- REVISION: 3.6
-
-
- This utility scans the media and remaps any grown defects on
- a Western Digital drive. It also provides performance data
- such as seek times and data access times.
-
-
- COMMAND LINE OPTIONS:
-
- To run the menu-driven test, type 'WDAT_IDE' from the DOS
- prompt.
-
- The following options may be included on the command line
- after 'WDAT_IDE':
-
- L = open NEW log file WDAT_IDE.LOG (only use this option
- when running the test from a floppy, since hard
- disk data corruption will occur!!!)
- The old WDAT_IDE.LOG will be overwritten.
- S = skip pause at end of 'no menu' run
- R = relocate sectors marked as 'bad sectors'
- F = relocate addresses shown in file WDAT_IDE.DAT
- D = operate on second drive if F option chosen
- 1 = select first drive, run quick scan with no menu
- or C option
- 2 = select second drive, run quick scan with no menu
- or C option
- C = comprehensive analysis, no menu. used with
- options 1 or 2
-
- The 'L' option may be used at anytime with the above line
- options. It will show the drive ID information and any error
- that occurs. The old WDAT_IDE.LOG will be overwritten.
-
-
- The data file for the 'F' option should be an ASCII text file
- with a C, H and S specified for each address to be relocated.
- To relocate a track, specify the C and H and set the S to
- 255. All addresses must be specified in decimal. All sector
- addresses are for user locations. All track addresses are
- physical locations. The first sector is specified as one,
- not zero.
-
- For example, to relocate the TRANSLATED 23rd sector from
- index at C10 H1 and the NATIVE track at C20 H3, store the
- following text in WDAT_IDE.DAT:
-
-
- 10, 1, 23
- 20, 3, 255
-
-
-
- PROGRAM CHARACTERISTICS:
-
- - retries disabled
- - cache disabled
- - identifies drive models and number of drives
- - menu driven
-
-
- MENU OPTION DESCRIPTIONS:
-
- MAIN MENU SELECTION:
-
- 0 - Quick Surface Scan
- 1 - Comprehensive Analysis
- 2 - Performance Data
- 3 - Select Drive
- 4 - List of WD drives
- 5 - Help
- 6 - Park Drives and Quit"
-
-
- MENU SELECTION "0 - Quick Surface Scan" description:
-
- 1. Read sequentially, a track at a time. No
- writes are issued.
-
- 2. Performs appropriate defect management if errors
- are detected: See section below for details
- regarding defect management.
-
- 3. Will save user data when conditions permit. Some
- conditions will not allow the customer data to be
- retrieved.
-
-
- MENU SELECTION "1 - Comprehensive Analysis" description:
-
- 1. Prompts user before starting that data will be
- lost, ESCAPE to exit.
-
- 2. Read scan of surface first as in selection zero
- above.
-
- 3. Writes/Read sequentially, the entire surface a
- track at a time. Each track is written with 9
- data patterns, and 10 reads are issued after each
- write. So each track is read a minimum of 90 times,
- more if errors occur. The data patterns are:
-
- PATTERN:
-
- A: 0031304dc3bad57bc44b75602e358da99986c947dbb0
- B: 6633
- C: 33cb
- D: cb4cf730
- E: 2222
- F: 136b31136bb3
- G: c086043021800
- H: random data
- I: 0000
-
- 4. Performs appropriate defect management: See
- section below for details regarding defect
- management.
-
- 5. Will not save user data, this selection WILL
- DESTROY all customer data.
-
-
- MENU SELECTION "2 - Performance Data" description:
-
- 1. Data collected will be displayed based on drive
- selected.
-
- 2. If no drive is selected or not accessable the
- message 'Can't establish physical parameters'
- will be displayed.
-
- 3. The following data will be displayed. If the
- L option is selected it will be logged:
-
- Track to Track SEEK: shown in milliseconds.
-
- Average random SEEK: shown in milliseconds.
-
- Full stroke SEEK: shown in milliseconds.
-
- DATA transfer TEST: B: = block size, data
- shown in kilobytes/sec.
-
- 4. This selection is not restricted to drive list
- maintained by this program.
-
-
- MENU SELECTION "3 - Select Drive" description:
-
- 1. Prompts user to enter 0, 1, or ESCAPE to exit.
-
- 2. If drive is present the Model number, Serial
- number, Firmware and Cylinder/Heads/Sector per-
- track, will be displayed under the corresponding
- DRIVE NUMBER.
-
- 3. If drive a is entered but not accessable, the
- information in 2 above will be replaced with
- 'DID NOT RESPOND', the bottom window will show
- 'NO drive is SELECTED'.
-
- 4. If a drive is selected and accessable the drive
- number in the top window will blink and bottom
- window will show 'DRIVE # is SELECTED'. If the
- L option is selected the information in 2 above
- will be logged.
-
- 5. This selection is not restricted to drive list
- maintained by this program.
-
-
- DEFECT MANAGEMENT DETAILS:
-
- If an error is detected while reading a track, the following
- steps occur:
-
- 1) If a Bad Block error is detected, then the sector is
- re-formatted as no longer bad. If R option sector will
- be relocated.
-
- 2) If an error occurs during any read, the relocation
- algorithm is executed, and reverification of the
- track is repeated.
-
-
- Relocation Algorithm Details:
-
- If a servo error occurs, the track is relocated.
- If an ID Not Found error occurs, the sector is relocated.
- If a physical track already has 3 relocated sectors, the
- track is relocated.
- If an ECC or DAM error occurs, the sector is relocated.
- Since retries are disabled, correctable ECC errors are
- reported as uncorrectable and are relocated.
