Large file transfer stops working when using USB hard drive and Windows 7 64 bit, Intel chipset

Well I get sick with this large file copy issue that doesn't go away 

I tried the bits of ideas shared here and it didn't work

I have a Dell 1705 and Toshiba Satellite ...  thermatake BlacX Duo USB2 ... WD20 - 2 TB Drive ... been through this problem since Vista ... problems copying large vmk files over to USB ... like 9.6gb, 13.3gb, etc

Well I check other similar treads ... I figured out my issue ... when I read something that made me think ...

The file I had a problem with the vmk's ... It appears that inside VMware disk file there is already files compressed in there. I don't think it matter if the file sat compress or regular on the outside.

My system would go crazy locking up, source file stops reading, system still trying to write something ...

I read somewhere that some compress files ... would complicate copying

so the lesson learned ... don't used compressing so much ... use it wisely

I guess MS doesn't really up keep their compressing routines ... unlike in the old days of DOS ... there were two principle compressing vendors ... now they are gone because of MS doublespace ...

I hear that as MS moves to a different drive format ... compression will .. cease to exist

It appears the this old compressing routine is the reason why VMWare stress that you should not run vmk compressed on the drive or it will lock up ... now I see the source of why .. without running vmware ... its ms waiting to deprecate sw that's prone to issues that takes away manpower to advance their vision

I hope this little insight helps any one with large file copy issues ... remember remove the compression on the drive or directory to where your copying

good luck

Though I was not running Acronis True Image, I did have the "Acronis Drive Monitor" for monitoring the SMART status of my internal drives.  This appears to have been causing the copy problems.  I removed Acronis Drive Monitor, just to see if this Acronis product was causing me the copy problems on Windows 7 SP1 x64.  After removing the software and rebooting, I was able to use my USB drive without any problems.

Good to know I'm not the only one that's been getting this.

I first noticed when I got curruption in HD Video files and so started checking the source and copies etc and discovered the MD5 hash didn't match etc.

The only nVidia motherboard I ever had I had problems with the hard drive controllers and certain drives needing Native Command Queuing disabling otherwise it would currupt the HDD's. :p

It's strange that Microsoft believed that this issue was an nVidia related issue when it seems to be much more routed in the OS. I'm not a software engineer (although I am a Systems Engineer) so I could only guess at the cause but it deffinatly seems related to Windows 7 x64 and 4Gb+ RAM. It's clearly not an issue with just nVidia USB controllers as I have Intels on both "issue" machines and also one has the NEC PCI card in too and that had the same issues. I am wondering if it's some buffer that is bigger when you have more RAM and so affects the larger files that might fill that buffer when it gets currupted.

I just can't point the finger at the USB enclosures cos I have so many and they all do it.

Hopefully Microsoft take note and look into this. It's extremely important nowadays to fix this as more and more people will be using x64 Windows 7 and more RAM not to mention the increased file sizes now we have HD Video etc.

OMG !!! That worked for me :D

I have an Acer Aspire 5920, bit old I know, as well as a WD external usb drive and I was experiencing the same issue !

I had a similar problem. I fixed it by right clicking on the USB Drive icon within My Computer (Vista), then selecting Properties, Tools and running Check Now to automaically fix errors.

Hope this helps.

Hi,

I have exactly the same type of Laptop as you and exactly the same problem as you!

I think that this is hardware issue rather then software.
