Hello, I'm trying to salvage data from a desktop IDE disk which went sour during a Windows XP re-installation on one of its partitions (the rest was Ubunut 8.04 with LVM).
I put that IDE disk into an IDE->USB enclosure and ran ddrescue on it. It complaint a lot but for now I just want to see if I manage to read whatever is possible at the LVM level. "fdisk -l" on the image file complains about not finding geometry and therefore difference in logical/physical partition size in table: Disk sdd: 0 MB, 0 bytes 255 heads, 63 sectors/track, 0 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x00096ee7 Device Boot Start End Blocks Id System sdd2 12030 24190 97683232+ 8e Linux LVM Partition 2 has different physical/logical beginnings (non-Linux?): phys=(1023, 0, 1) logical=(12029, 0, 1) Partition 2 has different physical/logical endings: phys=(1023, 254, 63) logical=(24189, 254, 63) sdd3 24191 24321 1052257+ 83 Linux Partition 3 has different physical/logical beginnings (non-Linux?): phys=(1023, 0, 1) logical=(24190, 0, 1) Partition 3 has different physical/logical endings: phys=(1023, 254, 63) logical=(24320, 254, 63) If I give it a "number of cylinders" it doesn't complain: fdisk -C 24321 -l sdd Disk sdd: 0 MB, 0 bytes 255 heads, 63 sectors/track, 24321 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x00096ee7 Device Boot Start End Blocks Id System sdd2 12030 24190 97683232+ 8e Linux LVM sdd3 24191 24321 1052257+ 83 Linux (I deleted the windows partition on the image file).
