See also Wikipedia:List of data recovery software#File Recovery If your camera does not support UMS mode and therefore cannot be accessed as a block device, your only alternative is to use a flash media reader and physically remove the storage media from your camera. Some cameras have a menu item that allows switching between the two modes refer to your camera's user manual. The alternative to PTP mode, USB Mass Storage (UMS) mode, is not supported by all cameras. In this case, "transparently" means that PTP devices do not get block devices. PTP cameras are transparently handled by libgphoto and/or libptp.
Digital cameras operating in PTP (Picture Transfer Protocol) mode will not work in this regard.
In order for some of the utilities listed in the next section to work with flash media, the device in question needs to be mounted as a block device (i.e., listed under /dev). # dd if=/dev/target_partition of=/home/user/partition.image To make an image, one can use dd as follows: are likely to be small enough to image in many cases.īe sure to read the man pages for the utilities listed below to verify that they are capable of working with image files. For example, flash memory devices like thumb drives, digital cameras, portable music players, cellular phones, etc.
Mount it read-only.Īs an alternative to working with a 'live' partition (mounted or not), it is often preferable to work with an image, provided that the filesystem in question is not too large and that you have sufficient free HDD space to accommodate the image file.
Keeping the drive in the freezer with cables connected to the recovering PC works great.ĭo not attempt a filesystem check on a failing drive, as this will likely make the problem worse. A bit of time in the freezer is appropriate, but be careful to avoid bringing the drive from cold to warm too quickly, as condensation will form. (Discuss in Talk:File recovery)Ī tried and true method of improving failing drive reads is to keep the drive cold. This paragraph is mostly untouched since 2009 and might not be applicable to modern drives. Reason: Although written on the blog of a data recovery company, it seems there are voices against the "freezer trick" on drivers from the last 10 years.
