SCSI hard drive is not used by common PC users but used in some special fields such as audio recording, video editing, web servers, media streaming servers, gaming systems.
The following is one SCSI hard drive opened in clean room environment which has a capacity of 4.3GB and 12 platters and 80 pins. It is 80-Pin SCA-2 SCSI hard drives / Discs / Disks (Hot Swap) for servers with hot-pluggable back-planes.We seldom find such kind of drives now and therefore post it for sharing: Read more
We have handled many WD PCB1692 series 2.5″ hard drives with some tips entering the safe mode.
For 2.5″ PCB1692 or series after, it’s not a problem to read ROM when the hard drives are recognized. But it’s a problem when we tried to write ROM and it’s quite often to make the PCB dead by writing ROM to it.
The success rate is not high to enter safe mode by short connecting on 1692 series. The best way to enter safe mode for 1692 series is to separate the PCB, anyway, pls don’t remove the PCB.
Users just need to remove the two screws on the PCB to control the heads contact and insert one biz card and then power on and wait until the motor stops spinning and then the hdd enters kernel mode and next the ROM can be read and written.This also helps to read firmware modules for some hard drives with bad heads.

When users are going to replace heads or platters in a clean room environment to get the lost data back, it’s a must for these users to learn about each physical component what it is and how they work.
Today let’s check some of the most important physical components: Heads, Platters, PCB.
The platters contains the data and the heads contains read heads and write heads to read data from platters and write data to the platters. PCB is another very important physical component, it contains not only some of the firmware codes like ROM, but also controls the electrical components to offer power to the hard drive running.

When we are talking about dead hard drives, we usually refer to those which doesn’t spin up at all, no hdd working sounds, no response and they look dead. Actually some of these so-called dead hard drives are still alive and these drives can be still repaired and recovered.
If the driver IC is burnt, the PCB won’t power up at all, users can swap with one donor driver IC or swap the whole PCB with original ROM/bios chip transferred;
If the PCB is burnt or other electrical components of hard drives are burnt, the hard drives won’t be powered on and won’t spin up at all. At this time, users just need to find one compatible PCB with the same PCB number from the same family and put on the dead hard drives and then manage to regenerate the original ROM to recover the data;
If the motor of the dead hard drives is stuck, users need to disassemble the hard drives and remove the platters to a donor hard drive to read data from.
