If you use SD or CF cards and have (against the advice) upgraded to Windows 10 you should read this:
Windows 10 corrupting audio files
Now, it’s not quite as bad as that headline might suggest as it only appears to be affecting some users if all of the following are true:
– you have WAV files on an SD or CF card (e.g. as used in portable recorders)
– the card is formatted as FAT32
– you have upgraded to Windows 10 (and not clean-installed)
– the card reader is connected via USB (and some “internal” readers are connected internally via USB)
These are the links to the Microsoft Community forums which describe the issue:
Windows 10 corrupts files without warning on SD & CF memory cards (FAT32)
… and the longer, but harder to read one:
transferring .wav audio files
The scary bit is that, according to users who have experienced this issue, all that is required is for the card to be put into the card reader for the corruption to occur, i.e. you don’t even have to have tried to read from the card.
So for the moment the advice (apart from, “don’t upgrade to Windows 10 yet”) to write-protect your cards before putting them in a Windows 10 machine!
