copy large file to USB drive hangs

[Guest flahmeshess]

Re: copy large file to USB drive hangs

 

When you say 250MB to 500MB, are you referring to file size or the

total number of bytes ? My files are > 500MB or > 1GB.

 

No yellow or red error warning marks.

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]

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.

I found a USBStor in driverguide. I tried to see if by replacing it

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. This would explain

yours working on one box and not another. Try a power adapter or a

powered hub and see if it works.

You don't need to update it. Win2k provides all the generic drivers for

your device.

No. I have Win2k. 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.

[Guest flahmeshess]

Re: copy large file to USB drive hangs

 

Device Type: Storage Volumes

Manufacturer: Microsoft

Location: Volume Manager

 

Driver Provider: Microsoft

Driver Date: 11/14/1999

Driver Version: 5.0.2183.1

Digital Signer: Microsoft Windows 2000 Publisher

 

There are 3 buttons. The Driver Details is blanks out. So I cannot

click on it. I can click on Uninstall & Update Driver.

 

How the above ? Any problems ?

What details are you shown in DM under Disk drives, when you click on

the drive, and are the manufacturers shown for your all HDDs? Is USB

device shown as 'working properly'? Have you checked 'Properties' (click

My Computer/Drive letter for USB drive)? Is the correct disk capacity

correct?

Re: copy large file to USB drive hangs

 

Hi Frank

I just checked my office machine. It also says "Volume Manager". I

tried copying to USB but I didn't have this problem. I will go back

and check the PC for the other questions you raised. Thanks.

- WDC xxxxxx

 

When I click on my Samsung drive, I have:

 

Device type: Disk drives

Manufacturer: (Standard disk drives)

Location: 0

 

When I click on my WDC drives, I have

 

Device type: Disk drives

Manufacturer: (Standard disk drives)

Location: 0 (0)

 

In Computer Management - Disk Management,

 

The capacity is 232.88 GB. It's a 250GB USB Drive.

 

Any problem with the above ?

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.

So Win2k is correctly identifying your USB drive?

Not that I can see from what you've said. 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]

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.

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.

"I've done some checking and found there is a problem with Win2k that is

fixed in SP2." What do you mean by this, then?

 

"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?

I also should ask as you say the Samsung is self-powered, what is its

power requirement? See spec or manual.

[Guest flahmeshess]

Re: copy large file to USB drive hangs

 

My machine has the latest fixpack. When I do a update at Microsoft

website, there is nothing to update.

I installed the software for chipset. Sorry about it. I didn't

understand the different then.

I've tried the different USB ports and the same problem occurred.

Motherboard is Asus P5BE-Plus.

 

There is not fixed size. But I found the problem when the files are

large, ie > 500-600MB.

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.
