RAMdisk įrengimas minecraft serveriui

Sveiki,

Nusprendžiau paspartinti savo minecraft serverio veiklą. Ir radau štai tokią pamoką ramdisk įrengimui - http://www.minecraftwiki.net/wiki/Tutorials/Ramdisk_enabled_server . Tačiau, pastebėjau jog ši pamoka padaryta gerokai pažengusiems programuotojams arba minecraft serverių kūrėjams. Šį ramdisk pavyko įrengti, bet kaip visad iškilo ne didelių problemų.

Pagal idėja reikia turėti 3 atskiras direktorijas - minecraft, minecraft_ramdisk, miencraft_backup. Pirmoje direktorijoje turi gulėti minecraft serverio failai, antroje turi būti "world" katalogo failai, o trečiame turi siųstis žemėlapio kopijos. Na, pradėkime nuo to kad pas mane šiek tiek nesutampa, minecraft kataloge guli visas serveris kaip ir turi būti, bet antrame kažkas ne to, į minecraft_ramdisk direktorija kopijuojasi visi minecraft serverio failai, mano manymu to neturi būti. Tai klausimas bus toks dėl ko čia taip gali būti? Ką darau ne taip? Ir kas turėtų akyvaizdžiai pasikeisti? Iš anksto labai dėkoju už pagalbą.

Atsidarai scriptą ir žiūri kodėl siunčia. Duomenų perdavime klaida,dėl to ir kelia į kitą direktoriją.

Regis nematau jokių klaidų.
