HD problems

:mad: A couple of weeks ago I helped my colleague to choose an additional HD for his video work. He decided upon an external drive for ease of installation and ability to take it to other locations. His local dealer supplied a 160g disc in a caddy, all formatted and tested. I took it to my home out of interest and tried it all. Installing on my colleagues machine gave all kinds of problems. He has both firewire and USB 2. The outcome was that the drive had to be reformatted etc. This happened a few times and the dealer was as baffled as myself and he also reformatted again.

A final try was made yesterday. Reformatted disc. Various photo files and a video file placed thereon. I used the disc on both my PC’s and took it to a friend where it worked fine. Took it to the owner and the machine recognised the disc but still doesn’t read it. Error message - F:\ is not accessible. The file or directory is corrupted and unreadable.

Took the disc back home to my machine and got the same error message. Looked at the disc properties and see the disc shows as FULL but NO bytes and the file system now shows RAW. All that I had placed on the disc was gone. Just a point, all the machines are XP with SP2.

The dealer, who has been very helpful on all this, now seems to think something could be wrong with the machine itself and suggest it is taken to him for investigation. This will naturally incur charges that my colleague can ill afford. I’m really trying to help him.

Any advice here ASAP before the machine is sent for expensive servicing please. Pete

Some thoughts which may help:

If you can put files on the disk and read them on two machines, that suggests the drive is OK.

Does the firewire port on your friends machine work with any other firewire device, eg a camera?

If so, the drivers have been installed: if not, have the drivers been installed?

What does Device Manager show for the firewire port(s) on your friends machine?

This should not be an isssue with XP, but I assume the drive is formatted NTFS? What file system is your friend using?

Your friends machine is not a Mac I assume?

Have you been scrupulous in using the "Safely eject" method for disconnecting it? Doing so should ensure that the files on it are safe. If you've been doing that, then the drive's faulty and should be replaced.

Thank Alan C.
[1] Files OK on 3 machines and tested by dealer. [2] Owner imports video into his firewire ports with no problems. [3] I will checkagain what the Device Manager says about the Firewire Ports (On the edge of my know-how here) All machines on NTFS [4] NO it's not a Mac Tut Tut. Its been tried with both the Firewire and the USB2.

Thanks Alan R I remembered your firm advice about using 'Safely Eject' method. I've really tried hard to be sure about this especially with yesterdays endeavours. It's been connected and reconnected many times on my machines but only on my colleagues dos it foul-up.

Going to see the dealer again this morning with the disc. Pete

Good luck, then.

I know that safety eject is supposed to be essential, but I have never had any problems when I have forgotten - which is a significant proportion of the occasions!

Sorry about the egg-sucking, Peter, they were just the thoughts I had. I suggested the Mac idea because I have come across problems with my firewire drive with a friend's Mac.

I note that Alan R suspects the drive is the faulty party? If so, would it not display the fault on every machine?

Another thought! The drive is the common factor in all tests. What about the firewire lead? Has this been checked by substituting a known good lead?

Device Manager: Right click on the My Computer icon on the desktop, Then select Properties, Hardware tab, Device Manager, in that order.
Look for IEEE1394 Bus Controller; click the + to the L (if there is one).

Are there any !, ?, or X showing - if the port sees, and controls (does it?), a camera, I should not expect a problem. Right click on the entry and select Properties - it should show in a box "Device working properly".

Have you considered the possibility of a firewire controller problems on the owners machine?
I've read many times about various cameras struggling with a wide variety of firewire controllers so could also be the root of this issue?

Like the others have said if the drive only fails after being used on one machine then it's unlikely to be the drive. It sounds like the file system is getting crunched on one machine ruining it for all machines. The data will still be there but the file-allocation table will be stuffed and so the drive no longer realises it. A program like PartionMagic Vn7 onwards may help you here if there is a copy to hand.

Do you have an easy-to-swap PCI firewire card that you know works? If so try it in the Owners machine and see if the results are the same.

Thanks again for all the advice but do read on . . . I reformatted the disc and placed a Word doc on it along with a jpeg photo and some video. Returning to my colleage we brought in another talented chappie. I just gave him the disc and cables to try for himself. Needless to say it worked properly first time. I just guess the rest of us are total idiots. However, we will wait till tomorrow . . . . .

Peter, are you claiming to have been having Village Idioting lessons? If so, where, and how much? :D

Well Alan, I'm sure YOU don't need these lessons, but for a small sum . . . . . However the saga goes on. Went again to my colleague this afternoon and, yes you have guessed, the B****** thing fouls up again. Totally crazy. I just give up. Pete

If you're getting these problems with the disk without it going near the target computer then I'm afriad it's time to get rid of the disk. After all how can it be a computer related problem if many machines suffer the same issue?
You (and many others) have already spent many hours trying fix it and even if you did could you really trust it again for putting any critical data? Even if there was a problem discovered with the PC you'd still be uncertain about the disk.

Will the dealer swap the external disk for a direct or similar replacement?

Vimeous, Sorry, perhaps I didn't explain properly. The disc works perfectly on my two machines, a neighbours machine, the dealers machine (Total 4) but constantly gives major problems on the owners machine . . . (I think I will go into a corner and try to sleep it off) Pete

Peter, why not make him an indecent offer for it, if it works for you? Extra drives are always useful these days.

Peter,

Are you using the same cable with your friend's machine as you use with the machines on which the drive is OK?

Peter's said earlier that he hands over the drive and all the cables, so answer should be "yes".

Well it's baffled greater minds than mine and several others. Re your idea Alan R of just buying the drive from him and letting him start again. Well I have considered that but I dont really need it or the expense. But I would just to help him out.

However he is having one last attempt by letting yet another 'expert' take the whole lot away and starting from square one.
It's out of my hands now but if anything interesting transpires I will let you know. Thanks for trying to help. Pete
