	I just picked up a 74GB VelociRaptor I'd like to use only for S@H. When doing a new install of Boinc if I just change the drive letter when I install will that place all the Boinc & S@H files on the Raptor? Or will I have to male some changes once Boinc is installed to set it up this way? ____________ My Computers: █ Blue Offline █ Green Offline █ Red Offline

When you run the BOINC installer, click the 'Advanced' button on the third screen - that'll allow you to change two separate installation locations. The 'Program' location is only used for BOINC's own files - the ones you are currently installing. Those are just read once each time you start BOINC - you'd gain nothing by moving them to the new drive. The 'Data' location is the one you want to change. In this context, even the SETI program files are treated as data by BOINC: so yes, all the active (changing) BOINC files, and all the SETI files, would end up on the new drive after installation with just that one change. No further work is needed.

	Great information, thanks! Will doing it this way create any issues when installing/running Lunatics? ____________ My Computers: █ Blue Offline █ Green Offline █ Red Offline

	Great information, thanks! Will doing it this way create any issues when installing/running Lunatics? No. The Lunatics Installer reads the BOINC location information left in the Windows registry by the BOINC installer, and will find the working files OK.

	Sweet, sounds like my little Raptor SETI drive project will be easy to setup. Since the Raptors are server grade Hard drives (from what I understand) it should be well suited to the frequent read/write of WUs. ____________ My Computers: █ Blue Offline █ Green Offline █ Red Offline

	Disk I/O in SETI is very low, Raptor won't give any noticeable difference than normal(SATA and access time around 15 ms) drive. Sorry to disappoint you on this matter. But for many other things VRs are awesome. I have two 300 GB myself, one per workstation. I didn't know there are 74 GB models of VR. Very nice. As long as needed mostly as system drive(and as a drive for code compilation in my case) this low capacity, but probably less expensive model, is very welcome. ____________

	Oh well. It can still be my SETI drive as my OS drive in an 120GB SSD. ____________ My Computers: █ Blue Offline █ Green Offline █ Red Offline

	Some of you guys are really grasping at straws trying to get more rac. Faster HDD will make absolutely NO difference at all for boinc projects. Unless you had a floppy before. Get a grip, will you, what you have is a form of OCD. Geez. :)) ____________

Can't hurt when I only paid $35 for the drive. ____________ My Computers: █ Blue Offline █ Green Offline █ Red Offline

As long as needed mostly as system drive(and as a drive for code compilation in my case) this low capacity, but probably less expensive model, is very welcome. When they changed from the Raptor to VelociRaptor name one of the first models was the 74GB one. Probably to replace the original 74GB Raptor. I had thought about getting one at the time to replace my older drive as it was also SATA 3Gb instead of the 1.5Gb. I instead went with a large array of TB drives for about the same money. Another options for installing this drive to use just for S@H would be to mount it as a folder. So if you had C:\ProgramData\BOINC\. then you could just mount it as that folder. It has been a while since I have done that process. So I'm not sure if it as easy as it once was. ____________ SETI@home classic workunits: 93,865 CPU time: 863,447 hours Join the BP6/VP6 User Group today!
