from fast trak raid drivers from promise technologies
Installed with the miniport drivers for Promise hard drive controllers in both RAID and non-RAID installations. May be necessary in order to maintain preferences applied to the RAID array connected to the Promise controller

This file is made by Promise Technology Inc..
I started getting a message at boot up, stating that it was checking ide drives, and then it would say something about fastrak. I dont use my ide drives, I have serial ata and my drives are in a raid 0 so I dont use the promise thingy. Anywhoooo, I started getting this message after I disconnected everything from the back of my pc and then plugged everything back in except my zip drive, now if that caused the problem I dont know, but a screen came up prompting me to choose which drives I was going to use, and stupid me, I chose the ide drives,and I now get that message (at boot) all the time.

As far as I am aware this is a driver for promise techs raid card
put the file back into c:\windows\system32 folder and the error goes away.

Necessary for my Promise RAID Controller
RAID controller.
I think it's related to SATA drivers
Is installed along with a variety of drivers provided by Promise Technology, for use with their PCI-based storage interface products. The command line "rundll32.exe ulutil2.dll,SetWriteBack" instructs the Promise driver to use write-back caching, which increases performance but very slightly increases the risk of data loss due to cached disk writes not being committed in the event of a system crash or freeze. Can be removed from startup, but should generally be left intact.
As said above-- Promise Controller Driver
My Asus mother board has a SATA RAID controller built in. This dll is needed for it

Me think it may be Promise driver for RAID/SATA thingy. If you remove it your children will go sterile.

It is part of the Promise Raid controller for ASUS KV8 MBs
ptipbm is for NON-RAID apps, ptipbmF is for RAID and is only installed if the RAID drivers are installed (at least it's this way on an Asus P4C800-E Deluxe mobo)
In my setup I have an ASUS A8V Deluxe that has a Promise Fast Trak 378 chip that is for RAID or non RAID. The DLL in questions is needed to keep your RAID aray in sync, phase locked if you will, so that in the event of a drive failure your data to the spare drive is hopfully all intact. FYI I use RAID 1 mirroring for security.
i used SuperRabit MagicSet to look up autorun programs and found the item "Ptipbmf".then i searched in Google .and i know it's about driver from PT,INC.

Best practices for resolving ptipbmf issues

A clean and tidy computer is the key requirement for avoiding problems with ptipbmf. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the ptipbmf.dll process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries.
