Ilya Verbitskiy Thoughts and links about computer programming

Today I played with the latest SUSE Linux Live. I had not have a DVD drive and used USB flash drive instead. I wanted to reformat my flash drive, but suddenly found it that it had not been possible. The most of the disk space had been unallocated, and my Windows 8 did not allow me to use it.

Unallocated

Unfortunately Windows does not support Fdisk anymore. But there is another good command line tool to solve this problem. The tool’s name is DiskPart. I would say it is the next generation of Fdisk tool. DiskPart provides you information about your partitions and volumes, allows you to delete and create partitions, extend NTFS volumes, etc.

Let’s remove unallocated space. First of all run Windows command line and type diskpart in the command prompt. Windows will ask you for Administrator permissions to run the tool. Then run list disk command to find your USB flash disk’s number. It should be the same as disk’s number in Computer Management tool. It was 1 in my case. Next you should chose the disk to work with. Type select disk <disk number> command, e.g. select disk 1. The next step is to clean all volumes and partitions on the disk. Use clean command to do that. The last step is to create a primary partition. You can do that using create partition primary command. That’s all. You should be able to format your flash disk now.

This is how I removed unallocated space on my machine:

Microsoft DiskPart version 6.2.9200

Copyright (C) 1999-2012 Microsoft Corporation.
On computer: COMPUTER

DISKPART> list disk

  Disk ###  Status         Size     Free     Dyn  Gpt
  --------  -------------  -------  -------  ---  ---
  Disk 0    Online          298 GB      0 B
  Disk 1    Online         7509 MB  6619 MB

DISKPART> select disk 1

Disk 1 is now the selected disk.

DISKPART> clean

DiskPart succeeded in cleaning the disk.

DISKPART> create partition primary

DiskPart succeeded in creating the specified partition.

DISKPART> exit

Hi, im extremely fed up of my pen drive, please help.It is 16gb strontium usb and runs on every computer except this brand new hp probook which i am cirrently using.
In disk management,it shows the entire 14.6gb is UNALLOCATED.
I followed the above steps, selected the disk, but after that when i try to clean it, it gives an error:"Diskpart has encountered an error: The system cannot find the file specified. See the system event log for more information."

Ive tried reasigning the disk to K, D, I Z S, nothing works. I formatted it from NTFS to FAT32(using other computer), still exactly same problem. Ive uninstalled and installed the driver multiple times,

Please help,i'm at my wit's end.
Thanks

Hi,

You may try to use Lexer Tool. See the post http://totseans.com/bbs/threads/7483-Lexar-USB-format-tool. If it still shows you the error, then check your event log and try to find what is wrong there. I think the error message should be in Application or System log.

You could try to use diskpart on another computer. There is a little chance you have a problem with yours. Otherwise I do not know how to help you. Sorry. It might be a hardware issue with your pen-drive.

WOW, just used this on a 32gb flash that I got not too long ago and it worked AMAZING! The first time that I used the "Clean" command, it came up with an error saying that Access was denied, but then I literally tried again and it worked just fine, which in the computer world.... is just damn odd. Weird. Still, thanks for recovering my lost 26GB!

Thanks. Sometimes software makers think we all have a degree in computer science. I've downloaded a Raspian image for a Raspberry Pi I just purchased, Followed all there instructions to the letter which included the software tools they recomended win32 disk imager & sd formatter & all I seemed to do was stuff up the sd card. Thankfully you helped me with that one. Much appreciated.

I'd try to remove the USB, then plug it again and see what will happen. If you still have the problem, then try different USB port. If it won't help then there might be a problem with your USB drive. Try another PC because it might be a problem with your USB controller as well.

If computer does not detect the drive automatically please follow the procedure (Windows-7)
right click the 'computer' click 'manage' select 'Disk Management' than identify the disk (IMPORTANT), it will not be having any name I identified it by size and the 'file system = raw' (DO NOT pick 'system reserved' or 'recovery partition', right click for formatting , give name to 'volume lable', again right click on the same drive 'change drive letters and path...', 'Add' assign the drive letter by picking AND YOU CAN SEE THE DRIVE !!!...

Hi!

My brother has managed somehow to lost all GB from my USB flash ( I have JetFlash Transcend 8Gb and now it shows only 383MB )... I did all you said to do, but in the first step, i got next information:
Disk ### Status Size Free Dyn Gpt
-------- ------------- ------- ------- --- ---
Disk 0 Online 298 GB 0 B
Disk 1 Online 7683 MB 0 MB

I did all you said to do, but then in the last step, I got next information:

"There is insufficient free space to create a partition at the specified size and offset.
Specify different size and offset values or don't specify either to create the maximum sized partition."

Can you help me, please?
Thanks

# Recover Hidden Files From Flash Drives or External Hard Disks Due to Virus Infection
Requesting Gravatar...
If the files and folders in your external hard disk or flash drive have turned into shortcuts or are hidden, here is one solution to recover your data. Operating system used – Windows 7.

Install good antivirus and scan entire computer including the flash drive/external hard disk.
Go to Control Panel, Folder Options, select VIEW tab, select ”Show hidden files, folders and drives” and uncheck ”Hide protected operating system files (recommended)” now click APPLY

Open command prompt (press Win+R, type cmd, press enter), assuming ‘G:‘ as the letter of affected drive, enter this command-

attrib -h -r -s /s /d g:\*.*

replace ‘g:’ with other drive letter if needed.

You can check your flash drive/external hard disk, the data should be visible. You can restore the original folder options

Thanks a lot. Worked perfectly. Oh, but 'create primary partition' brought up options rather than just saying 'done'. So I did that bit via disk manager:
right click on My Computer, choose Management, then click Disk Management, then right click next to USB stick and Create New Volume.

hi
plz i have a 500 Gb external HDD but it is partitioned with a security key card. when you pass the key on the security side then the whole 500GB opens. unfortunately for me the external hard drive fell off the table and the key stopped working. i called were i bought it and they told me to buy a new case which i did but the other part of the HDD those not appear i only see it at device manager.
because there are a lot of things i have on it so i told them to help me get it back but all they could tell me was that they gotta format that part before i can access it. so plz what can i do so dat i dont loose any document and file. plz recovered fills always baffle me because of the renaming of files in different folders which makes me loose a lot so plz i need help.
What should i do?? .
i even tried working on it but each time i slot in the external hard drive it asks me to format but i dont want to loose anything so i haven't formatted it yet.

If you want to recover data from unallocated space, first you have to make sure you have not overwritten the unallocated partition

Follow this tuotiral to do it:
