Dear list,
I have a SSD disk that was booting Gentoo for almost two years. Last
weekend, I moved out. Now when I try to turn on my desktop, it freezes
before loading grub. After a while, it jumps to the second disc, then I
receive a error message because there is a invalid grup installed on
/dev/sdb.
The SSD I mentioned is apparently working pretty well. I booted my
desktop from a Ubuntu usb, and I was able to run several benchmarks
tools and even make a chroot to my Gentoo environment. I've verified the
disk performance, the filesystem (ext4), the inodes, the folder/files,
and everything appears do be normal.
I've also installed and configured grub2 again and was able to boot just
once. Everything worked fine after that boot, but, once again, It no
longer can boot.
The questions are: where should I look for clues? what Information do
you need?
Thank you all,

Simple Check ... Hope its this easy .)
Have you checked the partitions, partition flags, and partition boot
sector on that drive?
( From Frank Steinmetzger )
Look at smartctl for starters.
Do you have sys-apps/smartmontools installed / smartd running?
If the boot sector has wear problems, SMART may show those
bad/reallocated regions on that drive. Not sure how that works with the
TRIM filesystem on SSDs.
Hope this helps.
