Recovering old Readynas (Rnd4000-100NAS V1). Power supply failed, drives all check out (3x1T), imaged the drives as planning to use the three drives in a new ReadyNas. Installed a demo r-studio on Windows to do the above and have the three images on a 4T data drive.
The drive layouts clearly indicate V1 Rnd4000 in a raid4 configuration with drives 1&3 showing partions and drive 2 showing no partitions (per research here and elsewhere. During this Raid4 investigation, I tried scanning the individual and group of drives using block volume autodetect which clearly did not return the data - but only the system positions (help files, Sql an etc). Used a variety of other data/nas tools to see if they could see into the data partition - with many showing text, images, movies and music. Most show as recoverable but clearly a number (5%?) Are striped as only the initial part of the file is available.
Tried using Reclaime to get parameters but it kept giving a maximum block size reached error message. Tried some other NAS recovery tools to see what if any parameters they could come up with. One came up with left-symmetric, 512 byte block and simple image of data layout that matched what I had expected to see fur this V1 Nas.
I put the parameters in r-studio and ran a scan - low and behold - it came up with the same general visual results in the scan-information window. Opening a couple of the individual scan panes - I see lists of files add I would expect. However, when I go to open the drive by file type - I get a message "the selected system does not contain any supported file system or the file system is corrupted. Select the Scan command. . . "
What am I missing?
- incorrect parameters? Does someone have better fit this old nas?
- I suspect the file system is inside the sql database, but shouldn't r-studio have done ability to recover the file - when it can be seen in the scan-information individual pane?
