WD3200JS SATA2 working CHS

[winnetou222]

Hi! I purchased my second WD3200JS two days ago, because I already had a same one. So I decided to connect them in RAID, but before that I tried them separately. Both drives are working fine, but the new one (WD3200JS-60PBD0) is set by the BIOS for CHS, and recognized as only UDMA-5. The old one (bought 2 months earlier, WD3200JS-00PBD0) is working LBA, and UDMA-6. My MB is ASUS A8N-E, and I don't know why is the difference. Tried connecting the drives on SATA connector in every possible way, but the situation is the same. Tried some HDD tools for setting the UDMA speed, but for the second drive every one determines the UDMA-5 as maximum. I didn't try the RAID 0 yet, it would probably work, but I don't understand why are the two identical drives recognized differently. Both drives perform equally, it is not a problem.

Any ideas?

Actually drives are different. Same capciy , likely different firmware, one made for OEM and other is retail package.
Can you try to put to Autodetect or force to LBA in BIOS?

I have the same problem with my WD2000JS's. Never found a fix for it, but both are working great in RAID1 currently.
