After a power outage attached hard drives are read only

    After a power outage, my nslu2 attached hard drives are read only. I can see all data perfectly, and the nslu2 administrative web pages seems to act normally and without error, but when I try to write data to the hard drive, it is read only.

    In searching the web, I have seen reference to others with this issue, most saying that you have to connect the drives to a linux pc and run a file check utility from there to get it working, but that seems extraordinarily difficult. Is there not some way to fix this problem simply through the NSLU2 admin?

    I also saw reference to someone who fixed it by starting a scandisk through the nslu2 admin and then stopping it midway, but when I tried that, the system told me that the drive could not be accessed during a scandisk so the operation couldn't be stopped.

    Any help would be appreciated. Thanks

    I had some EXT3 corruption after I had a power flicker. Unfortunately, I could not access my data at all using the NSLU2... it said the disks were not formatted. So I used a Linux PC to take the files off, then used the NSLU2 to reformat the drives. The disks were working again after the format, so I moved the data back. I currently have my NSLU2 and both drives on a UPS.

    If I were you, I'd take the data off of the disks and then use the NSLU2 to reformat them.

    I have had the exact same experience. After a power failure, the drive on the NSLU2 was read-only to all users.

    Linksys advised that I upgrade the firmware. I did end up going to a different version than they recommended and that fixed the problem.

    Now, I have a similar problem, but only worse. Now it appears that the usernames/passwords that are on the drive have gotten corrupt. No one can connect to the shares, and worse yet, no one can connect as administrator either. If we remove the drive, then we can connect as admin, but that doesn't do much good.

    It appears that power failures can cause corruption in the file structure of the drives, so I would agree that a UPS is probably a must.
