Storage Solutions USB pendrive error: Disk is write protected. Unable to format.

nRiTeCh · Jul 24, 2015

Yesterday plugged in my 8g pendrive on friends infected laptop for copying songs from his laptop and during the copying process it started giving error about some write protect.

Now pen drive isnt getting formatted. Tried on win 7 and xp.

Tried HP formatting tool but no ways.

Disk is write protected. Unable to format.

Tried both Fat32 and exfat but same error.

*1. Open Start Menu

*2. Run, type regedit and press Enter; this will open the registry editor

*3. Navigate to the following path:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies*

4. Double click the key WriteProtect in the right pane and set the value to 0 In the Value Data Box. Press OK

*5. Exit Registry

*6. Restart your computer and re-connect your USB pen drive on your computer.

Same issue persists.

1. open command prompt (cmd.exe)
2. type "diskpart"
3. type "list disk"
4. identify which one is your USB disk.

5. type "SELECT DISK n", where n is the number of your USB disk.
*** BE CAREFUL AT THIS PART. Selecting the wrong disk might delete your hard drives ****

6. type "clean", (you may need to repeat twice or thrice). If it doesn't work, don't proceed with the next instruction :-(
7. type "create partition primary"
8. type "select partition"
9. type "active"
10. type "format fs=ntfs"

..but at step 6 the pendrive light goes off and nothing happens further even waited for 2 hrs.

This again same issue persists.

So what is the other way out to fix this very annoying irritating issue????

please check with Chip Genius Software( latest one) to determine the chip inside and go to their respective website to fix the problem. some companies provide online repair too if there is a firmware issue. I bought a HP V165W4GBPendrive from Homeshop18 which dramatically became USBESTFlash2Storage from HPV165W while I was transferring some data from my Desktop one day :arghh:

since it was under warranty I've called up the HP Customer care and may be due to Geographical location, somebody from Kolkata picked up my phone and asked my email address to send me a repairing software but, I've been sent a Jet flash repairing Software in stead

which say, "no Jetflash drive detected! There are some fake HP pendrives on Indian market with firmware tweaked to show 8GB or more on windows only which are acually not(hardly128mb or so). Chip Genius Software can detect it's chip and firmware used and we can fix if it is only a firmware issue and not physical damage like, internal burned out or breakage of circuit etc.

I would suggest to use HDD Format tool - http://hddguru.com/software/HDD-LLF-Low-Level-Format-Tool/

If unable to fix or gives errors during the format - would suggest to replace the drive. Either way, the data on the drive would be corrupt and even if fixable - can happen again.

Well have you tried it on this particular error?

Yes. But it had thrown an error during the format with some sectors, which means that some cells were not readable - thus I threw away the drive.

I tried downloading.

It contains 2 folders one for PNY & Aother for CHIN drives.
SK6226_PDT_20120709_for_PNY_only
SK6226_PDT_20120622_For_China_only

My drives is Transcend ones and didnt got detected in either of those.

Thus this too FAILED!!!

Then, you can give a last try with this installable file size size is around 3.90mb works with most of the transcend drives

URescu

An updte for all. URescue is a very good software for Pendrive with Corrupted firmware usually shows that, "No media found, Insert Disk"
etc. error. I've successfully Cured my HPV165W4GBPendrive which had some firmware issue and showing No Disk/No media. firmware was updated by Urescue and my that drive became useable again
