Knoppix 3.8.1 CD boots on my PC successfully and mounts my SATA drive correctly such that I can view and edit files on all the partitions.
However parted and qtparted fail to resize a FAT32 partition reporting the message "The information sector has the wrong signature (0)".

Any suggestions? PC has Asus A7V600-X motherboard with VIA 8237 SATA and single SATA drive attached. Output from parted:


Using /UNIONFS/dev/sda
Information: The operating system thinks the geometry on /UNIONFS/dev/sda is
9729/255/63. Therefore, cylinder 1024 ends at 8032.499M.

ignore.

qtparted reports same error when attempting to resize /dev/sda partition 7

Resolved - with Knoppix 3.9 parted move/resize works fine with for my SATA drive.
