Seagate 4TB repair problem
Posted: 02 Aug 2016, 08:32
Can't repair filesystem and data of Seagate 4TB hard drive ST4000DM000-1F2168
Hard drive installed into Agestar enclosure with USB and Wi-Fi.
Hard drive had 1 partition only. Now I see 3 partitions: 465.75 GB (RAW filesystem), 1582.25 GB and 1678.02 GB testdisk (7.0 and 7.1 versions) recommends use "Intel partition table type" - and find table without data. I start deep search, but read speed of deep search about 6MB/sec (I need about half of year to end this search).
Next time I choose "GPT". Quick search took 30 hours. Logfile attached (testdisk-short-log.7z).
Quick search showed full directory structure, but repaired 2 files only (2 complete files and about 40 broken files) Some records from logfile
