With the Guardonix Professional almost the same price as the RapidSpar USB Add-on, what are some of the things you find the Guardonix particularly useful for? According to Serge, the Guardonix Pro - even with its improved bad sector handling - has much longer read timeouts than the RapidSpar.
Do you mind helping me understand the reason one might go with the Guardonix as a write-blocker, instead of imaging with the RapidSpar and USB Add-on? I could see the value for a forensics professional that does not already own a RapidSpar?
Also, do you happen to know if the Data Acquisition Add-on FS mount feature works with the USB Add-on?
As far as the data recovery edition stabilizing drives for work with PC3K, I can see the use for that.
Edit: wording and added additional question about Data Acquisition add-on.
