Premetto di essere un nwb sia in fatto di ubuntu che di linux in generale, quindi chiedo venia qual'ora la mia domanda venga posta in modo non troppo chiaro.
Sono un possessore di EEE PC ed ho installato su di esso la distribuzione eeexubuntu.
Per aumentare lo spazio a disposizione (dato che l'eeepc possiede solo 4gb) avevo pensato di utilizzare una sd hc da 16 gb, partizionandola in modo da avere circa 10 gb per /usr e 1 gb /home e il resto su /var e swap...così ho fatto... tutto ha funzionato per circa una settimana... e poi PUFF... ieri ha cominciato prima a darmi un pò di problemi e poi ad un riavvio nn caricava più la veste grafica, e mi dava un errore I/O sulla periferica /dev/sdb (ovvero la SD HC)...
ho provato ad usare il comando fsck ma nada... anzi peggio... mi ha restituito un altro errore con qualcosa come superblock... bad blocks.... etc.. ora non ricordo perchè nn ho avuto modo di appuntarlo... fatto stà che ho reinstallato il tutto ovviamente senza scheda (dato che a tutt'ora non viene nemmeno riconosciuta).
Quello che vorrei capire... è possibile recuperarla?
qui di seguito vi posto un pò di schermate...
Codice: Seleziona tutto
davide@EEEPC:~$ fsck /dev/sdb1
fsck 1.40.2 (12-Jul-2007)
e2fsck 1.40.2 (12-Jul-2007)
fsck.ext2: Nessun file o directory durante l'apertura di /dev/sdb1
Il superblocco è illeggibile, o non descrive un corretto filesystem ext2
Se il device è valido e contiene realmente un filesystem ext2
(e non swap, ufs o altro), allora il superblocco è corrotto, e si potrebbe
provare ad eseguire e2fsck con un superblocco alternativo:

con gparted mi dice che non riesce a modificare la tabella delle partizioni, e oltretutto legge una partizione unallocated di 7gb invece di 16...
non riesco a capire cosa fare.. se qualche anima pia mi da una mano gli sarò eternamente grato... grazie in anticipo....
