When you have backed up meticulously every day for the last 5 years, then you find that the only time you require to restore the backup, you discover the tape wont load because of a tape error.

So what can you do. There are several software options for backup data recovery, but most of these only work on backup files, so how do you recover data from a tape?

Data Recovery Engineering Software Limited write software mainly for data recovery companies, and one of their titles is a very cost effective tape copying tool.

The software creates an image file of the data on the tape to hard disk. Now you can access the data on the tape and recover it with your backup recovery software.

Another use for the software is when someone has created a backup set that you need to access, but it is password protected (not encrypted) and the user cant remember the password or left the company. Or a forensics examiner needs to look at the data stored on the tape but does not have access to the software used to create the backup.

Temperature Humidity Chambers are available from various chamber manufacturers such as Thermotron, Tenney, Espec, Blue M, Despatch, Ransco, TestEquity, Associated Environmental, Bemco, Cincinnati Sub Zero, BMA, Lunaire etc. When buying a Temperature Humidity Chamber, there are a number of things to consider amongst which are:

(a) of the chamber|The inside dimensions of the temperature humidity chamber|Minimum Internal Dimensions of Chamber[/spin]. This will be decided by the size of the product to be tested.

(b)Temperature Range required for the test you intend performing. The maximum range of a Temperature Humidity Chamber is normally from -73C to +200C. However, to perform this full range the chamber will need to have two compressors in what is referred to as a cascade refrigeration system. If only a single compressor is used, then a temperature range of down to approximately -35C is possible. Keep in mind that humidity testing can not be performed below 0C (freezing point) and that any testing below 0C will be possible for temperature only testing (humidity function will be disabled). Temperature Humidity Chambers are also offered without any refrigeration at all. The lowest temperatures at which testing can be performed without refrigeration is normally about 12C above ambient.

(c) Humidity Range required for the test you intend performing. Even though most Temperature Humidity Chambers claim that they have a humidity range of 20% to 95%, what is often not taken into account is the temperature range at which these humidity levels can be controlled. For example, at 25C, the lowest humidity obtainable by most chambers with refrigeration will be about 45% (unless a dehumidifier package is installed). At temperatures above 25C, lower humidity levels than 45% can be controlled. Normally graphs are provided by the manufacturer indicating the temperature versus humidity range of the temperature humidity chamber.

(d) Water Recycling System - If no drain is available to drain the excess water used to create the humidity, one should consider a water recycling system consisting of a water storage container, recycling pump and demineralizer cartridge. This will recycle the water so that a drain is not required. Remember, demineralized water should be used for Temperature Humidity Chambers, not deionized water which can harm the interior of the chamber (usually stainless steel) and other components!

If you’re interested in the latest technology, then solid state drives have probably been on your radar for awhile now.  Also, known as an SSD, these drives are being hyped as the next wave of greatness for laptops and for computers in general.

The big question, however, is do they deliver on all of these promises or, like so many grand advancements promoted in the past, just overhyped.

To answer those questions, we first need to learn a little bit more about these drives.  Then we’ll delve into how they stack up to their promises.

A Little Background

Basically, these drives aren’t new but they made a huge splash in 2007 at the Consumer Electronic Show held in Las Vegas.  They were heralded as the solution to many problems facing those of us who love portable computing.

These drives have been in use in military and commercial applications for a lot longer but the huge cost has never really made them a viable consumer purchase until prices have started to come down. Continue reading »
