Unallocated Drive

mkolivas · 11-09-2009, 05:48 AM

Good Day everybody,

I am facing a problem with my hard disk as below...

yesterday my hitachi dk23eb-40 all of sudden stopped working and my pc couldn't boot, what i did was to remove the drive and connect it externally to my laptop. the thing is that i cannot see the HD under my computer and in the disk management it shows as unallocated!!!

i also downloaded the testdisk application and i followed the steps as shown in this post http://www.techsupportforum.com/1163140-post1.html

everything goes fine until the step F (as you can see in step6 screenshot) were the analyze goes until 20% and stays like this for hours!!! so i thought that something is wrong and i removed the usb and i plug it in immediately, after that it reached the 100%!!! and i found what you can see in step7 i select "write" but at the end i am getting an error which says Partition: write error

can you please help me with this? i have important data in my drive (2 partitions) and i cannot stand to loose them...

Try deep scanning with partition find and mount ( www.findandmount.com ) If it finds the partitio it will let you mount it as a read only volume and copy the data out to another disk.

thanks a lot for your quick reply,

i downloaded the find and mount application and i am sure there is something wrong!

as soon as i run the application, it automatically recognizes the 2 drives, the main one and the one that i have problem with (which is connected as external HDD) after double clicking on the damaged one and select thorough scan absolutely nothing is happening! after that i tried normal scan, quick scan but nothing...

any ideas please? what am i doing wrong?

There is no real progress indicator, and the deep scan could take several hours, let it run till you ge4t the completed dialog.

ok we have an update...

i had to run the find and mound as administrator in order to work!

i am trying to do thorough scan and for tha past 3 hours is at 0%
the hard disk is doing some noises as usual but nothing else...

shall i leave it like this? any suggestions please?

What kind of noises?

mkolivas · 11-10-2009, 05:31 AM

it is a continuous noise like reading and then a tik, reading and tik. but it goes like this after a while. as soon as i connect it to a pc, it seems its spinning and reading, i am getting this continuous "noise" when i go to disk management for example... is it helping?

please i must try everything

You can record it, upload it to a site and then post the link, zipping may not help reduce the size much. See if it sounds like any here... http://www.datacent.com/hard_drive_sounds.php Based on your description, it sound slike a head failure - the drive is trying to init but not able to read the service area of the drive.
