WARNING: /pci@1f,0/pci@1,1/ide@3/dad@0,0 (dad0):
Uncorrectable data Error: Block 1

DIOCTL_RWCMD: I/O error

Ready to get manufacturer's defect list from unformatted drive.
This cannot be interrupted and takes a long while.
Continue? n
[disk unformatted, no defect list found]

The disk must be formatted because I can mount the partitions. Should I say yes to getting the manufacturer's defect list?

Thanks

Rebuild os image on separate disk, mount old partitions, and cp data to new disk. You always want to use a mirrored root disk to avoid this senario. Disk Suite can be used as a cheap solution or veritas vm for a enterprise solution.

SYSTEMD-GPT-AUTO-GENERATOR(8)				    systemd-gpt-auto-generator				     SYSTEMD-GPT-AUTO-GENERATOR(8)

NAME

       systemd-gpt-auto-generator - Generator for automatically discovering and mounting /home as well as discovering and enabling swap
       partitions, based on GPT partition type GUIDs.

SYNOPSIS

       /usr/lib/systemd/system-generators/systemd-gpt-auto-generator

DESCRIPTION

       systemd-gpt-auto-generator is a generator that automatically discovers /home and swap partitions and creates mount and swap units for them,
       based on the the partition type GUIDs of GUID partition tables (GPT). Note that this generator will execute no operation on non-GPT
       systems, on systems where the units are explicitly configured (for example, listed in fstab(5)) or where the mount point is non-empty.

       This generator will only look for partitions on the same physical disk the root file system is stored on. This generator has no effect on
       systems where the root file system is distributed on multiple disks, for example via btrfs RAID.

       This generator is useful for centralizing file system configuration in the partition table and making manual configuration in /etc/fstab or
       suchlike unnecessary.

       This generator looks for swap partitions using GPT type 0657fd6d-a4ab-43c4-84e50933c84b4f4f. It looks for /home partitions using GPT type
       933ac7e1-2eb4-4f13-b8440e14e2aef915.

       systemd-gpt-auto-generator implements the generator specification[1].
