Also of interest, diskdrake had no problem taking the resulting disk, deleting the 8GB partition, and defining a partition to use the entire rest of the disk. Assigning to maintainer and CC'ing "basesystem group" maintainers CC:
(none) =>
basesystem, marja11 fdisk has some known limitations. For this disk you should probably use something like parted (or diskdrake which is based on the same underlying code). I made it work by using fdisk to write the MSDOS MBR and then diskdrake to create the partitions. The problem is that diskdrake won't write an MBR and fdisk (which I think is all we supply on the rescue disk) won't create all of the partitions. Not intuitive. What size did you use for the extended partition? That seems to be the problem

Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.

pterjan Hmm, possibly, but I don't remember giving a size for the extended and I don't see why fdisk would max out at 365G (or so) on a 1TB disk. The first extended partition was the 24G swap, and I don't see the correlation. But if you can't reproduce, I'll close as WORKSFORME and wait till the next time. Closing, since there hasn't been a "next time". Status:
