I recently purchased a USB cable for my N810 so I could transfer music and pictures to the tablet. When I plug the device into the USB port, there is no recognition of it on my computer. Could the cable be bad? Or maybe it isn't the right cable, but it fits. I was given this tablet from my sister who knows nothing about it, and it didn't come with anything except a charger. Please help me out if you can! Thanks

The N810 has a micro USB socket, so any USB data lead with a Micro USB connector should work fine.
Some questions...

1. Go into Settings, Control Panel Memory, Virtual tab, and check to see if you have "Extend virtual Memory" ticked.

2. Do you have a mini-SD card (or a microSD in a mini-SD adaptor) in the slot (known as the external slot) under the stand?

If the answer to the first question is yes, then you will not see the 2GB which is fitted internally to the N810, as it is in use by the tablet, and will not be available as a drive over USB. If you want to see that drive over USB, then remove the tick and reboot the N810, and then reconnect to USB

Obviously if you do not have a card in the external slot, then you will not see that. If you have then the best thing may be to re-format it, after backing up any data which you want to keep. Again this can be done from the "memory" dialog in Control Panel.

I actually find that the best and quickest way to transfer a fair bit of data to the removable (external) card is to remove it from the N810, and plug it into an SD card reader, and pop it back in once the data is transfered.

I do not have a mini-SD card in the device and I just extended the virtual memory. I re-booted the tablet, hooked up the Micro USB and my pc still isn't even recognizing it! I have went to Start--My Computer--And all that is listed is the C and D drives, like nothing is even plugged into the USB drive!! Is getting a mini card my best option??

If you turn off the virtual memory, then the 2g internal card will be recognised when you plug USB in.

Otherwise get a microsd card and a miniSD adaptor. The local computer shops near me sell MicroSd card which as well as the card have a miniSD, and a full size SD adaptor. The N810 will take any size up to 32GB quite happily. I've used 8, 16 and 32 in mine with a miniSD adaptor with no issues

I recommend NOT using virtual memory with the N810. I'd turn it back off; it tends to corrupt the internal 2Gig memory.

If you are worried about internal mmc wearing, move the swap file to the external mmc, or use ramzswap (look for ramzez). With only 128 MB RAM, a swap file or partition is more a need than an option.

Really? I've not experienced that.

Thanks all of you, but I am still unable to get my pc to even recognize that the 810 is even plugged in. Every other time I plug something into the USB port, an icon pops up on the taskbar with this tablet nothing ever happens. I'm thinking the cable might be bad, idk.... I just bought it..It says Nokia Micro USB data cable Model: CA-101D, compatible with N810?? wth???
