copied all my files to 4T drive and then erased it with disk utility by mistake (2 my book drives connected 1-2T and 14T and the 4T only reading 2T so erased wrong drive). I want to recover my data. Now the drive is unreadable but shows up with Stellar Phoenix Mac Recovery software but just can’t read data. The drive shows that the formatting was changed to HFS+ when it had been fat32. Any ideas?
