What to do if your external hard drive does not show in my computer

  1. Easy to FIX

    Right click on my computer
    Choose MANAGE
    You should see your ext hard drive under the list.
    Right click on it, and choose CHANGE DRIVE LETTER
    Choose anything, but I recommand something higher than M:

    I've seen this problem with alot of STORAGE DEVICE

    It happen more often with Laptop because they usually have Card reader.
    So it makes couple drives like e:, f:, g:.
    Storage device tries to install themself with the drive letter next to CDROM
    c: - HD1
    d: - HD2 or CDROM
    e: - Mass storage device (maybe for card readers)
    So your external HD tries to have the E: drive (probably a bug)

    See ya

    Still having problems.


    I hope you can help me.

    Bought a laptop SATA HDD to replace my old one with. I stuck it in an external case in order to back my current HDD onto the new one. However when I connect the new one in the external case it does not show in my computer although the computer has "installed" the the "new device" and it shows up as being connected in the hardware list in the control panel. I simply am not able to access it or manipulate it. The advice given above does not work as it is not available in the DISK MANAGEMENT list.

    Can anyone help me.

    Thank you.

    A friend of mine figured it out. I had been an ***** and not scrolled far enough down the list of drives to find my new one. Sometimes you just deserve a smack :S

    Thanks for all the help.

    Simpletech 500gb Ext HDD cannot be seen in my computer

    I have a Simpletech 500gb external hard drive and it was working fine for a while. I was using it mainly to store and backup my data and regularly connected it to my PS3 to watch movies. When i was trying to adding more data onto it one day, a message came up saying that the disk was full. I pressed cancel thinking that I would need to remove some files to make room. But after i pressed cancel, my external was no longer shown in my computer. It still mad the noise when I disconnected and reconnected and had the safely remove device icon in the right tray. I tried to research on the problem and called the company for some support. The technician said that it was because of the PS3 that it doesnt show in my computer, but i was thinking it worked fine before. Anyways, he told me to right click on my computer and click on manage. Then goto disk management to format my external. I did just that, and formatted it but after around 5-6 hours it was still formatting so i cancelled it. It now appears as Local Disk F: instead of orginally E: and everytime i try to right click or double click on it, it freezes the window and makes it not responding.

    Any help will be GREATLY appreciated!!!!!!

    Thanks for the help

    I did everything you said. Worked good except for one thing. When I went into Computer Management it showed two drive letters, (C): and (D):. It showed the the new hard drive below those as Disk 1 and Unallocated. It would not let me change the drive letter. I guess because it had no letter to change. So I just partitioned it with the full amount of available space and that worked. I hope that was the right thing to do. Thanks again.

    The same thing happened to me too.... Actually, I was be able to use my external hard drive before (btw, it's a Western Digital external hard drive). I was connecting it to my friend's desktop, and put it standing on the floor. After we're done using it, I accidently hit it and it fell flat on the floor. The next thing I know is that when I plug the USB in my desktop, it didn't show the drive in my computer anymore. It showed the USB icon on the taskbar. I opened Device Manager and it said the device is working properly, but then I opened Disk Management and it's not in there. Can someone please help me??? =[

    Seagate Ext. HD

    Hi there,
    I'm having the same problem as the previous post. Just purchased a 500g Seagate External Hard Drive. It was working fine for a couple of days but one day I rebooted and couldn't find it anymore! I tried the Seagate Diagnostic Too "SeaTools" and it didn't recognize it. Even my Disk Management doesn't see it. It powers on fine and doesnt make any wierd noises either.
