Liebe Community,
ich wollte ein umfangreiches Backup persönlicher Daten machen,
u.a. diverse Firefox-profilordner incl. Cache. Diese Profile belegen
laut Windows Eigenschaften-Anzeige1,2 GB in 24310 Dateien und
9411 (Unter-)Ordnern.Während des Brennens kam es nun (s.log)
mehrfach zu Aussetzern mit den Meldungen "Waiting for buffers to recover...
........Waiting for hard disk activity to reach threshold level...".
Laut Imgburn-Supportforum tritt dies auf, wenn die Festplatte dem
Brenner die Daten nicht schnell genug liefern kann. Ist es möglich,
dass genau das hier hier durch die komplexe Ordnerstruktur und der
Verteilung der Datenmenge auf tausende kleine Dateien der Fall war?
Mir war bei früheren Gelegenheiten schon aufgefallen, dass das Kopieren
der Profilordner ungewöhnlich lange gedauert hat. Mit meinen Festplatten
(2 X Seagate 1 TB)habe ich ansonsten keine Probleme. Die lange Pause
um5:18 geht darauf zurück, dass Imgburn mir für eine der zu brennenden
Dateien eine "Access Denied"-Fehlermeldung gegeben hat und ich 20 Minuten
brauchte,um festzustellen, dass diese von Sophos zu unrecht in Quarantäne
gehalten wurde.Die "Verify failed" Meldung war, wenn ich es richtig verstehe,
dadurch verursacht, dass beim Vergleich einige der Dateien auf der Fesplatte
nicht gelesen werden konnten (einige der Firefox Profil-Dateien sind offenbar
standardmässig zugriffsgeschützt, das hatte ich auch beim Kopieren schon festgestellt).
Wie vertrauenswürdig ist nun das Ergebnis eines über 30-minütigen Brennvorgangs....?
-danke

Edit: wie macht man übrigens mit Nero Disc Speed einen vollständigen Qualiscan
einer DL-DVD? Standardmäßig wird offenbar nur eine Schicht gescant (obwohl
die gesamte Kapazität erkannt wird) und ich finde keine Infos, ob oder wie das zu
ändern ist.
