Windows 7 can't detect more than 7 internal hdds

[GuyzNexDoor]

I've install 8 hdds in 2 of my pcs which are running on Window 7 ultimate 64 bit. I juz realize that compare to vista ultimate 64 bit, windows 7 can't detect more than 7 internal hdds. I thought at 1st, it was something related to PSU or maybe the mobo bios, so i updated my giga bios till the latest one i.e f13a, than try using power connecter - sata converter to make sure the sata cable not really under stress. But still not working. But since 2 of the pcs facing the same problem, i conclude that windows 7 can't detect more than 7 hdds.

Would really appreciate if someone who manage to make windows 7 to detect more than 7 hdds, give some advice to me here. BTW, the hdds must be internal, not external one.

Thanks a lot in advance.

Um, exactly how are you connecting all of these HDDs? There aren't many motherboards with 8 SATA ports that I can think of.

Are you using a separate RAID card, or port expander? If so, it could be a driver issue. I put a new SATA RAID card into my machine yesterday, and no drives until I updated the RAID card's BIOS, then the driver was properly detected. It works fine now, but some of the older cards don't come with a Win 7 compatible BIOS. I had to download and install the ones for mine.

Thanks for ur reply. I'm using Gigabyte EX58 Extreme motherboard, got 10 sata ports. So 8 of the ports are for my hdds, the other 2 for dvdrw and casing usb front port respectively. BTW, i'm not using RAID or run my hdds in RAID. Juz run them as a separate hdd coz i'm not really into performance type, but rather to have as bigger space as i can

Sorry man. In that case I don't know. My system can have a drive for every letter in the alphabet. Problem is, I only have six ports. I have mounted up to five extra temporary virtual drives with drive letters, but that's probably something different entirely.

Your storage is 6 + 4: 6 SATA on the ICH10R controller and 4 on the Gigabyte GSATA controller. Do you have the driver for the GSATA updated?

Thanks man... Though i'm not running on RAID, i tried to install the RAID driver for Gigabyte GSATA Controller and it's works Weird enough coz without the driver, 3 out of 4 Gigabyte GSATA ports are working perfectly. I mean as long as u don't install more than 7 hdds, u won't face any problem.

Thanks a lot everyone.
