Forgive the length of the post. I'm trying to be thorough in describing my problem.

I have been backing up files to an internal Samsung Spinpoint F3 HD502HJ NTSC formatted 500GB hard drive (let’s call it "A") for several months. Recently it reached capacity and I attempted to copy all of the files on it to a second NTSC drive (let’s call it “B”) prior to putting both drives into long term storage. I found I was unable to copy files from drive "A" that were put on that drive after a certain date. Any files put on drive "A" before this date copied just fine.

When I attempt to copy the problematic files, the process immediately hangs. The copy dialog box says that it is “Discovering items…” but usually won’t progress beyond that point. Sometimes it will start copying but at insanely slow speeds like 4KB/second. If I allow it to continue long enough it eventually gives up and gives me the following error:

Quote:
Error 0x8007045D: the request could not be performed because of an I/O device error.


I’ve had sporadic luck copying some of the files in this group just by trial and error but there’s no way I can try to spot copy each of the thousands of files that fall into the problematic date range.

I can open at least some of the files on the "A" Drive that won’t copy and they appear to open fine. I say "some" because again, I can’t individually test all of the thousands of files on the disk.

I tried moving the drives in question to different SATA ports on the motherboard and using different SATA cables. I’ve also tried copying in safe mode. No luck.

I looked at Samsung's drive diagnostic utility page (http://www.samsung.com/global/business/hdd/support/utilities/Support_HUTIL.html) but it appears to require the creation of a Floppy Disk which my system doesn't support so I didn't go down that road.

I ran chkdsk /f on that drive with the following results:

When I got the "insufficient disk space" errors, I deleted the files that I had been able to copy to drive "B" (those that had been put on the disk prior to the date mentioned above). This cleared up over 400 GB of space on the 500GB drive. I re-ran chkdsk /r but still got the "insufficient disk space" errors.

At this point, I'm out of ideas. Any suggestions on what I might do to recover the files in question?

Sounds like a job for DOS commands?

Are you familiar with them? If all I were trying to do was move files from one place to another... and windows wasn't going to let me... I'd probably go to my command prompt and try that.

Look up copy files in dos and it will give you some guidance. Or, hopefully someone in here will give some advice.

If that doesn't work... I doubt a floppy drive has to be a floppy- It could probably be a USB drive couldn't it?

You could also try "Recuva" if the documents are actually "lost" in the drive. I had some luck with it before but I'm not sure this is the solution you're looking for. I'm just thinking recuva might be able to piece together the parts that are scattered or damaged? Or at least be able to identify certain files as "hopelessly lost" versus "intact." Then you can select the remaining ones more easily instead of trial and error.

Let me know how it works out. I'm curious?

The Samsung's drive diagnostic utility page seems to have a zipped iso file to create a bootable CD
You might also try a bootable drive image software but an I/O error doesn't sound good so you'd want to check that drive.
If your drive is going out you might be working against the clock.
Also you can copy using Xcopy or similar, something that will continue to copy if it runs into an error although if the drive disappears in an I/O error then it won't help much.

Thanks for the feedback. DOS copy did not work. It simply hung when it encountered the first problematic file. I'll look into Samsung's drive Utility next.

Next step after that would be recuva. Again might help you sort out the good from the bad

The CD version of Samsung's disk diagnostic utility did not work. I googled it and others had experienced the same problem so I created a DOS bootable flash drive and used that instead. The hard drive came back with a clean bill of health.

I'll try a more robust copy utility next like recuva or richcopy (http://technet.microsoft.com/en-us/magazine/2009.04.utilityspotlight.aspx)and see where that gets me.

You could always just grab a copy of a bootable linux LiveCD and once you are in GUI mode with the source and destination drives attached, copy and paste. Another option would be to use Unstoppable Copy in UBCD4WIN and it will copy all the files it can read from the disk unless they are too far gone and cannot be read. If you have a copy of Symantec's Ghost (Bootable HDD copier), that would be a decent option. All of these options are only limited by the corruption of the drive and the read speeds of the drive, so it's really only a matter of time.

I have copies of all these things and here is a list of the URL's (Some which used to be freeware have only trial versions available and are listed as such below):

Knoppix v.6.2.1 CD ISO Version
Symantec Ghost v.15.0.0.35 Trial
Unstoppable Copier Program Download (Not the UBCD Version)
Ultimate Boot CD for Windows v.3.60 CD ISO Builder (You will need to Build the ISO and Configure it Yourself)
UBCD Build Instructions Page

Best of Luck!

:mrgreen:

EDIT: The Unstoppable Copier link is broken, I will try to remedy that tomorrow.

You can use CBD(Copy Bad Disk) to copy corrupted files.
