My Fujitsu P1610 came with a `80 GB' hard-drive. SuSE reports that the whole drive is in fact 74.5 GB, which came divided into two 37.2 GB partitions. The first partition had Windows XP Tablet installed, using 3 GB. I chose to shrink the Windows XP partition (after turning off the swap in Windows XP and de-fragmenting) to 30 GB total. As I had only just purchased the P1610, the first partition did not require any de-fragmenting. The second Windows partition I chose to delete, replacing with an extended partition which will contain the Linux partitions.
Before re-sizing the first Windows parition, SuSE suggested a 1.4 GB swab, 14.4 GB root partition and 21.3 GB home partition be created in the space freed by deleting the second Windows partition. I re-sized the suggested Linux partitions to fill in the space freed by re-sizing the first Windows partition.
Unfortunately, the installer failed while some time after re-sizing the first Windows partition, I think when it was trying to create the first Linux partition in the newly `freed' space. SuSE's partition program refuses to work further on the partition, it mis-identifies the first partition as a Linux rather than Windows partition. The Windows partition is corrupted in some way, but rebooting Windows XP results in chkdsk being run, and correcting the problem. No bad blocks or links were detected. Re-running the installation program again allows the partition table to again be edited by the SuSE installer.
