Few days ago my old fujitsu has developed bad sectors few just 16k.
With a friend we decided to make a low level format and ..we do ,after that this unit it isn't recognised by the BIOS and clicking . The model is MPE-3084 version C023 . The data on this thisk is not important it was on my router so I can to reinstall linux on it but ...how can revive ?
I read before to register on forum and I think it's a problem with HS table ...
Thank you for the time wasted to read this story

Problem was solved with HDDL . I write correct module in ram then the unit doesn't make noise specific "clicking" after that i was able to write the HS module in HDD.
After reboot the unit was identified as 4.3 GB but I use the function restore manufacturer size NHPA (uncut factory size) then capacity restored at 8.4 GB.
Now the unit is full functional
