WD for amending the law

WD amending the law of the circuit board in the BIOS: A 29. suffix BIN> PC3000 support direct moment; B 27. suffix LMC> PC3000 does not support the moment, the solution: one with 61 # module, change the name suffix To 61LMC (boot files); 2 replaced 29 of the BIOS to brush writing.
. Circuit board to pay attention to a few: 1 5V, 12V for the driver IC; 2 motor ports, four high above 5V waveform; 3 BIOS easily broken (missing); four master chip easily broken (blank welding); 5 cache has four legs, the second pin low waveform.
PC3000 WD menu experience, (G table is 0, the hard disk is normal)
1. Firmware zone option (equivalent to service zones and reserved zones) ( "a" reserve; "2" to change the compiler (eg: overall SSS reconstruction of GP tables; bad form to write the firmware GP; ③ negative Road bad (MODEL ID after "-" no) "cylindrical bad; PCI, the efficiency of the source data -0-32 offset the negative track. which only used -0-9);" 3 "motor stop switch, hot and Exchange.); 2. Disk Information (overwrite capacity); 3. Internal Low Grid (repair bad sectors <XXX SSS>); 4. Logical Scan (in the HRT, PCI can repair a small amount of bad sectors); 5.SMART Table option; 6. defect menu option (G switch P); 7.SF (PC3000 invalid, PCI effective and efficient source of good results); 8. exit.

2. The main issue: 1. Negative Road or bad, can not rebuild GP table; not lower grid (if necessary, make good use of disk backup); 2. Brush to write BIOS. With special software brushes; 3. Bad sectors so weak Road, SF, with PCI, the efficiency of the source; 4. bad sectors repair bad moments off section; 5. repair bad sectors reconstruction GP form can be multi-SSSS; 6. Safe Mode (: lll), only to write the circuit board; 7. knock plate involved to the circuit board and BIOS
3. Revised negative Road Process (Note: Western Digital is not necessarily done in): write not allowed to write negative Road, clear the negative channel data, write, no, to offset the bad track. You can write, not really. Guan head Guan Duan.

2 20 #, 21 #, 22 #, 23 #, 25 #) is a decoding table module, if bad, undetectable LBA value, and knock on disk, do not recognize disk instability, 25 # usually bad.
1 17 #, 18 #, 5A #, 5B #, BF #) is a sector of the table module.
26 #, 29 #, 2A #, 2B #, 2C #, 2D #, 2E #, 2F #) is a SMART Table module, namely, the protection program, if the bad instability (often bad).
46 #, 48 #, 49 #, 4A #, 4B #, 4C #, C5 #, C4 #) is a calibration parameter, if bad, does not recognize disk, knock on disk, slow disk recognition.
4E # = ROM firmware version number 61 # = boot procedures for the brush to write flash rom FF # = self-test module EX, FX = reservation?
41 # = modules directory, the location of the module firmware zone table (used for offset) 42 # = Configuration Table (hard disk ID)
43 # = P in Table 44 # = G table (zero on the OK)

WD hard drive is the BIOS control the head, for board for BIOS can brush writing. WD safe mode (: lll), motor does not turn, the hard disk does not work, the role of moments and brush BIOS, only supports W29F moment, the moment does not support the W27F . Note: In Safe Mode, the brush to write BIOS to add a * LMC file. brush W27F BIOS, the 61 # module generates REN file, change the file extension LMC boot brush to write.
WD explain the relationship between the modules
<1>61#,01#,02#,10#,11#,12#,14# ,19#,36#
"1" 61 #, 01 #, 02 #, 10 #, 11 #, 12 #, 14 #, 19 #, 36 # for the boot file (ATA micro-code modules, similar to the Maxtor 39 #, 38 #, 4F #) ;
61 # is to guide the procedures for the brush to write flash Rom Bios;
<2> 26 #, 29 #, 2A #, 2B #, 2C #, 2D #, 2E #, 2F # for the SMART module documents, 29 #, 2D # (usually bad) is the parameter module, 2A #, 2B # , 2C # is the log module, 2E #, 2F #'s role is to initialize SMART parameters.
"3" 41 # is the module directory (modules recorded the firmware zone location, length size information).
42 # is the Configuration Table Module (SN recorded numbers, passwords, type, ID and other information)
43 # is a P table, 44 # is a G table, 4E is the ROM version number (the hard disk firmware version number)
<4> 46 #, 48 #, 49 #, 4A #, 4B #, 4C #, C4 # for the calibration parameters are automatically generated when the self-test, if the bad does not recognize disk; FF # is a calibration module;

WD's summary:

1. Recognize disk: bad sectors weak Road, red and green chunks sssxxx: <1> sss internal low-grid, write firmware, G, P table, reconstruction compiler; "2" negative Road, or bad, low-grid to write a negative Road, No, with PCI, the efficiency of the source offset;
Do not recognize disk: "a" circuit board (BIOS); <2> negative Road is intact; "3" firmware area is good;
3. Knock on disk: "a" circuit board, Bios, Rom damage; "2" head offset; "3" head or a bad disc; "4" firmware zone bad, the negative Road District, the bad (formatted solving).
