Space problem in internal HDD for PS3 FAT

hello,

In fact I have a FAT PS3 with 60GByte running Kmeaw CFW 3.55 and i have a space problem, (when I remove every things from intenal HDD, in information system it says 34/55), I Think the 20GByte left are due to Linux installing from firmware 3.21 (i think) purpose and since SONY removed the Linux partition, I was not able to get back my 20GByte Linux partition. My question is if i format my intenal HDD, could i get back my 20GByte left and if there is a problem that could occur when formating of the HDD under Kmeaw CFW.

THX for your replies .

It should have been removed during the update. But it's safe to format under kmeaw. Nothing bad will happen since it's saved on the flash.

OK thanks I understand it is safe to format under Kmeaw, but should i save some things before starting the format ??

If you want any files from the hdd, then you can either use the backup/restore utility or FTP/comegenie's file manager
