USB stick - Read-only

Sziasztok,

2 napja még jó volt, pont addig amíg meg nem kaptam. :D

[root@lock ~]# fdisk /dev/sdb


Welcome to fdisk (util-linux 2.28.1).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.

/dev/sdb:

A hdparm nem segít, ugyan úgy írásvédett marad. Nincs rajta semmi pöcök manuálisan.

A gparted ezt mondja(csak terminálban, a guiban a devicesben nem is látszik.):

Unable to open /dev/sdb read-write (Read-only file system). /dev/sdb has been opened read-only.
/dev/sdb: unrecognised disk label


/dev/sdb1 nincs. Ennek annyi, vagy lehet még tenni valamit érte?
