English translation of ZU readme.txtThe previous release of ZU (ZU.Betta1.1) used simple methods to remove passwords.
Removing the passwords on HGST/IBM and Native Hitachi HDDs (eg _DK23DA, _DK23FA ..) requires that they be placed in so-called "SafeMode".
ZU.Betta 2.0 now supports working in this mode.
Since different drives require different amounts of time to enter this special mode (eg Native Hitachi HDDs require up to 2 minutes), now, for the sake of convenience, a timer is started when ZU is launched. The program reports the elapsed time at one second intervals, for example ELAPSED 00:00:22 (00:00:23 ..), while concurrently conducting a survey of readiness on the specified channel. Press any key to stop this polling if it continues for an excessively long time. The program will then terminate with the message "UNLOCK NOT DONE".
To distinguish between vendors, there are now 2 qualifiers:
Code:
"." for HGST / IBM
"8" for Native Hitachi
That is, one would use command formats such as the following:
Code:
ZU / S. battle with HGST on the Secondary channel :)
ZU / P8 NativeHitachi on Primary channel
Placing the drive in SafeMode can be done using a variety of methods.
HGST PATA models can simply be jumpered for SafeMode, while other drives can be induced into SafeMode by "faulting" the NVRAM or by shorting specific points on the PCB.
In general, one can simply try to apply power to the controller while it is disconnected from the HDA (or unscrew the 2 screws on the controller on the side opposite the interface and slightly lift it with a toothpick

)
After ZU detects the drive and attacks it, the program will report the NativeHitachi message "NOW YOU CAN SCREW IT IN. PRESS ANY KEY WHEN READY".
The HGST message will be "POWER OFF / ON AND EXECUTE ZU AGAIN".
In the first case, you just need to reinstall the controller on the drive, carefully screw it down, and then press any key.
In the second case, turn off the power and reinstall the controller. Then power up the HDD and run ZU again with the same parameters. This procedure applies to IBM / HGST (ExcelStore) models from DTLA to HTS7225xxK9SA00 (5K250) (dozens of models).
The following are not supported:
Notebook HDDs with suffix A300 (A301) (eg 5K500 B-250 HTS545025B9A300)
(blue controller with 9 screws)
3.5" HDDs with suffixes 332/362. (eg HDS721010CLA332, HTS721032CLA362 ..)
[These will be supported as soon as there is a sufficient number for experimentation.]
P.S. Fixed bug for Samsung Rubicon.
