TestDisk appears Partition : Read error

#1 Post by jk22 »

Yesterday, my laptop went to checkdisk on boot and after it finished I cant access my laptop 2 partition which is located on Western Digital 1TB harddrive and its showing RAW like 0 bytes. I have very important data on it and I want to get back all data.

After proceeding on Analyze optin on TestDisk it says : Partition : Read error

Can you help on it.

Regards.

Partition read error means that your partition table is not readable.
Can you check your disk using crystaldiskinfo?
http://crystalmark.info/download/index-e.html
Please use the portable version.
It's intended to exclude bad sectors!
What's your OS?

Did you select the right disk?
1 disk at the upper area on the left of your snapshot displays caution.
You can choose another the disk at the menu bar and disk!

How is your disk listed in your disk management console?
At least it should be initialized.
Disk size should match also!
Might be possible that only your MBR is not readable?
Can you run TestDisk / Analyse and Quick Search?
When partitions are found, select them and press p to have a try to list your data.
If no partition would be found, please run Deeper Search too.
Deeper Search searches additional for a backup of a boot sector and can find more partitions.

Did TestDisk find any partition and which one lists your data?

I am not sure about that. Maybe its possible. How can we fix MBR into readable ?

I have done quick test and deeper scan but no partitions found.

Furthermore, I have to select 931GB drive like /dev/sdb or I should select each partition like M or N as listed on Disk Management ?

Read error can cause that testdisk hang or scan speed can slow down drastically.
Also it depends on how many do you receive?
At least crystaldiskinfo reported that your disk is GOOD?
Read errors which are not physically damaged are often soft bads.
It can indicate that your file system is damaged?
Might be possible that you need datarecovery software which reads underlying data/files?
When testdisk find partitions.
You should select each partition and press p to have a try to list your files.
Testdisk can list data, even if the file system is damaged.
In case, I don't recommend to recover the partition but when testdisk lists your files you can copy them off of your disk to another healthy disk or partition.
When you receive too much read errors you should consider to clone your disk.
