ImageMate All-in-One with Windows 8.1 - cannot assign drive letter

Hello, I have SanDisk ImageMate All-in-One which worked perfectly well with Windows 7. I recently installed Windows 8.1. The external reader is OK with SD cards, but could not recognize my CF card. The card is SanDisk Extreme 32GB (120 MB/s) After reading in multiple forums, I found this page: After successfully applying this updated firmware, not I see the card, but only in the Windows Disk Manager. I cannot access it in the Windows Explorer because the drive has no letter. But when I right-click on the drive and try to assign a letter, I get: “The system cannot find the file specified.” Please help!


Did any final resolution of the issue?

I am also getting exact same issue on Windows7.

I have updated firmware. Only in Windows Disk Manager, drive is visible.

Could not assign letter to it and not visible in My Computer window.


I am just the opposite.

I can not read SD cards.

Windows keeps popping up for

me to format this drive.

Tech support told me this

Note: If you are using Windows 7 or above, please make sure your card is in the reader while it is connected to the computer.

The system now recognizes the image mate but still I can not read SD cards.

All others are fine!

Just wondering what you would do if you

did not have all of the cards supported?

Luckily I did.
