Received an interesting message when starting backup

Got a new-to-me HP Reconditioned laptop on Monday and started my first backup on Tuesday and got this message.
Never saw anything like it on any computer I have backed up.
I'm hoping some of you experts can give me some help.
I'm still doing backups every morning but don't want to wreck this great laptop.

I am at your mercy and thanks for reading this.

Oh yeah, Windows 10 Pro

Right-click the Start button, click Disk Management to see the drives and their partitions. It's normal to have 3 partitions on Win10 with 2 unlettered, [or maybe more, especially on Upgraded machines]. Mine on an HP Notebook:
Attachment 248849

Thanks
This is a HP Notebook also.
I'll be at the computer and check it out and post here.
Many thanks for your reply. Does it mean all is O.K?

It could be normal and your choice to include or exclude those 2 partitions. I can't say as to the effect of either. I'd go with OK, there should be no change to the drive that would cause a problem.

Thanks
What worried me was the mention of errors.
I've been playing computer for years and NEVER saw that message before.
Here's my SSD. Look O.K.?

That does look normal. Copying sector by sector could carry any issues into the backup. I'd first open File Explorer, right-click the C: drive and Properties then Tools, Check for errors but I doubt it would work with unlettered partitions in which case I'd get the diagnostic software from the maker of the drive and check the health of the whole drive before doing the backup.

If not knowing the make of the drive right-click Start and click Device Manager, look in Disk drives and it may show a model number which used in an Internet Search should give make and model. And that should also show whether it is an HDD/Hard Disk Drive or SSD/Solid State Drive. There's another type, an M.2/NVME.

Well, thank you very much.
I will get used to the error message when I do my backup every day.

Have a great evening, what's left of it. I really appreciate your help.

No errors.

Sorry to butt in, but it does not look right to me, should that 100mb partition be Active? Shouldn't it be the EFI partition which isn't normally marked active?

I wish I knew.
This is a HP computer and I have never seen anything like it.
I wish they had given me a book with it.
