====== HDD Resurrection ======

V neděli 4. 11. mi nechtěl naběhnout HDD. Ozývaly se z něj zvuky, jako když se snaží něco načíst, ale nedaří se mu (né takové ty jedovaté, které říkají "právě-si-ničím-plotny-a-hlavy", ale takové ty "jojo-tady-to-někde-mám-už-to-bude". Pak se ale po chvíli zastavil a hledání vzdal (nejspíš to vzdal BIOS, který po chvíli nabootoval bez disku). Po několika restartech a hýbání s konektory jsem přepojil SATA do jiného portu a disk naběhl. Voilá, nejspíš mi odešel port na boardu. Nu což, mám jich ještě 8 :-)

V úterý 6. 11. se mi to ale přihodilo znovu. Tentokrát žádné přehazování nepomohlo. Nabootoval jsem SystemRescueCD z flashky a jal se experimentů. Kernel se disk snažil zinicializovat při bootu:

Další pokusy o reinicializaci skončily stejně. Projistotu, reinicializace se prování příkazem (kde N je číslo sběrnice, kde je SATA -- vyzkoušel jsem experimentem):

<code>
echo "- - -" > /sys/class/scsi_host/hostN/scan
</code>

Disk jsem také zkusil zapojit do SATA toasteru a přistoupit k němu ze SystemRescueCD nabootovaném z flashky, ale neúspěšně. Vadný disk toaster vyhodnotil asi následovně:

Poslední disconnect jsem ho raději odpojil, bůhví co ten toaster má za lubem. Když jsem byl již totálně zoufalý, disk jsem dal do hliníkového sáčku na uchovávání sypaných čajů a vrazil do mrazáku (už smířen s tím, že nenaběhne). Po asi 20ti minutách jsem disk vyndal, zapojil do ještě běžícího počítače a co se nestalo, disk vesele zachrochtal a funguje. V době psaní tohoto úryvku kopíruji data na disk nový :-)
