Thank you so much

[@nikhilvas5817]

Worked for me man

[@shreevlogs8217]

It did not work help me out if possible. It shows that no usable free extent could be found. It may be that thre is insufficient free space to create partition at the specified size and offset. Asking to specify different size and offset values

[@jasonsteves734]

Thank you!!! you fixed my USB

[@ArduinoTeen]

I installed ventoy in my Android phone and format my pendrive and it's working

[@alexkotsovos6800]

Literally tried everything but my sd refused to format. This is the ONLY solution that worked. Thanks mate

[@bobmiller3984]

DISKPART> create partition primary No usable free extent could be found. It may be t free space to create a partition at the specified different size and offset values or don't specify maximum sized partition. It may be that the disk sk partitioning format and the disk contains either more partitions may be created), or 3 primary par partition, (only logical drives may be created).

[@vesmachartiste3152]

This is the result when i try to create partition. "DiskPart has encountered an error: Data error (cyclic redundancy check). See the System Event Log for more information." what should i do next? is there another way to fix my micro SD?

[@UCmDBecUtbSafffpMEN3iscA]

Encountered the same thing here

[@TheWael1996]

[@osceyconVR]

you could try using third party software like AOMEI Partition Assistant or something

[@benvarela134]

Good video. Well done... I've been at computing for 27 years and I'm still learning every day. Thanks, Bob.

[@Britec09]

No one knows everything, we all learn from each other every day.

[@notdzul]

[@boblegogamer]

@@silarmohammedtanwir2897 just delete the partions

[@techexpedition]

Creating new volume solved my problem, Thank you 😀 +1 like 👍🏻

[@CesareVesdani]

It happened to me once where I purchased a new USB drive and it worked fine. After reformatting the drives a few times, it got corrupt and it was impossible to reformat the drive again. I had to bring it back to the shop and get a new USB drive in its place.

[@robpet4424]

Come on all you viewers who haven't suscribed..... we need to push suscribers to 500,000 ! Too good of a channel not to. I've learned so much from Brian's videos. Thanks !

[@Britec09]

Glad it worked out.

[@erikpauls80]

Thank you!! At 2:40 my USB was back in action. My USB was working fine until I formatted it through command prompt with select disk and clean. The information you provided solved a potential disaster lol.

[@muzbar2]

Amazing tutorial, it helped me out greatly. Thank you so much.

[@MADREZA]

4:24 after create partition primary this error comes up DiskPart has encountered an error: The request could not be performed because of an I/O device error. See the System Event Log for more information.

[@СтилианБашев-ц6х]

After the "create partition primary" i can't see my device in This PC

[@TheWhiteTiger1]

go to manager and make drive in disk manager

[@bagassetiaajiesutikno9945]

Didn't work for me. Diskpart has encountered error: the system cannot find the file specified. How can i fix this?

[@arzee09]

after create partition in cmd diskpart---> it says device is not ready, see the system event log for more information

[@ThinkPositiveDude]

This works, thank you!!! just a quick note though when I closed out the command prompt part, it still showed the wrong capacity, so what I did was I ejected the flash drive and reinstalled it prompting me to format the drive which showed the correct size.

[@tazgma311]

thank you . I had issue with my 32gb flash drive now it fix

[@vesmachartiste3152]

And also this error appears when i try to fix my flashdrive. "No usable free extent could be found. It may be that 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. It may be that the disk is partitioned using the MBR disk partitioning format and the disk contains either 4 primary partitions, (no more partitions may be created), or 3 primary partitions and one extended partition, (only logical drives may be created)." is there also a way to fix this? can u please help me... thanks

[@hafiezjamali8518]

thank you very much for sharing this

[@oneszeros1]

Nice video Brian - frustrating also when flashing Linux images to USB but trusty ole diskpart can always fix the issue with a couple more commands I.e., list partition - > select partition x - > format fs=fat32 (think I remembered that correctly of the top of my head!) - cheers mate 👍

[@Britec09]

Diskpart is very powerful

[@billytv1734]

Thank you so much! I have been having this issue for a very long time

[@remixedMind]

minitool partition wizard is also very handy

[@Britec09]

Yeah that works also.

Tip 2 dont buy chinese usb drive fakes on ebay.

[@anynomoussucker823]

Bought 2 chinese flash drives, lasted for 2 years fortunately

[@mmortal03]

Whenever I've "DD"ed a Debian ISO to a thumb drive like you're supposed to, and then I've later wanted to wipe the drive on a Windows computer, I've gone into diskpart, selected the thumb drive as the disk, ran the "clean" command, and then *boom*, I'd run into this problem with "unknown capacity". It looks like I'll just need to remember to "create partition primary" while I'm still in diskpart, and then everything will be good.

[@e.acmputerrepair525]

Can please make video if the usb have date and windows can’t not Recognize it. Thank you for hard work of taking your time showing use this that big help.

[@Britec09]

You mean drive not recognized?

[@e.acmputerrepair525]

Britec09 yes sorry for my Spelling.

[@Britec09]

No need to apologise, I see if I can make a video.

[@amcheck4828]

[@IAM_KSR]

didnt work

[@SuperLittleTyke]

EDIT: SEE FIX ABOVE! On a USB 32GB Samsung micro SDcard with this problem I get an error performing DISKPART. As soon as I type in create partition primary and hit Enter I get: "DiskPart has encountered an error: The request could not be performed because of an I/O device error. See the System Event Log for more information." Note: I can insert a different USB stick or micro SDcard into the same USB port and it reads/writes okay.

[@ExcelClasses1]

It worked for me perfectly. Thanks a lot for saving me a few bucks atleast. I was thinking of buying a new one. A big thumps up.

[@SuperLittleTyke]

I've found that the I/O error mentioned in my first post in this comment thread was caused by a faulty SD Card adapter. I have been using the Integral Dual-Slot Micro SD & SD USB2.0 Memory Card Reader Adapter (white one shaped like a USB stick) for six years. Instead, I placed the unreadable/unwriteable micro SD card in a different adapter (one with a USB cable attached) and Windows 10 recognised it instantly. I ran error checking on it and Windows found and corrected a few problems, but everything is working fine now. Four days I've spent on this, watching KZbin videos and searching Google! So the old Integral adapter is going in the bin, along with a duplicate, which is even older.

[@harikrishnanrk977]

Can you help me? USB showing as RAW(Disk Management) and can't find the file specified message appears every time when I try anything. Create Partition Primary stuck. Virtual Disk Service Error. 2nd time it showed There is not usable space for this operation. Available only 1024 KB (32GB pendrive). Problem occurred when I tried to reformat with Rufus to change Windows ISO.

[@sadanand14]

Doesn't work on win 11on My pen drive with identical defect. The laptop runs into error and restarts when either CLEAN or CLEAN PARTITION PRIMARY is entered.

Hi, i do follow your step on cmd with create partition primary, and it pop out this error message "DiskPart has encountered an error: Data error (cyclic redundancy check). See the System Event Log for more information." not sure you have any idea of this?

[@mattheadlee7683]

Please help. Keep getting Data Error: Cyclic redundancy check - ??? at end of "new simple volume" any help tremendously appreciated

[@arttu201]

No usable free extent could be found. It may be that 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. It may be that the disk is partitioned using the MBR disk partitioning format and the disk contains either 4 primary partitions, (no more partitions may be created), or 3 primary partitions and one extended partition, (only logical drives may be created) any idea ?

[@Bala-nc4sn]

Brother, thanks you so much. You saved my day with your tutorial. I succeeded in getting my usb disk back.
