2.1 Can Data Compass recover firmware corruption?
Data Compass is intended for data recovery only and can't recover firmware-related problem. For firmware problem, you need to use HD Doctor.
2.2 What's the function of Data Compass?
Data Compass is a data recovery tool used to extract data on HDD, especially those drives with severe bad sectors. With advanced technology, Data Compass is a powerful tool to retrieve your data.
2.3 What's the function of Shadow disk? When should I use Shadow disk?
Shadow disk is the essential technology of Data Compass. It's intended for the drive with severe bad sectors. When Shadow disk is connected and enabled, it will “mirror” the manipulation on source disk.
Every time when Data Compass successfully reads a sector on source disk, it will at the same time write the sector on shadow disk. And next time, when the sector needed to be read again, Data Compass will read the content from Shadow disk in the aim of protecting source disk.
2.4 Why I can't register my Data Compass?
There are two reasons for that:
1. PC Configuration. We have tested in PC with Intel 845/865/915 chipset Motherboard and we recommend Intel 915 chipset Motherboard.
Further more, USB interface of Data Compass adopts the standard of USB 2.0, so make sure there is USB 2.0 driver installed in your PC.
2. Operation System. We recommend you install English OS as we find registration fails on non-English OS.2.5 Can Data Compass extract data from undetectable drives?
For Hitachi drives, if key modules (P-list related) are not damaged, We can use Data Compass to load the internal resource to access data area and extract data. But this is not for all undetectable drives.
We are still researching the possibility to apply the technique on other brand drive.
