Other Help Topics :: large fat32 drive size error



a little while ago I bought an external usb seagate 750g drive.  its great for all my movies and music. df -h shows 110gb though i hadn't noticed it for a little while till i configured saw torsmo to show it.
Now i have found that it doesn't even show most of the files on the drive and sometimes any files i add can corrupt.

I have just upgraded/reinstalled to 4.4.3 for my "http/smb/dhcp/ssh/vnc/no-ip/dyndns/ftp/partimage wireless/eth routing itx server" and it still does the same thing.  so i had to do a poor and unsafe workaround, mounting the 750gb on an old win2k laptop, and sharing it so dsl can see it and re-share it, now showing the full 750gb next to a 160gb hda2.

anyone got any ideas?  i dont want to attempt a format to ext2/3 and all the win defrag and error checking shows me the drive is fine.
I don't know if it is the same issue, but I have a maxtor MSS+ 500GB external hd. Even though the hd runs linux internally, it is configured such that only windows can set it up as a share and I can only access the drive via samba.
stunix: Try gparted to test the drive.

(And Juanito, your's is a network drive, right? Wouldn't be the same thing)
Kernel messages from plugging it in?
sorry for the delay but i didnt want to fiddle till id finished reimaging 10 new machines for work.
here is dmesg showing log of usb drive

it can now see 700gb but only 11g of data on it.

when mounted on M$ and remounted df and torsmo shows 510g on it.

currently all eggs are in this basket till i save to get a second one so im a little reluctant to do an fsck incase it decides to clean up everything outside the 11gb it sees.
