Files Corrupted After Being Copied To A Different Hard Drive
Feb 11, 2012
I copied several large files (between 1 and 4 GB) from one USB hard drive to another. At the target destination several of the files had defects. They were in general not completely unreadable. Most could still could be opened but had clearly corrupted data. how can this be detected/prevented. Doesn�t Windows 7 have some kind of an integrity check when copying files? Also is there any good software to compare files for being exactly identical down to the last bit? Ideally with the capability to compare whole folder contents so that it hasn't to be done file by file.
At the moment, my Gateway M-Series laptop which has Windows 7 32bit will not do a system restore! It says my local disc ( C: ) has errors, it cannot check these errors so that I can restore the computer
My computer doesn't want to connect to the Internet also (lucky for me I have other means of accessing the Internet) and every time I open Chrome or any of my software it says there are corrupted files and the disk check will not run because there are corrupted program files? I haven't downloaded anything of late I keep a fairly clean hard drive, but when I went into system restore it set one of the restore points as 'DirectX Installed' which incidentally I haven't installed and isn't in any programs list.
After some tweaking I found I was able to check the disk and restore the computer but I would still like to know if any of you have any input on how to avoid future problems!!
I have a very important question about files I copied on to a different drive.I copied all my data(user account) from my C drive to my E drive. The E drive already had data on it before and has plenty of room.I saw that the data was copied then I did a "Windows Easy File Transfer" of the same C User data and also put it on the E drive. The windows easy transfer made one file.Then I reinstall Window 7 Pro on to C drive. I booted up the computer and looked in the E drive for my data, but Windows changed that drive to F from E. I looked in F and there were the files, but I could click on them. I rebooted the computer and upon boot-up the computer wanted to do and chdsk on F and I let it. Now I cannot see those files that I copied before the reinstall, but I can see the other files that were on that drive. Also the used space does not add up to what the drive says, so I think the files are there, just cannot see them.how I can get those files back.
make a dualboot comp by adding windows XP to a new partition. I created the new partition with 20gb. (From the 500 of my actual harddrive)But before I actually installed on that, I got distracted with a second harddrive that my dad got(for no reason). It had a full copy of Windows XP backed up on it from another computer, so I figured I would just use that for the dualboot. I plugged it in (wired the same way as my old harddrive, but different data slot), restarted, checked the harddrive in explorer - all the data was there / reading correctly / etc, and I used 'easyBCD' to add the new harddrive to the boot list.(Which, of course, crashes if I try to start it. I just wanted to see what it would do). For a reason I can't remember, I unplugged the second harddrive for a bit, started the computer on accident (I don't know if anything loaded before I shut it off), and then when I plugged it back in.Windows 7 would not launch. It goes to a DOS-like window, except it's just a flashing _ and it never does anything even after a few minutes. XP didn't work still.. so I decided to reinstall XP (as I couldn't tell which harddrive was which on the list, I unplugged the main harddrive while installing onto the new).. and when I did this.. it formatted and installed fully... then restarted.. then restarted.. and restarted.. and just kept restarting, never showing any thing past the manufacturer logo/BIOS load-button-message-thing. So, I then try to use my 3-disk Windows7Recovery disk(burned myself with a program apparently included by the manufacturer.) It installed fully, appearing to work.. but when I launched it, it said "Invalid Partition Table" and wouldn't boot past that. When I insert my driver installer disk, it gives me a basic DOS window thing. dir A: shows the files in the disk. dir B: for some reason shows the same. C: says "Error reading from drive C: DOS area: general failure". All other letter:'s just say "invalid drive". (I'm doing this with both harddrives in.) I attempted connecting the harddrives to an old computer, but it gave an error for both. (It detected the harddrives, but said it had an error reading from it. Windows Explorer asked me to format it... {i'm willing to format one of the drives if anybody thinks it will help, but the old harddrive has data I'd prefer not to lose.} ) Looking on google, I saw several problems that all have similar problems (less overdescripptive than I am though) but none of the fixes suggested worked for me. Also - as I have two different with different errors, I only need to make one of them work.)Also - my other available computer has a CD burner / floppy drive if either are required. I also have several USB's. The computer can boot from USB's and CD's (tested), and I could easily take the floppy thingy and connect it to the computer.also - this computer is probably still under warranty unless unscrewing the hard drive voids it. .. does that count as modification of the computer?
I recently installed Windows 7 x64. When I plugged in my external USB drive, it brought up the scan disk box and said I should check for errors. Ran it, and later I found some of my folders/files were corrupted. Tried a couple unerase utilities to get my critical info back, and failed. So, I ran scandisk again. Now almost all the files read as corrupted and it asks me to format the hard drive.
I got pop up in utorrent says a directory is corrupt, I start to run chkdsk on that drive. In this case in have drive letter E. I click on computer, then go to the drive, right click, properties, tools, check now. It says the drive is need to to forced to dismount. I click on ok. then in computers, the drive just show the letter, not size or disk meter. In the open windows on task bar, I did not see scan disk running, or maybe I accidentally closed because I was switching between several programs.
I thought restart pc the drive will show again, but after restart, the drive does not show up, it says 'E: is not accessible, the file or directory is corrupted and unreadable.' I tried to start pc 2 times, still same. I downloaded Partition Wizard Home Edition (minitool partition wizard home edition 5.2) and running it, it showing my files are still in the drive, but not accessible in windows. I also run chkdsk in recovery environment, but still says disk is corrupt, chkdsk cannot continue.
I've been using a flash drive for coursework and transferring data and windows 7 suddenly decided it was corrupted despite me finding no problems with it. So me being me decided to allow it to try and fix it and guess what happens, I wind up with a file with the same name as the folder it decided to remove and a new folder full of what looks like setting and configuration files (got a cog icon, cant remember what extension they have). How do I recover files that haven't been backed up???????
I have a virus infected sata hard drive with windows 7 on it. It has the win 7 anti virus 2012 on it, and it's a cybercriminal virus. I have lots of files I want to transfer to the new sata drive. I already have windows 7 installed on the new drive. How do I get the files from the bad drive to the new one?
I have a USB Webcam 6.1.7601.17514 from Microsoft installed on a Fujitsu Laptop (Windows 7 ) and I want to copy and install it on another Fujitsu laptop (Windows 7).The other laptop the camera is not working and there is no webcam driver installed.
I recently got a new iMac so am trying to copy/move some files around. However ANY file i copy onto the hard disk (which is in NTFS format) are not visible in Win7. The folder into which i copied into is visible but shows size as 0 bytes, whereas there is around 1.7TB of data in that folder. ALl older folders which were created/modified in Win7 earlier are visible. If i attach the disk to the Mac, the the files are there.. Am using Paragon NTFS if that matters...
I have windows 7 on my HP desktop and i needed windows xp for a certain program for school so i created a partition of 40 GB and formatted it as NTFS... I booted the installation disk and it was loading setup and it said the thier is no disk drive or partitions so i booted 7 back up and Googled it and it said something about raid drivers and SCSI or something needing to be updated... so i booted into setup and noticed that my SAta controler or waterva it is was set to raid so i set it to IDE and booted it this time after loading setup fles my partitions were there so i selected the 40 gb partition and pressed install it copied seup files for Windows xp and said rebooting... it rebooted and all i see is ( _ ) <-- that thing blinking forever so what do i do i've been googling it for ever and cant find what i want so either what do i do to fix it and install windows xp so it's working or just get rid of xp and it temporary copied install files
I'm trying to back up my "data" drive to an external hard drive. The properties on the disk show that there is 910 GB of data on the disk. But, when I select all files on the drive (hidden files/folders shown), it only adds up to 899 GB. Even worse, when I begin copying files, only 835 GB is found and begins to copy. What could be causing this/how can I copy ALL my data? Running Windows 7 Professional x64 Drive contains media files (lots of media files), software installers, .iso files, backups, and system images. Plus a lot of other stuff. Image of drive + file information: [URL] Edit: Tried taking ownership of all files and directories, and allowing my user full control.
I have recently been using some .bat tools to speed up searches in root directories.The tools search for the files in a list.txt, and copy them to a new folder which appears on my desktop. It has been working, until I used a new version today.It copied the files correctly, but I could not see the new folder appear on the desktop. I searched for it and found it where it should be, C:UsersEvanDesktopWhy does this folder exist, but not appear visually on my desktop? is it an error in my.bat file or something else
I have tried to copy a complete file heirarchy from one drive to a folder on another drive but found several files and folders are not being copied.
There is no report of files missed or any kind of error message.
I am actually trying to copy the contents of a friends hard drive onto a backup drive since he is getting a new computer and wants to ensure nothing is lost. I have mounted his internal 2.5 sata drive in a caddy and am copying it to my computers second internal drive.
I expected not be be able to copy certain system files. I also expected I might not to be able to copy some of his personal files due to the standard windows system protection (I am system administrator on my PC whereas of course he was administrator on his PC where the files and folders were created which I thought might be an issue). When I first tried to view some folders I was asked by the system if I wanted to allow permanent administrator priviliges to them (namely his personal directory under "Users" ). I replied yes and was thereafter allowed to descend into and view those files. Now when I copy the entire heirarchy of some 35GB I find the new folder is only 15GB. It is not just down to any compression as I have confirmed that there is only about 1/3 of the expected number of files to what was in the original. I have since tried individually copying some of the sub-folders that were missed and they copy fine on their own. As you can imagine, trying to dentify what has copied and what has not is a mammoth undertaking.
I have a new computer with Windows 7 on it - and I want to copy the files from my old computer to my new one. I'm looking at copying about 300 GB worth of data.When I copy all files and insert them onto my new desktop, I notice that all of the date/time stamps are changed to today's date.Is there a way to preserve the date/time stamp for each file, so that it keeps the original one?
I was lucky to grab a recent image backup from a failing 1.5 TB drive. Can I restore it to a smaller drive if the available space on the original drive was well below 1TB?This is the first time ive had to work with this particular image file. I have restored from backups before, just not this type of image.
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.
My setup: Windows 7 Pro (locale: Polish) and a NAS drive (D-Link DNS-323) attached via a router. Just recently upgraded from XP to 7. The NAS drive reports an NTFS partition.The problem I've just discovered: when copying files to the NAS drive, if a filename contains certain characters, such as curly quotes, angle quotes, bullet characters, subscript characters, em-dash etc., only the short 8.3 filename gets copied to the NAS drive.(I would not sweat it if the troublesome characters just got dropped, but what happens is that meaningful filenames are replaced with gibberish as above.)I use the NAS drive as a backup/mirror location for the local drives, so this is a big issue, since my backups are now severely clobbered. I discovered the problem while testing my backup regime, then found out the filename change occurs no matter how the files are copied - whether it's the backup application, a file manager or just Windows Explorer.And (of course) the problem did not occur when I was running XP, and nothing on the NAS drive changed since I installed 7 a week ago. Files that were previously copied onto the NAS drive (under XP) still show up fine, which tells me that 7 is actively interfering with the copy operations.
my wife broke our laptop, i had all of my music on that hard drive and hadnt yet backed it up. the hard drive is still good, so i bought an external hard drive enclosure and put the old hard drive in it. i hooked it up, but am not able to get to any of my files off of it. computer recognizes it is there, shows folders, but wont/cant read files. wont open itunes or any other programs i had on it.the old drive was in windows vista, new computer is windows 7. does that matter?what do i need to do?
I am using Windows 7 OS. I had two logical partitions, E & F. I saw an unallocated free space on my disk. I tried to to mount unallocated drive to another
logical drive , it asked for the folder,where I wanted to mount I gave one folder in E drive. it asked if i want to format...i said
no. and thats all,process completed! And just then I saw there was no other logical drive left...neither E nor F. Now I can see only C drive and nothing else. how to recover my hard drive and the files now?
I am a salesman in a tech department of an office supply store, and I had a customer issue stump me today. She had an external drive with lots of files on it she wanted to access. I took the drive, plugged it into a Windows 7 machine (HP quad), and all of the files appeared, no problem. But, then I plugged the seagate drive into her new Toshiba laptop (also Win 7), and only some of the files appeared. Missing were all photo files, and many other types. I could not figure out why some were missing and some showing. I took the drive to a third computer with Win 7, an MSI all-in-one, and behold: files were missing. Now it seemed almost arbitrary. Could it be a matter of some Windows updates not yet installed? Why would the exact same drive work differently on three different computers in regard which files were seen and accessible? None were "hidden" files.
I just bought a new computer, i7 860 and have put 7 x64 on it.
my motherboard is ausus p7p55d and has one ide socket on the board.
I was using this socket for my cd and dvd drives but I have detached them so I can plug in my old IDE hard drive.
I was using the IDE drive just 2 days ago in my old system.
Sometimes when I boot up the drive is seen and sometimes not.
when the drive is seen I try and copy some files over to my new sata drive I have in the new system. some of the files copy over but the the IDE drive always gets stuck. when I try to cancel the copy windows stops responding partially and I cant get out of the copy window and the old IDE hard drive explorer window.
So I restart windows and normally it now doesn't see the IDE drive.
I can see a generic storage device listed under the universal serial bus controllers in the device manager and am able to see the 'safely remove hardware' icon in my tray. Unfortunately, the only thing that I see in disk management is an 'unknown' disk. The hard drive is listed by manufacturer in the device manager; however, I am not able to open it from this site. And, when I look at the items 'attached' to my computer, the drive is not visible.
its been a long time since i last posted about my bsod and after i fixed them i began to get more of these. the only way i can replicate the problem is when i move or copy+paste files in the computer, mostly if it is from my computer to a external hardrive or usb... i attached the latest minidump file i got 021412-15958-01.zip
Edit: Go another bsod... if it helps i uploaded the minidump from that crash 021512-21153-01.zip
I've had this laptop for a few months now and I got another hard drive called Data which is empty, my other hard drive called OS is where everything goes and I wondered if I can move games and other files to my Data hard drive without corrupting them. And if possible can I move a file called Program Files to my Data hard drive without causing any problems. My pc takes a long time to restart which I guess my OS decides. My OS got is 80gb of 238GB and my Data is 332gb big, with no files in it.
