Lost data on hard drive and unable to connect

One day couldn't access hard drive it said ''your disk is not formatted do you want to format now'' I obviously clicked no, I've now removed the hard drive from my pc and am trying to access the hard drive on my vista laptop via a IDE to USB converter connection. it kinda recognises it and shows as a usb device, but you can't find the driver letter on my computer, and it constantly freezes. its set as a slave etc on hard drive but it's totally corrupt and not accessible. I've downloaded ontrack data recovery software, but what can i do if it won't recognise it as a drive?

any guidance would be much appreciated as i've got years of pictures and vids that im afraid i've lost....

i used the hard drive for just dragging and dropping files and im not sure if there was any operating system on there, if there was it would be windows xp....

I haave read that sometimes freezing the HD will allow limited time access.Worth a try. Next option is a data recovery service whom dissassembles the drives and reads the disk.Very expensive, I hear.

Reboot your system. Insert your Operating System Disc. You can repair it by using your OS disc. It will search for your previous OS installion and will give you options to Install a fresh copy of OS or Repair your previous installation. Choose Repair so that your files will not be deleted from your harddrive.

Unless you are willing to spend some big bucks on getting everything recovered and you have already tried all of the above steps everything on there is lost. I have gone through the same problem if you can't access it as a slave then you truly have lost all that was on there. If you buy a new hard drive consider a seagate. It is a little more cost wise but they have good life ratings and always try and back up files on dvd just in case.

Tip

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.
