Windows 8 Laptop Drive cleaned using Diskpart Clean

#1 Post by lmorris34 » 26 Jul 2018, 09:21

Hey everyone,

I got ASUS X205T to repair because it was not starting up (OS WIndows 8.1 possibly SSD) Refreshing the PC did nothing. I unfortunately did a diskpart clean (diskpart --> select disk 0 --> clean) from the command prompt.

I realised this was the wrong way when I tried to follow these steps (which I should have done first) to repair the BCD

I am able to launch the test disk program from command prompt on my windows 8 USB, however its detecting the partition as EFI/GPT
The recovery drive (C:) seems intact and unaffected by the diskpart clean

I do not want to risk further corrupting the drive and data, since data recovery is not my specialty.

What is the best way forward from here?

Thanks in advance!

Recover all your partitions first. Once it's done, try to boot from your disk. There is a chapter about it in the pdf.

Thanks much.

Tried this and it is attempting to recover the partitons, however when i try to boot the same error occurs.

Writing to Intel/PC partition table did not work as it is detecting EFI/GPT

Currently doing a deep search setting it as EFI/GPT however I am getting warning messages with mismatched heads/cylinder & sectors per track. (tried to upload a JPG but it is failing)

Would I need to adjust the geometry of the disk? should I still write the partition table?

Thanks again for the support!

The geometry of the disk has no impact for disks partitioned using EFI GPT.

Thanks man.

As it stands now I think I wrote the wrong partition table because the laptop is not even detecting the HD :cry:

when I boot testdisk it shows the 3 partitions with the mismatch errors on one partition. and if i try to go to the disk directly outside of test disk it says the drive is corrupt

Currently I am trying to find a correct partition table to write so at least it can detect the HD

Also, i am getting a message saying the a partiton cannot be recovered, and to check the HD Jumper settings.

What can be done if anything?

Forgive me with the multiple questions, Im just really new to this advanced data recovery stuff

Thanks again!

also, all the partition types are coming up as MS Data. What is the correct partition types? (EFI/GPT Selected)

Hey everyone, so Ive been trying to fiddle with this drive, and here are my findings so far

Tried partition lists

2048 206847 204800 - system
206848 44292095 44085248 - No Name
44292096 61069311 16777216 - Recovery

missing partition - 27514881 44292096 (structure becomes bad if i try to add this partition)

rebuild BS cluster 18221 used

PARTITION CANNOT BE RECOVERED - 61069311 77846526 16777216

deeper search

heads/cylinders mismatches on 6174 (Boot) & 16777216 (Recovery) (I know you said this does not affect EFI drives)

Using Intel/PC Partition
One EFI GPT Partition not bootable consisting of
FAT32 - system
FAT 32 LBA - NO NAME
HPFS NTFS - RECOVERY

test disk has found 14 partitions and I can only write thsose 3 together (first 3 mentioned above)

I am beginning to believe this drive was crashed way before I did diskclean
