External HDD does not show up in my computer

post #1 of 13
Thread Starter 
I have this problem but its about my 500gb external hd with data in it that I don't want to lose as well as my other 8gb usb flash drive.

It does not show in My Computer, it does show in disk management but it doesn't show a drive letter and when I right click to change it the only options is delete volume.

It also doesn't show the file system.

So both the external HD and flash drive do not show up?

Yea, it looks like you will have to run some recovery apps on the drives. If you haven't done so already, connect the drives to another PC to confirm that it is indeed a drive problem.
Also, depending on the external HD, you may be able to easily remove the actual drive and plug it in to your internal SATA or IDE.

both drives work on my macbook, but when I switch it to my PC its the same problem. These worked two weeks ago the last time I used them...

before I run any data recovery software I want to make sure that this is just not a problem in windows...since both drives work on my macbook

copy it to the mac and format it in windows?

Try using Gparted to reformat it if you dont have any valuable information on it. This always solved the problem for me.

I formattet the 8gb in mac to mac osx journaled extended I think and it STILL didn't show up in my computer, just in dsk management...
post #10 of 13
Ohh..there's your issue. IIRC windows cannot read/write to a OSX extended formatted drive without a third party driver. Similar to how Mac can read NTFS drives but not write to them.
I'm not sure if you can get the necessary driver for free. I'll check a bit later to see.
