How to retrieve lost drives?
Posted 9/8/16
One day I turned on the PC like usual, and my D and E drives suddenly disappeared, the only drive that is visible and accessible is the C drive.

I don't have any important data on D and E, but it just means I lost 250gb of storage.

I tried reading online guides, but there are so many technical jargons that it confuse me further and discourage me from even trying to fix the problems. Can anyone give a "How-to-retrieve-lost-drives for Dummies" run down? I don't have the backup CD anymore.

What operating system are you using?
Do you want to try to retrieve your lost data or are you happy to just get some blank storage areas back again?

Okay. First off I am going to keep my language as simple as possible as you mentioned above that you became confused by some of the technical websites you visited. Please don't think I am being patronising as it is hard to guage the right level to aim at in an internet forum.

I am working on the assumption that you have 1 hard disk, which is normally partitioned into three sections, C, D and E. If you think you have more than one hard disk in your computer, please let me know.


    1. Right click on your Start menu button and choose Control Panel.
    2. Go into Administrative Tools
    3. Go into Computer Management
    4. Go to Disk management (if you get an error that you don't have enough permissions, close Computer Management then right click on the Computer Management icon and choose "run as administrator" - you will be prompted for your administrator password).
    5. Disk Management should show you a picture of your various hard disks cut down into chunks. Some chunks will have drive letters (eg C drive) while others will be listed as unallocated space.
    6. Please reply here with:
    a. the total size of your Hard disk reported by Disk Management (should be on the left hand side listed something like "Drive 0, Basic, 500GB, online)
    b. a list of the chunks that your disk has been split into (I need to know which chunks have a drive letter or description and which are unallocated. I also need the sizes of each chunk). It is important that you list the chunks in the order that they appear within Disk Management.

I won't think you're patronising, I really prefer simple language for this, because I have a hard time with computers, if anything I really appreciate you trying to help me retrieve my drives.

I decided to take a picture instead of typing to make sure there's no mistakes, Here is a screenshot:

Ah. It looks like you have at least two hard disks. Disk 0 contains the C drive and appears okay. Disk 1 hasn't initialised but is 128GB in size.

Are you sure that you lost about 250GB of space? If so, that would suggest you have three hard disks installed, each of 128 GB. The second and third disks would have had drives D and E but are not responding.

As it is a whole hard disk that isn't working, then there could be several different problems in play. However, as long as you don't mind losing your data we can jump to wiping the disk and setting it up fresh.

Right click on Disk 1 and you should hopefully get an option to initaillise the disk. Select this option and you will probably be prompted to format Disk 1 (make absolutely sure that you are formatting the right disk as this will wipe any data on it). I would advise formatting as an NTFS drive, as that is best for larger sized disks.

Post another screenshot of where you get up to and I can give you some further instructions.

250gb wasn't an accurate number, it was just a guess, I don't really remember the exact capacity of my drives.

I tried to do the step you mentioned... but this message comes up

An I/O error often indicates a problem in the connection of the disk to the computer.

Are you using a laptop or desktop computer?
Do you use external hard disks or are they all built in to the machine?
If you use external disks are they connected with a USB cable?

It's a desktop computer, and it is internal.
I'll open the case and check the connection...

I tried detaching and reattaching the drive that doesn't work... and it's still not recognized. So I'm just going to keep using this PC on my C drive...

Thanks for your help though.
