errore cw

ciaoa tutti, sono riuscito ad installare correttamente clocwork, ma qualsiasi cosa cerchi di fare spunta questo:

E: can't find misc
E: failed to find "cache" partition to mount at "/cache"
E: can't mount /cache/recovery/command
E: can't find misc
E: failed to find "cache" partition to mount at "/cache"
E: can't mount /cache/recovery/log
E: can't open /cache/recovery/log
E: failed to find "cache" partition to mount at "/cache"
E: can't mount /cache/recovery/last_log
E: can't open /cache/recovery/last_log
E: can't find misc
E: failed to find "cache" partition to mount at "/cache"

esattamente cosa significa? c'entra qualcosa con il fatto che le app spesso e volentieri mi crashano?
grazie a chiunque mi dia una mano! ;)
