SD Card not being read by Windows 10: "Please insert a disk into Removable Disk (L:)" ?

[Dinarius]

Windows 10 Pro x64

I have two SD cards containing video files.

One is 16Gb and one is 128Gb.

When I inserted the 16Gb card, the video files were transferred from the card reader to the computer's HD, although very slowly - there were a few pauses during the transfer.

Now, I've just tried the 128Gb card. When I insert it into the card reader, instead of it appearing on the left in File Explorer, another window opens with a spinning wheel and the message: "Please insert a disk into Removable Disk (L)."

AFAIK, the card reader is perfect. Although I normally only use compact flash cards with it for stills photography. (I've just transferred two compact flash cards of still images from the same shoot, with no problem.)

The video on the 128Gb SD card plays perfectly from within the camera, so I don't think the card is the problem.

How can I make the files transfer to the computer?

Thanks.

Buy a new card reader that supports 128GB cards. Unlike CompactFlash cards which have all of the electronics inside the card (which is why they are IDE devices--they have Integrated Drive Electronics), SD cards require the reader's firmware to understand and translate the structure of the card.

Back when SD readers were new and expensive it was sometimes possible to get a firmware update to support newer high capacity cards as they came out. Not so much any more.

Ah!

That might explain it.

The card reader is 11 years old!

The only SD cards I've been using to date were up to 8Gb, and only very rarely. 99% of the time, I use CF cards and have had no problem with those on this reader.

Thanks.

I think you have same problem as phones have. they work UP TO certain size.
SDXC cards will work in SDHC compatible readers (not SD readers) if the computer OS supports exFAT.
see if drivers did not add SDXC support

LOL yep, in 2006 the large SD cards were 4GB and SDHC just came out, so it's likely your reader can use up to 32GB cards.

OTOH you could plug a 512GB CompactFlash card right in and it would work fine. Which also means that if you were attached to that old cardreader because it's convenient on the front panel or in a laptop or monitor, you could get a SD to CompactFlash adapter that understands 128GB cards (generally marked as SDXC) to plug the SD card right into the CF slot. This has the added advantage of letting you use the SD card in CF cameras too.

Of course a new USB 3.0 cardreader would be much faster, but then you'd also need a USB 3.0 adapter.

Bought one of these

Loaded the SD card video files in a blink!

Thanks all for the help.

Much appreciated.
