More information is needed from you. Is it the same file that is missing each time? If yes, what is the name of the file? Do you mean SATA optical drives (CD or DVD drives)? If hard drives, what sizes are the SATA hard drives?

it is not the same file eash time but ther is one missed more than one time named c_720.nls its location C:\WINNT\system32 it is a sata hears drive 80 GB mono hkamel

There are free language translators on the internet. If English is not your native language, if you tell me which language you use, I may be able to tell you which one(s) you can use to translate the following to your own language. If you find the following too difficult to understand, I need to know - are you trying to install Windows on the SATA drive? - is your problem you cannot get an existing Windows installation, or Windows Setup, to recognize the SATA hard drive? - if Windows is already on a hard drive on these computers, what version of Internet Explorer is on them? - exactly which files are supposed to be missing, and what exact error messages are you getting? ....... Is your problem you cannot get an existing Windows installation, or Windows Setup, to recognize the SATA hard drive? If Yes, see SATA DRIVERS at the end of this. ...... I searched the web using: c_720.nls I found absolutely NO EVIDENCE the error loading this file has anything to do with you having a SATA drive!!! c_720.nls is apparently a file used by Microsoft Internet Explorer. There are various versions of it in various versions of IE. I found it is in as early as 4.x versions of IE, right up to it being in the IE in Vista. If you are using the IE version that came with Windows, this file (the compressed version of it, c_720.nl_ ) is on your Windows CD - the version is whatever version was included with your Internet Explorer version. If you have installed a newer version of IE than the one on the CD, there may be a newer version of this file included with the original installation download or the installation done on the web via the Microsoft site. Whether you have it on your hard drive or not appears to depend directly on which language you are using for Windows. e.g. if you load Arabic language support, apparently it is supposed to be installed. found here: http://www.911cd.net/forums/index.p... "; Arabic.inf ; PE Builder v3 plug-in INF file for Arabic Langauge [Version] Signature= "$Windows NT$" [PEBuilder] Name="Arabic Langauge" Enable=1 [SourceDisksFiles] KBDA1.DLL=2 kbda2.dll=2 c_720.nls=2 c_708.nls=2 c_864.nls=2 c_1256.nls=2 c_10004.nls=2 C_28596.NLS=2 c_20420.nls=2 " - my language is English (CANADA), and I do not have support for other languages installed. I do not have c_720.nls on my XP SP2 installation, but I have lots of c_*.nls files in C:\Windows\System32 (* stands for "wildcard" = "anything" when you search - in this case, if you search using c_*.nls it finds any file that begins with c_ and ends with .nls) - my Windows 98SE installation does not have any c_*.nls files - it does, however, have lots of other *.nls files - so I assume c_720.nls is, and c_*.nls files are, only on Win 2000 CDs (and possibly NT CDs) and newer, or in versions of IE when you install it for Win 2000 (and possibly NT) or newer. You DO have c_*.nls files on your hard drive if it has already been installed - you may or may not have c_720.nls. Try searching for it. On my XP SP2 computer (with SP3 updates later installed by Windows Update) all the c_*.nls files are in C:\Windows\System32, as well as there being other *.nls files there - there are a few *.nls files in C:\Windows\ServicePackFiles\I386 but none begin with c_. Generically, they are in %System32%. In XP that's usually in C:\Windows\System32 In 2000, that's probably in C:\WinNT\System32 In posts I fould on the web, - in XP, if you have it here C:\Windows\System32\c_720.nls you should also have it here C:\Windows\System32\dllcache\c_720.nls In your case, if you have it here C:\WinNT\System32\c_720.nls you should also have it here C:\WinNT\System32\dllcache\c_720.nls If you have C:\WinNT\System32\dllcache\c_720.nls but not C:\WinNT\System32\C-720.nls copy c_720.nls from C:\WinNT\System32\dllcache\ to C:\WinNT\System32. - for XP, the Windows CD has the original version of c_720.nl_ (the compressed version of c_720.nls) in the \I386 folder on the CD. It should be in the same place on your 2000 CD ..... If you don't have c_720.nls on your existing Windows installation at all, - if the version of IE you are using is newer than the version included on your original CD, you will probably have to install that version of IE again, and specify the language you want to use when you are installing it. If there are language specific versions of the IE version you want to install, install that, rather than using the English version - in that case the English version may not have c_720.nls included with it. - if, and maybe ONLY if, the c_720.nls wanted is version that is for the version of IE included on the original CD ... (I don't know for sure, but I suspect the *.nls files on the CD may not be acceptable to Windows if a newer version of IE has been installed. You could try the following in any case, but Windows may find it's the wrong version) Insert you Windows CD in a CD drive. Note which drive letter the CD drive the Windows CD is in is using. A. If you are able to boot into Windows... Start - Run - type: cmd, click on OK type this on one line: expand (drive letter CD is in):\I386\c_720.nl_ c:\WinNT\System32\c_720.nls (press Enter) e.g. my CD drive letter is K - yours is probably different I would type: expand K:\I386\c_720.nl_ C:\WinNT\System32\c_720.nls (press Enter) note the space after expand, and c_720.nl_ - expand uncompresses the file - c_720.nl_ is the name of the compressed file on the Windows CD. If a file on the Windows CD is compressed it always has a _ as the last character instead of a letter or number. - c_720.nls is the name of the expanded - uncompressed, full size - file - in this case the file is supposed to be in C:\WinNT\System32 B. If Windows will not load because it can't find the file, you need to use the Recovery Console to do the same thing.... Boot the computer with the 2000 CD. After the initial Setup files have loaded from the CD, you are asked if you want to Repair Windows. Answer yes to that (in my case, in English, you press R) to go to the black screen interface that us called the Recovery Console. It will search for Windows installations and list them. Type the number for one it finds - e.g. if there is only one, type: 1 , then press Enter. You will see a prompt Password: - if there are no * characters beside it, there is no password - just press Enter - if there ARE * characters beside it, the password is the same one used for Administrator in 2000, then press Enter type this on one line: expand (drive letter CD is in):\I386\c_720.nl_ c:\WinNT\System32\c_720.nls (press Enter) e.g. my CD drive letter is K - yours is probably different I would type: expand K:\I386\c_720.nl_ C:\WinNT\System32\c_720.nls (press Enter) note the space after expand, and c_720.nl_ type: exit (press Enter) to get out oif the Recovery Console and automatically boot the computer. C.If that was the only file needed, Windows should boot normally. If you need more files, you can do the procedure in A or B for the other files ................................. SATA DRIVERS If your problem is you can't get Windows to load on the SATA hard drive drive at all because Windows or Windows Setup can't see it..... Your motherboard bios has the SATA drive controllers in the bios Setup in SATA (or AHCI, or similar) or RAID (or SATA RAID, or AHCI RAID, or similar) mode. In that case, Windows Setup cannot see your SATA hard drive because it has no drivers for the SATA controllers on the motherboard built into the contents of the CD. If Windows has already been installed on another IDE drive, it can't see the SATA drive because the SATA controller drivers have not been loaded in Windows. If you try to load drivers for the SATA controllers during Windows Setup from anything but a floppy disk in a directly connected to the mboard floppy drive, you will get an error similar to the following and Setup will quit. E.g. This is a message I found on the web a guy got when he tried to load the SATA drivers during Setup from a USB flash drive: "File \$WIN_NT$.~BT\$OEM$\WinXP\UlSata.sys could not be loaded. The error code is 14. Setup cannot continue. Press any key to exit." - the line you would see would probably be different, but note the xxSATA.sys file at the end - You must either... - set the bios Setup to have the SATA controllers in IDE compatible mode, or similar. In that case you don't need SATA controller drivers and Windows Setup will work fine. If Windows is already installed on an IDE drive, it will also then be able to see the SATA drive. - or - this is the ONLY default choice if you want to install Windows on, and boot Windows from, the SATA drive, and have the bios Setup have the SATA controllers in SATA or RAID mode while running Setup - ...you must boot using the Windows CD, press F6 near the beginning of Setup when you are prompted to do that to install third party SCSI drivers, then insert a floppy disk with the proper SATA drivers on it in a floppy drive when Setup later asks for the SCSI drivers. Setup will not accept anything but drivers on a floppy disk at that point in Setup. Usually that requires you have to have a regular floppy drive connected to a regular floppy header on the mboard. Very few USB connected floppy drive models are recognized by Setup at that point, most models are no longer being made, and it will not try reading from a CD or a flash drive or a hard drive at that point. If you don't have a regular floppy drive and cannot borrow one, and/or if you don't have a floppy header on the motherboard, you have to make a bootable slipstreamed CD that includes the contents of the Windows CD with the SATA drivers integrated into it (you can also integrate SPx updates into it) , if you have the bios Setup have the SATA controllers in SATA or RAID mode while running Setup ...... If Windows has already been installed on another IDE drive, if you install the drivers for the SATA controllers, Windows will then be able to see the SATA drive when the bios Setup has the SATA controllers in SATA or RAID modes. If you don't want to install Windows on, and boot Windows from, the SATA drive, that will work fine.
