[Pavel Stárek]

No vždyť ten výpis ti radí co máš zkusit:

/usr/bin/cdrecord: Some drives do not support all blank types.

/usr/bin/cdrecord: Try again with cdrecord blank=all.

Takže zkus zadat:

/bin/cdrecord -v gracetime=2 dev=/dev/hdc speed=4 -tao driveropts=burnfree -eject blank=fast -force

Nebo v k3b si nastav typ smazání místo "rychlé" na "úplné".

[Pavel Stárek]

Oprava, samozřejmě mělo být:

/bin/cdrecord -v gracetime=2 dev=/dev/hdc speed=4 -tao driveropts=burnfree -eject blank=all -force

Citace puvodniho prispevku:

Vsechna jina media cd-rw vymazu pouze 8cm ne, ale tusim ze to slo ani blank=all nepomaha.

[Pavel Stárek]

Jééé, no četl jsem to příliš rychle To se omlouvám.

[55.lukas]

Moc som nestudoval diskusiu, ale .... Nie je problem v rychlej napalovacke a pomalom rw?

Ja som si kupil na blbosti tiez male cd-rw a mozem len raz vypalit, zmazat sa mi to uz neda.

[Pavel V.]

Neco na tom bude. Jeste jsem experimentoval. Zkousel jsem ho vymazat rychlosti 2x a zda se ze medium je kaput. Tak na 50% si myslim ze jsem ho uz mazal, ale fakt nevim :-|

[fakenickname]

cdrecord -v dev=/dev/cdrom blank=all A jestli tohle nezabere tak je to medium asi potencionalne v kosi

[Pavel V.]

Nejde.
Zkusil jsem jeste demo Nera a to si take neporadi.
Necham ho vymazat u znameho a pouziju ho jako CD-R. Skoda.

[DNA]

škoda je s tím strácet čas, lepší zajít na pivo a použít to jako tácek

[otasomil]

Ja s tim mel tez problemy v Gcombust CD-rw neslo smazat ale pak jsem prisel nato ze je treba nastavit rychlost a to na hodnotu minimalne jaka je udana na CD-RW tj pokud mas treba 8-12x tak nastav 8x zvol "fast" a musi to jit smazat. Slo to tak i v k3b v slaxu

[Pavel V.]

Problém byl v nedostatečně kompatibilní mechanice BENQ 1620.
