Hi, for some time, I have a problem with access to directories of Lacie
Access the administration pages is available but when I try access to disk its tells me that "An unknowned disk has been detected. The file system is not supported or there is no partition on the disk"
Can´t access to myshare or openshare. Not exist
What can happen?
Nor let me reformat. The option is disabled

Thanks in advance

Hello again, I have decided to remove the hard drive and mount it on a linux system through sata.
The system detects the disk and identified as 1 TB hard drive but when trying to mount it gives me an error "structure Needs cleaning" and does not allow me mount it.
From what I've read the disk has several partitions, and I think that gives problems is the partition 2, which is used for storage. If I could reformat that partition could recover the system.
Can someone help?

Sorry for my English

You could try xfs_repair on that partition.

Open a terminal (command prompt) and type
Code:
cat /proc/partitions
Find your partition. The sizes a in kB. Assuming the partition is sdb2, and that you are using Ubuntu, you can execute
Code:
sudo xfs_repair /dev/sdb2

Hi! Thanks for your response. Works hard drive again!!!

This is what I've done:

As you said I open the console and type

cat / proc / partitions
them
xfs_repair sudo / dev/sdb2

The system starts to Scan and after few minutes finish.

I disconnected the Harddisk to the PC and put it back into NAS box.
Open the NAS configuration Web And voila!!! the NAS allow me to format the hard disk.
Once formatted and myshare & OpenShare folders are accessible again

Thank you very much

Sorry, I can´t help you.
All I did was follow the steps I have described above and it worked.
Maybe someone with more knowledge of Linux can help.

I *think* that means that the filesystem is seriously damaged.
Does the disk contain data which has to be recovered? If not, you could format it:
Code:
sudo mke2fs -j /dev/sdb2
(This will format the disk ext3, not xfs. Lacie disks seem to have troubles with xfs partitions from newer Linux systems)

My networkspace has suddenly stopped working and going in to it's config pages I also get the "An unknowned disk has been detected. The file system is not supported or there is no partition on the disk." message.

Unfortunately I need to recover the data - has anyone got any ideas?

Thanks in advance folks.

Depends on the nature of your data. If that is mainly photo's and movies, get the disk out of it's case, and connect it to a PC. (Directly or using an USB-SATA converter). Say 'no' to any helpful hints of your operating system. Then use PhotoRec to recover your files.
When the data consists of flat textfiles, there is no other option than searching the disk for keywords, using a disk editor, and manually copying the interesting sectors.
