I have a wd sharespace 2tb unit. It was configured as mirrored so each 1tb disk should be identical. (?) The raid function on the wds appears to have failed. I can no longer access any shares on the wds, it has been working just fine for a year. However, the web interface works fine and reports that both the disks are healthy. However the following error message appears at the bottom of each screen in the web interface:
“Warning: Unknown(): write wrote less bytes than requested in Unknown on line 0 Warning: Unknown():
Failed to write session data (files). Please verify that the current setting of session.save_path is correct (/tmp) in Unknown on line 0”
Yes, it doesn’t look good.
As we do not have a current backup of the wds, I would like to access the data by some other method, do a backup then re-initialise the wds and setup raid again.
I have therefore removed one of the disks, put it into a usb-sata enclosure and connected the disk to another pc via usb. Win XP can see the drive and reports it as healthy. It actually sees 4 partitions, one of which is ~ 930gb and presumably holds my data. However, XP doesn’t assign, and won’t let me assign, a drive letter to any of the partitions so i cannot read from them in order to do a backup. All right click options in XP’s disk management are disabled except “delete partition” and “help” neither of which are much good to me.
I have also tried to use GetDataBack for NTFS, a nice tool that has saved my bacon before. If i run it over the smaller partitions, it can’t find any file systems to recover. I have just initiated it to run over the 930gb partition and it says it will take 16 hours to run (with no idea whether it will find my data or not?).
So, i’m looking for URGENT help please in how i might best recover data from the disk and back it up before inserting it back into the wds.
Sorry for the long post.
