Not sure how to proceed

#1 Post by junga » 29 Jul 2015, 15:52

Hello,

I would like to have a much needed help if possible, I run test disk analysis and it showed a space conflict, at this point I am not exactly sure how to proceed to hopefully recuperate the family pictures. :cry:
windows indicates that the drive is not accessible, the parameter is incorrect.
Things I tried: changing the drive letter, try to boot from a linux live OS hoping to see the files, but unfortunately without success.

Thank you for reading.

Can you repeat your diagnose and selecting disk instead of a drive.
Disk looks like:
Hard disk list
Disk /dev/sda - 1000 GB / 931 GiB - CHS 121601 255 63, sector size=512
Disk /dev/sdb - 1000 GB / 931 GiB - CHS 121601 255 63, sector size=512
Disk /dev/sdc - 3000 GB / 2794 GiB - CHS 45600 255 63, sector size=4096
Disk \\.\PhysicalDrive2 - 3000 GB / 2794 GiB - CHS 45600 255 63, sector size=4096
Drive C: - 981 GB / 913 GiB - CHS 119300 255 63, sector size=512
Drive E: - 320 GB / 298 GiB - CHS 38913 255 63, sector size=512
Drive F: - 3000 GB / 2794 GiB - CHS 45598 255 63, sector size=4096
TestDisk 7.1WIP 32bit is recommended.

You already have a partition in your partition table.
If this partition would be correct, you can have a try to run a boot sector diagnose.
Can you run testdisk, Advanced and Boot and upload another snapshot?
Can you use the menu List and have a try to list your files?
Until yet, don't use Write nor RepairMFT!
It's intended to avoid any changes to your file system.

Can you try to run on your current partition a RebuildBS and if the boot sector is different, you can have another try to list your files, using the menu List.
If it wouldn't help:
Can you run TestDisk Deeper Search?
The intention is, to find another partition by the backup of the boot sector.

Thank you Fiona,

RebuildBS:

Boot sectors identical could not list:

I could not see the back up of the boot sector.

Your current message displays only not recoverable partitions which end after disk limit.
Fat12 and FAT16 partitions are probably wrong.
At this display, when you press enter, you'll get to the results.
Did testdisk find another partition?
If not, you'll probably need datarecovery software which reads underlying data.
Can you copy and paste the content of your testdisk.log into your next post?
PhotoRec could help.
Info will follow.
