Adaptec 3805 Compatibility Issues with Western Digital Blacks

Hello, a quick post / announcement that the Adaptec 3805 SAS Raid controller has compatibility issues with Western Digital Caviar Black drives. I don’t know if its an issue with all capacities of the Black series, but the ones i had were the 1TB ones, model number WDC-WD1001FALS-0.

After doing some research, it appears that the WD Blacks are NOT on the HCL for the Adaptec 3805 controller, but it took me some time to find this. I hope this post helps anyone who was going to go down this route.

Since i’d already gotten the WD Blacks, I ended up using Samsung Spinpoint F3’s from some of my servers. The WD Blacks work fine on Intel ICH Raid. I think next time, I’ll stick with these Samsungs. Cheap, good warranty, and FAST.

Now in general, why can’t Western Digital make standards compliant drives? I could easily blame Adaptec as well, but in this case, i think it has to be WD’s fault. They are known to make ATA drives that don’t work the same way as everyone else. How hard can it be? Even Samsung got it right.

Update, see my second post on this

  1. Hi,

    I just come across your post this morning. I recently had some issue with my 5805 + WD6401AALS-0, the 640GB version of blacks. They used to work very well a few month ago, until I updated firmware. Now, my powr management function is completely trashed. Regardless what timer setting is, the disks will start spinning up 10 min after the spin-down. Have you experienced this problem as well?
