I had tried recovery software on my drive without success; it was a hardware problem. Sending it to Essential was something of a Hail Mary, and she must have been listening! Tom and Sarah have been great, and have effected, as far as I can see, a complete recovery of the drive's contents. Their communication was excellent, and service very prompt. The recovery took a few days, but was thoroughly executed and well worth the wait. I cannot recommend them highly enough. Stellar job, guys!
