To understand how works IDE interface of an hard disk - Le but est de comprendre comment fonctionne l'interface IDE d'un disque dur.
Main components of this hard disk are:- Binary content of the 32Kb Eprom 27C256 W3.4 Firmware / Le dump de l'eprom 27C256 révision W3.4 (PLCC32 rect.) est donné dans le fichier suivant : shd3062a.bin Shift-Cliquer pour télécharger (32 Ko).
- source of the firmware Version W3.4 disassembled with XDASM / Le programme source 68HC11 à l'état actuel désassemblé brut est donné dans le fichier: shd3062a.src Shift-Cliquer pour télécharger (600 Ko).
* Pour le mettre en MASTER : mettre les cavaliers C/D et DSP
* Pour le mettre en ESCLAVE (SLAVE): mettre uniquement le cavalier DSP.
Dans les 2 cas le cavalier ACT près du connecteur IDE doit être
mis.
* to put the drive in MASTER : jumpers C/D & DSP must be placed
* to put the drive in SLAVE : only fix the DSP jumper
* in both cases jumper ACT must be in.

- De même si vous disposez de disques durs utilisant le circuit AIC6060Q d'adaptec, celà peut etre intéressant de faire des comparaisons.

My drive probably has many bad sectors. We can see this with a SMART tool such as CrystalDiskInfo.
https://crystalmark.info/en/software/crystaldiskinfo/
There is not much we can do in this case with ordinary tools and techniques. Sometimes we can refurbish the drive by disabling a bad head and applying a factory "burn-in" procedure.
I may be able to dump the drive's firmware modules (and ROM?) with the demo version of SHT or SHTR. These can be downloaded from The HDD Oracle
http://www.hddoracle.com/viewforum.php?f=149
Note that defect lists and SMART data are just some of the firmware modules that are stored on the Maintenance Cylinders (MC) on the platters, not on the PCB. It would be interesting if we could dump the EPROM.
Franc has written a couple of primers to help people to understand the firmware architecture of HDDs. hope you find them useful.
