- Hardware data recovery
Along with fast development of information in 21st century, computers have been applied to commercially and individually aspects with a remarkable growing speed. So it makes various electronic information, namely, the data - - become important and valuable property which cannot get lost both for enterprises or individuals. How to guarantee the integrity, usability and security of storage data has then become a crucial question day by day. As we know, data recovery can be category in to 3 levels Level 1 Logical Data Recovery. Applicable for Hard Drives manifest itself as following symptoms: Partition Loss, File corruption Virus Attack, Accidental Disk Format, File deletion… Of all the levels, this is the most widely performed. However, according to the relevant reports only 20-30% percent of all the data recovery cases can be addressed using software tools alone. On the other hand, if software tools are applied alone the risk of losing user data increases significantly, which undermines any professional data recovery level. Recovery Time = 1 Day Price = $375-$550 Level 2 Firmware and bad sector Restoration Disk manifest itself as follows 1. HDD is identified incorrectly. 2. HDD starts the motor and then hangs. 3. HDD capacity is identified incorrectly in the BIOS, usually less. 4. HDD can identify correctly in the BIOS, but all sectors are displayed as bad sectors, or disk partitioning is impossible. 5. HDD is very slow in reading/writing/formatting. Recovery Time = 1 - 2 Day Price = $650-$1100 Level 3. Hardware or mechanical data recovery This level handles with hardware component issues which can't be repaired but the only solution is to have the components exchanged using donor parts. Strictly speaking, Level 3 is part of Level 2: Firmware and bad sector Restoration. Such as Head stack problems, Spindle motor problems and Platter Alignment & spacer problems Recovery Time= at least 2 day Price= at least USD1000 A lot of data recovery companies focus on Level 1 and Level 2 data recovery, but not Level 3. Why do not they want to dig gold form Level 3? The answer is very simple, they consider that Level 3 hardware or mechanical data recovery is too hard to deal with. Actually, it was a challenge problem for all the DR experts in a few years before. Except we have to invest hundreds of thousands money into this field for establishing a class 100 clean room, technique problems can not be overcome. For Head stack problems: how to dismount the head stack and then reinstall properly without damaging the sensitive heads is the key. Spindle motor problems: only a few top professionals with plenty of practical experience can handle spindle motor problems Platter alignment & spacer problems: so far they are still a headache for most of us without proper tools However, since a few professional data recovery tool providers researched and develop into this depth level, some easy to use and cost effective tools was launched successfully and have been gaining a popularity from DR experts, IT technicians and Forensics. The tool can assure you to operate on your HD on a relatively stable table, making your job easier and more reliable. Also, maintains the original cylinder status by removing and placing each platter of the multiple platters together, so that allows you to change multiple platters without moving the platters out of alignment with each other which otherwise will result in data corruption. Class 100 clean room can provide a good environment for drive disassembly and head/platter exchange. But it is not absolutely indispensible. This job also can be done successfully in a closed clean space. If you want to know more about data recovery hardware, please go to Google search.
- Common Data Recovery Myths - Clean Room
Clean rooms are used to repair failed hard disk drives. These designated rooms remove all the damaging air particles, protecting the platters from being exposed to clinging dust and microbes that can cause data storage to error (bad sectors). Clean rooms cost thousands of dollars a month to maintain, so the idea that a clean room can be made within the home is far fetched.
- Excel File Not in Recognized Format
MS Excel is a worldwide fashionable application, offered in MS Office suit, which allows you to make spreadsheets, featuring various graphing and computation tools. Until Excel 2007, the proprietary file extension used was .xls, which is also known as BIFF. The file format scene changed in Excel 2007, when Office 2007 introduced a new set of file systems for its applications including MS Excel. In Excel 2007, the new system is XML-based, Office Open XML. Excel 2007 uses .xlsx extension to save the workbooks.
- Resolving OLT Corruption in UNIX Operating System
Superblock in UNIX operating system contains important information about the file system like file system type, vital numbers describing this file system’s geometry, behavioral tuning parameters, disk layout version number and more. The OLT (Object Location Table), which is referenced from the superblock, is primarily used to at the time of mounting the file system. The information saved in OLT is used to locate the file system structures that are not in fixed locations. Corruption or damage to OLT mainly occurs due to file system damage, unexpected system shutdown, malicious software like virus and more. Two outcomes that you encounter after OLT has been damaged are unbootable hard drive and data inaccessibility. To overcome such situations, you need to restore the data from an up-to-date backup. However, if no backup is available or backup falls short to recover the required data, you need to opt for advanced UnixWare data Recovery tool.
- Data Loss due to Inode Corruption
SCO UnixWare operating system is a Unix-based operating system that is primarily known for its reliability, stability and scalability. While the operating system is safe and reliable, it can also be corrupted and unmountable due to super block damage or corruption, inode corruption, boot errors, VTOC (Volume Tables of Contents) damage, OLT (Object Location Table) damage and malicious software like virus. In most cases of operating system corruption, you encounter an error message. Once you encounter the error message, the data stored in the hard drive becomes inaccessible. To overcome such situations, the best possible way is to restore the data from an up-to-date backup. However, in case of no backup availability or backup failing short of restoring the required data, you need to use advanced SCO UnixWare Data Recovery Software.
- Recovering BKF Files
People working on computers are familiar with the word ‘Backup’. File backups are generally kept for avoiding any kind of future data crisis that is inevitable. One cannot deny the fact that file corruptions are unforeseen and can erupt anytime without any prior notice. So, having backups becomes mandatory and one should practice it for maintaining continuous flow of information. NTBackup or NTBackup.exe is one backup tool that comes with Microsoft Windows. It creates backup files with extension .BKF.
- How to Rescue Lost Data from Falsh Memory Cards
The overall memory market had grown at a strong growth rate till 2008. Flash memory is the core of memory market. The NAND segment overtook the NOR segment in market share.Mobile phone,digital camera, USB Pen drive, and MP3/MP4/PSP are major applications of NAND flash memory.SD formats, SD, MiniSD, and SDmicro,CF,SSD,etc.generate approximately one-half of total flash card unit shipments.Nowadays flash memory products already play a more and more important role in our daily life. A research report indicates that nowadays the quality of Flash Products in the market is uneven,most of them are made by B-Grade storage chips.That's why the flash products are so cheap in the market at present.As a result,the Flash Products are easily got corrupt and data will be lost due to the bad quality,besides,power failure, hardware or software malfunction, virus attacked also can make you loss your data.Nowadays there are many flash recovery software in the market which can help you get the lost data,but usually they can only deal with simple cases such as delete and format situations.Some other Flash Data Recovery Tools such as PC3000-Flash and Flash Tool from Atola,which are much better than the above softwares.They can do the work that the software cannot do,for example,they can recover the data from a undective flash storage which cannot be solved by the softwares.But the main disadvantage of PC3000 or Atola's tools is that the support flash vendor list is limited,cannot support the new coming flash memory in the market.However,we still have further choice,It is said that a hardware-software complex Flash Data Recovery Tool called Flash Doctor produced by SalvationDATA will be released recently,from its data sheet,we can see that it can recover all the flash memory cards whether it is an old flash product or it is new products just appear on the market in the market by directly access the memory cards' file system.By using this tool,we can retrieves data from various memory cards storage media including digital camera, mobile phones, mp3 music player, handheld computer, Pocket PC, PDA etc.And it fully supports restoration of all type of digital files such as WAV, MPG, MPEG, TIF, GIF, MP3, JPG, JPEG, BMP, MIDI files and directories information.

- Enabling Write Caching In Windows 2000 May Cause File Loss
To provide enhanced data writing and reading speed, hard drive use caching techniques and write caching is one among them. The write caching is the method for hard drive to improve system performance by foreseeing what the system would do next. If you have write caching enabled on your hard drive, when operating system sends write command to hard drive, it directly tells the system that write operation is complete (even though data hasn’t been written to the disk yet). In some cases, when you enable write caching on Windows 2000, you might come across file loss situations. At this point, having a powerful File Recovery Software is required to sort out the issue.
- Learn More about the Dashboards
In the management information system, the Microsoft Access dashboard is basically an information system with the executive functions. It is designed in such a way that it allows the user to read easily. It is similar to the dashboard that is present in the vehicles. For an example, the product may get the information from local operating system in the computer, from a single or several applications which might be running, and from 1 or few inaccessible websites on the internet and then present it in a manner that it seems that it all has been made available from a single and the same source.
- Common Data Recovery Myths - The Freezer
This particular myth has been around since the age of the hard drives, it also happens to be one of the more popular once since there is some truth to the science behind it. At glance this myth looks promising for hard drive repair or data recovery however the end result of freezing your hard drive is ultimate failure and corruption of the inner working components.
