NASLite Network Attached Storage

My power went out last night - and so did my nas. I powered it back up this morning and now I only see 2 of my disks (out of 3). When I look from telnet the 3rd disk is there and is ready to be formatted. When I look from http - "Disk-3 is installed and can be configured for use with NASLite-SMBG."

Here is what it says on the disk-3 page:

Any help here would be greatly appreciated.

On rare occasion, an IDE disk may be damaged in the event of a power failure. This is especially true if the power outage is not clean where power just goes out, but rather long with a brownout period during which the machine can get damaged. In your case, the disk appears to be ok except, according to the log you provided, the partition table appears to be damaged.

You may be able to recover the content in full by running fdisk. Do not make any changes to the partition table and just enter w to write the tables back to the disk.

Do that in Linux and not windows or DOS. Any live CD should do, Knoppix probably being the most popular.

If this does not correct the partition table flaw, then there is a possibility of data loss. Data recovery tools will be necessary for extraction.

Thank you Tony.

Would you mind giving me the exact command - as I am not very familiar with Linux.

Disk-3 is your secondary master. At the shell prompt just run "fdisk /dev/hdc". Use the "w" option to write the partition table back to the drive.

You can also use "cfdisk /dev/hdc" which will provide you with a full-screen curses display, but fdisk is probably safer.

If you have questions about fdisk usege, "man fdisk" will give you a good start.

hope that helps.
