HDD I/O error

Sziasztok!

Gyermekeim által nézett meséket tartalmazó HDD-t leejtették. Több év gyűjteménye volt rajt. 1,5 TB lévén mentés nincs. Egyetlen partíció volt rajta ext3 filerendszerrel. Az áldozat egy SATA WD Caviar Green WD15EARS.
Az alábbiak ismeretében valahogy hozzáférhetek még a rajta lévő adatokhoz?

   és innen loopba került, ezt ontja végtelenül. Az adatokat is rosszul olvassa ki: serial number, méret.

   Van egy ugyanilyen másik hdd-m, az így néz ki egy másik géphez csatlakoztatva:

   This does not matter for LILO, but the DOS MBR will not boot this disk.
   Do you want to write this to disk? [ynq] y
   read: Input/output error
   
   sfdisk: read error on /dev/sdc - cannot read sector 0
   Re-reading the partition table ...
   BLKRRPART: Input/output error
   
   If you created or changed a DOS partition, /dev/foo7, say, then use
   dd(1)to zero the first 512 bytes:  dd if=/dev/zero of=/dev/foo7 bs=512
   count=1(See fdisk(8).)

4. Gondoltam kinullázom a partíciós táblát és a másik hdd-ről újraírom, de persze nem férek hozzá:
   

   root@blackbook:~# dd if=/dev/zero of=/dev/sdc bs=512 count=1
   dd: writing `/dev/sdc': Input/output error
   1+0 records in
   0+0 records out
   0 bytes (0 B) copied, 0.00146273 s, 0.0 kB/s

5. A testdisk is csak ilyet logol a partíció keresése közben:
   

   file_pread(3,2,buffer,34(0/1/3)) read err: Input/output error

6. Mint fent írtam van még egy ugyanilyen HDD-m, de azon is rengeteg adat van. Annak elektronikájával esetleg egy hozzáértő kezében mehetek valamire?

Van valami, amit kipróbálhatok, vagy a hdd tartalmáról van listám és álljak neki összevadászni a kollekciót?

Előre is köszönöm az ötleteket!
