PostPosted: Sun May 11, 2008 9:47 pm    Post subject: F Drive has disappeared!!!

Hello

Today I was normally downloading some files to my PC from an external hard drive. And sometimes Windows cannot see external drives easily, so I restarted my computer a few times. Suddenly, I shocked to see that my F hard drive has disappeared. It's just not there!!!

What can I do? I cannot see it Disk Management, either!.. How can I solve this problem and use my F drive?

Since you mentioned disk manager, I'm assuming you know how to do this...

Go into device manager & see if you have any problems with the USB stuff. USB is one of those things that works great when it works but can be a pain when it doesn't, & has a tendency to act up at times.

Let us know what you find...

I immediately disconnected the USB after having this problem. So there's no USB connection right now on my computer.

Edit: I forget to mention in my first post, F is not my external hard drive.

1st - wouldn't matter, the device manager will still show root USB hubs, controllers & such.
Given your response, I'll go into how to get to the device manager;
1) Right click on "my computer"
2) click on the hardware tab
3) chooses the device manager button & click on it
4) Scroll to bottom & click on the + beside Universal Serial Bus controllers

If there is anything wrong you probably won't have to do step 4 as this will be already open & there will be a symbol there of some sort.

I only add this 'cause you said you were having trouble recognizing the external drive at times - this could be related.

2nd - if "F" isn't your external drive then please give the drive letter assignment arrangement. - The more details like this you can provide about your problem the easier it will be to troubleshoot.

All USB connections seems alright, I checked every single line's properties under "Device Manager/Universal Serial Bus Controller" and the computer says all of them are 'working well'. Is there any more information I should write about USB?..

Sorry for any misunderstandings I caused, simply: I have C, D and F on my PC. F has disappeared and my external hard drive was using G and H letters... And I was downloading some files from an external 2.5 SATA hard drive and as I said re-started computer a few times just before F disappeared.

I really can't remember anything else that important, but I can answer if there's anything you should know about USB connections or my computer...

Edit: The problem I had with external hard drive is more likely(of course my opinion) because of enclosure or hard drive's connection pins... 'Cause, it was working well with another hard drive, oh well, 'working well' means after re-starting computer, it could be able to see the hard drive.

OK - will let the USB thing go for now - you mention SATA, where there ANY of those +'s in device manager expanded? If not, we'll move on.

So, when you list out your drives, all you see are C & D?
Is the following correct? if not correct it.

C - main boot drive
D - slave drive - (backup or storage)
F - another like D

G & H - external

Do you have any DVD or CD drives? Is one of these letters it?

Sorry, I guess I'm dumb today, what's "+s" mean? I'll answer once I understand what is that plus sign.

You are correct about C and F is Primary Slave. Detailed:

A (no mention, you already know)
C=FAT32
D=FAT32
E=DVD-RAM
F=NTFS

I don't write capacities, probably not important. Besides, I don't know if it does mean anything, but BIOS screen shows F still as my primary slave.

The plus signs are at the left of the list in little boxes when the contents are collapsed & minus sign when expanded.

The "?" in the picture are one of the signs of trouble I was referring to. If all is well it will all be collapsed as in this picture.



Why do you have "F" NTFS & your boot drive (I think you said is C) FAT32?

As I already said all of them are working fine.

And C is my boot drive. F is just for my files, there's no system file etc.

Saying "all of them" I referred USB, but there seems a problem with SCSI/RAID.

Just to make sure - rule out - have you rebooted since you posted this problem? If not, try that & see if it comes back. - it is a good sign that the BIOS is seeing it so we will have to figure out why the OS isn't.

Also, do you know how these drives are actually connected in the box? - Which drives are connected to what controller? You mention F being slave, what are the others?

I restarted computer a few times to see if it'll work. The latest was between my previous answers, and it was the time I saw F as primary slave. But I'll try once more...

C and D came when we bought this computer, but F was added about one year ago.

BIOS sees only two HDDs, C and D must be the same. Because second HDD is exactly have the same capacity as F. And C+D=the first HDD.

Don't know if there's anything I forgot to write...

Note: About F being NTFS, my answer was for "what is your BOOT DRIVE?". For "why?", I'd say "ask the technician". : )

OK - here is what I see as your hookup:

controller A - Primary drive, 2 partitions (C & D)
controller A - Secondary Drive, 1 partition (F)

Controller B - Optical Drive primary

But since you mentioned SATA could be a bit different but unless you know for sure I'll go with this.


I take it this is a tower & not a notebook, so can you (with computer unplugged) check to make sure that all the hard drive cables are secure - especially F? (touch the case to ground yourself first as to not static fry anything inside) - If you never done this before & don't feel comfortable doing it, is there someone that can do it for you?

The 2.5 SATA I mentioned was my external hard drive removed from laptop, just for record. I checked BIOS again, and C(20GB) and D(20GB) are Primary Master(40GB). F is Primary Slave.

It's PC and I unpacked it many times, no problem, but I guess I'll have to do it tomorrow, 'cause it's midnight here.

How can I understand if they're connected correctly or not?.. Will I just tighten the cables?

Yes, just make sure they are plugged in tight. (for now)

Another thing to check is your event viewer & tell me if there is anything in there about drive problems. Copy & paste what it says.

To get to event viewer;
click start
click control panel
click administrative tools
click event viewer

In the right pane double click on system & look for any warnings or errors.
Double click on these for more details. - check apps, too.

BTW: when was the last you or anyone else was inside? What was done? - If real dusty may want to clean in there, too. (can of air for computers works good)

My Windows is not English, I'll have to translate some errors...

OK - since not english, just type out the translation the best you can.
Also, I assumed you are using XP, is that the case? - I should have asked before when I was telling you how to get to things. My bad, & sorry if it caused any confusion.

At this point I'm doing a little research to make sure on things so may be later tomorrow (Monday) before I get back to this.

These two things still need addressing:

What problems with the SCSI/RAID are you referring to?

AND...

Quote:
...but F was added about one year ago.


There is still a possibility that the drive may be going bad. The event viewer SHOULD tell this, though.

These ARE IDE HD's were are dealing with, right?

Is "F" showing up in device manager under disk drives? It will be listed as to the maker not the drive letter.

I can't write the details, but F is working now. The problem is, the computer re-starts itself after a few minutes it turns on...

Last time BIOS screen appeared and in red:

"During the last boot-up your system hung for improper frequency combination. Your system is now working in safe mode. To optimize the system performance and reliability, make sure the frequency combination conforms to the specifications of your CPU, DIMM and other connected devices."

What can I do?
