I've formatted an SD card from ext3 to NTFS using Acronis. But after that any memory card stopped to mount in system.

I have reinstalled card reader drivers but nothing. I think it's win7 problem, because memory cards and card reader are work well.

Do you need any information about the problem?

laptop: Lenovo e320 1298-rs7.

Does it work successfuly If you use a different SD card in the reader? If so then you do not have card reader driver problems. Instead something is wrong with the SD card or the formatting on it. Try wiping it and reformatting with diskpart. ([start] [run] 'diskpart` list disk select disk X. wipe). – Hennes Jun 16 '13 at 12:21
Anyone sd card doesn't work in card reader in windows. When I type 'list disk' i see sd card in the list. – Alex Rezistorman Jun 16 '13 at 17:20
@Hennes: I think you meant clean instead of wipe. – Karan Jun 17 '13 at 17:08
Oops. Correct. The clean command is needed to wipe the MBR/GPT info. – Hennes Jun 17 '13 at 17:10

Start → My computer(right click) → Manage → Storage. Set up letter for defective disk. Reboot. That's all.
