I'm recovering data from NTFS partitions in raw mode. Is it normal that it takes out extremely slowly? Within five hours it has been scaned only 20M sectors (whole drive 3900 M sectors) The HDD is ok. |

agreed, drive has some issue e.g bad sectors, check s.m.a.r.t status |

There is no error in the SMART. Binary copy speed is about 15-35 MB/s into the file. Also to slow. |

I lost my patience. After 2 days scanned Data Extractor scanned only 600M sectors. For comparison PhotoRec in 8 hours passed 55% of the disk i.e. about 1 TB. Where is the problem with the DE? |

PhotoRec is running at 38 MB/s whereas DE is achieving less than 2 MB/s. Is it possible that DE is stuck in PIO mode? |
