Windows 7: Corruption In Large File Transfers To USB Drives
Feb 11, 2011
I have moved to Windows 7 Ultimate x64 for almost half a year, recently my hard drive was getting full and I decided to move some of the data to usb external hard drives. Both the externals I have are IDE hard drives and both are NTFS. I always use Quicksfv to make a CRC check file before I transfer the file and then run the CRC check after its been copied over to the external drive. I have used these externals in the past with Windows XP and had no problems.
However, on Windows 7 when transferring large files (usually over 1GB in size), I get corruption in the files. The corruption occurs randomly, if I recopy the files again it might be corruption free. This only occurs when copying files from internal to external, if I copy files from the external to my internal there's no corruption at all. I have tried changing the usb cables, power cable of the externals, using different usb ports but none of it helped. I scanned both externals with chkdsk and I used memtest+ for over 24hours and all the tests passed fine.

I have several USB 3.0 external hard drives and they all seem to exhibit this problem. First, I had a Western Digital MyPassport SE 1TB with USB 3.0. Transfers of 1GB or less are usually fine, but once it gets higher than that, the drive disconnects. It disconnects before the transfer is complete, usually disconnecting about 5 seconds after transfer begins. I thought something was wrong with the hard drive, so I had it RMAd. New drive came back and still didn't work.This year's Black Friday gave me a Western Digital Elements 1TB also with USB 3.0 capabilities.Same as before: files bigger than 1GB will not transfer. And yesterday I was graced with a Western Digital MyPassport 2TB but unfortunately the same problem occurs.
For all of these drives, I can transfer large files through USB 2.0 connections, no problem. I would be happy with this but... I was really looking forward to using my computer's USB 3.0 connection for the faster speeds. I've tried updating drivers for the port but I still have the problem. Does anyone have any suggestions?Here are links to the hard drives:Western Digital MyPassport SE 1TB (mine was new): Newegg.com - Refurbished: Western Digital My Passport Essential SE 1TB USB 3.0/USB 2.0 Black Portable Hard Drive WDBACX0010BBKWestern Digital MyPassport 2TB: Newegg.com - Western Digital My Passport 2TB USB 3.0/USB 2.0 Portable Hard Drive WDBY8L0020BBK-NESNWestern Digital Elements SE 1 TB: Newegg.com - Western Digital Elements SE 1TB USB 3.0 Portable Hard Drive WDBPCK0010BBK-NESN
Here is the link to my laptop: ASUS - Notebooks- ASUS U46EI have the i5 CPU and Windows Home Premium.

is there anyway to limit file transfer speed on the local area network (not the wan port)? I have a tv tuner farm on my server wich I use to stream live tv to other computers on network. Problem is when I start a file transfer it maxs my connection leaving tv unwatchable. I am running windows 7 hp and have a wired gigabit network

Recently i've run into an issue with a particular boot file or driver "wdf0 1000.sys" getting corrupted. The first time I didn't know what caused the issue due to start up repair not working, so I did a clean reinstall of Windows. This time I backed up everything luckily, because sure enough it happened again, but this time I was able to see the problem. I want to know if there's a way to prevent that driver/file from messing up, because it will be a real annoyance to have to restore my back up over and over again.

Started experiencing playback lag on most movies that were stored on my E Drive which is a 500gb western digital, taking a movie off that harddrive and placing it on my C drive(150gb WDraptorx) sometimes would hang during the file transfer for 10 minutes then start up again. playback would be smooth if played from my external or main c drive , so i thought this could be my E drive was failing, so i tried a disk check over night but was only 10% when i got up and didn't seem to be moving at all.1week later i get a BSOD and freezes for 15 minutes so i did a hard reset, freezes on loading screen for windows and BSOD once again, once is started up in bios got windows is missing a certain file and prompted me to system restore and was freezing every couple of minutes but completed successfully. 2 hours later i get BSOD and BIOS reports the C drive as BAD. did a check disk for it and had a ton of unreadable sections but it completed, haven't been able to get back to windows since. ATM am trying start up repair but its already on 2 hours +.Should i take the main drive out and install windows on to my secondary or is it possible that they are both failing and should just purchase a new hard drive.

My old hard drive sounds like it is about to die. So I am wondering, once I install my new HD (format and install windows) will it be possible to hook up my old HD and transfer the files from it to the new HD? I am using Windows 7 and both drives would be SATA.

I am running two windows machines, 7x64 in a LAN using Groups. They both have static IP's. If I transfer a file from one machine to the other, the rate is over 100MB per second which is very good. Going the other way, it slows to only 16KB per second.PS: Firewalls and AV turned off.

My Linksys WRT120N router no longer works, so I bought a D-Link DIR-655, which has Gigabit ports.I have a PC with Win 7 64-bit with an Atheros L1 Gigabit Ethernet built in the motherboard, an ASUS P5B-VM SE. I also have 4 GB of RAM and internal hard disks connected via SATA 2. The PC is connected to the router via a Cat 5 cable with the label "Type CM24AWG UL E188L30".I also bought a Buffalo Linkstation Live LS-CHLV2 NAS with a 2 TB HD, and it's supposed to have a Gigabit port, too. The NAS is connected to the router via the Cat 5 cable included with the NAS.I checked the settings of the Atheros, and it uses "auto" for the media type (other choices range from 10Mbps Half Duplex to 1000Mbps Full Duplex. The maximum frame size is 1514 (the default), and the receive and transmit buffers at 256. There is no "jumbo frame" property in the configurations.The NAS only has frame size for the configuration, and it's currently set at 1518 (the default). Other options are 4102, 7422, and 9694 (all labeled as "jumbo" frame sizes).
I ran LAN Speed Test from the PC with a folder in the NAS as the destination, and the results for a 100-MB file are 34 Mbps for writing and 71 Mbps for reading.I experimented by setting the Atheros media type to 1000Mbps Full Duplex and the maximum frame size to 9694. I went to the NAS and set the frame size to the highest, 9694. The transfer speed became worse.I could not find any settings in the router except for MTU for Internet connections, but I think that's not used for network file transfers, so I did not change it (the default is 1500).I would like to know if the system and components I have are supposed to be enough to do file transfers between the NAS and the PC that are faster than the results I've gotten.Also, is it necessary to modify Ethernet configurations?Finally, I do not what else to do except to do the LAN Speed test using the ff. options:
1. connect the NAS directly to the PC
2. connect to another PC, probably a laptop, that has Gigabit ethernet and is connected to the router
3. buy two cables that are identified for Gigabit networks and to replace the ones connecting the PC and the NAS to the router

My windows 7 system does not boot probably because of file corruption. Recovery console(repair) cannot fix system to boot and cannot tell what is the problem. I have a OEM installation disc(Premium x64, bought from shop no withing machine) and it seems that I should be able to boot system if I want to start upgrade install. I would like to repair system and preserve installed programs. The problem boot disc can be read and write ok when it is installed on other system. Is there any way I can repair my system?

I have Win7 on NTFS, Ubuntu 10.04 on EXT4 and a third partition for general data with both operating systems can access.The third, shared partition is in FAT32.I have had this set up for years with no problems. Recently, I have found that files that I use, move, etc on my Ubuntu sometimes become corrupted. It is very occasional but is occurring more regularly. I use many files (obviously) but only a fraction of those appear to suffer with the problems. The files are generally left irrecoverably corrupted. It is only files that are stored on the shared FAT partition that become corrupted.All partitions are on the same drive.
To solve the problem, I reboot into Windows and sometimes CHKDSK does it's thing and sorts it all out. However, when CHKDSK does not run, the files are irrecoverably gone. CHKDSK says there are orphaned files, removes and recovers them. Sometimes, a file which has been deleted on on Ubuntu may then cause CHKDSK to scan, find and remove the file (or more particularly, sets all affected sectors to null). I can't quite place the error. Possibly in a ageing and failing Hard Drive? The Laptop is circa 3 years old-ish. I would say that combining file systems is an invitation for trouble - but genuinely I have never had any problems with it before. Sometimes I access Ubuntu when Windows is suspended which I feel may cause Read/Write collisions at OS level but if that is the case, surely it should prevent me accessing the file, rather than permit it and then treat the sectors as bad?

And I have no idea how. I noticed that iTunes deleted more then half of my photos off my ipod, but didnt think anything of it, and then i started yahoo messenger and it said it was corrupted and to run a chkdsk. So I did, and this is what it came up with (below). What caused this? All my photos are back, it said it was recovering orphaned files and stuff. But there was too many to count. [code]

a number of backup copies of large files on external USB-connected NTFS drives differed from the source versions still on my hard drive. I also discovered that I could reproduce the issue with newly-copied files.Here are the specifics of the issue, following a series of experiments:
- On my system, copies of large files, files typically larger than 500MB, are corrupted (altered) roughly 30% of the time when copying them under Windows 7 64-bit to USB-connected NTFS-formatted external drives.
- No error occurs / no error message appears during the copy
- The file size of copy is always identical, whether or not data was altered during the copy process.
- File differences are confirmed via either the command-line "FC" command or a utility such as WinDiff
- The issue impacts copies made via the Windows GUI -OR- via command-line copy or xcopy
- The issue occurs with multiple external USB NTFS-formatted drives, no matter what make or model.
- Subsequent attempts to copy an affected file will ultimately yield an identical copy. This would seem to rule out interference by an external program such as an anti-virus program (and the only AV I am running is Microsoft Security Essentials)
- The USB drives involved pass error checks, and copies made to these drives on other (non Windows 7) systems produce identical copies
- So far, the third party utility "TeraCopy" manages to consistently produce clean copies, and therefore is a temporary workaround. This utility apparently works because it, by default, bypasses the NTFS memory caching operation used by the Windows 7 OS...a caching system which I have so far found no way of disabling.
- The problem does not appear to impact relatively small files (1 to 100MB or so). I have not found any particular threshold, but I have seen the issue impact numerous files in the 500MB neighborhood.
- The problem seems to date at least to the version of Windows 7 that was in release as far back as the Fall of 2010, as I discovered corrupted backup copies of files dating back that far. Again, the files are corrupted with respect to the original copy...NOT with respect to file structure itself.

So I found a post on this forum with a similar problem. I'm trying to move a file that is larger than 4GB in size from my main hard drive to an external, and getting the error message in the title. The consensus on the other post was that the hard drive must have been a FAT format, and that too fix the problem either split up the file or reformat the hard drive as NTFS.Well, by all accounts, my computer is telling me that my external hard drive is ALREADY formatted as NTFS, but I'm still getting this error. I would prefer not to split up the file, but other than that, what are my options?

Any recommendations on Fast Drives that can save large files 8+ gigs in a matter of seconds. I have a USB 3.0 drive, even though it's connected to a 2.0 port, I'd still prefer something more faster, besides I want it to be internal.

Can't save large file to Windows & desktop. Keeps telling me I don't have room. Is there a setting in Windows 7 that restricts file size on the desktop?

He has a Windows 7 64bit OS with 4GB of ram. He has been downloading a set of 8GB files and almost like clockwork, his entire system starts chugging at about 3GB. He is NOT using a bitttorent. He is using a download accelerator and he has tried a different accelerator to eliminate the possibility that it was the software. He does have comcast, but he says that in the past, he's never had issues with traffic shaping. Also, his SYSTEM is slowing down (anything else he does gets really choppy) not just the download, so we think that indicates it's not just the normal ISP stupidity, it's something wrong on his system side.

Yes, I STILL need to burn to a regular CD as CDA is all that will play in my car. I have an audiobook in one large file & have tried breaking it down into several smaller files for burning. The first file burns just fine, but all subsequent files fail as it claims they're too long for the cd, even tho the size is a miniscule CDA. Older versions of windows used to prompt you for subsequent discs but I can't get any program (Roxio, Ashampoo, Cyberlink) to do so--they all return too large for disc.

I had to re-install Windows 7 on my computer as I had to replace the motherboard. I backed up my outlook.pst file (2.3 gb) to a DVD and after installing Office 2007, I copied the PST file to my desktop. Now when I try to import it or read it using Data Management, I get a message saying this is not a personal folder. I know there are tools out there that can manage larger pst files

I downloaded a 4GB .mkv file of a concert I wanted to watch. But since this was on my netbook, I tried to transfer the file to a 16GB Kingston USB Drive which is empty as I have bought it new. However I get an error saying that the "file is too large for the destination file system" and thus, cannot move my file to the USB. What is going wrong here?Here's a picture of the popup that occurs.

I am running Office 2010 on Windows 7 64-bit. I just created my first PowerPoint presentation containing 30 slides, all containing images, with a total of 35 images overall. All of the images together add up to less than 6 MB. During the creation of the slides I was careful to follow the guidelines for Sizing Digital Images For Powerpoint. However, when I save the presentation to disk, it is over 55 MB! I have tried to Compress Pictures from the Format toolbar-- no effect. In fact, file size of the presentation was larger after this. If I go to File>Info>Optimize Media Compatibility, this option is GRAYED OUT and does not work! I want to be able to send this presentation as an email attachment, but 55MB is way too big!

Just installed Windows 7 64 Home Pro from XP two days ago. The last remaining issue I need to solve is a drag and drop file transfer to my other home network computer (HNC).o far I've been able to d&d files from the HNC via Acronis WD in it's explorer mode without any issues, some sized in the multi Gb range. I'When I try to d&d a large file, specifically my NVIDIA drivers sized at 123Mb the Windows 7 computer freezes immediately. The cursor is stuck and the computer is absolutely locked, the only thing that works to recover it is the power off button.When I come back I don't get any indication of anything going wrong and if I look on the HNC drive the file has been transferred successfully
