Seagate Backup Plus 4TB - NEED HELP PLS!!

[jmw637]

this external hard drive was almost filled up (100 GB or so free) so the other day i deleted a bunch of files to free up more space (now 170 or so free). i did so on a different computer than the one the drive is usually attached to, and when i reconnected the drive to that computer it still showed about 100 GB free (as if i hadn't done anything). i reconnected the drive to the first computer to make sure there weren't files waiting to be deleted, etc...but i couldn't resolve this descrepancy.

so i ran chkdsk on the drive which showed there were errors in need of fixing. but when i ran chkdsk /f i received an error to the effect that there wasn't enough room on the drive [for something...i can't recall exactly what!]. and the net effect of this was that it turned my disk RAW. it appears in computer management, but i have no access to any files (fyi, it should be NTFS with a single partition).

i ran testdisk, which found the following options (see attached testdisk screenshots - 1).

regardless of which 4000 GB option i select (and i've tried them all), i end up with this after partition is analyzed (see attached testdisk screenshots - 3):

after running both quick search and deeper search all i get is a message that "the hard disk seems too small!" (i didn't make screenshots of the specific results...which i can do, but it will take time as running the searches takes hours with a drive this large).

my question is, do you see anything from what is presented here that would help explain why i'm having trouble seeing my data (so i can write a new partition)?

your help would be greatly appreciated. thanks in advance...jeff

two other pieces of information (which may or may not be helpful):

1. if i select "drive e" (the same as in the attached screenshot above), but select "none" as the partition table type, i see what i'd expect...a single primary ntfs partition (labeled MEDIA). and both the qick and deep searches return a result of the same (highlighted in green) along with the message "Structure: Ok."

however, when i try to list the files, all i get is an error message ("Can't open filesystem. Filesystem seems damaged.") ugh....


2. when i run a chkdsk on the drive now, i receive the following error: Detected error in the Master File Table (MFT) mirror. Insufficient disk space to repair master file table (MFT) mirror."

i feel like success is at my fingertips...if i only knew what the hell i was doing!! so if anyone can point me in the right direction, i'd really appreciate it.

Compression is not the problem.

Would it be possible to select your disk instead of a drive?
A drive has no partition table.

i've tried selecting both 4000 GB disks (/dev/sdd & \\.\PhysicalDrive3). ultimately, i still end up with that same error message ("Can't open filesystem. Filesystem seems damaged.") when i try to look at the files.

[jmw637]

is the problem here that you don't have enough information to help me, or that i'm beyond help?

what do the results of screenshot 3 mean? is there something i ca do to make this work?

To select your disk (Disk / dev / sdd - 4000 GB) is appreciated, because I'd get information about your current partition table.
It has nothing to do if your file system is damaged.
At least I'd be able to check your partition table and your partition also.
If there would be any change or modification it could lead exactly to the same symptoms.
