![]() ![]() And I'm not really sure how to interpret that. The closest I've come is Gsmart Control, which reports 512 logical / 4096 physical for the drive while it's in the USB enclosure. What I'd like to know if there's a utility to definitively tell me how an external drive is presented to Windows. I'm resigned to playing it safe, buying a new 6TB external USB drive and copying over everything from within testdisk. I've done several successful limited test copies to disk from testdisk, and the files (mostly photos) appear to be correct, whether the sector size is set to 512 or 4096. I don't want to risk damaging the beginning of the single NTFS partition that occupies the entire disk. ![]() Crystal Disk Info does not show the sector size when the disk is in the enclosure. The partition remains readable, but I'm reluctant to write out the new partition table with the 4096 geometry without knowing whether the enclosure is actually presenting the drive with a 4096 sector size. I've tried changing the disk geometry to a 4096 sector size, which reduces both the starting sector and total number of sectors, obviously. However, after putting the drive into the enclosure and deliberately plugging it inUAto a USB 2.0 port (to avoid possible problems with UASP optimization on a 3.0 port), it still comes up the the sector size error message. Use 'recover partition' to recover files from deleted Seagate hard disk partition,lost Seagate hard drive partition,changed Seagate hard drive ,damaged Seagate hard drive partition.And if the size or position of Seagate hard drive partition is changed by format,It can not recover with 'unformat'so you can use 'recover partition'mode. So I bought a USB 3.0 external enclosure (Orico), thinking that it would translate the 512e drive into a 4096 drive like the Seagate enclosure did. Crystal Disk Info confirmed that the sector size of the SATA disk is 512. Further analysis by testdisk showed the common error of mismatched sector sizes: 4096 in NTFS, 512 for the hard disk (HD). I wrote the partion table to the disk and rebooted, but Win10 did not regconize the partition table. When I plugged the GPT layout drive into a SATA port, testdisk detected the correct partition format immediately. The physical drive still works, but this was one of those enclosures that translated 512e to 4096 sector sizes. I'm helping a friend recover the contents of a 4TB Seagate Desktop Expansion disk whose enclosure pcb failed. ![]()
