![]() Once i managed to reduce the volume size and it worked stable i kind of let go of that idea. At one point i suspected some malware on the USB Flash drive, maybe even in the firmware. Summary: Now i felt like i eventually had a success but not a solid approach. Mutiple tests later, still stable at +40GB out of 64GB. Next i decided to use gdisk to create the partition from 0%-70% and found it worked. Somehow, now it stopped at 75% and testdisk was unresponsive. More attempts, rebooting etc to no avail.Įither way, eventually, i ran analyse again. Now using testdisk to create a partition was considered, which again worked, then failed. Bizarre to find after reboot it showed a GPT table as was attempted before. Partitions could also "loose" information after a reboot.Įventually, after many partitioning attempts on a Linux system (gdis, cfdisk, parted, testdisk) I decided the have testdisk wipe and create an MBR. This could be one tool finding ntfs, another ext4, another hpfs. Somehow showing historical attempts for different filesystems present depending on what tool was used. Multiple repartitioning attempts on both OSX and Linux failed. Initally on OSX (High Sierra) later on Linux. Initial actions performed were repartitioning, on each occassion this resulted in a success-fail condition with recurring i/o error notification. I tihnk to have seen this once before where an Apple screws up the filesystem since to OSX FAT32 cannot hold such a large size volume (64GB) I assume there is where things went wrong. Every app i tried said the stick was a 64GB FAT32 filesystem. Both on an Apple OSX machine and a MS Windows machine it was found the stick would not accept the pictures as before. Eventually resorting to testdisk and running Analyse my suspicion was confirmed this stick was somehow damaged.īefore: The original pictures are on a portable usb hdd drive attached to a mac, the usb stick is as purchased. When asked to look into why an USB stick could not be used anymore i ran into a number of bizarre events. As such i felt it was worth the effort and an interesting experience. Background: the usb stick had been 'painted' with many layers of nail polish by an artist who wanted to make it into a present. This post more to document and discuss, learn than anything else.
