How do I identify where files are located and where they start and end? Even if I locate a file, how do I associate it with a file name? | ||

This can currently only be determined automatically on FAT16 and FAT32 drives. On floppy disks, you would have to browse the FAT12 directory entries yourself, e.g. using the appropriate template. Start at the root directory. | ||

Just logged on and have read a couple of messages on disk editing and data recovery, both informative. I think this will prove to be a valuable forum. Thank you. | ||

Concerning the original posting, on locating a file on a floppy disk: You may also search for the file's short DOS name (without the dot!) on the disk. This will lead you to the directory entry of the file. Use the appropriate template on that entry to find out the number of the first cluster allocated to the file. Finding that cluster and possibly additional clusters (depending on the file's size) requires some knowledge of the FAT file system (see here). It might be easier to directly search the floppy disk for known file contents. | ||

Stefan, I recently purchased WinHex v 9.72. I am having trouble 'Disk Editing' a 3 1/2 floppy disk. Under the 'Physical Disk' option I get Error # 6, "An error occurred while reading from Floppy dish 1". Then the prompt "Retry reading the sectors?" After selecting 'Yes' it circles back to the 'Error #6" message. Any suggestions? I am trying to edit a DOS program that I purchased legally many years ago and that has stopped working. I am long out of the 1 year support they provide. I think the copy protection scheme has tripped and it tells me to call customer support (and makes the program inoperable). Thanks, John Bloom | ||

Hi John, I'm afraid that protection scheme works with deliberately damaged sectors and WinHex is not able to work around that. You can also try logical disk access (under Windows 9x), but sorry, I cannot raise high hopes. WinHex is not designed to access physically damaged sectors. Stefan | ||

I am having the same problem as John Bloom. I have just downloaded a copy of 9.72 for eval and have attempted to read several diskettes, all that are known to be good. I am getting the same errors that he reports. I am using Windows 2000 Pro Service Pack 1 on a Dell Workstation 220. I have the same results on a Dell Laptop. By disabling the caching I have been able to successfully read a few sectors. I was hoping this would replace an old program that I had from Norton years ago called disk editor. I need to change the pointers at the end of each sector of files to reconstruct an overwritten file with the same file name. I believe that if I can get to the raw data, I can manipulate the last bytes of each sector and move the end of file flag. | ||

I will prepare a fix for this and send it to both of you, probably still today. | ||

Now can I change a floppy drive's serial number (like 19F6-191D)? I was trying to find this hex number, but couldn't. Thank you | ||
| Stefan Fleischmann (Admin) |
You will find it at offset 0x27. It may be stored in reverse order (compared with what you expect). You can also edit it using the template "Boot Sector FAT". | ||

How can I mark a 1.44 floppy disk sector as damaged? | ||
| Stefan Fleischmann (Admin) |
Please refer to the Knowledge Base for detailed information. You can mark a cluster as damaged by setting its 12-bit FAT entry to 0xFF7. On a floppy disk, one cluster consists of exactly one sector. | ||

Concerning the original posting, on locating a file on a floppy disk: FAT12 is fully supported since WinHex 9.8, so you may use Tools | Disk Tools | List File Clusters. | ||

I just got a licence but I`m not a computer literate pls. some help. I need to create a Keydisk Were to enter the info Example I have to change first 5 bytes of sector 1... How? Thanks | ||
| Stefan Fleischmann (Admin) |
I do not know what a key disk is, but to change the first 5 bytes of sector 1, you proceed like this: 1) Tools | Disk Editor. Select the disk. Click OK. 2) Position | Go To Sector. Enter 1. Click OK. 3) The cursor is now on the first byte of sector 1. Change the first 5 bytes now. 4) File | Save Sectors. This assumes you really mean sector #1. Sector #1 actually is the second sector, since the first sector has the number #0. | ||

I created a text file in Notepad and then saved the file to a floppy. I then used WinHex to locate and edit some of the ascii codes in the file. When I close down WinHex and then restart and load the text file, the changes made are still there, as I would expect. However, when I open the text file again in Notepad, the original file contents are displayed, not showing any changes whatsoever... Please advise. | ||
| Stefan Fleischmann (Admin) |
Maybe the original file is still in some kind of cache? Does it help to restart Windows? | ||

I run a computer lab and I have Windows XP Pro on all the computers. I am having a problem with the floppy disk. People come up to me and tell me that they put their disk inside and it them to Format the disk, but they have data on it so how do i get it back. | ||

Hi, I have a dos based program that's read any string from 1.44 floppy. This floppy i have to inserted when i switch on pc. When we use this flopy for copy file that seems to be unusable. I want to copy this floppy for safty storage. What I have to do? plz tell me. | ||
| Stefan Fleischmann (Admin) |
You could use WinHex to copy data off the floppy disk, e.g. using Copy & Paste. You would open the floppy disk with Tools | Disk Editor. |
