SATA to USB connector problem

LowLuster wrote:

There shouldn't be any software required for a SATA to USB Bridge adapter. All the adapter is doing is changing the SATA connection type to USB type. Yes that does include a electronic circuit board to convert from one to the other but once the change is made the signal coming out of it is USB which is Universal.

The AC adapter is only for supplying electrical current to the drive so it doesn't have to rely on the USB port to power up the drive.

I suspect the OPs problem was with a defective adapter and I doubt it would of worked on a Windows PC

Yes your right in your logic(thoughts) but this logic dose not exclude the posablity of such a device being OS dependant or need or lack of need for software. Yes both USB and SATA are Universal but the conversion from one to the other can be atrived in any number of diffent ways some of witch don't need software and some of witch do. Cunnia experince as discribed in there posts would suggest otherwise. There post also suggests the AC adapter is for the SATA to USB adapter "....SATA on the other end, plus AC power adapter." even though such an adapter may not need is.

Yes your suspicion that the OP's problem was a defective adapter is OK but not proof.

I have worked with HardDrives and Controlers scince 1989.

Maybe there is some firmware or driver needed in/by the SATA to USB adapter that IS OS Specific.

Nope.

You know the SATA to USB adapter they have?

No, Repeat NO, USB device is OS dependant. USB is Hardware, a direct line into the Chipset controller.

All USB ports work with OS X, Windows, Linux (any version, build, flavor) and any other OS you can name that runs on the hardware available today.

And you can't prove, and can't show, that any USB device is dependant on any OS.

Plug any properly working USB drive, of any type, or SATA to USB adapter with a drive connected to it into a USB port on a properly work computer, even if it don't have any OS install in the internal drive, and that USB device/drive/whatever will be seen by the BIOS or the UEFI. That is because USB is supported by the HARDWARE and not dependant on any OS.

Do you relay think I don't understand this point?

"USB is Hardware, a direct line into the Chipset controller" It is but there is also protocols used over this and the SATA hardware and protocols are diffent from the USB hardware and protocols.

"All USB ports work with ......................." Do you relay think I don't understand this? Yes all USB device connected to a USB port will work on any mechine.

Any properlly working USB drive of any type or SATA to USB adapter with a drive conn........... by HARDWARE. NO it is posable to make a USB device that will only work with one pice of software or software that will only work with one USB device. Example Qbase is a pice of midi software that needs a USB dongle to run.

What are you talking about. I give up.

Let me check the 100 or so SATA to USB adapters laying around here.......

still nope

If you look at the Function Block Diagram for the JM20337 IC one of the IC's found in the USB to SATA adapters you will find "SATA Transport Layer" and "ATA/ATAPI Controller" these blocks contain firmware amoung other Blocks.

I know what I am talking about.

Yes this device can be used with both Windows and MAC. All I was saying is it has firmware.

USB is not just about HARDWARE

This document is about the information needed to program one sort of USB system (SOFTWARE)

There are no PC or Mac proprietary commercial interface SATA bridges for HD

End of story.

The SATA card inside external hard drives is a nasty stinker of a part, its nature is frequent failures.

Millions of good hard drives are sitting in landfills because of dead SATA cards people wrongly thought were crashed / bad hard drives.

why is why its best use naked HD and HD docks and eliminate the problem (except for cases of a portable notebook hard drive of course).

Either that or JBOD towers

Nice to see other languages but may I ask why the Greek? I know your a translator (from your profile).

I have been looking over past posts and I think there has been some misunderstanding.

I use words like "can" and "maybe" but the two people who have been trying to shoot me down seem to have been answering my post as if I was using words like "IS" and "ARE" as you are a translator I was suppressed to see such a basic mistake. I am dyslex... and have problems with spelling and that's why I chose my words very!!! carefully even if I can't spell them properly.

You make statments like "There are no....." where I would say "I think there are no......" can you see the diffence?

The problem MAY be a incompatablity. That dose not mean the same as "The problem IS a incompatablity" You should know this.

Because the OP Cunnla used Greek, I merely kindly replied to him in Greek.

"There are no....." where I would say "I think there are no......" can you see the diffence?

Semantics, nature and limitations of human communications,

Peace

I have just read the original post and it is not in Greek

In this case the semantics are IMPORTANT because you answer as if I make a absolute statement when I achley made a posable statement. The two are very different!!!!! This means that you gave an replay to something I did not say. This is not right.
