I have a Jobo Giga One 40 Gb portable disk which I use to store photographs from the CF cards from my Canon DLSR camera while I am away from home. Returning home I will copy all the photos to my PC and erase the files and folders from the JOBO device.
I do this using Windows XP Explorer/File Manager and do this by 'Shift-Delete' so that the files and folders are deleted and NOT saved in a Recycle Bin. So right now Windows tells me the the Jobo disk has over 39 Gb of free space. I have checked that there is nothing in a Recycle bina nd there are no hidden files or folders. BUT the display panel on the JOBO device tells me the I have only 1 GB of free space and if I try to copy a CF card with say 1.5 Gb of data it gives me an 'ERR' message. So my JOBO device is now unusable even though it is completely empty.
How can I get the device to reset the free space so that it correctly shows what is available ?
Hi have a nice day!
Perhaps you have used "fdisk" command to delete-create logical drives, and then format NTFS file system.
Please let me know if this way is applicable
Why don't you try to format your external drive. There's a variety of options where you can format it. The first one is Go to the My Computer then Right Click on the Icon of your External Drive then Select Format, it is better to select full erase of the the drive.
Just follow first my instruction's before you go on to the most complicated one.
See yah!
Format it on Win XP boot disk.
i think you know that part?
THe installation disk of XP can reformat your drive, there's also a FAT32 option type.
FDISK on XP?
Be sure your drive got no "bad sectors"...
Try CHKDSK with the drive letter you wan't to Scan...
Lost clusters are storage units undocumented by the FAT (file allocation table) holding partial files at the end of a chain (a sequence of clusters storing a file on a hard drive). These clusters are lost because the FAT was disrupted, perhaps by a power loss or application crash, before it could fully document the chain.
Windows runs the ScanDisk (Win95/98/Me) or Chkdsk (WinXP) utilities to make sure there are no resulting file errors. ScanDisk and Chkdsk can turn stray pieces of files, or lost clusters, into file fragments for your review. You should review the file fragments Scandisk finds instead of letting it delete them sight unseen. After all, you may be able to rescue parts of some of those file fragments.
Thanks,
See...! i told you, there's many possible ways i can help you.. at first you never believed on what i say to you..
anyway, got your player working, and you never gone up which i say to you the most complicated one of what you think first..
Cheers.

Hello sir
ya sir
its not about resetting the device
its the virus which has changed the file properties and makes it hidden
the virus may belong to rontok bro family of virus which does this job
this can be solved in 2 ways
1>> install a antivirus of enterprise edition and update it for todays update and then check for virus and delete it
2>> else you will have to loose your files and delete everything(format) the whole drive
your option is to use any one of these
thank you sir
good luck
have a good day

Yes ? Can you offer a solution to the problem ?
I doubt your suggested solution.
I have a fully up to date antivirus system installed so there should not be any problem with a virus. Even if there was then it would affect Windows view of the device. Windows shows that there is over 39 GB of free space. I have set the view options for the device to show all hidden and system files and there are none apart from the usual Recycled and System Volume Information.
I have considered reformating the device - there would be nothing to lose because it is empty. But the device as shipped is formatted with a FAT32 file system. If I try to reformat that with Windows XP it says that the device is too big for a FAT32 file system. I do not want to format it with an NTFS file system because I do not know if the JOBO software/firmware is compatible with that.
Any other suggestions ?
I think the proble is with the JOBO firmware/software. It needs to reset its free space counter.
I am well aware of how to format a drive. I have been a PC Systems programmer since the time of DOS3.3 As I have already stated, Windows XP will not let me reformat the drive as a FAT32 file system because it says that the disk is too big for that file system. The problem is not with Windows view of the device it is with the JOBO's view of the state of the device.
Nothing helpful so far.
I have already tried to format the external disk. If you right click on the disk and select 'Format' it only gives you an NTFS option. If you open a command prompt window and try a 'FORMAT M: /FS:FAT32' it verifies all 38154Mb then says that it is too big for FAT32. Which is to be expected since WIndows 2000 and XP arbitraily imposed a disk size limit of 32 GB for an FAT32 volume.
I do not tink I have the option of formating from an XP boot disk as I only have a manufacturer's 'Recovery' CD which I am reluctant to boot from. Anyway, why should it be any different in terms of disk size limit.
Let me restate the problem
-Windows sees the disk as empty apart for the usual system files and is a perfectly normal well functioning external disk
-the display panel on the JOBO GIGAOne says there is only 1GB free
So surely this is a problem with the JOBO hardware/firmware/software, it is not a Windows problem.
Thanks Pincer
- I did a chkdsk /f and it converted three lost clusters to files which I then deleted. I then powered off/on the JOBO device and it came up showing 38GB of free space.
