Need Data Recovery software for failing HDD

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 |

Is there a Windows version of ddrescue?
It sounds like you aren't familiar with the long filename suite of executables that give plain old 8.3 dos mode the full power of long filenames for use in say copy and make directory operations?
DOSbox under Windows will do long filenames but they must be quoted and it's likely that full support isn't really there - it's an emulator after all and not really DOS. And as such it would be using the Windows driver to access the hard drive in the first place. And we already know it's blind. http://lfntools.sourceforge.net/ I would have never let scandisk run myself, pulling the plug much more preferable to having that thing autocorrect something I have no control over, nor can I get the fix put back and it's all built into scandisk automagically. You can try to have it set up so that it doesn't, but it always does just what it wants anyway. |
