**Can fragmentation of the disk affect the results of the recovery?**

It depends. Fragmentation in NTFS should not affect the recovery results, as information about a file's allocation is stored in an MFT entry. In FAT file systems, this information is stored in the FAT, leaving the recovery program with only the entry point of the data if that FAT is missing. Fragmentation can ruin the day here. EXT, HFS+, and APFS are not affected in the sense that if a file can be found, its allocation comes along with it. That means, if the file shows up in the [Recovery Tree](https://runtime.org/help_gdb_chm/step3.htm), it should be recoverable. If it does not contain the expected data, you should review your selection in the [Select File System](https://runtime.org/help_gdb_chm/step2.htm) screen.

**Can I investigate the quality of my recovered files before I buy the software?**

Yes, GetDataBack contains a build-in [viewer](https://runtime.org/help_gdb_chm/viewfile.htm), which lets you investigate the [quality](https://runtime.org/help_gdb_chm/step3.htm#quality) of your files. You can also [open](https://runtime.org/help_gdb_chm/step3.htm#open) the files with their original application without having to [buy](https://runtime.org/help_gdb_chm/register.htm) the program.

**Can I use GetDataBack to recover data from CDs, CDRs, and DVDs?**

No, GetDataBack recovers from hard drives, SSD drives, floppies, USB drives, SD cards, Flash drives, and Images, but it is not suitable for restoring data from optical media.

**Can I use GetDataBack to recover data if the BIOS of my computer does not recognize my hard drive?**

No, if the BIOS does not recognize the hard drive, our software is not able to perform a recovery. Please make sure that the connections, jumper settings, and controllers are ok. If the hard drive is still not recognized, try to connect it to another computer and see if it gets recognized there. If your drive is a USB drive, remove it from its enclosure and attach it directly to the internal SATA cable.

**During the scan with GetDataBack, I receive a disk error. What does this mean?**

A [disk error](https://runtime.org/help_gdb_chm/io_error.htm) is a sign of a hardware problem. It might be better to make a [disk image](https://runtime.org/help_gdb_chm/create_image.htm) first, as every attempt to access data can increase corruption. After successfully creating an image, you can use the [image file](https://runtime.org/help_gdb_chm/image.htm) as an input for GetDataBack. It can also be appropriate to continue and ignore the error, especially if you scan the drive with a low [sophistication level](https://runtime.org/help_gdb_chm/sophlevel.htm), and intend to recover only a couple of files.

**After the scan, GetDataBack reports "No file system found". Why?**

1. The drive might be [encrypted](https://runtime.org/help_gdb_chm/gdbfaq.htm#encrypted_drives), thwarting any recovery attempts.
2. It might be too [damaged](https://runtime.org/help_gdb_chm/io_error.htm) to read any valuable data from it.
3. It contains a file system that is not [supported](https://runtime.org/help_gdb_chm/intro.htm#supported_file_systems).
4. It contains a supported file system, but this file system is unchecked in the [settings](https://runtime.org/help_gdb_chm/options.htm#file_systems).

**How can I optimize the quality of the recovery?**

In the [Select File System](https://runtime.org/help_gdb_chm/step2.htm) screen, be sure to choose the file system which contains the most applicable information about the partition you are trying to bring back. If none of the entries resemble that partition, increase the [sophistication level](https://runtime.org/help_gdb_chm/sophlevel.htm). Before you buy a [license key](https://runtime.org/help_gdb_chm/register.htm), please test enough files to ensure you are satisfied with the recovery results.

If you are just concerned about some individual files, try checking [Duplicates](https://runtime.org/help_gdb_chm/step3.htm#deleted) in the Recovery Tree. That might bring up different versions of the files.

See also our comprehensive [Checklist](https://runtime.org/help_gdb_chm/checklist.htm).

**I do not find certain files in the recovery; how do I get these?**

Do a [Search](https://runtime.org/help_gdb_chm/search.htm) for your files for a chance to find them even in some hidden subdirectory.

Check the recommendations in [How can I optimize the quality of the recovery?](https://runtime.org/help_gdb_chm/gdbfaq.htm#optimize) as well as our comprehensive [Checklist](https://runtime.org/help_gdb_chm/checklist.htm).

**I cannot open the recovered files. Why?**

There are two possible reasons for the inability to open the recovered file:

1. New data overwrote your files. In this case, there is no way to retrieve the files.
2. The second possible reason is that you have chosen the wrong file system entry in the [Select File System](https://runtime.org/help_gdb_chm/step2.htm) screen. Be sure to choose the file system that contains the most applicable information about the partition you want to recover. Try other entries from that list.

See also our comprehensive [Checklist](https://runtime.org/help_gdb_chm/checklist.htm).

**I don't know which file system I had on my drive before it crashed. What shall I do?**

GetDataBack Pro supports all Windows file systems and most Apple and Linux file systems, so you can probably proceed. GetDataBack Pro automatically recognizes the file system.

**Is it safe to run GetDataBack for my crashed hard drive?**

As long as your drive does not have a physical problem, it is safe to use GetDataBack. The program does not change anything on the crashed drive, as it is a read-only software. Install the software on a working Windows computer and attach the hard drive, which contains the lost files, as a second hard drive to this computer. Make sure that the BIOS recognizes this hard drive.

If, however, GetDataBack reports [read errors](https://runtime.org/help_gdb_chm/io_error.htm), you should pause and consider your options: One is to send the drive to a recovery lab. Another one is to [create an image](https://runtime.org/help_gdb_chm/create_image.htm) of the "bad drive" first and run GetDataBack for this [image](https://runtime.org/help_gdb_chm/image.htm) in the next step. Another option is to ignore the error and continue, which might be acceptable if you are scanning the drive with a low [sophistication level](https://runtime.org/help_gdb_chm/sophlevel.htm) and intend to recover only a handful of files.

**How do I recover data from a laptop or notebook drive?**

One option is to remove the drive from the laptop and connect it to the SATA cable of a desktop computer. Another option is to create a WinPE boot medium and run the recovery software from there. You can find instructions on how to create a boot CD or USB stick on our website at [http://www.runtime.org/peb.htm](http://www.runtime.org/peb.htm). Keep in mind that you still need enough space on a different drive to copy the recovered files.

**Will GetDataBack work on a hard drive larger than 2 TB?**

Yes, GetDataBack works on hard drives of any size. Keep in mind that your computer, its BIOS, the hard drive controller, and the operating system (Windows) must support the size of your drive too. This support might be a concern if you try to recover data from a modern large drive on a machine that is a couple of years old.

**How do I recover deleted files?**

In the [Recovery Tree](https://runtime.org/help_gdb_chm/step3.htm#deleted) screen, check the ***Deleted*** checkbox. Use the [Search](https://runtime.org/help_gdb_chm/search.htm) feature to find the files as they might be tucked away in some subdirectory. The outlook for a successful recovery of deleted files very much depends on the file system and the circumstances. It also matters how long you continued working with the drive after you deleted the files.

In **Windows (NTFS, FAT)**, "Permanently deleted" files can be found in their original directory (if still available). Files from "emptied recycle bins" can be found below the RECYCLE directory. Note that these files have lost their original filenames, but still have their original extensions.

In **Linux EXT and Apple HFS+ partitions**, GetDataBack is not suitable for the recovery of deleted files, as the operating system removes the allocation information. Files can be undeleted using the file system journal, though, if enabled. Look out for un-deleters that examine the file system journal to recover deleted files.

Apple APFS makes the recovery of deleted files simple, as it regularly creates "checkpoints". In GetDataBack, you can [access into the APFS file system through these checkpoints](https://runtime.org/help_gdb_chm/apfs_select.htm), and find deleted files.

**How do I recover encrypted drives?**

Third-party software-encrypted drives behave transparently, once they have been unlocked. That means you can run GetDataBack on them as you would on a regular drive. It might be helpful first to [image](https://runtime.org/help_gdb_chm/create_image.htm) the unlocked volume, and later run GetDataBack for this image.

Some USB drives (WD) are hardware-encrypted with the encryptor build into the USB controller. The good news is, most of these controllers use the same key.

**How do I recover encrypted files?**

The short answer is you can't. By design, you can not recover encrypted files without knowledge of the decryption key. If you do know that key, however, recovery might be possible, depending on the file system and the circumstances, but is beyond the scope of GetDataBack.

**How do I recover a RAID?**

If you can still access the RAID volume (this is the *combined* RAID, not the members), you can scan it like a regular drive. If the RAID is not accessible or broken, you need to "de-stripe" it first. Use [RAID Reconstructor](http://www.runtime.org/raid.htm) for this. It generates a VIM file ([Virtual Image](https://runtime.org/help_gdb_chm/arrangement.htm)) that, together with the member drives, you can run GetDataBack on.

**How do I recover files from a network drive?**

That is not possible directly. You must take the network drive offline and attach it physically to the machine running GetDataBack. It must be a single drive with a [supported file system](https://runtime.org/help_gdb_chm/intro.htm#supported_file_systems). If the network drive internally consists of several drives, see the next question.

**How do I recover a NAS (Network Attached Storage) device?**

You can not recover data from a NAS over the network. For GetDataBack to work, the drive or drives must be locally and physically present at the computer running GetDataBack. The file system on the NAS must be [supported](https://runtime.org/help_gdb_chm/intro.htm#supported_file_systems). If the NAS consists of more than one drive, you need to run RAID Reconstructor first, to obtain a VIM file ([Virtual Image](https://runtime.org/help_gdb_chm/arrangement.htm)).

**Why don't I see my drive after starting GetDataBack?**

Make sure the drive is connected correctly, and the BIOS detecting it. If it is a USB drive, attach it directly to the internal SATA cable.

**What is your update policy?**

Updates of GetDataBack are always free for licensed users. You can download the latest version on our website and activate it with your license key.

**Can I use DD images in GetDataBack?**

Yes, you can create Linux DD images that are compatible with GetDataBack. For example, the following command would create an image in the user's home directory:

`dd if=/dev/hda of=~/hdadisk.img bs=4K conv=noerror,sync`

Make sure you include the `conv=noerror,sync` options, so the image does not stop on [read errors](https://runtime.org/help_gdb_chm/io_error.htm), and the offsets are preserved.

**Does GetDataBack support Unicode character sets?**

Yes, it does. You can recover files whose names are encoded in non-standard character sets. These include all Unicode character sets, such as Japanese, Chinese, Korean, Russian, Greek, etc.

**Why can I not copy the recovered files to a network drive?**

Please map the network drive to a drive letter. If you still can not copy to the network drive, check [this](http://support.microsoft.com/en-us/help/937624/programs-may-be-unable-to-access-some-network-locations-after-you-turn).

**Can I reuse a drive after I recovered my data from it?**

You should not, as it can not be trusted any longer, unless you know precisely your data loss was not caused by physical problems with this drive.

Another reason is, you might need to come back to the old drive, in case you miss some files in the recovery or the recovered files turn out to be corrupt.

**How do I recover a drive from a Virtual Machine?**

Start a VM running Windows. Inside the VM install GetDataBack Pro. Shut down the VM and attach the drive you want to recover data from in the VM control panel, as well as a drive to hold the recovered files. Then run GetDataBack within the Virtual Machine.

**How do I interpret the status line?**

The status line gives you information about the ongoing data recovery, [more...](https://runtime.org/help_gdb_chm/statusline.htm)
