The QNXSDP boot cd will mount the hard drives on all these systems released before 2011. FDISK still identifies the 4 partitions as QNX partitions on the new systems, but the partitions are not listed in fs. I am no expert in QNX files systems - obviously - I only use the QNX utilties to increase the size of the 4th partition used for storing user content. I delete the 4th partition, then create a larger partition, then copy the content back to the larger partition. On the newer systems, I can access the content on partition 4 to save and then copy back to the larger partition. Qnx Fdisk How To Overcome ThisAnyone know why these drives wont mount, or how to overcome this issue. Could it be the developer used file permissions to only allow an account imbedded in the firmware of these navigation systems to access the file system Maybe this is a clue.... When Clonezilla enumerates the drive, the partition list is not like the pre-2011 drives which have 4 partitions in Clonezilla and 4 partitions are mounted in the QNX CD. In the new drives FDISK shows 1 of the 4 partitons as extended. In the pre 2011 hard drives there were 4 primary partitions no matter how you viewed the drive. Clonezillas Partition List on new drives (notice sdb2 is not listed) sdb1 11.7GB sdb3 98.7GB sdb4 26.1GB sdb5 1571GB sdb6 502MB Also Clonezilla (using DD) succesfully clones these drive and they work in Navigation system. Thank You. Assuming you are running a shell as super user, then there is no file permission that would prevent you from accessing the drive. You didnt mention which version of QNX you are using, but that might be crucial. The original QNX 6 file system is often referred to as the QNX 4 file system, since it has almost exactly the same format as the QNX 4 file system. It is more limited in use and has somewhat different properties. However it has the nice property that if you create a file, you either get the new file, or nothing at all. With the older version you could get a file where the data never was flushed from the cache. So my first idea is that you are trying to access the new file system with an older QNX version which doesnt know about it. While the partition types for the QNX 4 file system were typically 77, 78 and 79, the types for the newer file system are 177, 178 and 179. I think if you dump the first sector of the file system there is a stamp that might be telling. The other possibility is that MyGig decided to prevent the type of hacking you are trying to do. They could have implemented their own file system, possibly one that is more efficient for their purposes, or they could be using an existing file system, but with an encryption layer placed on top.
