Windows 7: No Space detected on Hard drive

No Space detected on Hard drive

Hi All,

Ever since my hard drive crashed I've finding ways to restore the data somehow but now I'm really lost and at my wits ends. I hope someone can help me!

I have 1 tb external Hard drive. When I plug it into the computer the drive is not registered automatically.

I can see it in Devices so I know the computer is detecting it.

The disk drive is also not initialized in disk management.

Following the thread here disk 1 is unknown, not initialized, unallocated I have downloaded the mini tool partition wizard.

The harddisk has no space detected and I can't run any recovery on it using the tool...

Is there any other way to recover my data or is my hard disk totally dead?

Do not do anything with this HD anymore -- until you have posted a similar thread over in hddguru's conventional hard-drive forum. There are numerous hardware and software level data recovery folks ranging from newbie to professional. Admit that you are now asking for their advice, perhaps even linking to this thread. I have no experience with GPT setup, so I am useless here.
There exists also data-medics forum and recovery force forums -- however, they may lean towards having you send that HD to a data recovery company/specialist; and if you are not leaning that way at this time, consider hddguru forum as the second place to visit.
If jumanji enters this thread -- follow his advice to the letter! :)

As Roland advised, don't try to fix the drive.
Wait for Jumanji help. He is the disk guru.
By now, you have to give us ALL the Buffalo drive specs (Model etc).

Is this your Buffalo drive 1TB HD-PCF1.0U3BB

In all probability the SATA to USB bridge electronics inside the enclosure has failed. That is why it is not even showing the capacity. The HDD inside the enclosure may be OK and the data can be recovered. Unfortunately it is not a DIY project for the simple reason the manufacturer might have soldered the bridge Electronics directly to the HDD to make it compact. ( The HDD may not have the usual SATA connector) So it is not possible to take the HDD out and connect it directly to the motherboard to retrieve the data.

Please discuss the issue with Buffalo Tech Support and find out whether they can help replace the bridge PCB and recover the data or will they recommend any professional data recovery agency for Buffalo HDDs who can do it.

Just for the record and perhaps a 1% chance recovery possible, post a Windows Disk Management screenshot again. But this time try to initialise it as MBR and not GPT(as you had done). Post the error message if any. If initialisation goes through just stop with initialisation and do not proceed further to create a new volume and format it. (Initialisation only writes the MBR code to Sector 0 and does not affect any data in other sectors)

Uninstall the latest version of Partition Wizard and install v9.1 which can be downloaded from
Post a screenshot of how your Buffalo drive appears in it.

If there is a chance of recovery, we shall proceed with this version of PW.( Not free in later versions)

EDIT: Also try with a new/different cable to exclude the possibility of a faulty cable.Try on another PC as well.

Hi Jumanji,

I've tried another cable but it didn't work.

Also tried the initializing it using MBR but an error is shown.

Screenshot of how to disk looks like in Partition wizard 9.1 attached.
