Newbie - Please help, my data partition is raw :-)

#1 Post by Softwoolf »

Dear All,

I need help - I have an adaptec raid controller with different arrays on it, all except one running fine. The problem is one faulty drive on one of the arrays, which happened suddenly - the drive is suddenly listed as "raw" in windows 10 and cannot be accessed.

Here we go:

TestDisk 7.1, Data Recovery Utility, July 2019
Christophe GRENIER <grenier@cgsecurity.org>
https://www.cgsecurity.org TestDisk is free software, and
comes with ABSOLUTELY NO WARRANTY. Select a media (use Arrow keys, then press Enter):
Disk /dev/sda - 119 GB / 111 GiB - Adaptec Array
Disk /dev/sdb - 5991 GB / 5579 GiB - Adaptec Array
Disk /dev/sdc - 5996 GB / 5584 GiB - Adaptec Array
Disk /dev/sdd - 27 TB / 25 TiB - Adaptec Array -> this is the one with problems (I use EFI_GPT] to display th
Disk /dev/sde - 256 GB / 238 GiB - ATA SanDisk SDSSDP25
Disk /dev/sdf - 1000 GB / 931 GiB - NVMe Samsung SSD 970

Analyze gives me the following information:

Disk /dev/sdd - 27 TB / 25 TiB - CHS 3403871 255 63
Current partition structure: Partition Start End Size in sectors No FAT, NTFS, ext2, JFS, Reiser, cramfs or XFS marker
1 P MS Reserved 34 262177 262144 [Microsoft reserved partition]
1 P MS Reserved 34 262177 262144 [Microsoft reserved partition]
2 P MS Data 264192 17888805957 17888541766 [Basic data partition] No FAT, NTFS, ext2, JFS, Reiser, cramfs or XFS marker
3 P MS Data 17893405845 46871344276 28977938432 [Basic data partition]
3 P MS Data 17893405845 46871344276 28977938432 [Basic data partition]

Partition 3 works just fine.

Partition 2 is the one with the problem - and has the eroror message "No FAT, NTFS...marker".

I have not enough free space left in the system to backup the appr. 8.5TB - so can someone help me how to proceed without doing additional damage... ???

How to tell the partition its NTFS ?

Please help :-)

What is the exact configuration / type of array behind the label "drive sdd" (Adaptec array)?

Please post the Testdisk log file. What does Testdisk says on the screen when searching for partitions?
Are you able to enter those using "list files"?

2 P MS Data 264192 17888805957 17888541766 [Basic data partition] Can't open filesystem. Filesystem seems damaged.

Doesn't sound good.... I added some disks to the controller to have enough diskspace for the testdisk image, problem is that I did a verify/fix on my adaptec raid controller and that hangs at 66% for 10h now.... and I know no way to abort this. Shutting down server didnt help and i cant find an option in the maxview storage manager. Even the commandline tool seems to have no option to abort the verify... when something hits the fan its either a small pretty bird or sh*t...

Rebuilding the array after including a healthy disk would be my first priority anyway.
