    My router sees the usb drive but it just says "not mounted". I can not find any way to mount it either!?!?

    This used to work a month ago but it was not this particular usb drive. The drive I am trying is a standard Verbatim usb drive and it is ntfs-formatted.

    Pressing the green USB symbol only shows an empty box?

    I have restarted the router and the latest firmware.

    Any suggestions on what is wrong?

    Check the system log for any error message. If it's a large drive, it's possible that the filesystem is flagged as dirty, and it's taking a long time running a chkdsk on it. You could try plugging it back on your PC, running chkdsk on it, then plugging it back to the router.

    i am also having problems trying to mount my WD 1T usb disk, above is the system log, any idea how to resolve this? i have formatted the disk to fat32 removing entirely the security virtual drive component.:(

    Did you try my previous suggestion about fixing the filesystem on a PC before plugging it back to the router? Also if it's a portable hard drive, it's possible it's not getting enough power from the USB port to properly power itself - that's a frequent issue when plugging such drives to small devices like routers and media players. You might need to plug an external AC adapter to your hard drive then.

    somehow after formatting my WD a couple of times (eventually back to its NTFS default), and plugging unplugging a blank USD thumdrive to the back of the router (which mounts with zero issue),

    my WD finally mounted! :eek: Thanks RMerlin for the advice

    same issue here

    I am having the same issue with my 2.5 usb enclosure with 64GB SSD. It was working fine. I unplugged it today and tried plugging back in and it no longer mounts in the router. I tried quick formatting it few times and same problem...any advice? I am running the latest version of Merlin's Frimware 3.0.0.4.372.31...

    This is what I see in my logs...I am hoping someone can shine some light on this...

    Hi,

    The USB error -32 is most probably it’s a result of hardware failure rather than a driver or kernel bug. USB has an over-current protection, which gets triggered when power consumption from the port is too high.

    Unplug all USB devices from the router, turn power off, and wait a minute or two. Plug everything back and boot the router freshly.

    Then we will see if the error comes back... :rolleyes:

    With kind regards
    Joe :cool:

    Thanks for your advice Joe. I really appreciate your help. I went ahead and unplugged all usb devices form my router. I then unplugged the power and turned the router back on with power cable out. I saw a quick flash on the LED's which meant the remaining power had drained. I left router in this state for about a minute, plugged in the power and turned the router back on. When it booted back up I tried plugging in my external enclosure with 64GB SSD but the drive is still not being seen by the router. I am using an external power adapter to my enclosure so that my USB port on the router is not underpowered .Strangely my basic 64GB usb stick is working fine on both ports....I am honestly out of ideas here as this enclosure used to work fine few days ago and stopped after a big file transfer. My main concern is to figure out if this is a software or a hardware issue. The same external enclosure is working fine on Windows 7 machine...

    Here is the fresh log output:

    I have the same issue.

    I am using a Crucial 128GB SSD in a NexStar CX USB 3.0 case. The router recognizes the drive but will not mount it. Nothing appears in the logs other than the normal stuff. There isn't even a reference to the USB in the logs even though the router recognizes the drive and states that is not mounted.

    The drive has no content on it, but it has been newly formatted as an NTFS volume and my Win8 computer works with the drive without issue. The router disk utility has also been run on the drive without any errors reported.

    What's up?

    No idea on the SSD, but I can at least confirm that the NeXtar CX enclosure works fine with the router - I have one with a 750 GB in it here which I use for tests.

    Make sure the drive is MBR-partitioned, and has only one partition (multiple partitions can create issues when the router tries to mount them).

    Hi Merlin,

    Thank you for your reply.

    It's good to know that the case is not the issue.

    I am using Win8 to format the drive and I am not sure in Win8 how to determine if the drive is formatted with MBR. There seems to be no option in the Disk Management utility to select either MBR or GPT. There is definitely only one partition on this drive.

    Curiously, when I insert an SD Card or into the SD slot and examine its properties (right click), the dialog box states that it is a removable device. However, using the same technique, the SSD in the NexStar CX case is reported as a Local Disk. Could this be the source of the problem and if so, how do I go about fixing it?

    By default Windows will use MBR, unless dealing with a disk larger than 2 TB.

    A disk in an USB enclosure is not a removable device, unlike an SD card that can be inserted/removed from inside the reader while the card reader remains plugged. So, that's perfectly normal, and has no relation to your problem.

    Most likely it's a compatibility issue with the SSD.

    Hi Merlin,

    Thanks for the explanation.

    I was afraid that might be the case. I have a 1TB WD Passport that works without issue, so all things seem to point the the Crucial SSD. I guess that was a waste of $100 for the SSD and case.

    Do you think I might have better luck with your firmware build?

    Not in this case I'm afraid. The changes I made were mostly related to 3 TB and 4 KB sector size support.

    I remember that another user also had issues getting an SSD to work properly in an enclosure.

    I assume you wanted to use an SSD because of the noise factor (considering a regular HDD would be limited at 12-15 MB/s anyway on this router)?

    Hi Merlin,

    That's what I feared.

    Noise is one factor. Power consumption (trying to make a few green choices), performance (seek time) and MTBF (1.25 million hours) - no moving parts means higher reliability.

    Thanks for your help

    From Bad To Worse

    With my Crucial 128GB SSD drive unable to mount, I figured I would go to the lowest common denominator and use a simple USB flash drive. I acquired a 64GB unit, formatted it and moved 30 GB of music files onto it. The router sees teh device but will not mount it either. It recognizes and mounts my WD Passport and some other flash drives, but not the 64GB flash drive or my 128GB Crucial SSD.

    So far this router has been a very unhappy experience.

    See in the System Log what happens when you plug it in - it might give you a hint at what is wrong.

    Crucial SSD System Log

    Hi Merlin,

    Here is the System Log from the Crucial SSD. Previously, in other attempts to attach the SSD, there was nothing in the System Log. I attempted again this evening and now I have events related to the SSD being captured.

    I'm not sure if this will point out anything that can be remedied, but nonetheless, here it is.
