Take hard disk out of external case (if vendor allows it) and use another SATA-USB case which will provide 512 bytes per logical sector (any cheap case should do it unlike special Seagate cases)Īlternatively, you can try to find a program that supports cloning irrespective of source and destination logical sector size ( see link to HDClone in later post)
Take hard disk out of external case (if vendor allows it) and connect hard disk to PC via SATA port (in case of laptop with only one drive you may use SATA port for optical drive) Connect drive via eSATA cable (if external HDD case and PC itself support it) You will either have to find another external drive with the same logical sector size (I'm guessing 512 bytes) or you could try one of the workarounds offered by Paragon : It may be possible to copy one drive to another using the following workarounds: It is not possible to copy one drive to another if logical sector size of targetĭrive differs from logical sector size of source drive. However some external USB boxes (especially if HDD was designed for external connection) provide 4096 bytes per sector for both physical and logical geometry. Info about logical sector size is stored in disk controller and is reported to operating system (OS), determining how OS sees this drive: as 512īytes per sector or as 4K per sector drive.Ĭommon drives have 512 bytes per sector both on physical and logical level, while Advanced Format Drives (AFD) have 4096 (4K) bytes per physical sector but emulate 512 bytes per logical sector.
įrom Paragon kb : A hard disk (HDD) has physical sector size determined by its geometry and logical disc sector size. That is because data integrity usually cannot be ensured between different logical sector drives. It is not possible to copy one to another if logical sector size of target drive differs from logical sector size of source drive. A sector by sector clone means that even blank sectors with no information will be cloned.
