Hi,

I have an external hard drive for my laptop which I use to back up my files occasionally. I have it 2-3 years at this stages and it has been used 5-6 times during that period. I recently connected it to my laptop but for some reasons I could not open some of the files, I disconnected it and reconnected it but then I couldnt open any of the files on it. After I disconnected/reconnected it again the computer didnt even recognise the hard drive. When I go to 'My Computer' the hard drive is not displayed but I do get a usb connected icon in the system tray. When I try it on other computers I get the same result in that it is not recognised.

I am a little baffled as to what has happened as when it was not in use it was stored safely and would not have got any knocks or bangs.

I would appreciate any advice or guidance that anyone can give me.

Thanks in advance

Does it show in the BIOS?

Family and loved ones will always be a priority in my daily life.  You never know when one will leave you.

^ And if it does, have you tried accessing the contents through a Live CD/Linux distro?

If it shows up in either BIOS as Dc3 suggested and or in diskmgmt.msc as Thrillhouse suggested then it sounds like it is probably a software\lead in track corruption problem.

This may do the trick for you in restoring it`s function. Find and Mount.


Disclaimer regarding 3rd party software; Many freeware programs now come bundled with unnecessary add-on`s. Example = Search\Tool bars. Do not be click-happy when installing these type or any other software. Be aware of what you are installing, Uncheck any\all boxes for unneeded\unwanted software. Sometimes this may involve doing a custom install if the option is presented.

Hi Guys,

Thanks for the responses. Unfortunately I don't know how to access it via the BIOS, can anyone tell me how? I tried accessing it via diskmgmt.msc as suggested and it shows up but only as an unknown drive which is unallocated and not initialised.

Should I still go ahead and use the 'find and mount' link?

Also when I connected it this time it went through the process of installing new software but still didn't show up on 'my computer', not sure if this is relevant

Using Find and Mount will not harm anything.

May not solve your problem though.

Using 'Find and Mount' didn't work, although it did identify the hard drive when I plugged it in. What should I try next?

I am not really worried about the info on the drive as I have it all backed up. I would like to be able to use it again but because it is not showing up in 'My Computer' I can't even reformat it.

you could use fixboot in ERD Commander which is free but hard to find because its old. And that will only work if the bootloader is the problem. If it is a physical problem I think it's damaged beyond a software fix.

Edit: Microsoft bought ERD Commander and now it is not free. That is what I am familiar with but any software that can repair your master boot record will work if that's the problem.

When you have disk management open, right click on the drive and select "initialize"

Ok I tried initialising the hard drive from disk management and was unsuccessful.

Is it worth trying to fix the masterboot record?

I am running windows vista but when I try it on an xp machine it is not recognised either.

The brand is Sumvision but I am not sure what model it is. It is around 2-3 years old and around 42GB capacity

oof. Frankly, unless you have something important on it that you need to recover, I would not mess with it and upgrade to a brand name model. (Western Digital, Seagate, Hitachi, etc)
