yesterday i was working on my Seagate external HDD copying a large file, suddenly i got the electricity off and when i turned the computer back on again, when i tried to open it back again, it asks me for format..i close that and i try to open it from my computer and i get this msg " disk structure is corrupted and unreadable " i see the drive as a RAW disk
i tried chkdsk with all the possibilities, i got "Corrupt master file table. Windows will attempt to recover" and then it says it was unable to fix that
i tried fix MFT from test disk, i got msg says the mirror MFT is corrupted also
ad right now am trying the deep search

am wondering about these wornings
please help me to get back my external running and don't tell me i can't retrieve the data, it's all a project and studies from a year and a half and i don't want to lose it
