- 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, it
should be recoverable. If it does not contain the expected data, you should
review your selection in the Select File System screen.
-
Can I investigate the quality of my recovered
files before I buy the software?
- Yes, GetDataBack contains a build-in viewer, which lets you investigate the
quality of your files. You can also
open the files with their original application
without having to buy 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 is a sign of a hardware problem. It
might be better to make a
disk image first, as every attempt to access data can increase corruption.
After successfully creating an image, you can use the image file 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, and
intend to recover only a couple of files.
-
After
the scan, GetDataBack reports "No file system found". Why?
- The drive might be encrypted, thwarting any recovery attempts.
- It might be too damaged to read any valuable data from it.
- It contains a file system that is not
supported.
- It contains a supported file system, but this file system is unchecked
in the settings.
- How can I optimize the quality of the recovery?
- In the Select File System 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.
Before you buy a license key, 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 in the Recovery Tree.
That might bring up different versions of the files.
- See also our comprehensive Checklist.
- I
do not find certain files in the recovery; how do I get these?
- Do a Search 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? as well as our comprehensive
Checklist.
- I cannot open the recovered files. Why?
- There are two possible reasons for the inability to open the recovered file:
-
- New data overwrote your files. In this case, there is no way to retrieve
the files.
- The second possible reason is that you have chosen the wrong file system entry in
the Select File System 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.
-
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, you should
pause and consider
your options: One is to send the drive to a recovery lab. Another one is to create an image
of the "bad drive" first and run GetDataBack for this
image
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
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.
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 screen, check the
Deleted checkbox. Use the Search 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, 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
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
for this. It generates a VIM file (Virtual Image)
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.
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. If the NAS consists of
more than one drive, you need to run RAID Reconstructor first, to
obtain a VIM file (Virtual Image).
- 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, 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.
- 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,
