SATA II on SATA I ???

[mxsi64]

This is my mobo http://h10025.www1.hp.com/ewfrf/wc/genericDocument?lc=en&cc=us&dlc=en&docname=c00063272 I want to know what happens if i connect a SATA II drive on the SATA I port, because there are almost only SATA II drives at reasonable prices in the market, can I put a SATA II drive here until I upgrade? Will it work with no secondary effects?

Thanks

Yes you can, but check the hard drive documentation and it will tell you what jumper to apply to make it backwards compatible.

There are no jumpers on SATA.
And unless your boards SATA II, it won't work.

Ignore what Tom said and see my 1st post.

Show me a Sata II hard drive with jumpers on it and I'll agree with you 100%. I own 6 from different vendors and not a single one has a jumper on the hard drive.

Where did you find THAT infomation? Many SATAII drives ARE backwards compatible. Sometimes it depends how good your motherboard SATA controller is at negotiating. Other drives have a jumper to forse SATA 150 compatability.

Exactly Mike...

Sorry Tom but just cause yours don't doesn't mean they aren't out there.

Yes each sata hdd has a jumper built onto it. This is to enable the sata2 to become sata150 but still sata2 will work on a sata1 mobo with the jumper set to sata2.I've tried this myself

Probably most do, but I have a mobo, the Asus P5PE-VM where i had to enable the jumper for my SATA2 HD for backwards compatibility to work.

With the exception of the VIA 8237. That thing simply cannot play nice with a SATA2 drive that lacks Sata1 compatibilty jumper, which is why I only recommend Western Digital Sata2 drives if you need backward compatibility, as they have the sata1 jumper.

There are no jumpers on SATA.

I own two SATA drives that you need to move the jumpers around just like a ATA drive.

A SATA2 drive will also work on any MB that supports SATA or has a SATA card installed.

Just to point out one big fact....tho you see alot of "SATA2" HD/MB being sold there is NO such offical computer standard.

my seagate drives by default are capped at sata1 speeds till i change the jumper settings to allow sata2, the wd drives will clash with via and sis chipsets unless forced back down to sata1 speeds (on older boards anyhow) and both the formats are otherwise totally compatible 😉

As ZOldDude and others in this thread have stated, SATA works as follows:

1. There is no such thing as "SATA I" and "SATA II". SATA is one set of standards. All drives labeled "SATA" are members of that one standard.

2. SATA drives can optionally implement several features in any combination. These optional features are:

- 300MB/sec transfer rate instead of 150MB/sec transfer rate.
- NCQ (Native command queueing)
- eSATA Compliance (ability to work at voltage signalling levels for eSATA operation)
- Hot Swap (ability to respond to hot swap commands from the controller)

3. All SATA drives are supposed to operate on all SATA controllers, regardless of the feature set of either the controller or the drive. Thus, a SATA drive that implements 300MB/sec transfer rates is supposed to operate just fine on a controller that only supports 150MB/sec transfer rates (albeit at 150MB/sec speeds).

There is an exception to this rule: There are some older SATA controllers that do not properly perform the feature negotiation with the drive. In this case, the drive will often operate at it's highest capable speed (for most modern drives, this is 300MB/sec) which the controller likely doesn't support. The speed mismatch between what the drive is operating at and what the controller is operating at will cause problems. The following south bridge chips are known to have this problem:

Via VT8237
Via VT8237R
Via VT6420
Via VT6421L
SIS 760
SIS 964
Intel 82801EB (ICH 5/5R)

Therefore, drive manufacturers have implemented a jumper on all SATA drives that are capable of 300MB/sec transfer rates, where that jumper will limit the transfer rate to 150MB/sec operation.

The following pages will show you the correct jumper settings to force 150MB/sec operation on your 300MB/sec SATA drive should you need to connect it to one of the above south bridge chips, or any other SATA controller chip that is incompatible with the negotiation process:

Seagate SATA Drive jumper configuration
Maxtor SATA Drive jumper configuration
Western Digital SATA Drive jumper configuration
Samsung SATA Drive jumper configuration

Hitachi produces their drives without speed-selection jumpers. They may have problems on the above-mentioned chipsets.

 

[tomwaddle]

I stand corrected.
So, with that being said, if the OP buys a new SATA II hard drive with no jumpers on it, are you guys saying it will work?

 

[Spikke]

It should work. When you plug a SATA 3 hd into a mb that only supports SATA 1.5 it should automatically revert to SATA 1.5.

Oops, forgot to look at the link of his mobo. 😳

Your drives are actually capped at less than SATA speeds, in fact they are probably capped at 90MB like most 7200 RPM drives.

there not capped, thats the physical limitation of the technology 😉 - moving parts and heads cant keep up with the rest of the system
