様様様様様様様様様様README - WDAT_IDE.TXT様様様様様様様様様様 REVISION: 3.5 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.
