[HD USB]come individuo il device giusto?

[clemmy]

ho callegato, a computer spento, alla mia linux box (knoppix 3.3 - kernel 2.6.4) un hd esterno usb...credo che come moduli sia a posto, ma non lo riesco a montare, non so che dev usare..nei vari how-to son tutti che mettono /dev/sda ma da me non va bene..vi posto un po di output che ho guardato x cercare invano di capirlo da solo..

* i cd-rom sotto emulazione scsi sono /dev/scd0 e dev/scd1, ma /dev/scd2 non è l'hd esterno..

da usbview vedo senza probl la mia unità..

[clemmy]

dopo aver scollegato l'hd, con dmesg mi viene queste righe nuove:

e dopo averlo ricollegato compaiono invece queste:

scusate la lunghezza ma non sapendo che info dare ho preferito abbondare...grazie

io il mio hd da 120GB diviso in due partizioni da 60 li monto così:
#mount

[pigio]

#mount /dev/sda1 /mnt/hd1
#mount /dev/sda5 /mnt/hd2

[clemmy]

no, /dev/sda non me lo prende..

[pigio]

nella compilazione del kernel hai inserito i supporti per l'usb? [Device Drivers -- USB support -- Support for USB]
altrimenti non riesi a fare niente, te lo chiedo perchè quando avevo provato ad installare la knx 3.4 cvs non me li aveva installati

[figulus]

Anche io avevo lo stesso problema, ho risolto con

# modprobe ehci-hcd

E comunque se non è sda prova con sdb !

[unarana]

# cat /proc/partitions

Ciao

[clemmy]

si,a livello di supporto USB sono a posto, infatti vedo un sacco di info a proposito di st'hd,compresa la marca del produttore e il modello..solo che non riesco a montarlo x' non so che dev sia..sul disco c'è una sola partizione ,xò mi è venuto in mente che potrebbe essere una partizione logica anzichè una primaria, quindi potrebbe essere sda5...
appena riesco a farmelo reimprestare ci provo e sennò provo cat /proc/partitions...

la cosa che mi fa incaXXare è che prima di restituirlo ho provato ad accederci da WinXP, ma come lo collegavo si freezava tutto..probabilmente è colpa dei driver via 4in1,xò..no comment!

[gurutech]

prova a dare un'occhiata a sg_scan e sg_map del pacchetto sg3-utils, potrebbero aiutarti!

[clemmy]

mi son fatto riprestare l'hd..ma c'è qlc che non va
sg_scan e sg_map non lo vedono

[clemmy]

porca miseria forse ho trovato il problema! collegando l'ho mentre sono in console mi viene fuori FATAL: module sd_mod not fount , cosa che dal dmesg non viene fuori assolutamente!..credo che sia questo il probl...anche perchè ho visto che st'hd è /dev/sg2 (sg0 e sg1 sono i CDrom), e proprio sg2 non viene associato a nessun dispositivo di blocchi

knoppix@computer:~$ sg_map
/dev/sg0  /dev/scd0
/dev/sg1  /dev/scd1
/dev/sg2

ora la domanda è: come lo metto sto modulo? ho provato # modprobe sd_mod ma non lo trova..devo ricompilare immagini...ma come faccio a sapere a quale voce del menuconfig corrisponde?

[clemmy]

bingo!ho caricato col kernel vecchio (quello nel quale io non avevo messo le mani) e funziona!peccato che non riesca a montare ugualmente!

knoppix@computer:~$ sudo mount -t vfat /dev/sda /home/knoppix/Desktop/
mount: tipo fs errato, opzione non valida, superblocco su /dev/sda danneggiato,
       o troppi file system montati
knoppix@computer:~$ sudo mount -t ntfs /dev/sda /home/knoppix/Desktop/
mount: tipo fs errato, opzione non valida, superblocco su /dev/sda danneggiato,
       o troppi file system montati
knoppix@computer:~$ sudo mount -t auto /dev/sda /home/knoppix/Desktop/
mount: si deve specificare il tipo di filesystem
knoppix@computer:~$

considerando che ho appena smontato un hd da 80giga non credo di aver troppi fs montati

considerando che ieri da winXP (non a casa mia ma dal proprietario dell'HD) funzionava non dovrebbe essere danneggiato

considerando che il tipo di fs + che fat o ntfs non può essere e che non dovrei aver dato opzioni sbagliate i conti non mi tornano

[gurutech]

Originariamente inviato da clemmy

knoppix@computer:~$ sudo mount -t vfat /dev/sda /home/knoppix/Desktop/

prova

knoppix@computer:~$ sudo mount -t vfat /dev/sda1 /home/knoppix/Desktop/

sd_mod corrisponde a SCSI DISK SUPPORT

edit:
oops! ma stai cercando di fare mount sulla directory Desktop ?
dovresti farne un'altra o usare un altro mountpoint

knoppix@computer:~$ mkdir /pippo
knoppix@computer:~$ sudo mount -t vfat /dev/sda1 /pippo

[DjMix]

Non è sda. È sdaX, con X >= 0

[clemmy]

grazie! ora funziona tutto!!!FINALMENTE!!!
