Case:The customer’s storage medium is an 8G memory card. When a card reader is inserted into the computer, it is found that the data of the memory card was lost, and other operations were not performed afterwards. After testing by the North Asian Data Recovery Center, it was caused by the invasion of the virus….
How to check if a partition is aligned?
Seagate has created a simple Windows utility, Partition Offset Information, to read and display the starting LBA for every partition. This tool can analyze the starting sector of a partition if it is misaligned or not.
In the example below, drive C: is a generic drive (ST9160823AS) with 512 bytes per sector. Drives F:, G: and H: are logical drives, all on the ST32000540AS which has a 4096 byte (4KiB) sector size and an Alignment of 0.
If the alignment on the ST32000540AS was 1, instead of 0, the display would look like this:
Notice: the the RED exclamation marks. These marks indicate that the Logical Volumes (drive letters) in this partitioning arrangement are not aligned with the physical sectors on the disk drive. Normal 4K disk drives will ship with Alignment 0. Drives with Alignment 1 and not typical and the example above is shown only for comparison purposes.
It is important to understand that the drive operates with the same reliability, but just a little bit slower when WRITING to the drive. It runs the same when READING which accounts for the majority of activity on a disk drive.

Case:When the mobile hard disk is in use, it is accidentally unplugged from the computer. The entire folder of the computer is gone. About 500MB of CAD data needs to be recovered. Solution:The engineer was determined that there was no cover after testing, and the virus destruction was also ruled out, and the recovery software…
I have worked with dozens of consumer grade WiFi routers, and they have been really hit-or-miss with this, though it seems to be getting better. Example of issue: A device that can be discovered with mDNS is connected into the router with a cable. Another device connected to the router on WiFi attempts to discover…

This tutorial is not for inexperienced users!!! Do NOT POWER OFF YOUR hdd, computer, during it, (EXCEPT IF I SAY SO)and you just to be sure connect your computer to UPS.
First you must have to build serial rs232 converter to TX,RX GND, you can use any data cable from your cell phone from Siemens 35 series custom build data cable buid on this picture with max232. Be sure that you put zener diode 2V7 at the picture..Because you could burn your Tx, Rx, on HDD-s PCB.
So, when you build, get your adapter, connect it to this pins on Seagate drive.
[ ”””””””’| |””””’ ] [ .. ..] —-> Rx.. Tx
You do not need to connect SERIAL-ATA CABEL
open hyper terminal or another type of terminal select Serial port example “COM1”
set bit rate to 38400bps
data bits 8
parity N
stop bits 1
it’s default settings except bps.
plug power to disk and after that you will see on terminal something like this:
PART 1
Rst 0x10M
hit Ctrl + Z to get “prompt”
F3 T>
now, if your BIOS recognize disk but there is 0 LBA,0 capacity
all you need is to hit this command:
F3 T>m0,2,2,0,0,0,0,22 Enter
!!!IMPORTANT, don’t turn hdd power off, or comp off, wait about 30 sec to 2 minutes until it finished!!!
then you see something like this.
Max Wr Retries = 00, Max Rd Retries = 00, Max ECC T-Level = 14, Max Certify Rewrite Retries = 00C8 Max retries Wr = 00, Max Rd retries = 00, Max T-ECC Level = 14, Max certify Rewrite retries = 00C8
User Partition Format 10% complete, Zone 00, Pass 00, LBA 00004339, Err Code 00000080, Elapsed Time 0 minutes 05 seconds User Partition Format 10% complete, Zone 00, Pass 00, LBA 00004339, Err Code 00000080, Elapsed Time 0 minutes 05 seconds
User Partition Format Successful – Elapsed Time 0 minutes 05 seconds User Partition Successful Format – Elapsed Time 0 minutes 05 seconds
After that hit
F3 T>/2
and
F3 2>Z
Spin Down Complete
Elapsed Time 3.038 msecs
Turn off power from your HDD, od shutdown your computer.
WARNING: Please do NOT try this if you have valuable data on your drive. Do not blame anyone if something goes wrong. You do it at your own risk. Remember that if something goes wrong, it is extremely unlikely that anyone will be able to help you remotely. One wrong command via terminal could easily result in a completely bricked HDD (I really do mean bricked = no one will be able to recover it, even Seagate).

Modern hard disk drives use one of two interfaces: IDE (ATA) – Integrated Drive Electronics (also called ST506 drives) and its variants (EIDE – Enhanced Integrated Drive Electronics, or the SCSI (Small Computer System Interface). You can tell immediately by looking at the back of the hard disk which interface is being used.
1. IDE hard disks use a 40-pin connector, and SCSI hard disks normally use either a 50-pin or a 68-pin or 80-Pin connector.
2. Note: Older MFM (MODIFIED FREQUENCY MODULATION), RLL (RUN LENGTH KIMITED) and ESDI (ENHANCED SYSTEM DEVICE INTERFACE) hard disks used two data connectors, one 34 pins and the other 20 pins.
3. The cable usually has a red stripe to indicate wire #1 and the hard disk uses markers to indicate the matching pin #1.
Led Connector: Originally, hard disks shipped with a faceplate (or bezel) on the front. The hard disk was mounted into an external hard drive bay (in place of a floppy disk drive) and an LED was visible on the front of the drive to indicate when the disk was in use. It was quickly realized that having the disks mounted internally to the case made more sense, but the LED was still desirable. So an LED was mounted to the case and a wire run to a two-pin connector on the hard disk itself. On newer systems that run with integrated IDE controllers on the motherboard, the LED is connected to a special connector on the motherboard itself.
Drive Bay: The entire hard disk is mounted into a physical enclosure designed to protect it and also keep its internal environment sealed from the outside air. This is necessary because of the requirement of keeping the internal environment free of dust and other contamination that could get between the read/write heads and the platters over which they float, and possibly lead to head crashes.
DRIVE BAYS are where internal hard drives are mounted inside the PC. They come in internal and external versions, based on whether they allow access from the exterior of the case, and also in two standard sizes: 5.25″ and 3.5″.
Now, we have rough understanding of the HDD components now and how these parts work in architecture. But you may find the importance of the microprogram inside the HDD. No matter how precise the HDD design, they are a stack of meaningless mechanical parts.
