Promise Pegasus: specifications & data recovery

About the Promise Pegasus

Long-standing favourites in Mac studios. Controller failures and broken RAID 5 rebuilds are the usual causes of lost volumes.

How we recover Promise Pegasus data

Portable drives are handled according to their internal design: standard SATA drives are imaged directly, USB-native and encrypted models are recovered through their original electronics.

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.
