External Hardrive Question

By bmoore ·
I have an external WD hardrive which I have partitioned and have saved my personal and backup files to on my desktop computer but when I hook it up to my new laptop (xppro too) it wants me to re-partition it and format the harddrive and I cannot access the information that has been saved..Once the hardrive is set up, how do I access it on another computer?

What type of external HDD is this?

by OH Smeg In reply to External Hardrive Questio ...

If it's a 2.5 inch type you need to plug in both USB Plugs so it has enough power to run on the NB.

Sometimes with new NB's they don't have enough power available at the USB Ports to drive a USB Drive so if you are unable to get it to work with the 2 USB Plugs try connecting a Powered USB Hub to the NB and then connect the External HDD to the Powered Hub that should provide enough power to let it run properly.

What type of external HDD is this? - Related HDD problem, cn you help?

by pagwu In reply to What type of external HDD ...

Perhaps you may have some opinion or trick to share with my HDD problem. I have a 300g NexStar external HD that my Toshiba Laptop running Windows Vista Home Premium does not recognize. Could you please advise me what I can do to have my Laptop see the HD. Please provide step by step detail how to check for any recommendation that you want me to perform. Like checking for the correct usb hub, changing what to what and also how to/what to look for BIOS seetings. Hope you see were I am going wit this.

Thanks

Vista has a known problem seeing some HDD's that it hasn't partitioned

by OH Smeg In reply to What type of external HDD ...

If there is nothing on this drive the easiest option is to use the Drive Management to Format the HDD and then it should be available to Vista.

However if you have data on it and it's a NTFS Partition you will need to import the Drive into Vista. The help files provided with your OS will tell you how to perform both of these functions and they would be the best way to look up what you can do and the correct way to do it with your OS.

I have very limited experience with Vista and have only used the Enterprise version for a very limited time as it fails to meet the requirements of a reliable Business application yet so I have not deployed it as yet just like XP wasn't suitable when it first hit the streets back in 2001 as there where way too many problems with it and even worse not enough software that would run on the new OS so we waited for SP1 or latter to become available and have the full range of our Mission Critical Software work on the New OS and a complete Range of Drivers Available. While Vista Drivers are much better than they where in November when I got my Volume License Copy they are still not perfect and some Hardware makers are still offering Beta Drivers those these are now mostly gone today but there are a few left from some M'Board makers.

So for this reason we don't support Vista as a Business OS currently and leave it for Home Use which we don't support. Maybe next year we will start to offer support for Vista but there are still quite a lot of problems that need ironing out and an even bigger problem with Office 2007 in the backward compatibility stakes so that is another item that we do not support as yet.

If you have data on this drive I would suggest connecting it to an XP computer establishing a Peer to Peer Workgroup and transfer the data across the LAN and then when you are certain that you have everything transfered format the HDD on the Vista OS. That way you should be able to use the external HDD with your copy of Vista but it may prove useless with older versions of Windows because of the security built into Vista protecting your files on the external HDD.

Vista has a known problem seeing some HDD's that it hasn't partitioned

by pagwu In reply to Vista has a known problem ...

Thank you OH Smeg for your insight. Let me say that I had the HDD originally on a Dell Inspirion E1505 Laptop running windows
(Media Center Edition) XP Pro (SP2) machine for a while, put the HDD away for some time, and when I came back to use it again, XP did not recognize it either.

So, the question becomes, do I have a bad HDD and how can I really be sure of this?

Are tools that I can use to conclusively determine the health of the HDD? What are my options to recover my very important data on the HDD?

Any help, suggestions will be highly appreciated.

Thanks

OK first thing is to find a XP computer to test this on

by OH Smeg In reply to Vista has a known problem ...

As it's an external Drive it should have 2 USB Plugs on the Computer end of the cable if you are using a NB make sure both of these USB Plugs are plugged into separate USB Sockets not different Sockets on a USB Hub unless it is a powered USB Hub.

The Modern NB's have very little power available at the USB Sockets to increase Battery life so you need both plugs plugged into separate USB Sockets to get enough power to run the drive. If you have a Powered USB Hub that takes it's power from the Mains you should be able to get away with just the 1 main USB Plug as the second one is only there for extra power. Also if you only have 1 USB Plug make sure to plug this directly into a Powered USB Hub so it has enough power to run the drive properly.

If you hear a clicking noise from the drive this is a good indication that the drive is shot but depending on how important the data on it is it is possible to recover the data but this is going to be expensive. The last 40 GIG HDD that I had this done to cost $46,000.00 AU to recover the Data but because this had Tax Records on it for a company it wasn't really important and the cost of the recovery was a Tax write-off immediately as well.

Now sometimes the USB to IDE Interface can fail and to check this out you need another USB Caddy for this Drive Type and change Caddies. The generally involves destroying the original USB Caddy or enclosure to test the HDD but it may be worth the effort if it's only the USB Interface that has gone bad.

That may allow you to recover your data quickly and cheaply and is an easy test as well but if it doesn't work and you should only try this if there is no noise coming from the Drive Enclosure it may cure the problem or may not have any effect.

If the drive is no longer working there are a couple of ways of testing this the first is to download a copy of the Drive Makers Testing Utility and test the HDD with these External Drives this is done from within Windows and the testing Utility should still see the USB Drive even if Windows can not though you will have to look at what OS the Testing Utility supports as I don't think that many as yet support Vista.

Or you can open the Case place the drive into another computer with a Suitable adapter and test it from DOS. This is really the best way to test things but you need to make absolutely sure that you connect the drive the right way to the adapter or you can destroy the M'Board HDD Controller.

If the drive fails the DOS Test you are stuck with sending it to a Data Recovery House for Data Recovery as you can do nothing with a dead drive. Though sometimes it's possible to rebuild the Partition Information by using the Repair Option with Check Disk but with XP the partition needs to be either FAT32 or NTFS while Vista needs to be NTFS.

Most of these prebuilt External HDD's come formatted with a FAT32 Partition so that they can be read by all computers when they where originally made available including the Mac's so it's better to use a XP Machine to do this initial work.

If that fails to work your only option is a Data Recovery House as the HDD has been damaged either by a Static Electricity Discharge or it's been dropped. Those are the most likely causes of a HDD dieing though there are other things that can happen but they are less common.
