3 TB Data HD: harddisk seems too small

#1 Post by DiskTest » 24 May 2017, 05:24

Hello,

OS: Win10x64 (Just upgraded from Win7x64 when the problem started)
Disk:
Type Fixed Disk, Data disk (Not bootable)
System Name 81h
Partition Style GPT
Total Size 2.73 TB (3 TB)

The disk was working fine in Win7x64 desktop as a data disk, but when I upgraded the system to Win10x64, the disk really slowed down, and then and failed showing up as RAW.

During the run, TestDisk gives errors like "check_FAT: Bad jump in FAT partition" and then towards the end, the following:

Check the harddisk size: HD jumper settings, BIOS detection...
The harddisk (801 GB / 746 GiB) seems too small! (< 3000 GB / 2794 GiB)
The following partitions can't be recovered:
MS Data 2048 4294965247 4294963200
NTFS, blocksize=4096, 2199 GB / 2047 GiB
MS Data 264192 5860532223 5860268032 [Movie Backups]
NTFS, blocksize=4096, 3000 GB / 2794 GiB


The partition "Movie Backups" is the only partition, and it has over 2TB of data. I started running Deep Scan. What shoud be the next steps? Thanks for your help.

The partition table is ok, your partition is listed, so there is no need to try to undelete it.
Run TestDisk, Advanced, select the partition "Movie Backups", Boot, RebuildBS, List.
If you can see your files, choose Write, confirm, Quit and restart your computer.

Thanks!

I ran TestDisk, Advanced, select the partition "Movie Backups", Boot, RebuildBS, List.
I can see your files, but there is no Write option. How do I proceed from there?

(BTW, after RebuildBS, it says the sectors are identical, if that matters).

Thanks again for your help!

PS: If I go to Analyze screen, I see duplicate partition #1.

Re: 3 TB Data HD: harddisk seems too small

#4 Post by DiskTest » 27 May 2017, 20:25

Something else is interesting: I used ddrescue to copy the complete disk to a new disk. When I see the old and the new disk in the disk details screen, I see that the data partition size in both of them is just 746GB, while in reality the partition has over 2 TB of data. (The size of the overall disk is listed correctly).

When I list the files in TestDisk, I am checking just the first top level directory listing. Is it recommended that I go through the complete hierarchy to see if any files are missing? And if I do find that some files are missing, what do I do to recover everything?

Finally, I see an option to select all files and copy to a different location. can I simply select all files, and copy everything to a new drive? Are the files copied just as they were, or are they copied in some kind of image format that requires mounting using a different tool?

Thanks.
