Damn, the files weren't backed up and got deleted!

Damn, virus infection!! CIH infection, file errors!!

Damn, the disk was quick-formatted by mistake!!!

Damn, the information in the master boot sector is damaged!!!!…

What to do??? If you go to a repair company to fix it, not only does it cost money, it also takes effort, and you also have to worry about the possible losses caused by missing files. If you run into one of those big-name companies and they politely say they don't have the technical ability, I think I'd faint.
Don't worry, I have FinalData. Even though I don't understand DOS, don't understand clusters or sectors, I can handle it myself.
FinalData 1.0 Chinese-localized trial version: (for IBM PC compatibles running Windows95/98)
Download address: http://go.163.com/~sons/soft/fd.zip 1MB in size
Original version: Because there are all kinds of operating systems, Linux, OS/2, NT…, and their disk partition formats are all different, you can go to www.alphaomega.co.jp/finaldata/
and find the recovery tool suitable for your own operating system — the FinalData trial version.
Operating environment
* PC/AT compatible
* Windows 95/98
* 8MB or more memory (16MB or more recommended)
* Standard installation requires more than 45MB of hard disk space
* Minimum installation requires more than 35MB of hard disk space
* 2x speed or faster CD-ROM drive (the standard version of FinalData is sold on CD)
* VGA resolution with 256 colors or more
The Chinese-localization package only needs to be extracted, no installation required, and it can be used right away. Let's begin our search journey. For this, I deliberately quick-formatted one of my partitions. Open FinalData.exe, and just by looking at the icon, you can tell it's a disk doctor, for emergency lifesaving. The startup interface is very simple, a standard Windows program interface. Select "Open" from the "File" menu, and you need to choose the logical partition where the files you deleted were located. The files I deleted were in Disk F. As for which cluster or sector that file was in just now, I haven't the slightest idea, so I simply searched the whole partition from beginning to end. That can't go wrong. This search time depends on the size of the hard disk partition; anyway, mine was very fast. If you know enough, reasonably adjusting this search range will make it even more efficient. No need even to get drowsy—look, all the files that were just formatted are displayed, including boot sector information and so on. A lot of them are formats I don't recognize, but never mind that. In the right-side window, just select all. (Unfortunately, the trial version only allows you to recover 3 files, so you'd better make good use of that.)
Then choose "Recover Save" on the toolbar, or choose it from "File" in the menu, and select the path where you now want to save the recovered files. Then press the "Save" button.
Like other Japanese software, FinalData also carries through the traits of simple operation, practicality, and high efficiency. It really is very good software. Below I'll tell everyone some of my experience from using the Chinese-localized version.
1. Do not install FinalData in the partition containing the damaged files. I suggest "praying only when the Buddha's feet are already in sight"—if you discover mistakenly deleted files that need recovery, then go install it. Therefore, if your large hard disk is not partitioned, that is very unwise. Also, it's best not to write new files to the partition where files were deleted.
2. If Windows can no longer boot, it's best to prepare another hard disk, or borrow one from a friend, install FinalData on it, and handle the hard disk that needs repair as a slave drive. This situation is fairly common for multi-system users and for people for whom reinstalling the system is very inconvenient.
3. No matter what storage device it is, it can be recovered. Floppies, even my MO and ZIP.
4. DIY. Easy to operate, no need to understand DOS commands, no need to install backup software beforehand; no need to find a professional company, and it's safer. If your files contain extremely confidential material, are you not afraid of letting others know?
5. Everyone can understand that in windows, even though a file is deleted from the Recycle Bin, it hasn't actually disappeared from the disk. Of course Windows itself cannot recover it, and FinalData makes use of the characteristics of how data remains on the disk. It not only recovers mistakenly deleted files, but has even stronger functions as well. It can also recover quite a few files damaged by virus infection. I've only tested recovery of virus-damaged files a little; things like CIH and Word macro viruses can be recovered. As for others, that awaits everyone's verification.
6. If your disk has a lot of fragmentation, it will cause trouble for recovery, and the number of files that can be recovered will be reduced. So it pays to be conscientious in daily use; regularly defragmenting the hard disk will be of great benefit.
7. If the hard disk has physical damage, then don't place any hopes on FinalData. So I strongly recommend that you install FinalData while your hard disk can still do its utmost for you. Emotionally speaking, I hope you never have a day when even FinalData can't handle it.
8. Please keep an eye on my homepage --- "The Peacock Flies Southeast" http://mago.yeah.net , because a cracked Chinese-localized standard version will be released soon. But at the same time, I regret that although FinalData has released corresponding versions for all kinds of systems, the only thing we can find online is the Windows trial version. I downloaded the standard version using my own Japanese bank account. So I hope you will cherish it.

One of my drives was also formatted by mistake, and the files on it are very important too, but the commands above don't seem to work. Now when I open it, it says it is unformatted. Under DOS, when I use CHKDSK, it says the format is RAW and unusable. What is going on here?

The following is quoted from 覆水难收's post on 2003-7-10 11:25:21:
Today I was installing the system, and while doing FORMAT, I accidentally formatted drive D. There are important company files in it.
If the BOSS finds out, I'm done for,
Which expert can tell me how to recover it
Please save me...............


A few suggestions:
  1. If you have not performed any write operations to drive D after formatting it, and you did not use the /U parameter when formatting drive D, then congratulations, you still have a chance to recover the data;
  2. If your drive D uses the FAT16 format, you can choose to use the UNFORMAT program from Norton Utilities or the UNFORMAT program in the latest versions of DOS to perform the data recovery operation;
  3. If your drive D uses the FAT32 format, you can first install WINDOWS on drive C, then install a WINDOWS version anti-format software tool, and then recover drive D;
  3. If your drive D uses the NTFS format, then you need to install a data recovery tool under XP to recover the data;
  4. If your drive D is ...... (I also don't know what to do then)

  If anything is inappropriate, please correct me.
