I have a dual boot system consisting of Arch Linux and Windows 7, with a shared partition to access files from both systems. Until a couple of weeks ago, I was predominantly using the Windows OS as I needed Windows only programs daily for my work. Now however, I do not require those programs and so have switched to using Linux virtually all the time.
I have used Windows twice in the last two days, and each time I booted into Windows, it ran the chdsk utility and subsequently deleted a whole lot of files from the shared partition. I didn't notice it the first time, and then found a whole lot of files were missing, but I just booted into Windows this morning and it happened again. This time I watched the output and it showed a whole lot of files being deleted. There were some new ones that I had only just created in Linux, but also older ones that I had made in Windows.
This wasn't a problem (it didn't happen) when I was predominantly using Windows. I could use Linux for a bit, then restart in Windows and it would be fine. Now that I am using Linux more though, this has started happening.
When it happened the first time I wondered if I might have a virus and so downloaded Avast for Linux and scanned the partitions accessed by Windows but that didn't find anything.
Any ideas on what might be causing it?
