All it needs to do is post a notice at the end saying file**** was not copied. Once I had a saved website, and the default filename of that website exceeded the long filename size limit. Every time I tried to copy files, it would stop at that file. Talk about annoying. It took hours to figure out which file was the faulty one. Then it would not allow me to rename it. I finally deleted it using Dos. Lesson learned, I always check filenames when saving a website now. Some are insanely long. I manually trim them before saving them now. dont happen, except to try to copy the WINDOWS folder. I can copy my Win98 folders though, when I am booted to W2000. I do however delete the Swap file before copying. I have done this for decades and it always worked fine. The important data I am missing is mostly electronic schematics and manuals. Some are near impossible to replace. I dont need a newer OS to use that stuff, (All that you've acquired since the last backup?) Yes, last backup was May 2017. I have about 20% of it on that backup.

I've had XP fail numerous times, and the HDDs cant just be plugged into another computer, and expect XP to run. Win98 can be transferred to That's why I image it (my main system is XP). I use Macrium 5, which I boot from a mini-CD. (It has drivers for external [USB - well, it can do network too, though I've not tried that] drives, and works fine with my 1 TB one.) The process, as you'd expect, takes no longer than a copy would. another computer quite easily, with only a few drivers added. I've also felt safer using FAT, versus NTFS, because FAT can always be accessed from DOS. However, in this case, that is not helping. I too feel that way about FAT versus NTFS. (However, apart from a disc dying, I've not had XP crash for years, and that may have _something_ to do with it being on NTFS.) Either way, I plan to install a 3rd HDD, now that I know I can. I may (You could even add it without removing the CD, by making one master and one slave, though if as I think you've said the CD is faulty, you might as well remove it at the same time.) That CD drive was unplugged years ago. I didn't remove the dead drive, just unplugged the data and power cables. But the cable is still in the computer, doing nothing. first have to go on ebay and order a few drives, although I think I may have a working 80gb drive in my spare parts. I know I have a few 40gb or smaller, but to copy that entire partition, I need no smaller than 50gb. I just ordered a brand new 120gb to replace this failing one. It was not I didn't know you could still get new EIDE drives! Are you sure it's new? Either way, might still be worth checking its SMART readout (using a USB-EIDE cable-and-power-supply from your XP computer) before committing to it. Yes it's new. Ebay has everything..... The 120gb is new, but I also bought a 160gb used one. It was so cheap I could not pass it up, and guaranteed to work. I figure I can plug that one on one of my XP machines and try to duplicate this defective one, before I mess with it. expensive, so I may just order another one, or an 80 or something like that. Thanks for the help from all who have helped. Do tell us how you get on! |

Is there a Windows version of ddrescue?
After being told about this program to assist in doing the cloning and
data recovery of my failed HDD, I did some looking up ddrescue. All I am seeing is the Linux version, and worse yet, it requires doing it by the command line. To me, this means I may as well just toss my failed drive in the garbage and say goodbye to my data. I have never had any luck with anything Linux, and if it involves the Linux command line, it's time to "hang up the phone". On top of that, it appears that to even run this thing means it needs to be burned to a DVD. That means I will first have to buy a DVD burner, and blank media. NO THANKS!!!! (That DVD burner would proably never be used again). I cant believe there is not something similar that runs in Windows, or even from Dos, which is just as good. I prefer to stay away from Linux as far as possible. I will run anything that works on Win9x or WinXP, or even DOS. (I am not afraid to use Dos command lines, because I was raised on Dos). So, what else is there? I'll even purchase commercial software if it's not over $50. But what do I use? I just cant believe there is nothing that runs on Windows or Dos, and think it's sort of ridiculous to have to use Linux to fix a Windows drive. --- One other thing, according to Norton Disk Doctor (for Win9x), the FAT table is defective. There is supposed to be a second copy of the FAT table, How can I swap to the second copy, and is it possible to swap back if that dont work? Yes, I know this dont apply to Windows 7, but I am sure all of this info would work for 7 as well.... I just use Win98 by personal choice and also have XP available. |

Yes, I know this dont apply to Windows 7, but I am sure all of this info would work for 7 as well.... I just use Win98 by personal choice and also have XP available. I didn't know about the first answer here, until happening on it. I've never had a disk fall into the gray zone, to test all these utilities and spot this. When I have a (really) bad disk, it dies before I can get any data off. https://www.data-medics.com/forum/ho...scue-t133.html "Why you can't clone in Windows: There are a great number of Windows based data recovery and backup programs out there which make claims of being able to clone hard drives with bad sectors. This may be partly true, as some employ bad sector skipping code to jump ahead a large number of sectors when a bad sector is hit and attempt to continue. However none are well suited to the task simply because all Windows based applications rely on the Windows host controller to interface with the drive. Currently there is no known workaround for this in Windows. The Windows host controller unfortunately does not allow software running in Windows to directly control ATA commands issued to the drive (such as read timeouts) which are necessary to effectively clone as much data as possible from hard drive with bad sectors. Fortunately there is another OS capable of running on your computer that does not suffer from these same constraints...." AFAIK, the disk drive itself can hold up the process for 15 seconds per sector, unless you have a drive with TLER in which case the time constant can be reduced to the 5 to 7 second range. The disk drive will try a *ton* of times itself, to read a bad sector. ******* http://www.cgsecurity.org/wiki/Advanced_FAT_Repair "Repair FAT tables File Allocation Tables are maps of the data region, indicating which clusters are used by files and directories. To repair the FAT, the menu Repair FAT will have TestDisk compare the two FAT copies. If the FATs mismatch (sector by sector check) or contains errors, *TestDisk* uses the FAT copy with less errors and removes the obvious errors. This function must only be used on FAT filesystems with correct values in the boot sector. It has been used with success when scandisk, chkdsk or fsck.vfat crashed or refused to repair the filesystem. " TestDisk 7 is available from that site, and runs in Windows. For example, on partitions with the "hidden" attribute, ones without drive letters like System Reserved, you can use the "file listing" interface, to actually list the contents of a hidden partition. The interface is a bitch :-) Press "control-c" to quit at any time. You'll eventually learn how to use it... somehow... TestDisk is also on the Linux DVD. ******* If you have a USB stick, one big enough to hold a 1.6GB Linux ISO file, the recent distros are UEFI hybrids with direct dd transfer capability. You can prepare a USB stick, just by downloading a Linux distro and transferring it to the USB stick, sector by sector. http://www.chrysocome.net/dd # This assumes the second drive seen in Windows is the USB stick. # Harddisk0 is the first disk. Harddisk1 is the second disk etc. # The block size should divide evenly into the size of the ISO. # The ISOs were properly padded to 1MB (1048576) byte multiples, # but newer ones are only guaranteed to be a multiple of the optical # disk sector size of 2048 bytes. I use "factor.exe" to factor the # size number and work out an optimal block size. dd if=c:\temp\linux.iso of=\\?\Device\Harddisk1\Partition0 bs=2048 That's to illustrate you *can* prepare Linux boot materials from Windows. No CD needed (except on year 2005 computers or older, that don't boot from USB). http://www.chrysocome.net/downloads/dd-0.6beta3.zip There are other tools for preparing boot USBs. ******* For certain classes of disk problems, you have to drop to *real DOS*. Count your lucky stars that Linux, with GUI convenience, exists for at least some of the problems you might encounter as an amateur data recovery specialist. One of my problems is, getting my DOS floppy to boot on modern computers. It's almost impossible (can't figure out how to modify memory map to make it fully functional). It took a lot of trials on my Asrock 4Core to make that work, but I eventually stumbled on the correct values. I haven't been as lucky on newer kit. HTH, Paul |
