you did not mention what OS you were using as the source for your build XP or 2003?

it looks as though you closed the base program without htting the slipstream button.
that is what your log indicates anyway...

it should look like this

see the bartpe tutorial in my sig below

ps since you do have the driverpacks in the correct folder (in plugins) you could use the plugins screen in pebuilder
hit config on # driverpacks.net - base -  hit config to enable
then hit refresh and you should then see ---> Yes # driverpacks.net - MassStorage 
in your plugins list.

I realize that you indicated you were a long time user of UBCD4win - but i am going by the log you posted.
I apologize in advance if i have not given you enough credit.

thanks for posting your INI and LOG and HWID's and a very good description
it is so nice to get such excellent detail from a new member!

Did you remove all the other mass storage drivers before useing the driverpacks
(removeing them from plugins and drivers folders?)

it may be to your advantage to get the latest build from UBCD4win
Creating a fresh source OS folder and fresh UBCD4win folder and starting "clean"

your version 3.06 has been replaced by 3.10

sorry this was so long in getting attn...

I've used UBCD4Win for quite a while and I find it an invaluable tool, especially for backup/recovery with the Acronis True Image 10 BartPE plugin. However, since I upgraded my rig to a Athlon 64 X2 5000+ on a Biostar TF560 A2+ a couple of months ago, I haven't been able to get any of my UBCD4Win builds to work to my satisfaction. It seems that, no matter what I've tried, UBCD4Win v3.6 can't detect my nForce RAID0 array (2x74GB WD Raptors) or the non-RAID disks on that controller. I have my SATA DVD-RW drive on a Silicon Image Sil3132 PCIe controller (by itself) and while I don't think UBCD4Win is loading the drivers for that properly (it's not showing in Device Manager under UBCD4Win), UBCD4Win is seeing the DVD-RW drive and can access it fine.

I've tried all of these techniques to slipstream or add those drivers, all to no avail:
-leaving the DriverPacks Mass Storage Textmode Drivers plugin enabled (by itself)
-disabling the Mass Storage Textmode plugin and adding the latest WHQL drivers to drivers\SCSIAdapter
-slipstreaming the WHQL drivers into the Windows folder with *restricted project name, please email Ben for support* v1.4beta and disabling the DriverPacks Mass Storage Textmode plugin before building the UBCD4Win ISO
-slipstreaming the WHQL drivers into the Windows folder with DriverPacks BASE and disabling the DriverPacks Mass Storage Textmode plugin before building the UBCD4Win ISO

I've scoured these forums, the UBCD4Win forums, and other BartPE forums, along with Googling my brains out, but I've come up with nothing that has helped much. I can't imagine that I'm the only one who is having this problem, but from what I've seen, no one is posting them or a solution. If anyone knows a way to rectify these problems so I can see all my drives in UBCD4Win, I'd greatly appreciate it.
