Looking for model numbers for stock drives in certain clones

[defor]

Trying to find the original model numbers for HDD and CD drives used in the following for restoration:
Motorola StarMax 4000 (ideally the 200 MT)
Tatung TPC-5000
UMAX S900 (ideally the 233)
Akia Microbook Power 604e
UMAX C500/Apus2000 (specifically the 1.7gb drive and 8x cdrom

Just need the HDD models for the following:
Pioneer MPC-LX100
Pioneer MPC-LX200
Pioneer MPC-GX1
Pioneer MPC-GX1 Limited

Also looking for the MO drive model for:
Pioneer MPC-LX200MO

The MPC-LX200 looks to be equipped with a Quantum Fireball SCSI 1.2GB drive. MO drive is a 640MB unit, probably made by Fujitsu.

The GX1 is a modified 6100/66, so it'll either be a LPS540S, Maverick 540, or a Fireball 540, formatted as a 500MB drive, as per usual. GX1 Limited looks to have a 1080MB Fireball, like what my 7100/66 had in it when I got it last month.

The LX100 should have a LPS270AT drive installed, if Pioneer used the originally included drive with the LC/Performa 63x machine it's based off of.

The Pioneer MPC-LX100 used a ~500MB Seagate Medalist ST3630A, a relatively low-end drive (the old-school black 4200RPM models with brass mounting rails).
The GX-1 was a Quantum drive, the ProDrive ELS/Maverick in roughly 500-800MB capacity.
The GX-1 Limited was basically the same as the regular GX-1. You may have been able to spec an 800-1200MB Fireball (the original, not the cheap TM models).
The LX200 used the very special low-profile Seagate Medalist ST5 family of drives in ~1GB capacity, typically the ST51080A. Normal 3.5" hard drives don't physically fit. They're rare. You could get increased 1.2 and 2.5GB ST5 drives, but the higher capacity ones were slightly larger so there were fitment issues in addition to the fact that, unlike the earlier drives, they were unreliable.
The MOs in the LX200s so equipped were definitely Fujitsu models. Pretty sure they were just 230s though.

The StarMax 4000 often used the very low-end Seagate Medalist ST31276A (or similar) in roughly 1.2GB capacity. These were the 4400RPM, rebadged Conner drives. They were kinda loud, very slow, and fairly unreliable, but easy to find because they were super cheap.

I've found the Japanese-market UMAX clones (including AKIA) typically used NEC hard drives. These drives were kind of rare outside of Asia/Oceania, and they weren't very reliable, so good luck getting one of those.

I looked for a Tatung clone but never found one so I have no idea what it used.
