RAW SSD partition - Bad ending head (CHS and LBA don't match)

#1 Post by bobbo » 22 Apr 2016, 19:45

Hi, I think I posted in the wrong section before as my issue is probably a corrupted filesystem. During a partitioning resizing operation on an external SSD (1TB Samsung 850 Pro), one of my partitions, Drive D (on Disk /dev/sdb - 1024 GB / 953 GiB - CHS 124519 255 63, sector size=512), became RAW. I'd like to recover this partition. When I run a partition search on the SSD with TestDisk, I get the message "Warning: Bad ending head (CHS and LBA don't match)" and "The harddisk (1024 GB / 953 GiB) seems too small! (< 2862 GB / 2665 GiB)". I'm not really sure what steps to take next to try to recover the partition. Any help would be much appreciated. Here's the log (the RAW partition I want to recover has a sector size of 1486991360):
