Title: How to read a RAID1 single drive in Windows after a unit failure
Post by: jose9790 on December 08, 2009, 08:46:54 AM

Bought a new DNS323, pretty cool the device.  My concern is what to do in case the whole unit in the future fails and I need to read my RAID1 drives.  After created the array and copied information, I removed one drive and connected to usb-sata adapter into my laptop.  Installed linux reader and I couldn't see my files.  Tried from Ubuntu Linux, with no success.  I understand the box is running Linux kernel with ext2 as a file system.  Why can't I read these files? or Is there any other alternative to read the RAID1 in case of a unit failure.

Thank you in advance

What version of WIndows?
What firmware in the DNS-323?
What "linux reader"?

Upto firmware 1.07 I was able to read the disks from the DNS-323 on a Windows XP system using the ext2ifs installable file system driver.

Although the firmware release notes for the 1.08 beta do not mention any changes to the ext2 disk formats, I have to assume that something changed as a disk formatted ext2 with the beta firmware is no longer readable using the ext2ifs driver

I see your signature that says RAID 1 is not disk redundancy , don't confuse the two. But if this is true then why is it called RAID ? Which stans for :Redundant Array of Independent Disks

Actually, if you go back and look at his signature, you have misquoted it.  It actually reads:

RAID1 is for disk redundancy - NOT data backup - don't confuse the two.

Hey guys, the version of Windows is Vista and I am using Firmware 1.07.  The Linux Reader's version is from Diskinternal.  I created one private folder for my LAN and the second folder was setup for FTP purposes and assigned to the FTP server.  After the RAID 1 is setup, copy files in it, I shutdown the DNS and remove one drive and connect it to the SATA-USB adapter then the Vista laptop.  Then, I open Linux reader in Windows and I can open the folder assigned to the FTP server but not the private one. I can see the private folder but it can not be opened. I can do that with Linux reader, in Ubuntu, I can't see the folders, just the mounted icon, it has a lock icon on top of the mounted icon and it won't open.

I've never used the Diskinternals Linux Reader - try ext2ifs and see if  it works for you - but be aware that some folks have reported problems using it with Vista.
