Question about External Drives

3 Answers

PEn drive Hello! I hope you can help me with a problem with my pen drive. All the folders, with the excpetion of one, and all folders in the pen appear now in the explorer with "new" names, random series of letters, numbers and symbols. Passing the mouse over the folders, message appears that the folder is empty; double clicking on the folders gives error messages, not allowing to open folders. However the memory of pen is occupied almost full. Are my files and folders lost permanently? Is it a virus? Is there hope of recovery? HELP!!! I have important data on the pen... Thank you for any help given.

Re: PEn drive

If there are unknown folders, then there are two chances: either FAT is gone or there is some virus. You can attempt to fix it using chkdsk from the command prompt. Force the chkdsk to repair the disk.

Re: PEn drive

You have damaged the file allocation table on the drive. You may be able to recover a little of the data. There are a couple of utilities you can use to attempt to recover data from the drive:

One is ZAR Recovery. It is a trial version that only allows you to recover a few folders at a time but give it a shot:

The other is called PC Inspector:

They may be able to get some of your data back, chances are you may be able to get the data back, but the file names will all be unknown, so perhaps you can figure out what file was what based on its contents when these program recover the data.

Write protection error in pen drive

Hi, It seems to be a virus problem. Install a latest antivirus and scan the pen drive through it.

Virus would not allow you to erase its contents.

I hope this information allows you to resolve this issue.

I have problem with my pendrive

First try to see is there any lock in your usb pen drive and see if its not locking the pen drive, because some pen drives comes with that option to protect usb .it looks like slide switch .for one end it will lock the media and when you switch to other side you have the full access
but if that's not the reason it might be the problem with registry

Use the Registry Hack to Disable Writing to USB Drives
Here is the link .just download the zip folder and after opening the folder you will find a file just double click on it..

Pendrive write protection removing

Hey, the transcend pen drives usually have a small switch on the side of it, ie to turn the write protect on and off, usually a small lock symbol on it, the problem with unreadable files names etc, could be a corrupt partition, i would suggest formatting the drive as long as you aint got any important information on it,

All the best
