chkdsk doesn't run and I'm just sad

[bibbedybob]

A friendly hello to you all

 

First of all the brief backstory to my problem:

• Two hdd in a hdd docking station and one hdd on a sata to usb adaptor
• All on the same powered usb hub
• suddenly the two hdd are not recognized anymore

During a transfer of some files with TotalCommander I got some errors from the file verification. Soon the two drives were gone. In fact they were still visible in TotalCommander and WinExplorer, also in DiskManagement (as RAW) but i cannot access my data.

 

So far I tried:

• changing the hdd to another sata usb adaptor on different usb ports
• using the Error Checking Tool which said it cannot access the drive
• using chkdsk /f/r which says (transladed roughly) "the version and state of the volume cannot be detected and chkdsk is aborted"
• using Easeus Partition Master with no option to repair the file system

Do you have any idea what else I could try? (he asked desperately and with tears and insanity in his eyes )

 

If it helps I could provide scrennshots (with german text though)
