Hi, Thanks for your quick reply. There's no rush with this problem. I need the data at some point but not immediately. First off, i was wrong about the lseek-offset. The correct offset it tries to seek to is "4503599627370496" (decimal) or 0x10000000000000 (i was missing a few "0"'s) The partition is of course not of *THAT* size. I tried serveral partition sizes (the harddisk itself is bigger). I tried both sizes ntfsclone reported (628592312320 bytes and 628592315904 bytes) as well as 700 GiB and a few other. The "Variant 1" always fails with the lseek-problem. Variant 1 strace log file: http://www.sbsw.net/ntfsclone.strace.gz "Variant 2" always says "write: no space left on device" (which is obvious if it tries to write up to 4503599627370496 bytes) also with various partition sizes. It also continues to count over 100%. For example if i set the partition size to 700 GB it will count up to arround 118% (just an example). Then i tried "Variant 3": ntfsclone -r backup.ntfs -O /mnt/data/file.img The /mnt/data filesystem had arround 3,8 TiB space free. And ntfsclone aborted (?) after hours (exact message unknown). The file.img it created was arround 3.8 TB. It wrote as much as there was space to write to. (like Variant 2) - Simon ------------------------------------------------------------------------------ Don't let slow site performance ruin your business.
