Hi, does anyone knows if dd_rescue works to rescue an NTFS partition? Thanks in advance, -- --------------------------------------------------- Thiago Santos Faria Xavier Teixeira ---------------------------------------------------
Based on the description, which indicates it works like 'dd', except it will retry on failure, skipping failed sectors, the answer is 'yes'.
This is because dd and, by extension, dd_rescue, do byte for byte copies of a 'raw' device. This means there are no dependencies on filesystem types, data content, partition type, etc. In fact, you could use either of these on the whole device (hda rather than hda#) and it would copy MBR, partition table, and partitions (regardless of FS type) faithfully. You could then put this on a disk of equal or greater size, being aware that if the destination is larger, you *will* lose that extra space because the dd copies the original disk geometry info to the new disk.
But, qualify this with, if it skips a sector, you have no idea if the sector is used or not, if it is used, if it's in a system critical file or not, and so on. You will have to run the appropriate filesystem repair utility (fsck, checkdisk, ...) to try to fix things so files at least are readable. But the data in those missing sectors is lost, period.
