Common questions
Can you recover data from a failed Promise Pegasus?
In most cases, yes. We first check whether the drive uses a USB-native board or hardware encryption, then repair the board or bypass the bridge so the drive can be imaged safely.
Where do I find my external drive model number?
Check the label underneath the drive, or the product code on the original box.
What does data recovery cost?
Every case starts with a professional evaluation (£94.80), followed by a fixed quote.
