reception
In 2009, the computer magazine PC-Welt reported frequent crashes of the program when used with the latest beta version of Windows 7 . So the program was not able to access ext3 partitions smoothly. This often resulted in a blue screen . Crashes of this kind can lead to data loss, for example if there is not yet permanently saved data in the main memory . The program could only access ext2 partitions without errors. In 2012 Computerwoche warned that write access to ext3 partitions was “not without risk”. Data could be lost .
Supported functions in detail
The driver officially supports ext2, ext3 and ext4. The developer warns that he could only test the driver on some of the popular platforms and thus cannot rule out data loss and crashes due to possible software conflicts.
