First of all, I don't know if this is the right place to post such a question, but it seemed the most relevant.
Anyway, as a way of introduction, I'm a linux ignorant person, but I appreciate if you can help me regarding this critical issue to me.
I have purchased the Sagate Central NAS drive (3TB) a year ago and for no reason now there is no electric power at all and thus I cannot read anything on the drive at all. Since the data on the NAS drive is very valuable to me, I decided to disassemble the drive and connect it directly to my computer since the drive itself is an ordinary SATA drive.
The problem is I can't seem to read anything on the drive on my Windows 7. I have researched the issue and it seems the problem is that the file system on the drive is ext4 (Not so sure about this since I know nothing about linux and the drive is not recognizable by Windows). I have tried several linux readers including (Paragon ExtFS, DiskInternals, and Ext2explore). The latter two seemed to be able to explore the drive, however, they see it as 4 partitions (a couple 1GB partitions and a couple 20MB ones). There are loads of folders and files. Accordingly, I cannot recover a single file of my own.
I tried to explore another solution and I decided to use Knoppix 7.4.0 live DVD. Again the same problem as the one I faced with the linux readers on Windows 7.
I'm really desperate to recover the data, can you please help. Appreciate it.
P.S. Sorry for the long post but I wanted to provided as much detail as possible.
