Kdysi jsem odnekud stahl pdf (fmtl10ei.pdf) "SmartMedia Logical Format
Specifications" (to PDF je chranene heslem, bylo nutne se zaregistrovat)
Version 1 May,1999.

Tam doporucuji jako logicky format pouzivat DOS FAT. Jsou tam tabulky
pro kapacity 1, 2, 4 a 8MB. Jinak ta FATka je 12 bitova (jako ma disketa,
ale pozor na velikost clusteru, disketa ma tusim jenom 512B).
Jestli se od te doby neco zmenilo netusim. Zkuste se podivat na SSFDC.

S pozdravem,

Jakub Slajs

P.S. Tabulku prikladam, ale nechtejte po me abych to nejak formatoval :)
