Live-Linux auf USB-Stick mit FAT32- und ext2/3-Partition

[Alexander (HH)]

Moin Moin!

Darf ich mal raten: ext3 war die erste Partition, und FAT32 die zweite. Dreh die Reihenfolge um, fang mit einer FAT32-Partition an, und leg die ext3-Partition dahinter.

Ich frage mich übrigens gerade, ob SD-Karten ab Werk überhaupt eine Partitionstabelle haben. Wenn sich einer der beteiligten Treiber zu dämlich anstellt, versucht der, die Partitionstabelle als Dateisystem zu lesen. Das ginge natürlich gründlich schief.

Linux hat mit Partitionstabellen auf Block Devices keine Probleme, wenn's mir Spaß macht, kann ich auch eine Diskette partitionieren. Windows ist da wesentlich unflexibler.

Oh, und natürlich muß der Partitionstyp für Windows stimmen. Zwingend 7 für NTFS, für FAT gibt's historisch gewachsen einen ganzen Haufen, für FAT32 typischerweise 0x0C oder 0x0B:

Und schließlich funktioniert FAT32 nicht auf alten Systemen (vor Win95 OSR2), jedenfalls nicht ohne zusätzliche Treiber.
