My SD card was working perfectly in my LG Optimus L90 yesterday and connected to my HP Windows 7 laptop without any issues just 2–3 days ago. However, today, when I tried accessing media on my phone, it showed nothing. I checked the phone settings, and it stated that no memory card was detected. To rule out a phone issue, I tested SD cards from three friends, and all of them worked fine on my phone, so the phone itself isn’t the problem.
Next, I inserted my SD card into my laptop, but it didn’t recognize it either. In contrast, my roommate’s memory card was instantly detected and opened on the same laptop. I also tried using the Device Manager, but my SD card wasn’t listed, nor did ZAR recovery software detect it.
What steps can I take to recover the data, particularly a crucial video I need by next week?
