What is wrong with my raid array?

As you can see the performance is not as high as would be expected. :D Also the drives do not show up in windows, only in programs like hdtach, speedfan, hdtune etc.



And in the storage manager program the drives show up as 0MB/s. :confused:
 
I wouldn't worry about what Storage Manager is telling you. Storage Manager supports quite a few Adaptec cards using different technolgoies, and it may simply be that yours doesn't support that query.

I'd suggest checking you have the most up-to-date BIOS on the card, and also check if Windows needs any drivers.

I have an Adaptec RAID card. In RAID-1 it isn't as quick as my primary SATA drive, but it's certainly not that far behind. Unfortunately, my system runs Linux and I have no experience using it with Windows.
 
I am using the latest drivers, but I will try to update the controllers bios, strange thing is though that in the bios, the first drive shows up as SCSI II, when it's SCSI III, and the other two drives interface speeds don't show up at all, neither do their capacities. The bios is also extremely annoying as it does not support usb keyboards. Idiot programmers. :mad:

To get the BIOS working with USB keyboards, try disabling the BIOS POST boot logo and enabling USB keyboard, USB mouse, and any legacy USB support options in the BIOS.

The other thing that can cause SCSI slowdowns is poor cabling or improper termination. You may want to check the SCSI cable and pins are undamaged and connected properly, and that any termination options (both on drives and the controller) have been set correctly.
 
Thanks, got usb working now. All the scsi pins are undamaged and the controller termination has been tried on both auto and on, and there is an lvd active terminator on the end of the cable.

On the hard drives there are two sets of what look like half size jumpers which haven't been set, one on the underside and one on the back, are these supposed to be set to anything? On the 80-68pin adaptor there are jumpers which I have used to set the device ID and synchronous mode.
 
You'll probably need to check the drive manuals. Some devices have onboard termination, which you'll need to disable. Unfortunately I'm only familiar with the pre-LVD generations of SCSI.
 
After upgrading my pc, the drives have now magically appeared and I have managed to install windows on them. Still trying to resolve the throughput issue though, interestingly though it doesn't actually seem any slower than my sata hard drive.
