Hi Guys and Gals of the forum

I need some help.

My son has all his college stuff on the pen and when we plug it in we get this error message.

H:\ is not accessible.

Whatever you do, do not do anything that will cause a write action upon that pen drive until after the folders and files have been successfully copied off of that pen drive and onto an SSD or platter-driven hard-drive.

 

[RolandJS]

Upon what computer or computers is the pen drive used on mostly? I ask because sometimes computer B will misread or not read a usb media device in which material was placed upon it by computer A. That just happened to me today; I'm bringing back my two cheap usb flash drives for that very reason.

 

[RolandJS]

Completely shut down computer A and/or computer B. Insert the flash drive into a known-good working usb port, power up. Wait until desktop is completely at "parade rest." Use explorer.exe [what we used to call File Manager] to determine if the flash drive can be seen, and be read. If it is seen and can be read -- copy, not move, everything off of that flash drive onto any known good SSD or platter-driven hard-drive.

Thanks RolandJS

I appreciate your prompt replies.

Pen has been always used in system A and system B Ho does not have a printer so most weekends he brings the pen home and uses a system at home to review and print

Have tried the boot on all three systems still the same.

Is this one of those FDE, full data encryption flash drives? I thought I saw a thread or two over in BleepingComputer.com about this. You might want to do some search and read. I normally do NOT suggest cross-posting! However, school stuff is important!
Going forward, please purchase two twin 64GB or 128GB nonFDE, non-Encryption, flash drives from a well-known, well-respected, dedicated business-oriented computer store. It will cost! However, your son's college stuff is much more important than to be entrusted to just one flash drive. Please have him always copy [not move] folders/files onto both flash drives -- and ensure Safely Remove is followed ['cause computers can be very cranky!].

Start > All Programs > Accessories > Commnd Prompt

Against the prompt type chkdsk x: /r and press ENTER Replace x: with the actual drive letter of the pen drive.

Allow check disk to complete and repair any bad sectors. Problem resolved?

And yes, you should always have a backup of important data which you can ill-afford to lose. Train your son to do that.

Hi Jumanji

Thank you for stepping in to the thread to try and help me solve this problem

As per my initial question you can see that I have already tried CHKDSK as you can see below

And yes I have told him umpteen times to make sure he has everything backed up, we have the majority of his stuff back up it's just the last ten days.

 

[jumanji]

Oh! my bad... I didn't see it.

Please wait to see if others can come up with a solution.
