NTFS Recovery:
A file system is the computer data storage system on the HDD. The most common file systems are FAT16 for older, FAT32 and NTFS. FAT stands for File Allocation Table.
NTFS stands for NT File System which was first used in Windows NT (thus the name). It boast s better reliability, security (as it has added security for file loss), and file management than the older FAT System.
Both systems have advantages and disadvantages. NTFS is considered to be a far more secure, in addition to offering more flexible cluster sizes as a file systems than any of the FAT's. The cluster sizes can be modified to as low as 512bytes, which means almost no wasted space on the hard disk. The maximum disk size is an incredible 18.5 x 10¹º bytes, which is gigantic!
EFS - Encrypting File System. Encrypted Files and Folders (NTFS5 only)
The Encrypting File System (EFS) provides the core file encryption technology used to store encrypted files on NTFS volumes. EFS keeps files safe from intruders who might gain unauthorized physical access to sensitive, stored data (for example, by stealing a portable computer or external disk drive).
Users work with encrypted files and folders just as they do with any other files and folders. Encryption is transparent to the user who encrypted the file; the system automatically decrypts the file or folder when the user accesses. When the file is saved, encryption is reapplied. Users who are not authorized to access the encrypted files or folders transparently receive an “Access denied” message if they try to open, copy, move, or rename the encrypted file or folder. The exact message text may vary depending on application which tries to access the file, because it is related not to user rights for file but to ability of EFS to decrypt file using user's private key.
EFS has the following benefits over 3rd party encrypting applications:
- It is transparent for user and any applications. There's no risk for user to forget to encrypt file and leave data unprotected. Once file or folder is marked as encrypted, it will be encrypted in background without interaction with user. User does not need to remember password to decrypt files.
- Strong key security. In contrast to other solutions when keys are based on user entered pass-phrase, EFS generates keys which are tolerant to dictionary based attacks.
- All encrypting/decrypting processes are performed in kernel mode, excluding the risk of leaving key in paging file, from where it could be possibly extracted.
- EFS provides data recovery mechanism which is valuable in business environment, giving an organization an opportunity to restore data even if the employee who encrypted it left the company.
UniRecovery is capable of recovering data from the following cases of data loss:
- Formatted Drive.
- Clicking drives
- Inaccessible Drive
- Corrupt or Damaged Partition Table.
- Drive Not Booting Missing File/Directory Deleted File/Directory.

 A single speck of dust entering a hard disk could cause fatal results. It is larger than the distance between the read/write heads and the platter in a hard disk (40 microns, a human hair being 100 microns thick) and its collision with the Hard Disk head would be extremely detrimental. The air quality of the Clean Rooms complies with the applicable standards BS 5295, ISO 14644-4 and Federal Standard 209. Hard disk fabrication requires a ‘Class 100’ Clean Room and UniRecovery undertake all laptop hard drive recovery work with brands whether external drives such as Lacie, Freecom, or Omega or internal such as Maxtor, Seagate, Western Digital, Hitachi, Samsung, Compaq, HP, Fujitsu, Quantum and IBM in Clean Rooms ‘Class 10’. Commonly established, recovery from “Clicking” hard disk drives, can also be achieved under these specialised Clean Room conditions. Some of the most common Hard Disk for Desktops server related problems we can recover data from:
