The enemies of disk drives are dust, heat, impacts, liquid, voltage spikes, and Windows (I might be kidding about Windows). Let’s address them one at a time and what to do about them.

Liquid.

Don’t use your computer in the bathtub. Don’t use your computer around happy hour. Don’t spill your double mocha soy latte on your keyboard. I have dealt with recovering data resulting from spills around the latter two conditions. Yes, all the data came off, but martinis, coffee, and most other liquids simply don’t mix with electronic components. It’s useful to get a keyboard protector “skin” if you must imbibe and compute simultaneously.

In the very early 80’s, IBM introduced the IBM PC, progenitor of most modern personal computers. That same year, undoubtedly, the first PC hard disk failed and someone was screaming about their data and cursing IBM. Shortly after that, we started the data recovery industry and created most of the established practices and recovery techniques in use today. Over the years we’ve seen quite a few pieces of misguided advice about recovering data in the popular media, and heard many others. I don’t know if we’ve heard it all, but we’ve heard these:

Slap it, heat it, hit it, freeze it, drop it, tap it, swap the board, open it and spin it, use Norton, spin it with a drill, use a higher voltage, it will fix itself, and pray.

Don’t let your computer fool you - back up new data daily.

It’s important that you keep two alternating backups, and an additional spare piece of media. This means to have one disk (or tape, or thumb drive) labeled “EVEN” (for even-numbered days, one labeled “ODD” and one spare. Eventually, something will go wrong with a backup. For example, if an error occurs on an “EVEN” day, and you put in your “ODD” backup, you may ruin both. Instead, put in the spare. If there is a problem, you’ve saved your extra backup (from the day before yesterday) and have not wasted all your hard work. If there is no problem, and it was only a temporary glitch, then put your spare back on the shelf, reformat the “EVEN”, and carry on with your backup.

In the privacy of our studies, offices, libraries, or wherever it is we have our computers, it may seem that we are alone, with no one looking over our shoulders. But every document we draft, every step through the Internet we take, is creating tracks through the digital environment in our computers. This fact has a number of implications, both useful and detrimental.

What happens when drafting a document?

Mac computers have different configurations that the everyday Desktop PC’s we all use. Hence if you have a Mac and the hard disk crashed or there is data inaccessibility problem then you will need to consult a specialist for Mac data recovery.

Most of the Mac data recovery services also offer professional recovery software’s that can salvage the hard disk and recover lost. Most of the times, the data loss occurs due to damaged HFS, or HFS and file Systems of Macintosh Operating Systems.
