It's when you use a portable hard drive that attaches to your USB port. ie Sage 30 gigabyte. Iam using one now.

Volume Shadow Copy driver, an important part of Windows NT based systems (NT, 2000, XP, Server 2000, Server 2003). Sometimes comes up on BSOD's, copying the file from another computer usually solves this.

Volsnap.sys is an essential part of Windows O/S Volsnapp.sys otoh, is NOT! Volsnapp.sys is a Rootkit.DLL file and should be removed/disabled.

System File needed for booting

VolSnap.sys is indeed important to Windows. However, it is also a target for viruses. If it is corrupted by a virus, you will have to replace it. If you have Windows installation disks, you can copy it from that. But many computers come with Windows preinstalled and the installation stuff is stored in a partition on the hard disk. In this case you are screwed, since any virus that corrupted Volsnap.sys on the hard drive will likely do it to the restore partition. You can try copying it from another computer. Sometimes this works, sometimes it doesn't.

It is a system vital process, but the TDSS 3-4 rootkits corrupt this file, which causes many things. It it not anything bad. It's bad, in a way, when it's corrupted by TLD3 and 4. See bleepingcomputer.com/forums/forums22.html for instances of this; TDSS Killer is helpful for removing this rootkit causing corruption to VolSnap.sys
