Netgear sc101 NAS - What file system?

[zed]

Hi All,

I have a working IDE hard disk from a netgear sc101 NAS (networked external hard drive).

I have examined the disk using X-Ways, R-Studio, UFS Explorer, GetDataBack, File Scavenger, Encase, FTK and almost all other commercially available data recovery tools - no disk can read the file system on this disk.

This is the device:

I contacted netgear, no help at all. I purchased an identical unit, put the disk in that - no difference, the unit seems to think there is no disk in the unit, i.e cannot see the disk is even formatted.

There is data ont he disk that can be seen by a hex editor.

Has anybody found any way to recover the data from a disk like this?
Any suggestions would be most greatly apreciated.

P.S Not even a RAW recovery works! 0 files found...due to the way the file system works.
*fingers crossed*

Hi!

Pleasy more details:

Is only one hd IDE? Or they are two?

How it is making the access? through door IDE of the PC?

[coolmac]

it is a RAID in fact,i guess,did you read its Specifications?
http://www.netgear.com/Products/Storage ... ifications
Supported Hard Drives

Two 3.5” internal ATA6 or above IDE hard drives
so you have to image them respectively,and then Create virtual volume sets or RAIDs with R-studio ...,btw,how did you connect it with you DR platform physically?

There is only 1 IDE disk in the enclosure. It's not part of a RAID as there was only 1 disk.

I am trying to access it now using an IDE cable on a PC. The file system is one which is not recognised by any data recovery or computer forensic program.

I am trying to find some way to recover the data and save it to a NTFS formatted disk. Anybody had experience with this?

Hi,

The problem may have been caused by an unsolicited firmware upgrade.

There are threads on the Netgear forum that might help you to repair the partition.........

Hi, I had a similar problem with a Quantum Snap Server.

No s/w could see any decent data on the drive at all.

The unit had two problems, the box was bad and also sector 0 of the HDD was bad.

Bought new box and ran HDD regen on the drive (after imaging it first, for backup, just in case!)

Put the fixed drive in the new box and connected up, it insisted on running a routine repair on the HDD, but after that data was back 100%!!

Hope it helps.

Thanks for your help, gave up on this one. Client was not prepared to pay for the time to research this one.

The file system is ZFS, and stands for Zenith File System. Thats about as far as my research went, could not do a thing with them. Hopefully somebody will find a solution soon!

Netgear says the file system used by the SC101 is the SANS File System (SFS):

I wonder if Netgear gets it from DataPlow, who also does a SANS File system (even though Netgear is not listed under Dataplow's partners page).

There's a good related post at

As you can tell, I'm trying to get data off one of my SC101 drives.
