Undetected hdds can be caused by many reasons such as ROM damage, SA module damage,  incompatible SA and ROM, head damage, etc. This case study is to teach the ROM and SA must match by having the same microcode.

The hdd was undetected due to ROM damage and let’s now analyze and follow some steps to fix it.

For hard drives of all hdd brands, if they are encrypted by ATA password, they are usually full of exclamatory marks when you try to scan them by MHDD and users are warned about PWD telling the hdd is locked.

Due to the special design of hitachi hard drives which have three copies of firmware, copy 1, copy 2 and a backup copy of firmware. After the hard drive is encrypted, the working zones of firmware copies are protected, the NVRAM cannot be edited too. Anyway, the contents of the NVRAM are not affected and the factory firmware copy is not protected.

For Hitachi hard drives, they can be ready by connecting the PCB alone. Users need to have some tools to enter the firmware backup copy, read the password module within this copy and write it to the copy 1. If the password module of backup copy is damaged, users need to find a donor password module of the same series of hdd to write. After this module write, the password is usually removed. Read more →
