Disketova jednotka TEAC FD-CR7

Interni floppy jednotka 3.5" kombinovana s cteckou pametovych karet 6-in-1. Floppy jednotka se pripojuje primo do zakladni desky pomoci bezneho plocheho kabelu, z diskety lze tedy normalne bootovat. Ctecka karet se pripojuje pomoci specialniho kabliku do USB konektoru na zakladni desce anebo pridavne USB karte. USB 2.0.

Slot A : CompactFlash (Type-I&II) , MicroDrive
Slot B : SecureDigitalCard , MultiMediaCard, MemoryStick (Pro), SmartMedia

Interni machanika ma tedy dva nezavisle rozhrani. Indikacni LED dioda je ale sdilena mezi disketou a cteckou karet.

Disketova jednotka je pod Linuxem bezne podporovana, zadny problem, je to uplne obycejna disketova jednotka (A:/B: v DOS, /dev/fd[01] v Linuxu). Ctecka pametovych karet se chova podobne jake jine externi USB ctecky (/dev/sdaX). Ubuntu Linux dokonce karty sam pripojuje.

Testovano na Ubuntu 7.04 i386, kernel 2.6.20-15-generic i686.

Zajimave rozsireni pro starsi pocitac pokud casto pracujete s datovymi kartami. Mnohe nove PC se jiz s podobnou mechanikou dodavaji, nektere maji jen ctecku karet bez podpory disket.
