Hi Örjan, Found the problem. Windows (or DOS) partitioned the drive for 256 byte sectors even though the drive has 512 byte sectors. This isn't immediatly apparent until you start comparing the partition sizes in the partition tables to what fdisk says. Thanks alot M$! From looking at the unpatched code in dmraid, it looks like Heinz was trying to get around the problem of M$ useing 256 byte sectors for partitioning and Linux fdisk useing 512 byte sectors. It looks like he was trying to locate the partitions with minimal use of the partition tables and treating them as if they were stacked one after the other. This doesn't always work, especially for extended partitions. The patched version is written to spec and depends on the partition tables. It works great for me because I used linux fdisk to create all my partitions B~b. Linux fdisk manages to hide this when you display your partitions and shows everything as 512 byte sectors. So, how to fix this? Well for starters, how does Linux fdisk find out what the sector size is, boot sector (possibly)? The partition tables themselves do not contain any hint as to partition size. You can't really use an error condition to determine it, it might be a real error. What happens when some of the partitions are from M$ and some of them are from linux (God forbid!)? I need to find out how Linux fdist works this out and if it is a complete solution or a "works for most" solution. At the very worst, dmraid from the command line could have user interaction to flag windows partitions and run a config file at boot time. Now that would solve all the problems, except for user friendliness! Of course you could always replace dos.c with something as big as dmraid, but jeez. It might turn into a bigger headache hooking it up than fixing what you have. Hey, Dick Marinus, do you have any ideas or comment on this? Oh yea Örjan, all I can say is "OUCH".
