Have just received a customer's ASUS laptop with windows 7 Pro installed.
The customer has been noticing since June/ July that it seems that files and folders have been disappearing. In some cases, he can see the files or folders but, when he goes to access, gets the message, for example: 'E:\business\EMC Global 2011-2012 is not accessible. The file or directory is corrupted and unreadable.'
I have run NOD32/ MBAM scans on the machine in case it is related to malicious content, but can only find adware associated with downloaded programs the customer has been using for ages (1+yrs), so am not too worries about that.
Thinking that it was maybe Windows that was not seeing what was otherwise there (and to generally be thorough), I ran an Acronis backup and viewed the contents on my Windows 7 Pro office PC - the files/ folders in question were still not there.
I have also run checkdisk on the primary C: partition and the subsequent e: logical partition and all results indicate no issues with the drive. The HDD, from memory, was a replacement 6-12 months ago and is a Seagate 500GB 2.5" HDD.
I have also run GetDataBack for NTFS as Administrator and, although I didn't perform the super-indepth scan that takes many, many hours to complete, the initial scans show nothing more than I can already see through Windows.
The information being 'lost' in critic business information and is very important for the customer. Of course, as would be the case, he has not been backing up for the last few months and has not accepted my advise to use an automated backup program like Acronis - perhaps this is the wake-up call?!
