make a copy.

I always make a copy on the same HHD drive.

SSD drives have a capacity of 480 GB, while HDD has a capacity of 2 TB.

I tried making a copy on another computer, on different cables, and the speed of copying the drives is the same.

I also noticed that the drives differ when it comes to their recording - screen. And they were started at the same time.

What could be the problem?

I checked HP diagnostic, and it shows that the disks are working.

I make a copy once a week, and periodically check if it was actually made - I start the computer with only the HDD disk - it always works. I don't know if the 4-6 hour SSD copy works, because looking at how long it will take, I give up and choose a faster 35 minute SSD disk.

I'm not an expert in this field. How can I verify the cause of the problem? I was thinking about replacing the SSD, because I think these are of low quality. They work in the server 24/7.

Thank you,
Jack

The prompt is tell you there are some space on the disk which your partition table does not cover all.
You can try to use GParted live (https://gparted.org) to resize/expand the partition(s).

Thank you Steven !
How much space do I need to leave unallocated ?

Just use all of them I suggest.
//NOTE// Backup important data before you use GParted/Clonezilla live. Just in case.
