Getting closer. I don't know if you're using USB2 or 3- from your figures I guess USB2.
You can try a different disk on the same (apparently slower) USB connection and on a different one to get some figures to compare with those you've posted.
Now you can see a clear difference -a process of elimination should help you identify USB port/ cable / drive.
I would recommend you only have one USB disk connected at a time while you do this.
Note: clarity in terms: and a useful tip you may already know:
Booted with the M: Drive connected to a different USB lead to the PC (Previously connected to H: Drive)
This is rather difficult to interpret.Why?1. As you know, when a drive is connected to a PC it is normally allocated the next available letter. Without the user taking specific action, external drives are not allocated a fixed letter, nor are particular USB ports.
2. It is possible to effectively assign an external drive a fixed drive letter- provided the assigned drive letter is not in use when that drive is next connected. This is done in Disk Management by reallocating the drive to a specific letter- say W - far from any letters likely to be used by plugging in devices randomly. This is very useful for a backup drive which is connected and disconnected, for example.
Assuming you have not used the method in (2) I therefore interpret your statement as possibly meaning:
I booted with the suspect USB drive allocated the drive letter M connected using a different USB lead which had previously been used for the drive allocated drive letter H.
or
I booted with the suspect USB drive allocated the drive letter M connected using a different USB lead. The M drive had previously been connected to the USB port to which the drive allocated drive letter H had been connected.
