Corrupt Backup Image

Hi everyone,

i backed up my hard disk with an unknown version of TI. It was installed on my last computer that is now formatted....

now i installed TI 11 8053 Registered version on my new computer and trying to restore some file.

the image is a full hd image spitted on 6 x 3.99GB file

everytime i try to select the backup image TI tells me that it cannot find volume 1.

i tried to backup and restore my current disk and it works correctly.

using an hex edito i notice that all new image files start with this hex sequence "B4 6E 68 44 2A 7B 1D EB" + 1 byte corresponding at archive number
ex:
backup1.tib = "B4 6E 68 44 2A 7B 1D EB 01"
backup1.tib = "B4 6E 68 44 2A 7B 1D EB 02"
backup1.tib = "B4 6E 68 44 2A 7B 1D EB 03"

doing the same test with the corrupted image i found the "magic sequence" only in the last file, the other 5 file start with random or pseudo random sequence...

is this correct?
is there a way to recover this (for me) important files?

any help is appreciated

ps : sorry for my bad english...

 

ops...

the 6th file old corrupted image start with "B4 6E 68 44 A7 E3 CE E2" + "06"

when in GUI i select this file it found the contents (index). but whe select the other 5 it don't...

any news?

 

Can you post the exact filenames and file sizes for each split?

 

hi,
thanks for suppor

the file names are:

backup1.tib 4.194.304KB
backup2.tib 4.194.304KB
backup3.tib 4.194.304KB
backup4.tib 4.194.304KB
backup5.tib 4.194.304KB
backup6.tib 441.386KB

i tried reinstalling version 10.0.4942 (the previous version) and it shows me the same error (insert volume 1)

any other suggestion?

 

Can you please post the file created/modified date & times for each file also (sorry, I forgot to ask in the previous post)? You can use a screenshot from My Computer if that's easier than typing it all in.

Were the splits created because the image was saved to a FAT32 partition or did you select a split value manually?

Also, it may help to see what the first nine hex values are for each file.

However, I suspect that the image was created with an early version of TI 9 or possibly TI 8 or 7. Do you have any of those versions to try with the backup?

 

the usb external drive i used for backup is a fat32 formatted disk...

the file created are:

20/12/2007 11.30 4.294.966.784 Backup2.tib
20/12/2007 11.35 4.294.966.784 Backup3.tib
20/12/2007 11.39 4.294.966.784 Backup4.tib
20/12/2007 11.47 4.294.966.784 Backup5.tib
20/12/2007 11.49 451.979.264 Backup6.tib
20/12/2007 11.25 4.294.966.784 Backup1.tib

I confirm you the version I use for this backup is 10.0.4942

the first 9 hex byte of the file are

backup1.tib 4D 5A 90 00 03 00 00 00 04 00 (it seem a PE Executable file but it doesn't)

backup2.tib 4D 5A 90 00 03 00 00 00 04 00 (same as above)

backup3.tib 3C 3F 78 6D 6C 20 76 65 72 73 (this seem an XML file... but later in the file bacame a binary file...)

backup4.tib 50 4B 03 04 14 00 08 00 08 00 (this seem a Zip file... like the above files it doesn't)

backup5.tib 50 4B 03 04 14 00 08 00 08 00 (see above file)

backup6.tib B4 6E 68 44 A7 E3 CE E2 06 00 (the corect header )

 

I assume that backup1.tib and backup2.tib have only identical headers and the complete files themselves are not identical. Have you run a check on this? (Same for backup4.tib and backup5.tib.) A visual check in the hex editor is usually good enough to tell if the files are different. From the times, they look like they were created in sequential order correctly.

I have checked the headers for image splits back to TI 9 build 3,677 (the earliest build I have) and it is still is B4 6E 68 44 .... ##.

Is it possible that these files somehow got corrupted by a chkdsk /f repair or bad hard drive?

When the image was created, was it validated/verified?

 

tha image file was not verified
no chkdsk was run on tha drive

any other help?

 

any1?
