I have an old TEAC: SD-3105-30 105MB 3.5"/SL IDE / AT hard drive that I would like to connect to a Windows 11 computer via USB. Would anyone be able to provide a link to some type of enclosure or unit that would make this happen? I am including photos of the connection and drive details below.

Thank you for your time.

The indicator (LED) on the front bezel lights up while the HDD
executes a command. An external LED can also be lighted through the
-SLV/ACT signal terminal on the same condition by setting the strap
S0 to ON.


Straps
------
The setting method for the straps, S1 and S2, should be changed
according to the number of the HDDs connected as shown in the
following table.


Functions of straps
+----------+-------------------------------------------------------+
| Strap No.| Function |
+----------+-------------------------------------------------------+
| S0 | Changes over the function of the -SLV/ACT output |

| | can be lighted up at the -SLV/ACT signal |
| | terminal. |
| | OFF : The -SLAVE PRESENT signal is selected. |
+----------+-------------------------------------------------------+
| S1 | Selects whether one HDD is used singly, or two HDDs |
| | are used in daisy chain connection. |
| | ON : Two HDDs are used. |
| | OFF : Only one HDD is used. |
+----------+-------------------------------------------------------+
| S2 | Selects the master drive or slave drive. |
| | OFF : Only one unit used, or master drive with two |
| | units used. |
| | ON : Slave drive with two units used. |
+----------+-------------------------------------------------------+
| S3 | Changes over the -I/O CH RDY output signal. |
| | OFF : The -I/O CH RDY signal is not output. |
| | ON : The -I/O CH RDY signal is output. |
+----------+-------------------------------------------------------+
Notes: 1. ON : Strap short
OFF : Strap open

2. At the shipping of the HDD, the strap S0 is set to ON, S1
to OFF, S2 to ON, S3 to ON.

Any of the four directions can be used.
The mounting cabinet for the HDD should be constructed so that no
distortion may be produced in the chassis.
A space of at least 1.5mm must be allowed between the mounting
cabinet and the PCBA of the HDD.


An insulation sheet should be stuck to the PCBA mounting face of the
HDD mounting cabinet, as required.
In each mounted position, the front can be raised by up to 30*.
Mounting positions other than those shown must be discussed
separately.


Screws
------
The HDD is fixed with screws through the mounting holes at the
3-#6-32UNC 4 deep each side.
4-#6-32UNC 4 deep bottom.

Hello, a lot of the drives this old do not support LBA and therefore connecting them through USB is almost impossible. It will not matter what you use since the drive does not support LBA, or logical block addressing. What you would have to do is get a computer with onboard IDE and connect the drive to it, and then you will be able to do whatever you want with the drive. Also, that is an extremely rare model, and I would highly recommend if you have no need for it selling it on to someone like me that finds high interest in stuff like that. I would hate to see such a rare piece like that lost those things are ridiculously hard to come by. As for the power these use, it is a floppy connector for power. Wondering if that drive still functions, a lot of those Teac drives like that sadly failed and are now near impossible to come by. Let me know what you decide to do and if any of this information helps.

Thank you for your informative reply!

I have an old computer that I can connect the drive to - I was being lazy. :) I have tried other USB enclosures and the drive seems to boot up fine it just isn't recognized and I understand why now.

Yep, that is exactly what I have some older drives do. They will show up sometimes, but will never be able to be accessed and report an error, but if you are even able to get the drive to sound ok and it doesn't make any funny noises, it is probably fine and has passed its self-test. Let me know how it goes, I have had quite a lot of experience with older drives and know how some can be a little funny sometimes acting like they are not working when they are indeed fine. Appreciate the reply.
