If any hardware works on XP it has a very high chance to work on win10. There are only a few of those which won't work.

Microtech's website does seems to still exist. That said, the website doesn't look like it's been updated since 2000 :). They seem to still have a linked in page as well. Not sure whether they are still trading or not though.

I am not sure why you would entertain installing unknown and very old hardware/drivers on your daily driver rig when you have something else available. That will rarely end well.
Thanks for the memories though. I remember using similar devices in the day.

I think this illustrates a very common kind of problem I run into w/ troubleshooting at work – if I were to create an analogy I'd call it a "lock" style problem.

The problem is solved if you can figure out every aspect of it, just like a lock will unlock if you can get each tumbler in the right position. But whether every tumbler is in the right position or not is only something you find out once they're ALL in the right position. There's no feedback on why it doesn't work when it doesn't work.

I think stuff like this is usually caused by borderline documentation (whether you misread it or it didn't say that you have to set to ID0 doesn't really matter since good documentation would make it stunningly clear that it will not work without setting your scsi device to 0). Often timese we'll have stuff, in particular getting various PLC automation devices to communicate with each other, where it doesn't work and doesn't tell you why it doesn't work and you just have to trial and error test tons of settings until you get the right sequence and it just magically works.

Trying different drivers/older hardware to get it working was like jiggling the wrong tumbler in a lock… it wasn't apparent that it was a non-problem and that it was just a drive jumper setting all along, till you fixed that, and then went back to newer hardware and realized that most of your trouble shooting steps were unrelated to the true problem.

Its why good documentation avoids huge timesinks like this.

the SCSI cable could also have a say in the ID.

For Android your device must have an NTFS driver in the kernel there is also an app called NTFS for USB by Paragon software however the app only provides the driver and you still must use a third party file explorer that supports the Paragon app I recommend X-plore.

I found my old Belkin USB-SCSI adapter recently. I am hoping I can connect a Zip drive and a CD drive and a couple of legacy synths/samplers to my Win10 machine now. IIRC, that particular device can be bus powered, but also has an external power supply.

For all that USB1 is slow for bulk data transfers, it is hugely faster than copying sample data over MIDI.

Windows 7 or newer has very poor parallel SCISI support

Try Linux as a used a USB to SCSI and zero drivers needed as Linux Kernel seems to have better support for parallel SCSI than windows 7 or newer windows

Several jobs ago someone had a no longer working combination of a external zip drive connected to a SCSI to USB adapter in my testing the Zip drive did not work but the adapter was recognized by Windows XP I regret not grabbing it.

Clonezilla reads and writes disks. Either it runs from a bootable CD/USB, or can be installed in Debian or Arch system… but then I use Linux everywhere.

SCSI needs proper termination.
These old drives (usually) need to have cable termination for anything other than ID 0 – which itself is most likely just a fluke it's working. I still have my flat/ribbon cable 50 pin terminators (also UltraWide/SCSI-3 68 pin ones, though I used to have brackets with clip on terminators for those), which were for internal termination, of course if you have an external case, which generally used Centronics plug there also terminators for those. Using the devices as an end point might work, but not recommended. "Provide termination power" is also no equal to termination and "auto termination" can be finicky if not plain unreliable, the closer you get to SCSI-1.

Running SCSI without terminator, especially when it's open like the Syquest (it's just a bus and the open end is flapping in the wind) leads to all kind of strange behaviour: slow speeds (IOMega) , writes not properly working (SyQuest), devices vanishing, device not ready, etc.
It even says it can handle 7 IDs (SCSI-1 & 2), just need to have proper termination, another "trap for young players" (EEVBlog) the controller (which this device probably emulates) has it's own ID in that 3 bit field (often ID7 or ID0), double usage of an ID can lead to non-detected devices at best (even no boot) or strange things happening.

Well I still have my Adaptec (the latest one is a 29160), NCR/LSI and ASUS controllers (even actively use modern HP SAS RAID with RAM, though I use that one with SATA drives) from back in the days when SCSI drives used to be bigger and faster than EIDE, had 8+ GB (IIRC: IBM DDRS) drives before EIDE became ATA and then PATA and UDMA was a thing. Also EIDE also had the problem, before 48 bit LBA came into BIOS, that CHS was just a hassle (no "auto detect", manually put into the BIOS). Also SCSI: no 508 MB barrier, making dual booting easy, even it quite was already with with OS/2's bootmanager.

Concerning "SCSI not main stream": Still have my ASUS PCI/I-486SP3G and Asus P/I-P55T2P4S

SCSI was used on many computers, just not cheap PCs. Off the top of my head, Amiga, Apple, Acorn, Sun, SGI, DEC…

That sector error can happen if you ask to read more sectors than the drive has. Or if a bad sector pops up but I'm doubting because you got a good sized rip.

You can self-sign the driver and enter your own self signed authority to the trust pool and not have to disable signing in general. Just mentioning as I have a bit of a fascination with using old devices on modern PCs – my z390 board I just switched to has serial/parallel headers and I'm stoked, also just added a firewire card. Lol

I've kept a PCI SCSI board and I have a couple of motherboards that still have PCI slots just for this sort of thing, really. It's not as convenient as USB, I know – but it does work, and quite a bit faster too.
