There is one thing that seem strange to me. "fdisk -l /dev/hdh" (the 
damaged harddisk) says

    /dev/hdh1             1     30515 245111706   83  Linux

But now "dd" is working with sectors above 245111706, how is that 
possible? Right now it seem to be at 244536664 according to 
/var/log/messages:

Aug  4 15:32:56 d kernel: hdh: dma_intr: status=0x51 { DriveReady
        SeekComplete Error }
Aug  4 15:32:56 d kernel: hdh: dma_intr: error=0x40 { UncorrectableError
        }, LBAsect=244536735, high=14, low=9655711, sector=244536672
Aug  4 15:32:56 d kernel: end_request: I/O error, dev 22:41 (hdh),
        sector 244536672

Best regards,
Jan

Hello folks.
I am trying to determine if XFS offers any performance advantages over EXT3 for our environment. I've been doing some testing between the two using a Power Edge 1650 with 1GB Ram, 2 X 1.4 PIII CPUs and a single 36 GB disk. In my silly little "which file system can untar a kernel tar file the fastest", ext3 has always been faster, I mean significantly. Can anyone help me understand when one would want to use XFS over the default linux FS. 

Thanks in advance. 


Errol
