Re: [tmlug] problema flash usb

[Beratco Matei jr.]

Esti sigur ca e discul de 1GB? Dupa dmseg ar cam fi cel de 8GB (8523MB).
Daca da, atunci e ciudat sa zica "SCSI device sda: 16646144 512-byte
hdwr sectors (8523 MB)".
Daca zicea ca e de 1GB si apoi incerca sectoarele mari (de ex. sa-l
recunoasca de 1GB dar FS-ul sa fie de 8GB) atunci dadeam vina pe ifs-ul
de Win.
Ideea (cauza) la care ma gandeam este ceva de genu: scoti pe cel de 8GB
si apoi il bagi pe cel de 1GB, dar IFS-ul poate nu e facut bine si face
flush la continutul (metadata) celui de 8GB pe cel de 1GB, si astfel ai
avea parametrii fs-ului de 8GB pe discul de 1GB. O problema ca asta ar
putea fi rezolvata cu fdisk.
Deci repet: esti sigur ca e de la cel de 1GB?

Emilian, nu sectorul 32 ar fi problema, ci cele pe la 16.000.000. Cel de
32 poate are probleme ca se blocheaza controllerul de flash.
Si daca intr-adevar a trimis dmesg-ul de la cel de 1GB, atunci problema
cred ca e mai serioasa.

Hm, nu stiu, sectorul 32 pare a fi cam prea "la inceput" si poate
ocupa ceva zona importanta.

Daca nu ai nevoie de datele de acolo as incerca mai intai un dd
if=/dev/zero of=/dev/sda ca macar sa stiu ca nu are nimic pe el care
sa incurce fdisk.

Apoi dai un fdisk si vezi daca mai poti reface vre-o partitie.

Poate gasesti vre-un filesystem ce se descurca si flash-ul tau. Stiu
ca in tinerete imi facusem eu ceva f. primitiv sa pot folosi dischete
stricate la sectorul 0. Cate jocuri or carat dischetele alea...

Salut,

Am un USB drive de 1GB, pe care l-am formatat ext3 si l-am folosit in win cu
IFS driver (http://www.fs-driver.org/) o buna bucata de vreme.

Recent am mai luat un drive de 8 GB pe care l-am formatat si pe el ext3
si l-am folosit pe acelasi calculator in win. Doar ca a aparut o mica
problema
cu drive-ul de 1 GB:

and so on ....

Si in win apare cu marimea de 8 G.
Mai am vreo sansa sa-l resuscitez ?

Nici cfdisk si nici fdisk nu vor sa aiba de-a face cu el.
As putea macar sa-i declar o partitie in zona valida de memorie cumva ?
