My daughter is away at college and uses a Lenovo laptop running Windows 7. When the PC has problems I try to fix them by accessing it via LogMeIn. Yesterday she reported that a bunch of her files are missing. She is right. A few days ago (5/27) something happened that caused installed programs and all of her files older than 5/27 (back to some time in 2011) to disappear. Hundreds of gigabytes of data disappeared. The windows logs also skips back to 2011. At first I thought of a virus that hides files. But Security Essentials and Malwarebytes scans show nothing. Windows is already set to show hidden files. Chkdsk shows nothing. SFC shows nothing. Recycle bin is empty. I thought maybe the hard drive is failing. But a usb flash drive that was always plugged in and used for simple backups suffered the same data loss. It would be unusual for two pieces of totally different hardware to fail the same way at the same time. Windows Restore shows that several restore points were created over the past couple of days, some for "critical updates." I tried restoring to the oldest restore point, but the files and programs didn't return.
Using Recuva I was able to restore some files. But I don't know what caused the problem in the first place. Any ideas? I am stumped.
