uratowac twardy dysk

witam,
wysypal mi sie twardziel, prosze o Wasza pomoc,
bo moze jeszcze da sie go uratowac.

jest to drugi twardy dysk w moim komputerze (Seagate 80GB, kupiony w marcu 2004)
dysk w wiekszosci przypadkow jest wykrywany przez BIOS,
ale zdarza sie, ze juz od samego nie zostaje wykryty.

jezeli juz uda sie uruchomic system (Linux) to po wydaniu komendy
#cfdisk /dev/hdb system staje (top pokazuje zuzycie 99% zasobow wa)
a po minucie wyswietla ERROR, nie mozna skomunikowac sie z dyskiem.

Jezeli wystartuje komputer z Windowsa, wybiore Zarzadzenie Dyskami
to musze poczekac minute az na liscie pojawia wszystkie dyski
wlaczie z tym podejrzanym, na ktorym zaznaczone sa wszystkie partycje
(oczywiscie Unknown, bo sa to partycje sformatowane ext3 i jeden linux Swap)

Proba usuniecia dowolnej partycji konczy sie niepowodzeniem
(Blad w polaczeniu z dyskiem)

Odrzucam awarie kontrolera, bo te same objawy wystepuja po podlaczeniu
do innego komputera. Po telefonie do firmy, ktora zajmuje sie odzyskiwaniem
danych i przedstawieniu objawow dowiedzialem sie, ze na 90% to
uszkodzona glowica i odzyskanie danych bedzie kosztowalo od 800 do 1500zł.

nie sa to dla mnie az tak cenne dane, a moze da sie je odzyskac
jakimis domowymi sposobami? a moze to cos zupelnie mniej powaznego?

przetestowalem dysk narzedziami Seagate Tools i otrzymalem taki raport:

Diagnostic Results:

Seagate DiagATA Quick Test Result: Failed
    Recommendation:
    The "Quick Test" is adequate for most situations.
    Consider running the "Full Test" which
    verifies each sector on the drive if you need to run a more
    comprehensive diagnostic.

******************************************

Recommendation:
If you are not experiencing data loss and SeaTools reports File
System Structure errors, they may be caused by a lock-up or
failure to shutdown Windows correctly. Many times, these errors
may be repaired through normal system maintenance which
includes using the Windows provided "Defrag" and
"Scandisk / Chkdsk / Error Checking" utilities.

If you are experiencing a hardware error, you should isolate
the cause and replace the failing component. If you are unsure how
to proceed with repairs, contact a computer professional. After
completing any maintenance tasks, run SeaTools again to
verify that all errors have been repaired. If errors continue to
occur, the system may not be stable. Again, contact a computer
professional.

If you have experienced a data loss, cease drive operation
immediately. Professional data recovery service is the best
option to recover your data.
