Dear Fingers, Sluc, OtheHill, DAVEIN-CAPS, thanks a million for your much-valued advice, good counselling and tremendous all-round help.

This is just to let you know that I am now up-and-running again; albeit with a new Dynamode outer case, plus leads and plug, to contain the disc and what-have-you from my old Maxtor External Drive.

The very fair and kind gentleman (a Muslim by the way), at my local accessory shop, got his guru to inspect the Maxtor device, overnight, and - as he suspected - the works inside had been jolted, when it hit the lino-tiles in my lounge, having slipped off my desk about four weeks ago, and hit said tiles with a loud bang.

I took it in on Saturday evening, and - just as he promised - it was ready by Noon today, and when I connected it up at home, all was found to be working, and in tip-top condition.

Thanks for all you kindness, in coming to my aid, dear pals, and please know that I will never forget you...and, particularly when I'm downloading chapters of the three books that I have written, over the past 19 years; all of which are due to go to the publishers, after the chapters have been collated.

Renewed thanks.

Gerry.

Many thanks, Sluc, for your much-appreciated help. I've gone over the troubleshooter instructions, but - when I identified my device - it said *Your device is working perfectly*, so my problem must lay somewhere else. Renewed thanks for your great kindness in helping me the way you have. At least I now know that the device is not busted; well, as far as the troubleshooter is concerned, that is ! I'm not sure where I go from here, but this certainly shows each of the two external drive specialists, who did diagnostic tests on my device - and told me that I needed to update 16 different drivers - were rather wide-of-the-mark, in the outcome. Best regards. Gerrykins.

Does the drive show up in Disk Manager? If so what does it say? If it is shown but RAW, there might be a way to recover it.

Yes, Fingers, but it says *your device is working perfectly*; the device being listed on there, but even so, I can't get it to appear
on My Computer, as it used to be, when it was marked *E* drive.

I guess this must be a difficult one.

Thanks, nevertheless, for your much appreciated help.

You responded to fingers indicating you went into Windows Disk Management. If so, go back and you will see multiple drives listed. Your main hard drive, your optical (CD/DVD) drive, and possibly the external in question. If the external drive is listed there by size or name, copy and paste or type the information listed after double clicking on the listing.

Many times a drive will show in Disk Management but not in Windows Computer.

This is what I gleaned from Windows Disk Management:

Device Type Disk Drives

Manufacturer Standard Disk Drives

This device is working properly

Then under drivers I got:

OK, that information is evidently for your INTERNAL hard drive. Your EXTERNAL hard drive is a Maxtor brand.

Is the WDC (Western Digital) the only drive listed in Disk Management? You should also have removable drives like your CD drive and possibly flash drives and the Maxtor. The Maxtor may be listed as External USB or Mass Storage Device.

Thanks for your further much-valued assistance OtheHill, but - having searched those pages again, and found only internal DVD drives, and no mention of External Drives, least of all Maxtor external storage - I beginning to consider the possibility that I might have unwittingly uninstalled the Maxtor device, when I cleared some unwanted tools from my list, about a month ago.

The fact is, there is no mention of the Maxtor - nor trace of it have having ever been on my computer - anywhere.

I guess I'll have to give-up, and take my tower to a computer shop and risk getting ripped-off for doing something that - were I as capable as you on IT issues - I perhaps would be able to do myself.

I have the chapters for three books on that external device - which represents thirty years work - so I don't want to lose any of it, and that's for sure.


Thanks for your valued help, and guidance. Gerry.

First, try the external drive on another computer.
Second try another USB cable, it is possible that the cable it bad.
Third, If the external uses an external power supply, verify that it works, If the drive uses a 'Y' plug with two USB plugs on one end, make sure both are plugged in.
Fourth, Try a different USB jack on the computer.
We are trying to narrow down the possibilities here. Each test, check in Computer and in Disk Manager for the drive. If it at any point shows up in Disk Manager but not in Computer, let us know exactly what it says as this is important. If you take the drive in for service or testing, bring just the drive and any cables, power supply, etc. it came with. You will not need your computer to test it, they will use their own.
In the future, ALL important files need to be on at least two drives for safety. They can be on your internal drive, your external drive, a stack of DVD's, and/or another computer. As you are finding out now, one drive is not safe enough for a number or reasons.

Thanks very much Fingers for these really helpful and positive solution options, which I will act-upon, as directed, and then come back to you, with the outcome.

You have been really helpful, and I'm most grateful to YOU, and to this wonderful website, for the help I have derived as a result of joining it.

I'll come back, and do as you say, where taking only the device and the attendant cables with me, if I have to go to a PC repair shop; this, only after I've tried every other option first.

Renewed thanks to YOU, Fingers, and all on this site who have been kind enough to help me with this vexing issue.

When you connect the external drive, can you feel if it is turning or not? If it is turning then there may be hope. Taking it to a shop at this time is premature. Try all that fingers has recommended.

Have you tried disconnecting and reconnecting the drive?

Even if you inadvertently did something to the files on the drive, it still should appear in Disk Management.

BTW, did you open disk management to full screen, sometimes the last listed drives are not view able in the default window.

Hello OtheHill, when I connect the external drive, I can't feel anything, but I can *hear* a pulsing sound; one much akin to the sound emitted when a 78rpm record was turning on an old gramophone turntable.

I tried disconnecting and reconnecting the drive, but nothing other than that pulsing sound seems to be happening.

I didn't open Disk Management to *full screen*, but I'll try that now, and report back.

Many thanks for your much-appreciated support and counsel.

Latest: I've just opened each section on Disk Manages and Storage, to full-screen, but there is no mention of Maxtor device, or even external storage !

Over to you. Gerry.

Gerry.

OK, first of all, are you connecting BOTH USB cables to working USB ports. Preferably on the rear of your computer? See the link below for proper connection.

http://www.seagate.com/files/suppor...

If you know how to enter the BIOS (setup) screens, you can verify the voltages coming from your power supply are with specs. The +12V, 5V & 3.3V should all be within +- 5% of stated values.

I assume you have important data on the external drive?

You indicated above that you did something to this drive recently. Can you explain what you did at that time.

Thanks, OtheHill, yes, you're right, my device uses a power cable, and then a connection cable; the latter bringing-on the green light, after it has been connected, but not before.

I called at Maplin's on my way home yesterday, and the assistant there suggested I renew the URL lead, but confided that this might no solve the problem, and that, in the end-game, I might need to get an engineer to open the outer casing, and examine what's inside !!!!

I'll keep investigating, and thanks for your much-valued counsel.

Opening the case of the external drive is your last resort so wait a bit for that. Internally it is simply a hard drive so it can be plugged in as a secondary internal drive on nearly any desktop computer. In this way you would void any warranty on the external drive but it may recover your data which may be more important. This would be the case if the drive itself is good but the electronics within the case was bad. You would first probe the labels on the drive for small sound 'soft' spots that are the label covering the tiny screws that hols the case together. Removing the screws and slitting any label with a modeling knife that covers the seam between the case halves would be the next step to opening the case.
First though would be trying new cables and trying it on a different computer.

By the way, my Muslim pal, told me on Saturday that there would be nothing to pay, were he to find - on opening the case - that it was irreparable, and all the date inaccessible.

However, if he said it would cost £45, if he found he could put the old unit into a new case, and this is what he did.

I paid him £45, and gave him a £5 tip besides, since he has helped me no-end with his efforts.

Best wishes. and thanks again fellas !

Glad to hear things ends on a happy note for you.

Now, be sure to make a backup of that drive before the same thing happens again. You should always maintain at least two copies of any files you want to keep. More if the files are irreplaceable. I use CDR or DVDR for more permanent archiving of things like family photos, etc. Also, you should be backing up your primary internal hard drive on a regular schedule.

Windows 7 has a built in app to backup your entire hard drive. The advantage of course is to save you hours of your time to re-install Windows plus all your programs, drivers, settings, etc.

Buy a second external drive. Preferably a 3.5" with external power to keep on your desk. You can perform complete then incremental backups on a schedule.

Will do, OtheHill, Dear Friend - that sounds like darned good advice - and thanks very much for suggesting it.

The guy who fixed-up my device, by inserting the business-end
into a brand new 3.5 Dynamode, has loads of similar models in
his shop; the prices of which range from £35 to £85.

He insisted that, were I to buy another external device, I only needed to go for a 3.5, and no more, since - on my Maxtor external storage device - I had only used up about on 8th of its capacity.

Thanks for all you help, Dear pal.

3.5" is the platter diameter, not the capacity. the reason for a 3.5" drive is they are not as portable because they have an external power supply and only require ONE USB connection. They are more reliable because of that. The capacity needs to be about twice your internal hard drive capacity if you intend on performing total backups.

Thanks for this, OtheHill, but of the *cake* illustration on the hard-drive, my usage amounts to a segment corresponding to about on eighth of the available capacity, and on that Maxtor external drive, even less than that.

Many thanks !

By the way, the man at the shop showed me some modern external drives that are not much bigger than 4in x 2in x 2 in depth, but I passed on those, which cost £85 from him.

Many thanks.

I will rephrase then. You need at least twice the capacity of the current and expected future data on your internal hard drive. Double is so you can always have one usable backup file without overwriting anything.

Drives with extenal power supplies are more reliable. An internal fan is also desirable.

When using the Windows Back up (which I use) check off the feature to make an image of the drive as well as the back up. Then make a Windows 7 Repair Disk. With this combination you can recover individual files, all files after a reinstall, or use the disk image to write the entire drive over or to a new drive in the event of a complete failure. Then you load the most recent back up to get up to date. Update the drive image 2 to 4 times a year and regular back ups at least weekly or anytime important files are saved.
