Snažím sa naformátovať USB kľúč. Po vymazaní súborov mi zostalo menej voľného miesta ako je jeho kapacita. Čo robím zle?

celkom ma udivuje, ze si tam tie medzery, lomitka, minusky a pod. hadzes uplne, ako sa ti zachce a vobec, ale absolutne vobec ta nesere, ze ti to hazde chyby.

df spustaj s prepinacom -h (t.j. df *MEDZERA* -h, nie df-h), vypise ti to velkosti v rozumnych cislach, nie kryptickych poctoch blokov.

tymto si zatial nic nesformatoval (ak si neskusal nieco viac, nez si tuna napisal), ak sa na to spatne pozres, na kazdy druhy (resp. kazdy okrem posledneho fdisku a tie df) prikaz ti to hodilo chybu.

podla toho, co ale pise fdisk je ten filesystem 8GB velky. kedze subory na disk nejde len tak nahadzat, samotny filesystem ma nejaku reziu. takze realne mozes na takom niecom cakat volnych okolo 7GB +- autobus po naformatovani (az sa ti ho teda nahodou niekedy naformatovat podari).

(a 8GB velky kluc hlavne nie je velky 8GB, ale 8 miliard bytov, co je sice dnes uz akoze vpohode, ale matika mocnin cisla 2 nejako ma lobby vyrobcov medii v pici, takze 8GB kluc ma realne trocha menej, nez je v skutocnosti 8GB - a dementov, co tvrdia, ze G je 10^9 pozdravujem s tym, ze byte nie je velicina co by moc patrila do sustavy SI)

tak si spusti cfdisk, vymaz particiu, vyrob novu, nastav jej typ na MS-DOS FAT32 (na variante imho az tak moc nezalezi) a pak znova naformatuj. ak ti to bude hadzat pri formatovani chyby, citaj manpage a skusaj. v najhorsom si odvaris hlavny disk.

môže, skús ten Gparted - to je v týchto prípadoch fakt užitočná vec :)

Mno... sda mas prvy disk, 180 GB predpokladam, bordel jak svina :) Dualboot win 7 boot disk, potom C, potom D, potom Linux, potom linux swap

sdb je 16 GB, predpokladam ze to je ten kingston. sdb1 je prva particia, ma cca 15 GB, takze tiez dobre.

Hm...
