F:\ is not accessible

December 11, 2010 at 15:25:12
Specs: Windows 7
Okay so here is my situation

I plugged in a SD card (512 mb) that came with a karaoke machine into my computers card reader and then it said.

"You need to format the disk in drive F:\ before you can use it"

And i thought it was just a read only sd card so i unplugged it and plugged in my dslrs memory card and then it showed the same error!

I do not know what happened at all and i tried to format it and all i get is a box saying

"Windows was unable to complete th e format"

I also tried to remove its drive letter and put in another drive letter and it still doesnt work.

Does anyone know a solution for this problem i am having?

If it helps my computer is an hp pavilion elite hpe running windows 7 with 8 gigs of ram and 1 tb of memory.

Some USB sticks have a tiny read only switch usually on the side. This may have been accidentally set to read only. Change it back if that is the case.

The other possibility is that it has somehow been damaged.

The lock slider on my sd card is not on lock and i tried putting in 3 other sd cards into my card reader and the "You need to format the disk in drive F:\ before you can use it" pops up again. I'm kinda scared cause i have a lot of valuable footage that i cannot lose.

A few thoughts and ideas:

It could be your SD card reader.

However, you said one of the SD cards did not work in your dslr either. Is this true of the other SD cards?

Is there also a possibility that by putting your SD cards in the SD card reader it has damaged the SD cards in such a way that they can now not be read in your dslr either?

Are the contacts on the SD Card clean?

What about the contacts on the SD card reader?

You could try blowing away any fluff that might be in there?

You could also try re-booting your PC. This helps sometimes if the software and/or drivers have got their knickers in a twist.

No, the SD cards do work in my dslr they just dont work when i put them into my sd card reader.

Yes, the card and contacts on the sd card reader are clean.

Is there any way to avoid reformatting the sd cards??

Formatting (subsequent to the first time it is formatted) is normally used as a quick way of deleting the contents of the SD card.

If the cards work in your dslr and you can see the contents then why would you want to format? Is it so that you can reuse them?

If you want to reuse the cards and If your camera has a bulk delete facility you can use it to empty the card, then format would not be necessary.

If you dslr does not have bulk delete capability then you would have to delete each photo individually in which case it would take you a long time to empty your card for reuse.

In any case you are saying that attempts to format using your card reader is unsuccessful so you cannot do it that way.

The current state of your card reader also means you cannot use it to transfer files to you PC through it.

If indeed your card reader is damaged, then you can buy external USB based card readers which do not cost a fortune. That is probably the best option as you need a quick way to empty your cards for reuse.

Incidentally when you are formatting your card using the card reader what file type are you selecting? Is it FAT, FAT32 or NTFS.

The reason for asking is that most cards need to be formatted using FAT or FAT32.

If that is the case it may be that you are trying to format using NTFS and it does not like that.

I think this may be what the problem is. Am I right? If I am, try formatting it using FAT or FAT32.

Don't format if they have data, Did you try it in another computer? The card reader or software could be bad.

@mosaddique Well.. when i go to disk management, the file system says "RAW" not FAT or FAT32 or NTFS. And i have tried to format one of my SD cards with info i dont really need and it just says "The format did not complete succesfully"

@wizard-fred Yes i have tried it on 2 different computers and they work perfectly fine. So im guessing its the card reader here. Do you have any suggestions towards fixing the card reader? Or could it be the disk driver?

Sounds like it is the card reader that is faulty.

As these generally do not have moving parts, the only possibility would be bad contacts or something wrong with its circuitry or cabling.

You could check the cable that connects it to the motherboard to see if it is intact and you could also check its power feed.

Both require you to open up your PC.

If there is a driver for it then you could try installing/refreshing it and see what happens.

Otherwise replace it.

"Some USB sticks have a tiny read only switch usually on the side. This may have been accidentally set to read only."

In that case, if there is nothing else wrong, you should have no problem reading the memory card, even if you can't format it.

"The lock slider on my sd card is not on lock and i tried putting in 3 other sd cards into my card reader and the "You need to format the disk in drive F:\ before you can use it" pops up again. I'm kinda scared cause i have a lot of valuable footage that i cannot lose."

"i have tried it on 2 different computers and they work perfectly fine. So im guessing its the card reader here."

If the card reader is removable
- try it on the other computers.

- you may need to plug it into a different USB port on your computer, or use a different USB cable with it.

Rarely, not all the ports on the back of a desktop case may be able to supply 500ma each.

If you have a desktop computer, Note that I answered a Topic on this site recently where a guy had an external drive, which does require the full 500ma, connected to a port on the back of a desktop case - it would not work properly when a webcam was in the port next to it, but it worked fine when the webcam was unplugged. Ports on the back of a desktop case often have two ports connected to the same USB controller module that are ports one above the other - you could try connecting the cable to one of those and leaving the other un-used.
