Recently I needed to copy files from a failing drive.  With Windows Copy this is a pain because if reads bad data it chokes and I am left trying to figure what was copied and what was not and what more can be salvaged.  Fast copy to the rescue - but first, let's talk about the FAST part...


I recently had to move 100,000 files totally 45 GB (Adobe Lightroom Cache).  In the past I had compared several fast copy utilities to Window native copying and found very little difference due to the fact that Microsoft has actually been working a lot on improving Explorer's file copying intelligence and speed.

Explorer settled in at 1.56 MB/second - projecting many hours to complete.  It must have to do with having so many files because there haven't been any concerns when doing large copy volumes with a low number of files (like VM images).  Yet another web search for "fast copying" utilities unearthed FastCopy.

Fast copy has an instance rate of between 20-30 MB/s and finished the job in 21 mintues with an average copy speed of 33.82 MB/s.  (For both tests I used Win 7 64-bit running with 8 GBs of RAM.  FastCopy's cache was set to 128 MB).  System performance was not impacted.

Very impressive.

Now let's talk about file salvaging.  The challenge earlier in the week was salvaging the good files from a drive that had bad sectors.  (we are NOT talking about recoving the files IN bad sectors - just everything else)  For this type of coping a couple other things are needed besides raw speed.  The drive that this occured on is one that is used to build DVDs - so a lot of file system linking it utilized.  Many copy programs are not smart enough to notice linking (symbolic links, hardlinks, junctions, etc).  If a 3 GB .zip file is linked into three folders, copying the folder structure results in three full copies of the linked file.

So for salvaging files on this volume we need recognition and if possible preservation of any file system links.  FastCopy does this!

Second it needs to keep going when disk errors occur and third it needs to log errors so that it can be determined whether the lost files contained critical data.

FastCopy does all of these things!  So it rocks for copy large file sets (many files) and at recovering usable files from a damaged hard disk.
