Hard drive data loss can occur for many reasons. You cannot insure yourself against it, but you can reduce the possibility of such sequence of events. Firstly, you should not overheat the drive. The spinning speed of modern hard drive platters is much higher than it has been before and, thus, it generates even more heat. Just like unskilled forex trading increases the risk of loosing your investments, in the same way an increase of spinning speed of hard drive increases the chances of disk overheating, which may result in motor failure. Installing a cooler fan will help to avoid overheating. Shaking and bumping of hard drive are unacceptable since it is sensitive to vibrations and requires delicate handling. That is why you should not forget about basic precautions for handling this device, which by the way is required when working on forex as well. Failing the above, disk heads can be destructed followed by complete data loss. Therefore, you should transport and handle the disk with great care and caution. If the electricity network is faulty and there arefrequent power fluctuations, you can secure your hard disk by installing a special uninterruptiblepower supply unit. It is also advised that you copy crucial information to another carrier(DVD, CD etc.). After doing that you can rest assured that your data is safe, like you can be confident insuccessful workon currency stock exchange if you follow, study and analyze financial market news and adhere to the direction of its development.Now abouthackers and viruses. You should not forget that hackers are very advanced people in terms of technologies and related stuff, and there is no limit totheir ingenuity. Viruses developed by hackers can destruct and infect all information on yourhard driveor damage a part of it. So what is the way out? You can secure yourself from viruses by installing antivirus and regularly updating it. A probability of security and safety of your data in case you have a good andup-to-date antivirusincreases manifold.Another way of avoiding unnecessary damages to hard disk is todefragment your hard drive disk regularly. By doing that, your data will regroup in such a way that the speed of hard drive and chances of data recovery will rapidly rise. Please be careful when you work with different tools/utilities, and make sure that they are fully compatible with your operating system.Only by following andadhering to the above tipsyou will get apositive and productive workfrom your computer and hard drive, just like the work of forex market.

Intro Apple has developed its own file system called HFS (Hierarchical File System) for using in the Mac OS, . Currently, it was replaced by HFS +, which is used in Mac OS from version 8.1 on. The volume structure using HFS + is similar to HFS, but at the same time they slightly differ. The main characteristics of the two systems: The length of a file name: · HFS:31 · HFS+: 255. File name encoding: · HFS: Mac Roman · HFS+: Unicode Catalog node · HFS: 512 Kb · HFS+: 4 Kb Maximum file size · HFS: 2^31 · HFS+: 2^63 As you can see, HFS + was created to make the best use ofdisk spaceon large volumes and fragmented files. HFS+ from the inside HFS divides the disk space into equal-sized blocks. The 16-bit fields are used to identify a block, therefore, there can be 65,536 of such blocks in total, and each block occupies an integral number of sectors. Obviously, such a system results in a loss of much space in large volumes. In turn, HFS+ uses 32-bit values for block numbering, which allows using the space more efficiently. To manage the data arrangement on a drive, HFS+ stores control footing on it, too, that is metadata. The following are the the most critical for the file system and the most interesting to us in the search for the missing data · Volume header. Contains general information about the volume. For example, the size of the data fork and information on the location of other metadata blocks on the disk. · Allocation file. Bitmap, where the status of each block on the disk is marked. (1 - in use, 0 - free.) · Catalog file. It stores most of the data on the arrangement of files and folders on the disk. · Extents overflow file. Contains additional metadata that did not fit in the catalog file. · Attributes file. Used for access check, etc. · Journal file. Stores information about transactions committed for this volume. · Catalog file, extents overflow file and attribute file are organized as B-trees. The volume header is always stored at fixed offset 1024 bytes from the start of the volume. It contains information about the volume as a whole, including the location of other HFS+ key structures on the disk.. For example, journalInfoBlock - journal allocation, if the system has a journal, allocationFile - a block from which a map of file allocation on the disk starts, catalogFile - catalog file allocation.
