last week my celeron 500 laptop decided to practice suicide, so i took the 2.5" hdd out of that, and yesterday i bought an external usb2.0 hdd cage so i can go around with 20gb in my pocket. now, let me introduce my problems with this hdd cage.

i have a usb2.0 compliant mobo, the kernel has evertything he needs but.... this drive is incredibly slow (i'm tranferring rite now at 1.2M per second).

how can i check that my hdd is actually using the 2.0 protocol???? this drive was not brutally fast on my laptop, but, not even so slow.....

this is my fstab record:

I may also be wise to check if the USB 2.0 device you're buying supports the high speed features of USB 2.0. The thing is, a lot of companies that produce USB gadgets claim "lightning fast transfers with USB 2.0!" but that doesn't really mean anything. A USB 2.0 device is not any faster than a USB 1.2 device unless it specifically adheres to the "high speed USB 2.0" standard.

That's the trick right there - they are claiming "lightning speed" but not "high speed USB" so they can fool anyone.

and, i'll tell you something more. Actually it happens that somethimes (while writing big files) the drive gets stuck, the led on the box is green [green = on, orange = on && (R || W) ].
i can't even ear any sound! and gkrellm tells me there is no R/W activity goning on....

in windows 2000, on a usb v1 machine, it works great! fast and smooth! file transfers are really constant, on my gentoo they got peaks...
