USB drive shows only one partition

Just thrown away my hideous BT Home Hub 3 and replaced it with a Netgear D6400, latest firmware installed (V1.0.0.56_1.0.56).  All seems well except for the USB-connected 2TB Western Digital drive I've been using for a number of years (if I recall correctly it worked with my previous Netgear ADSL device too).

 

Simple problem: there are three partitions on the drive but I can only see one.  Wasn't a problem for the crappy BT device.

 

I've seen some posts suggesting it may be a genuine issue with the Netgear devices, ie. there don't appear to be successful resolutions to this missing configuration.

 

Can I configure my way out of this or do I have to combine all of the partitions into one?

 

Thanks,

 

Keith

      Hi,

       

      There's a primary partition and two logical partitions, all formatted as FAT32.

       

      Thanks,

        The only answer I am thinking about is that the device is booting only on one partition and on the primary and do not recognize the logical ones.

        I may be wrong!

  • It's not a boot device, it's only used for storage. I can only see the primary partition through ReadyShare, not the logical ones.

      I know this is not a boot device but the way the unit is booting on the drive it only sees the first partition and blind to the other logical ones.

  • Thanks for your comments and interest, but I'm not sure where this is going: I know it only sees the primary, that's the problem.

    The question is whether more recent Netgear kit can or should recognise multiple partitions on a USB drive? My old ADSL router could (I think it was a DGND3300) and the lousy BT kit could ... why not the D6400 which is way superior in all other respects.

    Thanks.

      Do you have an USB key, make an experiment doing 2 partitons and see if the 2 are recognized or only one?

       

  • That was a really good suggestion. I eventually got a USB thumb drive set up with two partitions and ReadyShare does actually see both: fantastic news!

    I think the two non-primary partitions may be Extended rather than Logical (they're reported as logical by the EaseUS tool I'm using). I may be able to convert from Extended to Logical in which case job done! Let's see.

    Thanks.

        Success!  But I'm not 100% sure why.

         

        Having spent Sunday backing up the three partitions on the USB drive, last night I converted one of the extended partitions to logical in EaseUS Partition Manager and confirmed that the content was as I expected on a desktop.  I then plugged the drive into the D6400, expecting to see the primary and one of the non-primary partitions ... and lo! ... I could see all three.

         

        I'm currently running with an apparent mix of three types of partition but it seems to be quite happy, I have the primary, a logical and the unconverted extended partition.  I don't intend to tinker further, it's working for my purposes.

         

        I reckon this is solved: thanks for your help!
