F:\ inaccessible. Parameter is incorrect. Desperate, Please Help! Thanks!

Hi all,

I received this error msg, "F:\ drive is inaccessible. Parameter is incorrect." after I restarted my computer. I had no problems with it before the restart, and I didn't restart my computer by hard/soft reboot. I just clicked on the start button from start menu and chose shutdown>restart from the popup window.

I have only 1 40gb harddisk (IBM), and I've partitioned it into 4 drives, C, D, E, F. I can still see the F drive there in My Computer, but i just can't access it.  I don't see F drive as an option, when I try to do drive scans.  F drives contains all my important stuff, so I hope I can access it again without losing any of the files.  

Thanks for your kind attention.  I really look forward to hearing from you all soon. ><

I Would so as Crash advises however I would do it from the Recovery Console. Once the console loads run this command.


and it will identify every partition and drives on you system inclueing the CD and Floppy drives.

You do the MAP command to find what letter the Recovery Console has given the partition in question. and do

chkdks TheDrive: /r

To start the Windows Recovery Console, use any of the following methods:
Start your computer by using the Windows Setup floppy disks or the Windows CD-ROM. At the "Welcome to Setup" screen, press F10 or press R to repair, and start the Windows Recovery Console.

Crazy2100, Crazy One, thanks very much for replying.

I had tried running chkdisk from command pronpt in windows, and the chkdsk failed. I got a popup window saying the checkdisk has encounterd a problem and needs to close. I guess it can't find my F drive, therefore unable to do a scan.

As for crazyone's solution, I don't know where and when to run the MAP command. After the console finishes loading, there are 3 options, 1) run windows installation; 2)recovery console; 3) exit and restart. I chose the 2nd one, and I came to the part which requires me to type in the adminstrator password. And for some stupid reason, I didn't key in an administrator password during the installation, and the windows installed without one. Since I had no administrator password, it forced me to quit and restart.

So, what else can I do now? T-T Also, do you know what caused this? Very likely a harddisk failure? Coz I got the bootdisk failure some weeks ago too. Well, I just hope to get access to the hard drive to at least backup my stuff ><

p.s. The drive I have the problem with, contains only some picture files, zips, programs installation files. I didn't install my windows, nor any programs in that drive.

Once again, THANKS VERY MUCH~ I really need your help ><

Also, I'm getting the ---- ---- sound from the harddisk, after I've gotten this "F:\ inaccessible" error. Is it possible for me to recover my data with those data-recovering software (especially when I can't even access the drive), and how?

Thanks T-T

Thanks for the links. :D At the end, I used the GetDataBack, and was able to recovery most of my data. I still couldn't run scan/check disk on my F:\ drive, I guess I will try to send the harddrive back for warranty service.  Thanks a lot for your help. :D
