Friends, the topic is this. On the laptop a blue screen. I put a LiveCD with Windows 7 quietly loading, it works, but .. does not open the C and D sections of the system hard drive. When you click on drive C simply does not open it. When you click on the disk, D says "Disk is unformatted." Do not run any programs with Live CDI, too, do not see partitions D and C. Is it possible for me to go buy a new HDD?
I can not lay out screenshots, I will answer any additional ones. or leading questions. Launched another CDI with Akroniks, he sees only the sizes of volumes C and D, however, he also can not do any operations.

No running CDI programs can also see sections D and C
And what shows a SMART disk from the same LiveCD? It is necessary to decide whether this is a software problem or a hardware problem.

ivan govorov,
The thing is. There are bad sectors on the hard drive + the file table has flown (possibly due to damage). You can do it as a user, to launch hdd regenerator 2011. It can extend the life of the disk a bit by transferring links to bad sectors to the backup area of ​​the disk.At the end of the actions they (!), Will have to decide - whether the data on the disc or not. If necessary, you should think about what they are likely to be lost due to damage and spent on the restoration time can be wasted. Increase the chances of recovery itself can be explored console program testdisk. Namely, it functions restore the partition table and the file table. If you do not want - to make the removal of all the partitions, then create them again and make their full format. After completion of the above-described drive operation will be used again.

I hope you had backups of your files and you respect backups at least once a week. If not, I hope that this case will teach you how to back up.

P.S.
Just restoring another hard drive. So what the hdd regenetor looks like you already know. I want to note that the program takes a very long time to recover. In my case, 2,300 sectors were recovered in almost 16 hours. A broken sectors can be 50,000, and 70,000 and 100,000. That is "recovery" may take days.

tempico,
understood, thank you. Data is not needed, the moped is not mine. Today I turned on this laptop, and - what the hell ... I have stopped loading all the LiveCD. In general, sit down, and as a result, instead of the booted system, I see a black screen with a white mouse cursor. What could I do wrong?
Hmm, that’s what I’ve done right now. I inserted a suspicious HDD into another working laptop. Included. Immediately writes: SMART Failure predicted on hard disc 0: the name of the disk. Launched from under the shower sit the acronis. Deleted all volumes and formatted. In 15 minutes of operation, the hdd is heated so that tea can be boiled. It seems to him all the same Khan. Now I will insert hdd into his native laptop, I'll try to roll Windows.

update: I started installing Windows, immediately writes: "Installation to this drive is not possible. Perhaps the drive will be damaged soon." But still started to install. Then everything is knurled. Thanks for the help!



Rep: (1161)
ivan govorov,
In that case, I would not risk using this disk. A malfunction on the hard drive board created due to overheating can damage the chipset of the laptop motherboard. When burning chips, really random things happen. And here two devices are connected directly by one wire and the Chinese quality mark.

I hope that the laptop user is lucky and everything will be more or less good.

I did not fix it on the case, but simply put it on the piece of iron neatly .... I noticed for a long time that the case beats electric current ... the case is somehow shaken and he moved the board to the piece of iron and punched him.
Is it being treated? How expensive?
On the screw itself, nevermind, the main files on it.

No. To the scrap.

And you - read safety precautions and give hand in hand. Sistemnik could catch fire at any time. At least because of short circuit. In BP, the currents are not children's. 20 amperes each. If you don’t care, you don’t need to substitute your relatives.

It is treated. Expensive.
At the native conference you ask (or google) the contacts of the person / office that is engaged in data recovery in your city. They will take money from you for a donor + work. The higher the probability of recovery is called, the more money will be taken. Something like this...

Good day!)) Trouble, comrades !!! I inserted an external hard drive into the USB smart TV (LG), paused while watching the channels from the antenna, he wrote something and suggested “yes / no” ... Without reading the message, I press “yes” and that’s it ... HDD is not identified, writes me a tv. Comp defines it through computer control, what to do with it, I do not know. Attention, the question is: how to restore the product’s performance and at the same time save 900 GB of information? Hard WD My Passport 1 TB.

* nik5075,
Ah, well it’s not so scary. There are options.
99.9% working option to save information:
Run testdisk, disable logging. Select the disk to 1TB, the type of partition intel, press analysis, then load backup (keep your eyes peeled tips at the bottom, L button). Most likely there is a valid backup of the table. Press P (keep your eyes peeled over the tips) to preview files - if you know your files - excellent! This means the backup that is needed. Keep a backup of the table as the original it (the program will tell which button to press, probably W). If a backup is not the - looking at each copy of the table, without the need for confidence and "W" will not reap. If there is no - will have to start in-depth analysis. But practice shows that this problem is eliminated from the first time, the first backup, a minute and a half. Recovery algorithm FS table is similar, just on the list will be added "more copies."
After writing the changes to the disk, wait 20 seconds, then simply pull it out without safely removing it. Windows likes to write all sorts of nonsense on the disk when removing. If the operation will be done under Linux (I recommend this option, but do not insist), then it is advisable to write to the console before extractingsyncto synchronize buffers and storage devices, and only then do physical extraction.
If you are afraid to do a full recovery, you worry that you will click the wrong button .. then at the time of viewing the list of files (P) you can restore the necessary files by pressing C (copy files from damaged device) and choosing the directory where these restored files will be copied (of course the directory should NOT be on the "damaged" disk, but, for example, on the system disk of the computer).
If the disk starts to determine all the files again, do a disk check (check disk), without checking the free space.

95% working option:
If you still don’t understand anything: start (as administrator) R-Studio, which I gave above, click "scan", then in the scan results you can pull out files and directories. But they can be wildly scattered, so you have to be extremely careful. But the interface will be graphic, with a bunch of beautiful buttons.

50% option:
Download Recuva. The master will clearly describe everything. Recovery will be long, file names will be lost, the directory structure will be destroyed. The data will be restored, but it will take a lot of time to process it.

0% data recovery:
Format the drive and just use it as a new, if purchased at the store. It will be a good lesson. If the data were really needed - would be back up to half an hour could be returned back to the disk. Restoring files, of course, it is good practice, but you should understand that the program for the recovery - is not a panacea and does not replace regular backups. It is an expensive operation (especially in the corporate sector), in which no one can give guarantees.

-1%
Maybe someone will advise some other programs that restore information in 1 click. Of course you can try. But keep in mind that in manual mode you at least know what the program can do. In automatic, it can destroy data.

I don’t know what topic to write if you don’t quarrel.
I dropped my hard drive yesterday, when I connected, the computer first saw it, but didn’t open it - it required to be formatted. I did not, I pulled out the cable, reconnected, the computer did not see it at all.
Actually the question is, is the disk amenable to repair? and will it be possible to recover information?
