Recently reinstalled Windows. SD card reader works, but now recognises my 64GB SD card as 32GB (27GB). I have reformatted the card (using another device) as exFAT, FAT32, and NTFS. None of them show correctly. Sometimes when I insert the SD card, Windows instantly says the card needs formatting, but only allows 27.8GB to be formatted.
I have reinstalled Windows before, but have always used the official Lenovo recovery discs. This time I used an official Windows 7 Ultamite disc. Once installed I downloaded all the drivers from the Lenovo web site. Everything works perfectly but the SD reader.
I am 100% positive the SD card reader at one time recognized my 64GB card. I used it for over a year to transfer files directly onto the 64GB SD card.
