## System Requirements

### Common Requirements

- Drives: without significant hardware/firmware problems
  Attention! If there are physical problems (extraneous sounds, error messages, slow performance, etc.) it is recommended to appeal to specialists
- CPU: Intel compatible (i486 and higher)
- To save/use results, reports, and settings a valid partition is required which is supported by the operating system (in particular, FAT partition is required to work in DOS/Win9x/ME)

#### If Device Size Is Detected Incorrectly

This must be resolved before any further work. Some issues are quite simple - see guide from external source. Some issues are below:

- Capacity Limitation Jumper is misplaced (device size is limited to 32GB)
- HPA is erroneously applyed. Device size usually becomes 1TB less or similar (typical to some GYGABYTE motherboards). Try software: HDD Capacity Restore Tool (Windows), hdparm (Linux), HDAT2, MHDD, Victoria (DOS)
- No large drive support on OS - see below
- Incorrect drivers for SATA/USB controller (no correct 3TB+ support). Device is displayed tipically 2.2TB less. Update drivers
- USB enclosure / another adapter has no correct 3TB+ support. Change adapter or attach device directly

### Windows 2K+ (2K/XP/Vista/7/higher)

- Recommended: Windows XP + SP2 and higher
- 32-bit versions work in both 32-bit and 64-bit Windows
- Administrator privileges
- Drives: supported by OS
  Attention! To work with drives larger than 2TB under Windows Vista/7/higher the most recent versions of controller drivers must be installed. To work with 128GB and larger drives under Windows 2K/XP certain ServicePacks must be installed and LBA48 support must be switched on in the system registers. Windows 2K/XP does not support drives larger than 2TB.

### Windows 98/ME

- Drives: supported by OS
  Attention! Windows 9x/ME handles 128GB and larger drives incorrectly unless special patches are installed. You may reload computer in MS-DOS mode and use DOS version to access drives via BIOS or ATA-interface

### DOS

- OS: MS-DOS 5.0+ compatible
- Drives: supported by BIOS or supported by DOS (using ASPI drivers) or supporting ATA-interface (IDE or SATA). SATA disks must be switched to IDE-compatible mode in BIOS settings for direct ATA-access
- DOS Extender (file CWSDPMI.EXE © 2000 CW Sandmann in the software directory is enough)
- At least 200 KB of low memory free
- At least 64 MB of extended memory
- For extended name duplicates handling during data recovery long name driver is required (e.g., DOSLFN.COM © Haftman software)
- If you wish to use a mouse then mouse driver for DOS is required

### Linux

- OS: Latest Linux distributions with libc library
- 32-bit shared libraries to run 32-bit versions on 64-bit Linux (e.g. libc6-i386 package)
- Drives: supported by OS
- Superuser rights
- Root terminal or terminal emulator (xterm, Konsole, Gnome-Terminal, etc.)
- utf-8 locale support
