X-BeenThere: freebsd-hardware@freebsd.org X-Mailman-Version: 2.1.1 Precedence: list List-Id: General discussion of FreeBSD hardware List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Wed, 10 Mar 2004 15:42:59 -0000 Hi community, it isn't easy to describe and actually it is not a serious problem, but what is the UFS (Unix File System, FFS even?) doing every few minutes? My harddrive (I believe its a IBM harddrive, since the whole notebook is IBM) makes strange sounds every 1-2 minutes if there is _no_ great load or system activity. Don't laugh, but something like: "dack, dack." A frequent routine check ... ? I have read a bit about how harddrives work and what's in them, because I am interessted in such things and what exactly is the reading header doing ? If the harddrive is driven by NTFS i.e., no sounds will occure. So the question is - because no major errors of hardware occured yet - does this mean something to my harddrive or is it just how UFS is working with it? Thanks for help on this! :) -- Ludwig Schreier lu.schreier@t-online.de GnuPG KeyID: 0x024A112A
