The error message I receive is VSS: Can't read volume data (Source: Hard Disk Manager). BR 2013 - it worked before. Toshiba 64 bit laptop / Win 7 - Home Premium. I had a backup and some diffs. I decided to start from scratch and deleted them. I backup to an external drive on my home network. It ran for 2 hours. It appeared the 1st step ran good but then crashed and the following 3 steps said "cannot run due to previous errors" and I received the message, "VSS: Can't read volume data (Source: Hard Disk Manager)." I tried again, same thing. I ran chkdsk.exe /f. Same result. I called Paragon and was advised to run chkdsk.exe /r. After that it crashes in step 1 after a 1/2 hour and I receive the same message. I did repair in control panel and same result. I uninstalled and reinstalled. Instead of opening in advanced mode as before, it opened in basic mode. I tried to back up in basic mode and got the same result after a 1/2 hour.
This reply is a little late but maybe this will help someone else. I got the same error msg trying to backup with Paragon Backup & Recovery 2012 free addition. VSS: Can't read volume data (Sourse: Hard Disk Manager) I tried everything from chkdsk /r and other HDD doctor programs I got the same result. After reading a bunch of post, one of them said to download the software from hard disk manufacture in order to repair / diagnose the HDD. In my case it was seagate. After downloading and running their windows based HDD repair program I got a msg that said it couldn't repair in windows mode and it recommended the DOS version called SeaToolsDOS. So I downloaded from seagate's website and followed their instructions to created an image cd to use as a boot disk. I ran the boot disk and it loaded the DOS program. I then ran a long scan mode and it found 99 errors on HDD blocks. I had to re-run the program 7 times in order to repair all the errors. ( i guess it can only fix 99 at a time) after all the errors were fix I was able to backup with paragon backup. YEAH!!! During the backup process Windows flashed a couple of msg's saying my hard drive was failing and suggested I backup my computer. Duh! anyway I'm ready for a hard drive crash. bring it on!
Thanks for posting your results. I experienced something similar and resorted to Western Digital diagnostics, which cleaned up the problems. Both Paragon and Easeus ToDo Backup were reporting read/write errors, so I knew that the issue was not just a Paragon issue. Hopefully your post will help others who encounter this error resolve their problems. There is also an excellent program, called SpinRite, which is a bit pricey, but is very good at dealing with, recovering data, and otherwise managing dying hard drives. I have used it several times for folks with some serious success. Have a great day. Regards, -Phil
