So, I have another unlucky Seagate... 500GB SD15. It was detected by the bios, but not in windows. It was not LBA 0 since, for example, testdisk doesn't see it at all and any other recovery software the same. It was something in between the bsy and the the lba 0. I decided to attempt a bsy solution from avico and now it is detected by the bios and by windows. The last cmd (m0,2,2,0,0,0,0,22) exited with 1 partition formatted. BUT! They are 2! The user, in fact, formatted it in 2 dynamic partitions. I made a full dd image and inspected it with recovery softwares. Only the first one, 100GB is visible and I can recovery everything inside. The second partition is something like blank. Nothing inside. No file system, no files, nothing. Photorec doesn't find any files. Not even 1 small file. I tried another LBA 0 fix. The same: just one partition formatted and again I can see everything inside the first one, nothing on the second one. Any idea? The files I need to recovery are, obviously, into the second partition...
