Windows 7: Hard Drive Unallocated

19 Mar 2011   #1

Windows 7 Home Premium 32-Bit - Build 7600 SP1
Hard Drive Unallocated

I have one hard drive which has two partitions. One partition has my OS/Programs and the other has my Docs. I have a second hard drive that has two partitions which are my Macrium backups for the first hard drive. Today I looked and my back up drive shows unallocated. I am confused as to how this could happen and what can I do to correct it. Thanks,

Looks like you somehow deleted your Disk0 because that screenshot shows that there is nothing on that disk.

That is unless its an error in Windows and the partitions/files are actually there.

If they are gone you could try recuva to try and get the files back.

Have a go at Partition Wizard, right click the HDD and click "Partition Recovery" first to see if it helps.

I'd definitely go with the bootable Partition Recovery Wizard option. Maybe the file system was damaged.

Thanks for your input. Since there was only my Macrium Image backups on the disk, I just reformated and made a new image. It does concern me that it happened. If anyone might has a guess as to why, I would appreciate it. I guess I could blame SP1 for the problem

Sometimes Disk Management gives incorrect readouts. You can cross-check it with free Partition Wizard bootable CD as Michael suggested.

unallocated hard drive space
I have a 5610Z Acer Aspire with Windows 7 (32 bit). I pulled a very boneheaded move getting to upgrade from Vista. I deleted my D:drive (50 G). I back up to a 500 G external hard drive. Is there a way to add the 59G to C:drive where I could use the space. Thanks Brightlight864:o
