Author Topic: how to find out if external HD uses USB 1.x or 2.x? (Read 17585 times)

Hi,

how is that possible? I have the feeling that it should *not* take almost a day to move 50 GB from one external HD to another. Both drives are what's being sold these days, not old crap.

f0dder · « **Reply #1 on:** April 02, 2007, 05:47 PM »

If you 1.5MByte/s transfer speed or less, the case is running in usb 1.x mode. If you get more than that, it should be running in usb2 mode... how high you'll get depends on a lot of factors, but you're not likely to reach the theoretical usb2 max speed of ~60MByte/s... protocol overhead and other stuff.

I've tested my (relatively crappy) enclosure with multiple drives, and I usually get around 20-30MB/s - and slightly more if I connect with FireWire instead, but I don't trust that because of some data corruption issues.

I wonder if transferring from one external to another is killing throughput. If you have space on a local drive to store the data temporarily, it might actually be faster to copy from one external to the local drive then copy from the local to the other external.

Also, if you have either or both of these drives connected via a hub, move it/them to ports on the PC itself.

I wouldn't be surprised if USB drivers/controllers/hubs aren't very good at dealing with hi-speed throughput to multiple devices concurrently.

Remember to use a good copy utility (robocopy or such) that knows how to do copies with large buffers and overlapped I/O so the device drivers have the best chance of getting things optimized.

However, shoving 50GB of data around will still take some time - I'd guess that an hour is the best possible time you'd get, and that's with all components being top-notch.

brotherS, you can easily check what version your USB controller is by doing the following:
1. Call up the Device Manager.
2. Expand the Universal Serial Bus Controllers branch.
3. If it says "Enhanced USB Controller", then your system is USB 2.0. Otherwise, if it says "USB Controller", then the system is USB 1.1.

i agree with mwb1100, you have to use specialized copy program to do the transfer.. my own personal experience, 40GB in about 20-30mins using xxcopy. btw, microsoft's robocopy (reputed to be one of the better copy programs) now has a gui

Thanks, *that* seems to be the problem :-(

how to find out if external HD uses USB 1.x or 2.x?

The text the arrow points to says device isn't working as it should since Windows can't load the needed drivers.

But where do I find the drivers? I just know that it's an ABIT IT7-MAX2 V2.0 mainboard.

mouser · « **Reply #6 on:** April 03, 2007, 06:05 AM »

make sure you dont have usb2 disabled in the bios -- i reset my bios recently and it turned off usb2 support.

wr975 · « **Reply #7 on:** April 03, 2007, 06:19 AM »

That's a weird combination. I don't understand why you have INTEL and VIA USB on your board. Did you install a PCI card?

It seems a lot of USB ports are working, so perhaps just try using another port?

About drivers. Win XP SP2 usually needs no drivers for USB but you can still try.

IIRC my BIOS doesn't have such an option.

Hmm, no, but I had to replace my mainboard and the new one came with an extension that gives me a front panel for USB etc. Maybe related?

According to what lanux128 said above they are all working on 1.x only now.

Thanks! On both sides I see several drivers, but nothing that says "USB driver". Does the Intel Chipset Driver take care of USB too? And how can I find out which version of it I installed a while ago?

Btw, I'm using Windows 2000.

f0dder · « **Reply #9 on:** April 03, 2007, 08:15 AM »

Via AND intel usb is a typical mix on a P4 system that has more controllers than the onboard the intel chipset offers - iirc i had a mix like that on my P4 systems.

IMHO a specialized copy program won't do terribly much for speed when simply copying one file at a time - the advantages of things like Overlapping I/O has more to do with application logic and maximal use of threads. And if there's multiple simultaneous I/O, well, disk performance is going to hell anyway

I did various tests of file reading methods a while ago, and didn't find any difference in completion speed between Overlapped I/O, normal ReadFile, ReadFile without buffering, and memory mapped files. I did, however, find that memory mapped file access took more CPU time while doing the copy, and that ReadFile without buffering took the least.

BrotherS, try removing the USB controllers then let Windows detect them again.. btw, there are some suggestions here for troubleshooting USB in WinXP and Win2000 also maybe you want to consider a BIOS Update for your motherboard..

-lanux128 (April 03, 2007, 08:58 PM)

Thanks for the suggestions. I can't remove the USB controller since it's onboard. The one USB slot that connects to the front is connected with a cable, but I don't really want to unplug it while the PC is running.

Microsoft's suggestions don't really help (I guess I need the missing drivers), and AFAIK I got the most recent BIOS update already.

f0dder · « **Reply #12 on:** April 04, 2007, 07:49 AM »

I think he meant remove them from device manager, so they get re-detected and drivers get re-installed. That sometimes helps

CWuestefeld · « **Reply #13 on:** April 04, 2007, 01:48 PM »

It's possible to have USB2 and still be slow. There are two different speed modes for USB2: Full and High. "Full" speed, despite its name, does NOT achieve the full speed potential; it's the slower of the two. What you really want is High Speed. Most USB2 devices support this, but some bargain-basement hardware may not.

f0dder · « **Reply #14 on:** April 04, 2007, 01:52 PM »

It's annoying that they chose the confusing "full" and "high" speed labels... but it's probably because there's a "low" speed as well, for mice and keyboards and that sorts, and "full" is the max speed of USB1.x...

thanks, f0dder.. that's what i had on my mind..

btw, i just remembered that sometimes inadequate power supply interferes with the USB controllers. a friend had somewhat similar problems but wasn't able to pinpoint the exact cause until his thumb drive got fried..
