Hi, please help...

My 3 month old Buffalo external hard drive has developed some serious issues- On running PC Inspector I get the following message

"Error no.27
drv: 129 Lba:0 Blocks:2"

Every time I click "Ignore" the Lba value goes up by one.

I have tried freezing it, but no joy. Any ideas ?

Thanks

What is the drive's actual status right now? Does it appear in explorer and have a drive letter? Does it appear in Disk Management and what is its status there? Does it appear in Device Manager?

Have you tried it on another machine?

When you say "developed", what was the exact sequence of events?

Can you hear it spin up?

Is it your impression (if you have one) that it is a software or hardware problem?

This is why it is always necessary to have data backed up.

Thanks guys for your help,

The drive is recognized in device manager and the drive icon is there on the bottom right, but not straight away...

When I attach it the light blinks once, I can then hear it bleeping faintly, which lasts for about 10 mins...only then does it become recognized...When running pc inspector the light blinks once every 3.5 secs, but is otherwise off and the drive is silent... as if its pretending to be dead !

Thanks again

Check Disk Management.

Right-click Computer > Manage > Disk Management

or go to Start > Run, and type:

diskmgmt.msc

What does it say about the partition?

Have you tried it on another machine?

I have tried it on another pc ( win 7 and vista) It had been working on both previously

Before it blanked out, I recall hearing the faint bleeping noise for about 2 days

When it bleeps and if I put it to my ear I can hear a whirring noise which goes up and down, as well as a faint clicking sound, these noises lasts about 10 mins before it is recognized

Thanks

Do you have enough room on your main drive to hold all the data from the external if you could recover it? Or any other place to move it to?

It sounds like the file system (or partition) is damaged. The files are probably still intact.

But....even if you manage to get access to them, you will need to back them up so this doesn't happen again. So give some thought to that. And again, even if we get access to those files, it would be best afterward, provided the drive is usable, that we clear it and repartition. So again, the data would need to be backed up.

We can start by simply trying to restore the partition. This tool is not the easiest to use, but works miracles at times. Most times you simply choose the defaults. You need to remember to write the changes to disk when at the end. You can read the docs for help, but it will involve some guessing. But, and this is a big "but", if you make a mistake, you won't lose your files. So you can go back and try again. It only affects the partition table and not the files and folders.

Testdisk (for Windows)
Testdisk on Live CD (Try the CD and boot from it if you can't access the drive with Testdisk through Windows. The CD uses Linux drivers and they may have more success. It is even possible that you could access your files from the CD, but you would need to have somewhere to move them to. But you could try the repair from the CD and then try again to use the drive in Windows.)

-----------------------------------------------------

Here are some others that you can look at if Testdisk fails to be of use:

Free:

Diskinternals Partition Recovery
Partition Wizard Boot CD
DriveRescue
Testdisk Boot Disk
Partition Find & Mount
Free DTIData NTFS Partition Repair Tool

Commercial:

Diskinternals Partition Recovery (Demo)
[email protected] Partition Recovery
Bootmaster Partition Recovery
ZAR Partition Recovery
DIY DataRecovery DiskPatch
Partition Table Doctor
Nucleus Kernel Recovery for NTFS
