I found that every time I restart the mac nothing happened, meanwhile, if I completely stop the mac, wait some minutes and restart the system 9/10 times, the drive come on erased and with an EFI partition also mounted on my desktop. I left one of my two firewire HD as “target practice” and I started to do several try. Sorry for the delay in answering, but you will easly understand I was in trouble with attempts on recovering files. I have, of course, another back up of the raw files, but I lost all the worked ones, the libraries, the completed jobs and so on.Īnyone encountered this problem? Anyone has a suggestion on what can be happened (because now, I did not trust the raid 1 anymore!).Īnyone has a suggestion on how I can recover my TOC data file (I hope the files are still there and only the table was erased). I’m astonished, all my data files are gone.

The name of the disks was “My Studio” as when they come out from the factory. I immediately figured out that something was running bad both disk were completely erased. I went to bed leaving the mac on because it had to finish the upload on my dropbox and this morning I turned everything off without payng attention if something changed in my disk actually… but when I restarted the mac, the OS asked me if I want to use the firewire disks for the time machine!!! I worked, I used my ext drives (in which I store my data files - in the raid 1 one) and nothing strange happened. I also reinstalled the WD raid control (for the My Studio II) and it looks like that everything was correctly managed. I don’t know if it’s important, but yesterday I made an upgrade to my mac with an SSD installed in the super drive sata slot with a clean install of the High Sierra OS.Īs soon I reconnected all my ext drives, everything runs fine. I have an imac 27” late 2009 (i7 - 16Gb Ram) with High Sierra installed and two External HD Western digital firewire (one is a my studio 1TB and the other isa a My Studio II 2+2Tb in Raid 1 configuration).
