Is > this outdated ? From your earlier post you clearly have your PC configured for USB2 which is compatible with USB devices. Your drive will only makes use of USB, not USB2 as that wasn't around then, so it's a much slower device. You should see 'USB mass storage device' under Device Manager, when it's plugged in. Double click just to make sure it's shown as working properly. You should also see a separate category 'Storage Volume' which is your listed USB device. Check that this is also working properly and whether Device Manager can actually show the actual name of the manufacturer of the device in 'location'. Also ckeck that the device has been digitally signed when you look under the tab 'driver'. Finally, r.click My Computer/Manage/Disk Management. Check that the drive is shown correctly (when connected), particularly its size is being seen by Win2k and correctly described.
Guest flahmeshess Posted March 21, 2008 Posted March 21, 2008 Re: copy large file to USB drive hangs My USB is 2.0 and my drive is also USB 2.0. I don't see a "Storage Volume", is it because I'm using Win2000 ? The drive is correctly sized.

Guest Airman Thunderbird Posted March 22, 2008 Posted March 22, 2008 Re: copy large file to USB drive hangs Some USB ports don't seem to perform up to spec on particular computers, IME, as to the power requirements of the USB drive.

How does Device Manager describe your device? Does it tell you the manufacturer, whether the device has been digitally signed? The best way to tell is unplug your device, look at DM, then plug in the drive, and see what extra device description is seen. Mine shows up as 'Storage Volume' with 'Generic Volume' sub-categorised. It's within that category that DM gives the full description of the device with a correct description of driver provider (in my case Microsoft). It's also seen under the 'Disk Drive' heading with a correct description of the manufacturer. You should not need to download any extra drivers for the device. Win2k SP4 own generic drivers should suffice.

Is the correct disk capacity > > correct?- Hide quoted text - > > - Show quoted text - I am experiencing the same problem. Win2k, SP4, External USB enclosure w/ 400Gb HD. As part of my backup strategy, I copy 6 or 8 4Gb+ files per night. After about a week, the USB drive hangs with the red light on, and I can't bring up My Computer or Windows Explorer. I can't even reboot. The whole system just hangs when it needs to access any of the drives. If I turn off the USB drive, I get the same errors you referenced, and I can then get to my other drives and reboot. I have no problem backing up the files on the USB drive to tape. Reading the files appears to be no problem. It only hangs during the creation of the files. In the properties of the USB Mass Storage Device line in Device Manager, my drive shows as Location 0 (Cypress AT2LP RC42) and is working properly Under the Disk Drives section of DM, it shows as ST340063 3A USB Device, and again is working properly. In the Logical Drives section of the Computer Management screen, it appears with the correct size. Let me know if you find a resolution to this issue, or if there's any other information I can provide to you that may help. Joel

The key seems to lie in the fact that you initially reported you could transfer without a problem with Win2k SP2, but not SP4. Clearly then it cannot be a hardware problem with your PC or USB drive, but there must be a flaw with your upgrading to SP4. Did you include the updates to SP4 particularly Rollup 1 as well as well as the other hotfixes to SP4?
Guest flahmeshess Posted March 27, 2008 Posted March 27, 2008 Re: copy large file to USB drive hangs Hi Frank Yes. Win2k is correctly identifying my drive. I think it's a miscommunication, I did not try this at SP2. So I don't know whether I had this problem in SP2 or not.

Guest flahmeshess Posted March 29, 2008 Posted March 29, 2008 Re: copy large file to USB drive hangs I beginning to think that the USB is not able to handle the throughput. If I find ways and means to slow down the copy, then it will be able to copy more files before hanging or is able to copy all across. So I wonder if there is a copy program that can specify the write buffer and specify a wait time before each write. Just hoping for a ready made one. Thanks.

"Then I went to the device manager and changed all the USB drivers to Intel." How? You can't do anything like that trhrough DM. Windows 2000 provides its own drivers to run USB when you either install or upgrade it. Intel only provides the chipset drivers so that all hardware, buses controller devices in your PC can communicate with it. Ideally chipset drivers (the correct one) should be the first thing to install after the operating system. You didn't say whether you had all the updates to SP4 including Rollup 1. Assuming that you have, all I can suggest is that it's possible there is a resources conflict. Have you tried using any alternative USB port? What is the motherboard in your PC? Can you copy any files and if so what is the maximum size before failure?

See spec or manual. > > I've looked up your Samsung model and I see it's a SATA drive, not a USB drive. So I'm confused. I can only assume that you are using a caddy with USB connectors to use it as external drive. Please confirm. Secondly all motherboards have a USB hub 500mA output current. I haven't checked the spec yet for your mobo, but I would assume it's the same as this is standardised. If that's the case I suggest there is not enough current alone from the USB port on your PC to power your Samsung. That is why some USB external drives are self-powered rather than rely alone on the current from the PC hub.
