Can't access data on my usb mass storage [Solved/Closed]

Try to run "chckdsk x: /f", without the quotemarks and where x is the drive. I think you have to do it in Safe Mode MSdos [restart, press F8, go for "safe-mode with command prompt"], or when in XP mode: right-click on drive X, open Properties, Tools-tab, click "check now". You'll get message is not possible, only after restart: it will be scheduled at next reboot - just reboot.

If your disk is just too old, funked-up, or qurwalized and you just want to try to save the data, then please do use special software (or some PC-freak near u) - don't let XP try to fix it! For

usb device detecting and ready to use msg comming while pulg in in usb port but not drive shown in my computer

This is Kumar Pushkar from Bangalore India; even my seagate usb hard disk was not detecting error was something like all data has been corrupted cant detect even the segate disk manager was useless ,but friends there is one solution that worked for me just goto command prompt type chkdsk G:/f G:-is my usb drive just check it whether its useful for you.

Do NOT format the disk - That will make it much much harder to recover the data.

I think you have a MBR (master boot record) problem - there is a fix.

Google MbrFix - download the program - burn it to a CD - boot from the CD (you might need to change the boot order in the BIOS to boot from the CD)

fix the MBR on drive 2 your E drive (((( NOT on drive 0 which is your C drive))))

Dear Friend,
A few days back, I had installed a software called as 'USB Immunizer' but it started giving other troubles and hence I uninstalled it. Since then, I am not able to open any of my 3 USBs. They contain about 30 topics written by me on various subjects.
With love,

I have this same problem easily solved heres what to do this worked for me:

load up in safe mode (tap f8 on boot up) choose normal safe mode (rather than with command prompt or networking)

if asked load in as administrator

once loaded in locate problematic drive in my computer (double click on it and it should open)

next go back to my computer and right click on drive selecting properties

goto security tab and click on advanced to change permissions

then click on owner followed by edit

you should have a check box on the bottom of the screen to replace owner on subcontainers and folders tick it and click ok

all subfolders will be reset to you as owner and will be able to open it I believe this to be a problem with vista and on.

hope this helps someone :)

Partition Wizard Home Edition SAVED MY EXTERNAL HARD DRIVE YEAHHHHHH

lol

Recover your files by downloading and running file scavenger 3.2, really simple to use, I got it from here: http://inspirez.net/

If like me you accidentally deleted/corrupted partition table or boot sector of the flash drive, its probably still alright. My 8GB Integral drive is 3 weeks old so I'm so glad I found the next page!

To make your flah drive usable again, first perform a Low Level Format using the HDD Low Level Format Tool from here: http://hddguru.com/content/en/software/2006.04.12-HDD-Low-Level-Format-Tool/

Again easy to follow, after it finishes perfom a High Level format (not quick) and its done, great! :D

Hope it help some other people

if i connect my pen drive in computer(windows xp) then i can't access my data and can't formate my pen drive by right click options.

thanks for the help xpcman- I see that the Mbrfix program is for advanced users, unfortunately i am not quite advanced enough, so to bother you with another question.. did you mean I should run the command "MbrFix /drive <num> fixmbr Update MBR code to W2K/XP/2003" in the Mbrfix program (on drive 2)?

I'm on the same boat, I have a 500GB comstar external drive. I was in the middle of a chkdsk with the drive & the power at my house turned off, my laptop was fine but my external drive loss power (obviously) so now when i access the drive in windows, the name of the external drive change (looks like the default name) & I can't see any of my files. But it shows there's still data on that drive.

I tried redoing the chkdsk /f /r & other data file recovery programs & no dice. I couldn't fix the fdisk /mbr using command in windows, it gave me an error saying that it couldn't find fdisk or the command was valid (can't quite remember the exact error)

ANYONE HAVE SOME IDEAS?!?!?!
Thanks

It's there but how can I get my data. Its important business related data.

i have a wd external usb hdd 250gb, my computer gave a blue screen while moving information from my computer on the external. After the bluescreen i had to reinstall the operating sistem and after that it said that the hdd data is undreadable or corrupt (on winxp). i also have a laptop with windows 7 and when i plugged the external hdd on the laptop it said it had to format it in order to access. so i tried various software, i have dealt with this sort of problem in the past and used data recovery software with great success. however this time it would only see part of the data, not all of it (after a deep scan, not a quick scan), and most of it could not be used. for example i had about 10gb of personal stuff (pictures, pdf, word, etc) in a folder, i managed to save it back in my desktop but not a single file was usable. the pictures couldn`t be viewed, the music and the videos couldn`t be opened, same for the other files. so basicly 10gb of junk, the files did have the exact size as the ones in the past, just unable to be opened.

i read many forums on this issue and tried the partition magic method. needless to say it came to no result, so i played a bit and found the "fix partition system" option. i didn`t know that fixing would result in deleting files (it started "deleting orphan files" with various numbers following). So i closed the process with task manager and tried accessing the hdd again. this time it worked without prompting for format, and there was some data on it (the data that i had previously recovered using data recovery software) and the rest was no more.

now i`m convinced that maybe an expert could have saved the rest of my +50gb of data that have been lost, but by my own strenght using free software found on the web (such as active undelete, get data back, etc.) i don`t think it would have worked either way.

now i think it`s 2 late, but i`m thinking that if you can recover data after a format, i might have a chance of salvaging something and i`m pursuing this further (but with very little chance of victory). i`ll update if i manage to save something.

Ive looked through all the answers and none of them worked for me, my 1tb HDD decided it wanted to be formated and i couldnt get any of my files off it.

Finally I found some freeware that is able to locate either deleted files or access this cuntish HDD.

Trust me on this one its works. Just go into options and tick the wee box that says scan undeleted files or something.

Hope that helps, because I found it torture trying to get my files back.
