Earlier in the week fdisk was reporting 48MB for the disk size. I tried gparted + gpart on it yesterday just before sending my email (the repair partition option in gparted) and that didn't seem to make any difference, gparted still showed 48MB. Attempted to create a partition too (48MB in size) which didn't seem to do anything. However plugging it in again, fdisk is now showing this: Disk /dev/sdb: 1000.2 GB, 1000204886016 bytes 16 heads, 63 sectors/track, 1938021 cylinders, total 1953525168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x5476743a Device Boot Start End Blocks Id System /dev/sdb1 63 1953522143 976761040+ 7 HPFS/NTFS/exFAT Which is not the 2GB it used to be (and I'm pretty sure I used it to capacity in the past). Going to try formatting through Windows to see if that makes any difference, though I did try the Windows disk management earlier in the week too, can't remember what it showed, think it was 0 space on the device, but it might have been the 48MB. -- imalone -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
