NAS200 1.5 TB Drive - Formatting?

    Hi,

    I have just bought a 1.5TB USB drive to connect to the NAS200, but when I do, it can read the data, but it cant write (because it was preformatted NTFS).

    The strange thing is though that it comes up with an error when I try reformatting it from the web admin page so I can't even reformat it.

    Can anybody help?


    Also, my firmware is V3.4R62 and despite endless searches on linksys, here, and google I cannot find a newer version. Is there one?


    Cheers,
    Steve

    Nas200

    The current firmware that i am running is v3.4r75

    as far as the 1.5tb drive... That i can't help you with.. But i
    will do some research for you and repost updates

    I do believe that the largest drive you can currently use with a NAS200 is 1 terabyte. I will have to dig through the source again and confirm, but I seem to remember a reference to a max drive size in there.

    Would it help if I partitioned the USB drive into 2x 750GB partitions? or is it actually the drive that it has problems with?

    Another size related problem I have come across is that the NAS200 doesn't have enough memory resources to do a file system repair on 500Gb disks. If you get a filesystem corruption on a large partition there is no way to fix it without pulling the drive and connecting it to a real PC - which really sucks when my NAS200 is remotely located over 200 miles away.

    Is this with the journalled or non-journalled filesystem???

    With the XFS filesystem.

    I was also planning to upgrade to 2x 1.5TB drives (internal). I'd like to know if somebody has experience with this. Is it true that the largest supported drive is 1TB?

    Some formatting stats

    I just installed a new 1TB Western Digital Caviar Green in my NAS200. These aren't the fastest around but that doesn't really matter with the NAS200 anyway...

    I started formatting it from the Web GUI but that doesn't really tell me anything so I decided to kill the process and redo it by hand so I could see what's going on:

    Code:
    $ mke2fs -m 1 /dev/sdb1
    mke2fs 1.40.2 (12-Jul-2007)
    Filesystem label=
    OS type: Linux
    Block size=4096 (log=2)
    Fragment size=4096 (log=2)
    122060800 inodes, 244099634 blocks
    2440996 blocks (1.00%) reserved for the super user
    First data block=0
    Maximum filesystem blocks=0
    7450 block groups
    32768 blocks per group, 32768 fragments per group
    16384 inodes per group
    Superblock backups stored on blocks:
            32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632, 2654208,
            4096000, 7962624, 11239424, 20480000, 23887872, 71663616, 78675968,
            102400000, 214990848
    
    Writing inode tables:  911/7450
    
    It looks like it's doing about 1.8 inode tables per second (measured and averaged over a 10 sec period), so it looks like the ext2 format is going to take a little over an hour (7450/1.8 = 4139 seconds, 4139/60 = 69 minutes)

    A format in journaled mode takes mere minutes...

    I'm using journaled mode, because I'm mostly interested in data availability and don't care that much about the speed. This is what the NAS200 does perfectly in my opinion. No problems at all.
    If 1TB drives are supported I think about putting two of them in the NAS200 and format in RAID1 with journaling filesystem. But 1.5TB would be better...

    I don't mind if the NAS200 has not enough memory to repair the filesystem, because if the filesystem might fail it would indicate a serous problem. In that case I would connect the disk to a pc to save my data anyway.

    Linksys says :
    NAS200 supports following File System operation through USB ports:

    *FAT: Read and Write
    *FAT32: Read and Write
    *NTFS: Read Only

    I just bought an external 1.5 TB USB hdd and plugged it in the NAS200. I must say I noticed a difference in the performance of the device. More slow response that is. I am not 100% sure the addition of the external hdd made it slower. I'll test it more and get back.

    Is there a way to attach the usb hdd containing just one big 1.5 TB partition and still be able to read and write. I was just a click away, sort of speak, to format the partition to ext2 but then saw the above from Linksys and had second thoughts about solving my problem.

    Has any of you ladies and gentlemen an answer to the above?

    Your only option is to format the drive as FAT32. Theoretically FAT32 supports volumes up to 8TB, but I'm not sure Windows XP / Vista will allow you to. Windows might be limited to 32GB. You could connect the drive to your PC and try to format the drive with a bootable partition utility (like parted) or a live CD from a linux distribution.

    Or you might try to build your own USB ext2 support for NAS200...

    Good luck.

    Thanks for your answer Johannes. Windows wont let you format the drive to FAT32. Partition magic as well. The only option I guess is to format it to EXT2 but linksys says that:
    I guess I'll stick to NTFS so that I can use the external drive not only with NAS but with other computers as well via USB.

    The menus get to be horrendously slow after the device has been running for a few days.
    Perhaps most importantly, the main function of this device being RAID capability, when building a RAID 1 array the device never actually performs a full synchronization between the drives. I had two identical new drives in the unit, set them for RAID 1 and formatted them. Without copying any data to the drives, it began syncing them. (Why it would need to is beyond me.) It moved at a speed of about 1% every two hours and would only get to about 15% before it began over. The drives never spun down and I left them for 12 straight days.

    This was all with the latest firmware that was released in June '08. It looks like Linksys is done with support for this unit as there has been nothing in over 6 months. Even if Linksys releases a much better firmware version, the chipset in the unit simply isn't capable of higher throughput -- it is maxed out right now.

    NS200

    Using an external USB drive will only permit read-only access.....
    I ran into much the same problems after buying my unit just prior to Christmas, wish I had of known this was such a dog before I bought it.....

    Would of been cheaper and faster to resurrect and older machine for a fileserver.....

    Bottom line.. The NS200 sucks.....

    If the USB drive is NTFS formatted, yes. Unfortunately the NAS200 doesn't run NTFS3. If the USB drive is FAT or FAT32 formatted, you can read and write just fine (but everyone has access to it).

    I thought the same thing when I got mine, but I was happy to discover that it's so easy to hack. Basically it's a headless 486 PC (albeit a slow one).

    True, but less fun and probably not such a pretty box :wink:

    Of course you can always get a Pico motherboard and do a brain transplant.

    Yes, you are correct, I stand corrected about the NTFS USB....It is easy to hack, makes a fun toy, but far form a serious network device. I was looking for a storage solution for my home office. :)
