or data. This article identifies the symptoms of physical hard drive failure. Symptoms of a Physical Hard Drive Failure There are a number of warning factors that can alert you to a physical drive failure. These include: Drive shows as how to recover data from hard disk which is not detecting "Not Initialized" in Windows Disk Management; Drive not spinning (no power); An excessively hot drive; An how to recover data from crashed hard disk abnormal ticking noise whilst the drive is reading data; A loud clicking or grinding noise. A Note Re. External USB Hard Drive Data Recovery An how to recover data from external hard disk external USB drive adds another layer of USB electronics between the hard disk and the computer. These USB components are also subject to failure. When dealing with a failed external drive, part of the diagnostic procedure is to remove the drive data recovery from hard disk software free download full version from its case and try an alternate connection. 1. Not Initialized in Windows Disk Management Windows > Disk Management lists the physical drives recognized by the computer and the way in which the space on those drives is allocated. A "not initialized" error is a signal of a fundamental communication error. Usually an attempt to initialize a hardware failed drive will result in a low level "I/O" (Input / Output) error. 2. Drive Not Spinning (no power) If a correctly powered drive

is not spinning (i.e. it is silent) it can be an indication of a problem with the hard drive Printed Circuit Board (PCB). The PCB holds the electronics responsible for controlling the operation of the drive and its communication with the computer. It is possible to replace a printed circuit board, but this should only be undertaken by an experienced hard drive data recovery professional. It is essential that the replacement PCB not only be an identical make and model, but it must also hold the identical firmware to the original board. 3. Excessively Hot Drive A traditional (non Solid State) drive contains disks called 'platters'. These platters are coated with a magnetic substance and spin at high speed under an mechanical arm (the 'actuator' arm) that moves backwards and forwards over the surface of each platter. On the end of this metallic arm is a small copper wire. The computer sends a pulse through this wire which changes the state of the magnetic surface of a platter as it passes underneath. In this way the files that you store on your computer are encoded into the magnetic substance. The tolerances within a hard drive are finely calibrated. As with any mechanical moving parts, the friction in movement creates heat. A physical problem (or pending physical problem) may therefore present as an abnormally hot drive. 4. Abnormal Ticking Noise In some instances a failing hard drive can present with an abnormal ticking noise whilst
alpha or beta version. If new version also doesn't help, read this manual. Required software: 7-Zip (latest version, that can be stable, alpha or beta version). Some program with hex viewer or editor, for example, FAR Manager. 7z archive structure 7z archive consists of 4 main blocks of data: Start Header

(32 bytes): it contains signature and link to End Header Compressed Data of files Compressed Metadata Block for how to recover data from hard disk after format files: it contains links to Compressed Data, information about compression methods, CRC, file names, sizes, timestamps and so on. End Header: it contains link to Compressed Metadata Block. how to recover data from hard disk using command prompt Note: If 7z archive contains only one file without encryption, 7-Zip stores Metadata for that file in End Header in uncompressed form, and there are only 3 main blocks in that case. Archive example Archive example: a.7z (3740 bytes) that contains 5 files compressed with LZMA http://www.recovermyfiles.com/hard-drive-data-recovery.php method. Start of archive: 0000000000: 37 7A BC AF 27 1C 00 04 5B 38 BE F9 59 0E 00 00 0000000010: 00 00 00 00 23 00 00 00 00 00 00 00 7A 63 68 FD 0000000020: 00 21 16 89 6C 71 3D AB 7D 89 E6 3C 2E BE 60 24 00: 6 bytes: 37 7A BC AF 27 1C - Signature 06: 2 bytes: 00 04 - Format version 08: 4 bytes: 5B 38 BE F9 - CRC of the following 12 bytes 0C: 8 bytes: 59 0E http://www.7-zip.org/recover.html 00 00 00 00 00 00 - relative offset of End Header 14: 8 bytes: 23 00 00 00 00 00 00 00 - the length of End Header 1C: 4 bytes: 7A 63 68 FD - CRC of the End Header Relative offset of End Header is relative from the end of Start Header, that is at offset 0x20 (32 in decimal). Real offset of End Header in example archive = 0x20 + 0x0E59 = 0x0E79 20: 00 21 16 89 ... - start of compressed data. Note: if the file was compressed with LZMA method, the first byte is always 00. If first byte is not 00, then archive uses another method (it can be LZMA2 or encrypted data with AES). End of archive: End Header (offset = 0x0E59, length = 0x23): 0000000E70: 17 06 8D AD 01 09 80 0000000E80: AC 00 07 0B 01 00 01 23 03 01 01 05 5D 00 10 00 0000000E90: 00 0C 81 1A 0A 01 3C 70 52 F7 00 00 Possible values for first byte in End Header: 17 - End Header contains the link to Metadata Block. 01 - Metadata block is stored in End Header. Corruption types There are some possible cases when archive is corrupted: You can open archive and you can see the list of files, but when you press Extract or Test command, there are some errors: Data Error or CRC Error. When you open archive, you get message "Can not open file 'a.7z' as archive" Corruption case: Data errors or CRC errors for files inside archive Here we describe the case, when you can open archive and you s
