XTA isn't the same thing as ATA with 8-bit transfers selected; the registers and command set are different. Bit serial data interface introduced by CDC Standard interface for many mini-computers in the s and s. This article's use of external links may not follow Wikipedia's policies or guidelines.
Although the connector pinouts are very similar, the A2 pin is missing on the XTA interface--it's ground instead.
The earliest hard disk drive HDD interfaces were bit serial data interfaces that connected an HDD to a controller with two cables, one for control and one for data. Page 1 of 2 1 2 Last Jump to page: All times are GMT Comparison of disc image software.
In bit serial data interfaces the data frequency, data encoding scheme as written to the disk surface and error detection all influenced the design of the supporting controller. Since a lot of AT IDE controllers included a floppy controller, this might be a way to get high-density floppy capability along with hard disk ice the same card.
Bit serial data interfaces introduced by Seagate Technology beginning In any case, since you'll be patching for the edsi code, you could probably patch the rest fairly easily.
Enhanced Small Disk Interface
Retrieved from " https: As for all early interfaces above, each drive also has idw additional power cable, usually direct to the power supply unit. ESDI disk drives typically also had jumpers to set the number of sectors per track and in some cases sector size.
Korpi, Electronic Design, August 20,pp. Please improve this article by removing excessive or inappropriate external links, and converting useful links where appropriate into footnote references. Idd, it sounds like work Thus each time the internal technology advanced there was a necessary delay as controllers were designed or redesigned to accommodate the advancement; this along with the cost of controller ezdi led to the introduction of Word serial interfaces.

Well, you can patch your hard drive BIOS to issue the following command sequence: Disk drive interfaces have evolved from simple interfaces requiring complex controllers to attach to a computer into high level interfaces that present a consistent interface to a computer system regardless of the internal technology of the hard disk drive.
It occurred to me after a couple of posts that many people with XTA 8-bit Esdii controllers aren't aware that most most CF cards support 8-bit transfers. Disk image file formats.
Enhanced Small Disk Interface - Wikipedia
Join Date Apr Posts Each drive also has an additional power cable, usually direct to the power supply unit. So I took my year old drive sniffing program and modified it to tell you if your drive will work in 8 bit mode.
I suppose if an XTA controller decoded the extra address bit, or you could "borrow" it from somewhere, you might stand a chance at getting the thing to work. At least companies, see List of defunct hard disk manufacturers.
Hard disk drive interface
What I propose is a way out of the conundrum of dead XTA drives on gear where replacing the controller isn't desirable or possible. From Wikipedia, the free encyclopedia. I'm still working on CF too.
January Learn how and when to remove this template message. I suspect this is because that the old XTA drives just worked in 8-bit mode by default, but CF cards and ATA2 drives need to be told to get into 8-bit mode. The time now is
