I set up an old PC as a server at home and it was working. Recently I put an HDD in it and it worked just fine but yesterday it was a power outage and when I got home and started the PC it couldn't find sdb1. I know there is an sdb1 because I have data on that partition!
Fdisk and BIOS can see the HDD but fdisk and GPARTED LIVE says 'No partition table' or 'Unknown filesystem'.
If someone needs any information about the PC just ask and I will share.
Please help, I don't want to lose my data,
