I guess that it is an issue with the partition table. I have 3 disks in teh same machine. Yesterday I turned on the machine and turn it on this morning. I could not boot. Then I decided to mount them in an external USB enclosure. They all behave the same
Ok, I'm a bit confused here. Do you mean that you install one drive at a time into a USB enclosure to test?
Yes, on another machine
I tried to recover the partition table for 1 disk. I worked, but there are plenty of issues.

As you can see this table is wrong
But cannot mount /dev/sdd6 for example. Disk /dev/sdd6 - 45 GB / 41 GiB - CHS 5481 255 63
Well, yes. A DOS disk (not-GPT) can only have four primary partitions. If you're going to have more than four, then at least one must be an extended partition (typically the fourth partition or /dev/sdd4) and any partitions above 4 live INSIDE partition 4. In the above example, /dev/sdd4 should be type 5 (EXTENDED), then /dev/sdd5 and /dev/sdd6 would live inside /dev/sdd4.
In some ways, that makes sense in that /dev/sdd4 is the biggest partition and could hold sdd5 and sdd6, but I have no idea what this stuff looked like before. Anything I say would be a wild guess. Also the mixture of straight Linux (type 83) and LVM (type 8e) partitions is worrying. Again, without knowing how things were laid out before makes any advice I offer dangerous.
The harddisk (45 GB / 41 GiB) seems too small! (< 60 GB / 56 GiB) Check the harddisk size: HD jumpers settings, BIOS detection...
The following partition can't be recovered: Partition Start End Size in sectors
Linux 1889 40 8 7370 226 24 88064000 [Backup]
testdisk Partition sector doesn't have the endmark 0xAA55
Disk /dev/sdc: 232.9 GiB, 250059350016 bytes, 488397168 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes
I never though that I could lost 3 disks at the same time. I have a copy of the partition table on the disks.
I am trying to run testdisk
How? Via a rescue CD or something? I'm not familiar with testdisk but I see it's available on a bunch of rescue CD images.
