Snapman.sys
I made a big mistake.
I have a system running XP Pro with True Image Echo which I have just replaced with a new system with Windows 7. ( The XP Pro system is to be reformatted as it has a few problems). My version of Echo would not run under Windows 7. To enable me to copy my data files to the new computer I installed True Image Home 11 to restore the files from the XP Pro computer that were backed up using True Image Echo. For whatever reason this did not work.
I then installed True Image Home 11 on the XP Pro computer but each attempt to back up files which I then planned to restore onto the Windows 7 computer failed. This may have had something to do with the fact that I still had True Image Echo installed on that computer. I then deleted all versions of Acronis from the XP Pro computer with the intention of then installing True Image Home 11 to match with the Windows 7 computer. However, after I deleted all record of Acronis from that computer I had to reboot and I was then confronted with the dreaded blue screen at boot up, and the message:
*** snapman.sys - address B854c946 base at B8542000, Datestamp 46974e0c
I cannot now boot the XP Pro computer
I understand that this file is integral with Acronis products and is integral with the boot process when Acronis is installed......which now is not.
I tried the Acronis book disk....but that did not help.
Any suggestions on the best way to 'fix' snapman.sys and boot my system correctly?

Did you consider creating a backup from the Acronis recovery CD and then recovering the files you want on your Windows 7 computer?
That won't fix your problem on your XP computer, but it will allow you to accomplish your primary goal.
Hi Pat,
I do have a back up of the XP Pro computer on a remote HDD. It is the one of two I have been using for several weeks. The other one I played around with over the past 2/3 days transferring specific files (Outlook) to the Win 7 computer and as such I corrupted the original and incremental backups that were on that HDD. That did not seem to be a problem to me as I had the second one that was current. However, when I attempted to back up using True Image Home 11 the default was file was MyBackup1.....which also happened to be the same name for the original backup on that HDD to which the incremental backups had been linked to. I did not realize this until after a few seconds, but by then the damage had been done. It was this backup process that failed and I tried twice more and each time they failed. It was then I decided to remove all Acronis and start fresh with True Image Home 11.
When I proceeded to restore to Win 7 it kept asking me to link to MyBackup1, which of course had been corrupted.
This makes it all that more important that I get the XP Pro computer going as in effect I have no complete backup. I can access many of the individual files via the Win 7 computer but as soon as I attempt to copy/paste multiple files or directories or restore anything the system either asks for My BackUp1 or says I have a memory problem.
The only disk I have is the Acronis Boot Disk I made up ex Disk Doctor when I installed the Echo software on July '09. I do have the Echo software on my other computer which is running XP Pro. What recovery CD do I need to make that I can use on the XP Pro to gain access to snapman.sys?

If 'last known good configuration' boot option doesn't work...

But as you have to perform it on offline registry, you need to get your xp's registry on a working machine (preferably with xp too). Either bring your hard disk to it, or
back up windows\system32\config\system file using boot cd, then restore it on working machine using boot cd too (unless it has trueimage installed). Then after editing it, recover it back.
Offline registry editing - google it, e.g. http://smallvoid.com/article/winnt-offline-registry-edit.html
Remember to redirect all HKEY_LOCAL_MACHINE\SYSTEM\ mentioned in KB to your loaded hive name, not the live host registry.
Just in case - "restore it on working machine using boot cd" means restore anywhere but not into the same windows\system32\config\system on the live system.
Ray,
If dev-anon fix doesn't work, you could simple backup your XP computer (create a new full backup) using the Acronis True Image Home recovery CD.
Then, you can use the same CD to recover specific files onto your Win 7 computer.
You can create this CD by installing ATI 2011 on your Win 7 computer or by downloading your bootable media iso from your Acronis.com account where you have registered your ATI copy.
Again, this will not fix the XP computer, but you will be able to transfer the files to you Win 7 computer.
Hi Pat and dev-anon,
The latest on my problem.
I used my Acronis Rescue Media disk to boot up my XP Pro computer. I then selected Acronis True Image Workstation (Full version) from the selection and was then able to backup my total C;/ drive. Normally this would have taken an hour or so, but perhaps because of the state of my computer is the reason it took almost 10 hours. I was only backing up 223gb. I backed up onto a USB 500gb drive.
I then connected the USB drive to the Win 7 (64 bit) computer but got the following message when I attempted to access the backup file.
"An error occurred when opening the backup archive
cannot continue the operation due to either the backup is corrupted or it is used by another process, for example the backup has been mounted on a disk".
On the same disk I have the the earlier incremental backup....but because of me overwriting the initial full backup file I can only copy/download files that were created after the creation of the initial full backup.
However, I took the USB drive to another computer which has XP Pro installed and I can access the files of last' night's backup on that computer without any problem using Windows Explore.
So, why can I access the files on the XT Pro computer and not on the Win 7 computer yet can still access the earlier backup files on the Win 7 computer?
Is there a solution to this?
Ray
Ray,
Are you using the same bootable CD to backup and recover? You should be able to boot the Win7 computer on the CD and then restore selected file and folders.
If you are trying to open the TIB or access it, on the Win7 computer from within Windows, it is possible you are facing Windows security issues.
Are the Windows security settings on the root of the drive and the backup storage folder so that everyone has full control?
Hello Pat & dev-anon,
Some good news....at last!
I used the same Acronis Boot CD on the Win 7 computer and was able to use True Image Home to restore data files to the new computer. Unfortunately they now have all the same file date (25th April). I prefer to have the original created dates but at least I now have them. My last remaining problem is to get the XP Pro computer.
I note the instructions from dev-anon to update the Registry....but I must be thick as I am confused on the process required.
I have an Acronis Rescue Media disk and that gets me to when I was able to backup using one of the various Acronis Image Echo options (I selected True Image Echo Workstation (Full version). That is now done and I have restored my data files on the Win 7 computer (refer above)...but how di I now correct the snapman.sys file so that I can boot the XP Pro computer into Windows? Do I use the same Acronis Rescue Media disk? What are the steps to take?
Ray
Maybe you could use a windows XP recovery console on a bootable CD, find the snapman.sys file in system32\drivers and rename it to snapman.old to see if that would prevent the blue screen.
If you don't find it, you could try to find a copy of snapman.sys on your installation CDs and put it there.
I don't hold my breath because this .sys is a low -level driver.
But who knows, you might be able to get past the BSOD and then use a registry cleanup tool like Revo Uninstaller to rid the system of ATI.
You might have to go through the registry hack that dev-anon suggested...
Hello dev-anon,
I created a BartPE boot disk and have run regedit to reveal the Registry. I have progressed to HKEY_LOCAL_MACHINE/SYSTEM/Control/Class/{4D36E967-E325-11CE-BFC1-08002BE10318} and others and have checked all UpperFilters and there is no record of snapman in any of them....Part Mgr and others were there.
Next?
Regards, Ray
Hello Pat,
Using the BartPE Boot Disk I located the snapman.sys file in Windows System/Drives and renamed it snapman.old and rebooted. As you expected it did not work. The following message appeared:
***STOP: 0x0000007B (0XB84c3524, 0XC0000034, 0X00000000, 0X00000000)
Not too good?
Ray
Not too good, indeed. This is a typical stop code for a missing driver.
I am afraid that you are left with 2 options:
- reinstall XP if you can, or
- use the smallvoid link that dev-anon mentionned to edit the registry on your XP system from the boot CD. You cannot simply launch regedit, you have to load the offline hive of your XP system, as explained in the smallvoid article. Then you can delete the keys, according to the kb link and unload the registry hive back onto the machine.

Hi Pat,
OUCH!
I had a feeling that the news was not going to be good. I'll study the instructions from dev-anon and get up the nerve to carry out the changes required. At the moment it is going no-where, so the next step will either work or..............?
I'll get back to you with the outcome. If you have any revelations over the next few hours of any alternative....please let me know.
Regards,
Ray
Did you remove snapman from 'services' per that KB artice? (or made sure that it's not there) . If it is there, it will still bsod because driver the required for the service can't be found.
ps - As you have a BartPE disk, one more link - a specific manual for offline registry editing with bartpe http://windowsxp.mvps.org/peboot.htm
Ray G,
Did you solve your problem? How?
