I need help to recover information of Hitachi HDS721010CLA33

[hibrid0]

Hi guys, I need help to recover my information from Hitachi HDS721010CLA332.

I used in this HDD Regenerator ( ), and this software can´t continue around 597MB sector 1180000.

I use FileScanveger and get some files ( ) 200MB, but I need get more information.
I try with R-studio and say cyclic redundancy error.
This is the log:

I need this information, please helpme.
I have R-Studio, Stellar Phoenix Data Recovery, FileScavenger.

This disk is 1TB, and I have other disk of 1 TB but I cant create a image , any suggestions to try to create a part of image arround only 200GB of information saved in the disk dead.

Windows Kwnow the disk and I can acces, but only show some FOUNDXXXX, yeah Chkdsk, but not me....

[hibrid0]

Any idea to try to recover with software?
or is needed tampertred? I haven´t experience opened hard drives.

Please tell me more about open disk I have some bad disk to learn

[Nick_CT]

Do not open or tamper with the hard drive, you will only make the problem worse.

If you want to try and image it you can research a linux tool called GNU ddrescue, it handles disks with bad areas quite well.
http://www.gnu.org/s/ddrescue/ddrescue.html

If you don't want to risk the data or make things possibly worse then contact a professional data recovery company.

[hibrid0]

Okay guys, I have now Ubuntu Recue Remix with DDrescue.

I´m learnig about this software, but anybody with experience in that to tell more suggestions how to use it nad tricks.

1TB I need recover this information to my Boss at the monday.

I have an other disk to save the information of 1TB and I cant create a full image.

How Can I create an image of part of the disk arround 800GB is possible, the disk are used 180GB when that´s worked fine...

Sorry guys for my english, I hope understand here.

[Nick_CT]

I've only ever used it to make a full image, not a partial one. From what I remember it's fairly basic to use:

ddrescue /dev/sda /dev/sdb (That's to image HDD sda to HDD sdb) and off you go.

You should probably read the help documentation and tutorial first, don't take my word for it. Make sure you get the drive listing correct, if you make a mistake there you can overwrite the wrong HDD and lose all your data.

Use fdisk -l to see what drive is what.

Maybe do a practice run first. Be careful, putting more strain on the drive could make the problem worse. If you really want your best shot at getting the data then take it to a professional. But if you want to try yourself then good luck. Once you've made an image then you can use your other software R-Studio on the imaged drive.

Hey thanks for your quick answers.

I go to it!

1TB I need recover this information to my Boss at the monday.

If you try DIY, then you might be lucky - or you might make the problem harder for a DR company to recover the data, if you fail, or you might even destroy your own data. You must prepare yourself that you may not be able to recover the data by Monday.

I suggest that you keep any blocks which you have already read successfully from that disk, in a safe place somewhere (you seem to mention different figures for the amount you have already recovered - 200MB? 180GB? 200GB? it's not clear to me...) . Depending on exactly how you already read that data, you could actually merge that into the ddrescue output without needing to read it again, if you are experienced with Linux, and if you know exactly which blocks were read successfully.

With great respect to Nick_CT, his suggested command line is missing the use of the ddrescue log file, which is one of its more useful features - so while that command line would work for one type of clone attempt between the two stated Linux disks, IMHO it is not optimal. (Sorry Nick)

As Nick suggested to you, if you really want to try that ddrescue utility (which is what I have used for (non-professional) DR, but it is not "1 click" software), you need to read its online manual and some of the tutorials which you will find on the web, written by other users - and make sure you understand them, before you do anything with your disk! There are many different options in ddrescue which can be changed to try to recover data, but there is no "correct" set of options, which is best for every case - you need time, skill and experience to see what is happening during your clone, and decide which approach is working and which approach is not working, as the cloning progresses. Due to the language difficulties here, it is not sensible for me to make further detailed suggestions.

No apology necessary, log file is indeed very important. It's been an age since I last used it

Hi Vulcano.
The damaged Disk 1TB Hitachi.
Recovered information on Windows 200MB (megabytes).
The damaged disk is of 1TB, but we have only arround 180GB-200GB saved it.

I have a other disk to save the information is 1TB Toshiba.

The damaged disk say error after 597MB (Megabytes) or 1.180.000 (no remenber where exact). and the next sector say bad bad.

I´m learning now about DDrescue the man page and some tutorials.

I will try make a copy 1TB disk hitachi to 1TB disk toshiba disk with DDrescue.

I hope the hard drive reach me.

@Nick_CT: Thanks for your reply

It's been an age since I last used it

Understood - you don't need to use utilities like ddrescue, when you have professional cloning equipment!

@hibrid0:

The damaged disk is of 1TB, but we have only arround 180GB-200GB saved it.

Thanks, that is clear. If the 1TB disk is using only one partition (one drive letter), then the simplest approach is still to try to clone the whole of the disk, and then use logical recovery software on the result.

If the disk was split into multiple partitions / drive letters, then the advice may be different.

I have a other disk to save the information is 1TB Toshiba.

This 1TB Toshiba will probably not have exactly the same number of blocks, as the 1TB Hitachi. Hopefully it has more, but if not, then you may need a slightly different approach.

the next sector say bad bad.

That is not exactly what the R-Studio log was showing. Some sectors still seemed to be readable, between sectors which were unreadable (look at the error positions / addresses in the log - some error positions are likely contiguous (4k apart, so perhaps 4k blocks being used for reading), but some are not.)

Personally I would approach this using ddrescue (with a log file), to quickly clone as much of the disk as possible as is easily readable now (no retries, no trim etc.). Then IMHO the next decisions depend on whether there is a pattern to the unreadable areas (ie where they are on the disk).

Hi Vulcano I go to try with this command:

ddrescue /dev/sdb /dev/sdf

How Can I see the disk are connected to my machine?
I try with fdisk -l and show this error:
"warning: Unable to open /dev/sr0" read-write (read only file system).
/dev/sr0 has been opened read only error /dev/sr0: Unrecognised disk label.


I have the next connect disk

1. Disk (boot with windows) (NTFS)
2. Disk 1TB damaged with USB adapter (connect on the freezer...) (FAT)
3. Disk Toshiba New by USB conection (NTFS).
4. Optical DVD internal (Boot Linux Ubuntu Remix).
5. Optical DVD external writer.
6. Pendrive USB 8GB.

Well I try with Ubuntu remix but don´t work "startx" and I´m downloading Knoppix DVD.

Where Can I buying professional equipment and training?



This is really great experience.
I have had cases of success with over tools before.

While here he made a big mistake and was using HDD Regenerator (AKA HDD Terminator)

information is less accessible now. After running HDD terminator.

Just ran up to 597MB

Before HDD terminator Stellar Work and show some files and folders, after not work more.
I could get was the 489MB with File Scavenger (200MB are usable, the other part of software).


I need acces to this disk, I have advantage.
This Disk was have a software to make backups (ArcSoft TotalMedia Backup) and maybe have many copys of same files.

Try using MHDD, but it does not recognize USB drives.
MHDD is recommended to use?

[Vulcan]

@hibrid0:
Sorry, but I deliberately did not promise to "hold your hand" through the whole recovery process - I do not have time to do that, as it would need many hours of assistance.

Also, from your comments, it is clear you did not understand my recommendations for how to use ddrescue, and I cannot understand many of your new comments. Therefore with this type of communication problem, and with you asking so many questions, "remote support" in a complex situation, and with complex tools like ddrescue, is not sensible.

I suggest you either:

(a) Use a more simple cloning program that can cope with unreadable sectors (so NOT Acronis, Ghost etc.), and you must accept that you have less control (and perhaps less success) than using ddrescue;

Or (b) get some local help so that there is no language problem, e.g. by paying a local DR company, or a local friend who has experience with this type of issue.

To answer your latest question - no, I would not use MHDD for cloning a large disk. Also FYI I would not use USB connection for the "problem" disk. Experience shows this often introduces more problems / less success. Instead use a direct SATA connection for the problem disk.

You will find some discussions about available cloning programs by searching this board - for example this thread:

the-best-disk-cloning-hardware-software-t10396.html

however it discusses both professional (expensive) tools, as well as software for end users. Also, some info may be out of date (e.g. new free versions of HDClone are listed as not including the feature to cope with unreadable sectors - only the "basic" paid version is listed as including that). However that thread will give you some ideas of your "DIY" options.

Vulcano I understood your recommendations about DDrescue, I´m to finalize the Knoppix DVD to Download.

And I go to connect on SATA interface on my machine.

And my question about MHDD was in case of really this tool are good or bad.

The answer depends on how you use it, and what you are trying to do.
