Formating External drive/ sd card issues

Hi. I've been using windows 7 ultimate for more than a year and i never had to format anything with this computer yet and now it seems that I cannot.
I tried to find other threads but I couldn't find an answer to my problem.

FIrst of all, I tried to use an old 8gb Usb flash drive that I didn't use for maybe 6 month. When trying to open the drive from '' my computer'' it told me that I needed to format it. So I tried any possibles ways. ( In disk management, it tells me it's Raw, Healhy, primary partition. I Tried in every type ( fat32, exfat, Ntfs, Normal/quick format) It's always UNABLE to complete formating.

I tried with another type to see if my flash drive was simply Defect by using an old HDD iOmega 320 gb. Same thing happened.

Now, I just bought a brand new 8gb Micro Sd card and I still get the same thing.

I Tried formating with COmmand Prompt and It's still unable to farmat anything.

I decided to try them on my old Laptop working on Vista 32 bit and I only got my Hdd iOmega formated, but still got the same problem with the other 2 flash drive.

If any one could give me a hint of what else I could do, I would be eternaly gratefull T_T'

Hi Semi,

Try the following.

1. Do a drive cleanup as detailed here USB disks not recognized although USB mouse & keyboard are . After that connect your USB drives and try to format.

2. Open Windows Disk Management and view your flash drives/other USB drives. Delete all existing partitions in them. When it shows just one volume, right click on it and format. Do a full format and not the quick format.

3. Download and run HP USB Disk Storage Format Tool as administrator to format your USB drives.

First of all, a Huge thanks to both of you for the incredibly fast reply to my post.

I tried first with the brand new sd card..

I first did both of the SeaTools test ( SHort and long), Passed.

Rufus didn't work.

Then, I did step by step the guide for the disk cleaner and it end up Positivly without any ''error'' or so.

First format ended as usual ( Failed ). I still tried then with your step 3 hoping that it would maybe work!? Didn't.

I'll try later with any other storage device I have. Thanks again, if you have any other idea, I'd be glad to try them
