[SOLVED] Help with removing a bad HDD and getting GRUB2 menu to reflect the changes

Bill_L · 01-24-2022, 10:34 PM

I am still a newbie, so I may have not worded or included things needed to answer the following question(s).

I have three HDD's in my old HP Compaq DC7700 CMT desktop(A SATA only unit).

Code:

/dev/sdb has Windows 10 and windows 7, and a large unformatted space.
/dev/sda has opensuse,  this drive is a PATA drive connected via a PCI card.
/dev/sdc also has opensuse on it. I put that drive in not knowing there are some bad sectors that can't be 'fixed'.

I tried removing the /dev/sdc from the machine, but on boot it still showed up in GRUB2 boot menu.
SO, I put that 'bad' drive back in.

Can I remove it AGAIN and run 'GRUB2-mkconfig' to get the GRUB2 menu back in order?

In a word: yes.
Although the actual command might differ slightly from what you wrote.
Linux command are case sensitive.

Why do you care ?.
It's just a text entry - no problem unless you happen to select it. As suggested a quick mkconfig will fix it (with the bad disk removed), although I can't believe yast won't have an option to clean it up. Been a while since I looked at opensuse tho'...

There are two things.

1. Your /dev/sdc{x,y,z} might be "mentioned" in /etc/fstab

You should remove it there, i.e. put a # in front of the pertinent line.

2. "grub2mkconfig -o /boot/grub2/grub.cfg" should achieve what you intend.

HTH.

OK, thanks. Got the /dev/sdc out of my way with the grub2-mkconfig -o /boot/grub2/grub.cfg

I will look to see if it is still in /etc/fstab.

So now I can proceed putting Leap 15.3 on the large empty space on the Windows HDD.

BTW, I tried everything I know to get those bad sectors moved, repaired, or fixed. It is a Seagate drive and the SeaTools won’t let get past a generic or SMART test. Three sectors & a once good drive is trash.

Thanks again for the responses.

You click on "Tread Tools" on top of the thread. You'll get a menu with one entry reading "Tread solved" or some such. If need be you can un-solve it later on there, too.
