It depends on how long the FORMAT took -- if it just was a few seconds, then what happened was a 'empty' table-of-contents was written, to make the drive appear to be 'empty', and nothing was written on the other 99% of your disk-drive. Thus, some "file recovery" software can be used to read that 99% and "stitch" together each block of data, to reconstruct the old table-of-contents.

Or, if the FORMAT took several minutes, then every block of data on the disk-drive was overwritten by a block of 'zero' bytes, making your data _almost_ unavailable. In that case, you need to find a 'friendly' federal agent (maybe Department of Homeland Security) to use 'advanced' techniques to read the 'residual' magnetism that is 'under' the block of 'zero' bytes, to recover the data.

Hard drive does not recognize a file system


Buy a software called EASUS DATA RECOVERY WIZARD, install it on a working computer. Connect your hard drive as a slave and open the program. Use the Complete Recovery Method to recover all your files. It is usually pointless to try and recover system files. Unless you want to recover your documents and files that were there in the hard drive.

Hard Disk Data Recovery


Definition of Hard Disk: Hard Drive is a storage device where you can store any types of data and file. Hard Drive is available as external and internal device. We know PC storage device as internal system Hard Disk. When you save data or install programs on your computer, the information is typically written to your Hard Disk. The Hard Disk is a spindle of magnetic disks, called platters, that record and store information. There are several interface standards for passing data between a Hard Disk and a computer. The most common are IDE and SCSI. Hard Disk is made of one or more aluminium or glass platters, coated with a ferromagnetic material. Most Hard Disks are found as Parallel ATA (PATA), Serial ATA (SATA) or SCSI device.

Difference with Floppy Drive:
The term hard is used to distinguish it from a soft, or floppy, disk. Hard Disks hold more data and also faster than floppy disks. As an example a Hard Disk can store anywhere from 10 to more than 100 gigabytes, where most floppies have a maximum storage capacity of 1.4 megabytes. Floppy is more risky device than Hard Disk for losing data.
Problem with Hard Disk:

Most common problems of Hard Disk which may arise anytime are Booting problem, OS Installation problem, Hard drive crashing and another Hard Disk not showing original space or not showing partition etc. But in every case the risk is loss of data. In some of cases formatting and reloading of Operating System can recover your Hard drive and make it useful but formatting can recover a blank Hard Disk only without data. But you have to recover Hard Disk with data, so formatting is not possible.


Data Recovery:

Data recovery is the process of retrieving back data from the damaged media. The damage of storage media can be physical damage and logical damage. The data is retrieved back by recovery experts after determining the type of the damage caused to the storage media. Most of cases data recovery is important and formatting is not possible there. So that I need to choose another way for solution of this type of problems of Hard Disk. The first and secure way to recover a Hard Disk is using data recovery software.


Recover Data from crashed Hard Disk: Power surges, Software Corruption or Malfunction, Hardware or system failure, Natural calamities, User errors may crash your Hard Drive. Data recovery software helps to retrieve or recover the data from the crashed hard Drive. Data recovery software gives an easy and Graphical User Interface with less difficulty so that the data can be recovered easily. The recovery software helps to recover the data and restore them on a second Hard Disk, the Hard Disk being connected to the computer and recognized by the BIOS, the recovered data can be stored on a safe location on the second disk.


Logical data recovery: In a data loss situation when the Hard Drive is perfectly fine and the BIOS recognizes the Hard Drive but reports a read error, logical data recovery technique is very helpful. Here the files that are damaged or corrupted by any user error or virus attack are rebuilt rather than repairing the Hard Drive.


Fragmentation: When the FAT entry is lost during accidental file deletion, formatting or partition deletion that particular block of Hard Drive becomes inaccessible. Some data recovery software makes an attempt to rebuild the files without a FAT entry. This technique is very efficient if the file size is smaller than the clusters size. But it is inefficient in recovery the larger files.


Data Recovery from deleted partition: Partition is allocation of memory in different sections. Each partition will be like separate disk drives. Partition is very use full when the user is using operating systems more than one. Usually after formatting the disk it may not be able to recognize a partition because of accidental deletion of the partition table or by virus infection. The partition is not actually deleted; it can be recovered by using recovery tools and copy the data present in the partition to the required destination. Formatting the drive erases a large amount of data present on it, but not all the data. The recovery of the data depends on the fragmentation of the file system as the parts of files are being placed on different places in the drive. The data recovery software will assume that files were not fragmented and stored in continuous clusters. If the partition was formatted using different file system, then recovery process will be very complicated.


Another Data recovery process: If you don't have any data recovery software you can try another process to recover data. Attach the Hard Drive with another system in slave or second SATA.If detect the drive then boot to the first Hard Drive and use the bad Hard Drive as secondary. Then you can copy the data from the second drive to first drive easily. Here have another process to recover data from a crashed Hard Disk. But it is so risky, and should not try to do this for an inexpert person. First pack the Hard Disk in a bag properly where moisture can't attack. Now freeze it upto get chill. After freezing quickly attach with a system in secondary, and copy the data within the Drive will come in room temperature.

So the most secure process to recover data from a Hard Disk is to use data recovery software. It is available in market.

How to recover tally data from the twice formatted NTFS hard disk partition ? my operating system is window xp service pack 3


Hi, Mac data loss is actually a hard task for many Mac users 'cause most of them think the Mac OS is a complicated computer operating system (At least I think it is complicated). Here are some tips you need to know after data loss happened.
1. If you meet the file loss situation, keep calm and stop using your computer to do any read or write operation until you find the way to recover the lost files because any wrong operation.
2. If you've lost a file, time is of the essence. As new files saved to Mac hard drive or storage devices, the original files gets overwritten. So do not use the drive or disk which your deleted files are stored before at all, until you have completed the scanning and recovery process.
3. The system crashed or the files loss situation happens occasionally, so remember build a backup for the files periodically is strongly needed.
4. If you meet the file loss situation again, stop using the Mac or storage device right now, use another computer to process the files recovery.
5. Remember this, no matter at the normal time or after files recovery, build a backup for the files periodically is the best method to protect your files from data loss situation.

Maybe you can try uFlysoft Data Recovery for Mac, it can recover empty trash on Mac only in three steps: Step 1. Launch the software to scan the device where your files deleted
Step 2: Preview the scan result files and make mark if it is the one you find
Step 3: Recover files

My sandisk cruzer says it is not formatted. it contains all my documents but I cant open anything if i format it i will lose all my data help!!!


Possible Reasons:
1. Your USB flash is too old and can be corrupted with time went on. As you know no hardware can be life-long ever.
2. There are bad sectors in the specific area of the disk that is required for a file system, e.g. for a boot sector or the FAT table sector. Since such a drive is obviously not possible to use, Windows refuses to format it.
3. Sometimes, you cannot format the drive to the FAT file system if it has been formatted to a file system which is not recognized by Windows. Such a drive should be reformatted to NTFS first, and then to the FAT file system.

Solution:
Step 1: Try the problem USB on another computer (better be most common Windows OS). See if the device can be accessed normally. This way can clear the buffers and eliminate incompatibility. Sometimes it will let the error disappear and make the drive work normally again.
Step 2: If the first method still won't help. Try recovering the data with some data recovery programs first of all. If you are running Windows, you can use Data Recovery for Windows. For Mac OS X users, turn to Data Recovery for Mac
Step 3: After the files are recovered, then follow those steps to try format the error USB drive (connect the disk to your PC first). My computer -> Properties -> Manage -> Computer Management -> Storage -> Disk Management -> select the problem drive and then format it from here.
Step 4: It's not over. After formatting, try use the data recovery software recommended in #2 to re-scan the drive to see if you can harvest more data. Good luck!

How to recover data from a faulty hard drive


As long as the drive is spinning you should be able to recover files with any decent file recovery program. I've just spent half a day recovering about a 1000 photographs that had been deleted and apart from all the unwanted stuff that also gets recovered, it all went well.
If the drive is not spinning or is making clicking noises then your options are much reduced. You will most likely have to use the services of a professional data recovery company - and they don't come cheap.

Undelete/unformat a Mac formatted external hard drive.


The theory to unformat a Mac hard disk is, when you format a Mac HFS+/HFSX Volume or format a external hard disk, the data are not really wiped. Format process just marked your Mac hard disk as available to reuse, no matter it is quick format or complete format. So if you put if you fill in a mount of new data to your hard drive, then the formatted data are overwritten, your will permanently lose your formatted data.

Follow this guide to unformat your mac hard drive or formatted external hard drive on mac.

bricked hard drive? Would folling this lead to a full hard drive format or just unbricking a drive like people sat it does?? Also any other ways that might help would be great to know, heres what i'm talking about! "Fixing The Drive NOTE: Commands for you to type are in red boldface. Pay attention to upper & lower case - it is important. Turn on power to the RS232-to-TTL adapter and the hard drive. After a few seconds, Press CTRL+z. You should then see a prompt like this: F3 T> If not, swap TX & RX wires. Access Level 2 (type /2): F3 T>/2 (enter) F3 2> Then spin down the (disconnected) motor: F3 2>Z (enter) Spin Down Complete Elapsed Time 0.147 msecs F3 2> Very carefully, remove the cardstock that you placed between the PCB and the drive head contacts. Carefully replace and tighten the 3 loose screws. I suggest using a small piece of masking tape to help you hold the screws while you put them back in place.

Once seen, drive can be turned off. Power down everything, place drive back into your computer, and confirm that it's working." Thanks.
