Cable Select (CS) appeared as an optional component of ANSI standard X3.221-1994 in 1994, the first published standard describing “IDE” (and later known as ATA-1). This also seems to correspond to the availability of drives implementing the standard; for example, Conner’s CFS-210A, introduced in October 1993, doesn’t support it, but their drives introduced ...

You’re running into compatibility issues with very old drives. In this particular case, your drives are new enough to support the ATA “identify device” command (which is how your hwinfo input includes the drive’s names), but there’s something going wrong with the “read capacity” commands. I suspect the reason is that these commands are LBA-based, and your ...

I think I found the main part of the answer by searching through a standards document. IDE connectors have some dedicated and re-purposed signal lines specifically for DMA. Some of these stay asserted for as long as a DMA transfer is in progress, allowing the other device to see when a DMA has finished and thus when new commands can be sent by the host. [1] ...

The easiest way is to get an external USB enclosure or USB-to-IDE adapter. IDE-to-SATA adapters exist, but they require opening up your computer to install. When selecting hardware, keep in mind that IDE (PATA) hard drives come in two common varieties: "desktop" (usually 3.5" form factor, with a 40-pin data cable and a 4-pin power cable), and "laptop" (...

The controller shouldn’t cause problems, because the interface is largely backwards-compatible — so unless you have a drive which doesn’t quite adhere to the “spec”, it should be able to talk to the controller. (There wasn’t really a spec for the first IDE drives, so take that with a pinch of salt...) What will cause problems in anything vaguely recent (...

The hard drive is so old that it pre-dates the era of auto-detecting the drive parameters. If the USB adapter cannot determine the correct drive parameters automatically then there is no way to force the parameters. Connecting it to a PC where you can manually set the drive parameters in BIOS is the fastest solution. The standard drive parameters should be ...

A proper ISA IDE interface is quite simple, but not as easy as it might sound. There are some strange corner cases you should consider for full AT compatibility. You can find schematics for ISA IDE interface adapters in service manuals of computers slightly newer than you MFM portable computer. For example, check volume II of the Compaq Deskpro 386 technical ...

The Amiga A4000T is the only Amiga to include both a SCSI-II controller and an IDE interface on the motherboard. And, if you can believe the entry in the BBOAH is also THE RAREST home computer ever, with only ~35 known to exist. Note: This is referring to the units manufactured by Commodore, and not those that followed the bankruptcy. Anyway, she's a rare ...

@Justme has covered the topic of drive detection, but since the question is requesting "next steps" for data recovery I'd like to speak to reading the data once your hardware is able to "see" the drive. As you have access to Linux, I highly recommend using GNU ddrescue for reading the disk especially given its age. ddrescue will create an image of the ...

A laptop of the vintage you mention will most likely have a 2.5-inch IDE, PATA (Parallel ATA), hard disk drive. Of course, you will need to disassemble the laptop and remove the drive to confirm. Once removed, you can obtain a low-cost enclosure, such as this one from amazon, to connect the drive via USB 2.0 to a more modern computer. Most likely, the FAT ...

The Amiga can support multiple mass storage controllers, subject to the following necessary limitations: Any time multiple controllers are using AutoConfig, each controller must correctly support the AutoConfig protocol. This means it must pass the token to other controllers on the bus so that each controller gets a chance to configure itself. Each mass ...

It looks I got lucky, otherwise it would have been a long road. Apparently this laptop has a ROM-DOS on board in the socket. Due to bad contact it was not detected at startup. After I reinserted flash chip into the socket, it detected it and booted from ROM to DOS 3.3. It only had FDISK among useful tools there, but that was enough. It appeared, that BIOS ...

After some more digging I actually found the card on stason.org: http://stason.org/TULARC/pc/hard-disk-floppy-controllers/I-L/INFOMATIC-POWER-SYSTEMS-CORPORATION-Two-IDE-AT-Int.html The layout and jumpers match exactly, even though it is listed under a different manufacturer.

This document should tell you all. These jumpers configure state of the multi I/O card devices, and their port locations. The document states different chip UM82C865F, but the jumper functionality should be the same or similar. At the end of the day you can figure out yourself. Update: I found datasheet of the W83757 on the alldatasheet.com; there's some ...

My condolences. You can hook up that (assumed) ATA harddisk using an appropriate USB adapter (you'll need the 44-pin type for 2.5" drives, thx Brian) - many electronic shops still stock ATA/SATA-to-USB adapters.

I bought a IDE to USB converter from a local store.There were two extra pins on my hard drive so I had to do some fiddling and connect the AC power supply I connected the adapter to my Linux laptop (also works on Windows) and I could see the files stored on the FAT32 filesystem. The disk is almost full (The thing is 4GB and has 100MB left , my laptop has ...

SGI was one of the leading vendors to put a modern touch around X/Motif. IRIX came with ViewKit and OpenInventor, plus some SGI-specific libraries to handle desktop integration, all part of SGI's DeveloperMagic development environment. To enable developers to build a fully IRIX-Integrated application, SGI provided a whole landscape of C++ libraries and ...

From another good answer: "Connecting it to a PC where you can manually set the drive parameters in BIOS is the fastest solution." Hint for finding such a PC: The facilities to manually set such parameters in the BIOS setup will often be present in mainboards that are equipped with ISA/EISA slots. Such boards still physically supported some ancient ISA/EISA ...

How to build an ATA controller for the AT bus? You can't, as there isn't any. You want to connect IDE-Drives, right? IDE stands for Integrated Device Electronics. Which simply means that the full host controller is already part of the drive. It contains everything that is on your MFM controller, except for bus-buffering, address selection and extension ROM. ...

Buy IDE to usb connector and see if it boots? Close, but not quite. Do not try to boot the drive. That will almost certainly not work. What you want to do is simply read the drive on a new computer. The act of simply turning on the drive could cause problems. No guarantee. But my hunch is that it will either work OK (in which case, you copy the files as ...

If you are mainly concerned about successfully recovering the data, then the safest route is to hand it over to a trustworthy data recovery professional. They will have more knowledge and tools at their disposal to be successful than you will. Alas, you say this is your "last resort"... Option #2 is not unreasonable. USB-to-IDE adapters are inexpensive and ...

I think you did a good job of providing relevant details. For instance, the fact that the same image works on a newer machine does indicate that the critical "system files" (IO.SYS and MSDOS.SYS and perhaps the command interpreter, typically COMMAND.COM) may all be in the right locations on the disk (referring to disk sectors, not just filesystem hierarchy). ...
