- TIRAMISU - SOPHISTICATED DATA RECOVERY V3.03
- (c) 1996 by Plug'n Play, Uwe Gissemann
-
-
- INTRODUCTION
-
- TIRAMISU is a software for reconstructing data from a crashed hard drive.
- It helps when the drive is
-
- - hit by a virus
- - formatted
- - 'fdisk'ed
- - zapped by a power failure
- - damaged by applications
-
- TIRAMISU scans the drive even when there are physical damages. The found
- data are analyzed and reconstructed. TIRAMISU can handle drives without
- readable boot sector, readable Fat or readable directories. It can
- handle drives that are not recognized by DOS anymore.
-
- TIRAMISU automatically creates a VIRTUAL DRIVE in memory. This virtual drive
- looks like a usual file manager. You can see the lost directories and files
- of your crashed drive. Now files and directories can be viewed and copied
- to a safe medium.
-
- The extensive use of our sophisticated pattern recognition technology
- enables TIRAMISU to put the right pieces of data together again. Even
- disks with very few administrative informations left can reach a high
- recovery quality.
- TIRAMISU recovers much more data than any other 'disk doctor'.
-
- TIRAMISU is NON DESTRUCTIVE and READ ONLY. It does not put any data onto
- your crashed drive. Recovered data are restored to another destination
- (disk, diskette, network, interlink).
-
- TIRAMISU works on DOS and Windows platforms. Better Windows95 support
- has been added in version 1.03. Multi partition recovery has been added
- in version 2.0.
-
- A version for NOVELL is available too. A version for HPFS is under
- development.
-
-
- SYSTEM REQUIREMENTS
-
- - 286 processor and up
- - 4 MB RAM and up
-
- Depending on the size of the drive to be recovered we recommend a 486 with
- 8 MB RAM. Installing 5 MB of EMS (Version 4) is recommended.
-
-
- GETTING STARTED
-
- 1) Boot diskette
-
- Create a boot diskette with a CONFIG.SYS similar to this:
-
- files=25
- device=himem.sys
- device=emm386.exe
-
- Make sure you have specified the correct drive parameters in BIOS setup.
- Boot the computer and start the program TIRAMISU.EXE.
-
-
- 2) Specify swap area
-
- By default TIRAMISU uses EMS as swap area. If for some reason there is
- no or not enough EMS you can specify a swap area on disk.
- Select OPTION -> DATA RECOVERY, tag 'DISK ALLOWED', specify path.
- CAUTION: Do not swap to the drive you intend to recover.
-
-
- 3) Hit RECOVER for the drive you want to recover. You can switch between
- the drive using the TAB key.
-
- TIRAMISU starts processing. Depending on your system's speed and the size
- of your drive this can take 5 minutes or even up to 1 hour.
-
-
- 4) Copy some or all files to a safe medium using F7
-
- Now you see the virtual drive and you can view and copy (registered
- version only) the files to any DOS-available destination.
-
- THAT'S IT! ISN'T IT EASY?
-
-
- RESTRICTIONS
-
- TIRAMISU handles only drives with 16-Bit Fats, which applies to most
- systems. Only old (10 MB) drives have another Fat (12-Bit).
-
- Since TIRAMISU is very memory hungry, your PC might run
- out of memory. If you face this problem, install a memory manager with as
- much RAM and EMS as possible.
- Watch the available memory displayed at the bottom line. The value displayed
- at the far right shows the free RAM. The E:XXX shows the free EMS and the
- F:XXX shows the fragmentation.
- The RAM should not go below 50000.
-
-
- OPTIONS
-
- There are several options you can change in the OPTIONS->DATA RECOVERY
- screen.
-
- - Swap Area
- By default TIRAMISU stores memory intensive data in EMS. If your have no
- or not enough EMS available you can allow swapping to a drive. Be sure to
- choose a drive you are not just recovering.
-
- - Excluded Main Directory Entries
- This option tells TIRAMISU to ignore files entries that have been created
- during a previous run of another disk doctor (Norton, Scandisk,...).
-
- - Logging
- Use this option to create a log file of TIRAMISU's processing. This might
- be interesting for debug purposes.
-
- - Automatic Identification
- The first thing TIRAMISU does is to retrieve the original structure of
- the file system: place of Fat1, Fat2, main directory, number of sectors
- per cluster, number of clusters.
- If you tag off this option TIRAMISU shows you what it thinks what kind
- of file system it found. Usually you confirm this by pressing OK. If you
- can not confirm the structure TIRAMISU found, you can continue the
- identification procedure by pressing SEARCH AGAIN. After a while TIRAMISU
- will make a new proposal.
-
- - Start Identification At Sector X
- By default TIRAMISU starts its identification procedure at sector 0.
- However you might be interested in recovering another but the first
- partition. Then you can enter a value in this field.
- Example: Let's suppose you have a 600 MB drive with two partions (400 MB
- and 200 MB). You want to recover the second (200 MB) partition. The first
- partition uses 400 MB space on the hard drive. These are approximately
- 800000 sectors (one sector has 512 bytes). Consequently you should enter
- the value 800000 in this field.
- You should tag the "Automatic Identifation" off. So you can verify if
- TIRAMISU retrieved the correct file system structure.
-
- - Bad File Entry Acceptance
- TIRAMISU uses statistical algorithms to decide if file entries are
- included into the recovery process. If you set this option to 0
- TIRAMISU is very strict. If you set it to 100 TIRAMISU is very loose.
- 50 is a good value. Increase it if you miss some files in the resulting
- virtual drive. Decrease it if you get scrambled results.
-
-
- TROUBLE SHOOTING
-
- Sometimes you might think the computer is frozen and TIRAMISU is
- crashed. Be patient! Some procedures might take up to one hour. If
- TIRAMISU crashes you usually get an error code.
-
- If you get only scrambled results this could be due to the TIRAMISU
- drive structure recognition routine. Try this:
- Select OPTION -> DATA RECOVERY, tag 'AUTOMATIC IDENTIFICATION' off.
- Press RECOVER. After a while you get a window that proposes a certain
- drive structure. If you are not satisfied with what you see you can
- press 'Search Again'. TIRAMISU tries to retrieve another structure.
- Finally press 'Ok'.
-
- You can change the Option "Bad file entry acceptance". 0% means a
- very strong directory recognition routine. Use only if TIRAMISU crashes.
- 100% means a very loose directory recognition routine. Use if TIRAMISU
- goes through but you miss some directories. 50% is a good standard value.
-
- You should not use any other 'disk doctor' before running TIRAMISU. If you
- did so, please 'undo'.
- If you cannot 'undo' you can tell TIRAMISU to ignore the file entries
- the 'disk doctor' created (something like FILE0000.CHK...).
- Select OPTION -> DATA RECOVERY, modify the field 'Exclude Main
- Directory Entries'.
-
- Upload a new version from our Internet site (address below).
-
- If you find any bugs, please send a description to one of the addresses
- below.
-
-
- REGISTRATION
-
- TIRAMISU IS DISTRIBUTED AS SHAREWARE. FEEL FREE TO COPY, DISTRIBUTE OR
- UPLOAD IT TO ANY MEDIUM. The unregistered version has all functions
- for recovering your crashed hard drive. But only the registered version
- of TIRAMISU allows you to COPY files from your recovered drive.
-
- There are two kinds of licenses available:
-
- - A limited version that can only be used for a PERIOD OF ONE WEEK.
- In effect this is a PAY PER USE registration. The fee is
- DM 145 (approximately US $99).

-
- - Select REGISTRATION->REGISTRATION. You will be asked to insert a
- diskette in drive A:. Please have ready a blank formatted 1.44 MB or
- 1.2 MB diskette. This diskette will become your license diskette
- later. Be aware that any data on this diskette might be damaged
- during this procedure.
- If you encounter any problems please try it again using a fresh
- formatted and error free diskette.
- Finally you will be shown a 16- or 17-letter code.
