Files invisible on backup disk

Hi
I have a 160GB Iomega drive for storing my music and backups. It's worked reasonably well until now (though sometimes I need to restart PC to get PC to see it...)

The big problem is that since last week it 'looks' empty. There's ~100GB of data on it but if you open the drive in Explorer, it looks empty. It says there is only ~50GB free, so that means it's not been wiped, but I can't see the files.

If I save something new, it is visible.

Help?

No... Not Physical Damage...

Now, If your last resource will be to format it... then run CHKDSK F: /F and see if you can get ANY info at all... then copy that info to a Temp directory maybe in C: and then format the F: drive, and when finish, put what ever chkdsk found back in F: (after format that is)...

Go to the drive in windows explorer, go to tools, folder options, view and make sure for that folder that you can see hidden file and system file.  Maybe the attributes got hosed on the drive.  You can also try the old dos XCOPY command from a dos prompt (type start-->run-->cmd) and try xcopy /s x: c: where X: is the assigned drive letter of the iomega.

Oh sorry, I thought you wanna recover the space in the HDD, not files... try unistalling the Drive from Device Manager...

On Computer right click on Properties... Hardware tab... Device Manager... select device... unistall...

If you installed some drivers, try and see if you can unistall the drivers (programs) from Add new software...

Start... Control Panel... Add remove programs...


the install all drivers/programs that came with it...

Try GetDataBack and see if it will recover files.  There is a trial version.

Hi all,

jdietrich your command doesn't work (syntax error/), and anyway, the c drive is much smaller than the f drive.

whatboy - tried that but no joy

willcomp - tried but nothing found

riteheer - how? sorry, i'm stupid!

Was GetDataBack able to see partitions on drive?  What partitions (how many and size) were listed?

teallachAuthor Commented:

teallachAuthor Commented:
riteheer - I think so. If I type F: then return, I get prompt

oK from the f: prompt,  type   dir/w and then hit <enter>  This should give you a list of directories (folders), if it does look thru them and see if the stuff you are wanting is in there, let me know the results and we'll help you from there...
Also, right click on my computer, then choose manage, then go down the left side and click on> disk management, the post the info on the f: drive here.

asian_niceguy - I use a wheelchair and can't get under the desk to unplug the drive. On Wednesday I have a helper here and we'll plug it into my laptop. Thanks!

It is a 160GB drive. I know there is about 90GB of info that I can't see or access. Thisis music and various backups.

Since the disk began appearing epty, I've saved another backup of 7GB and a text file named 'test'

When I did the dir/W I get this:

F:\>dir/W
 Volume in drive F has no label.
 Volume Serial Number is 543A-5738

Damn... Now we now... the disk is corrupted... now if you proceed with the "chkdsk f: /f" it might repair something, or it might do more "damage" (not physical), so unless you have money to spend for professional recovery software, I suggest you do, most of the trial recovery software will do nothing, it will only tell you what you already know... so I guess it is up to you, if you want to proceed...

Sorry, advice is to do a non destructive recovery.

willcompCommented:
In my experience, if GetDataBack fails to recover the drive, only other option is a data recovery service.

See if you can remove drive from its housing and connect via internal IDE cable.  That might (very small might) allow recovery software to do a better job of reading drive.
