FAT32 partition -- harddisk seems too small
Posted: 21 May 2020, 19:17
Hi,
I have a 4 GB disk with a single FAT32 partition (trying to recover). The drive was never bootable as far as I remember; it was always external USB. I get "harddisk seems too small". I don't have a 26 TB drive
Screenshot
When I try to manually create the partition, TestDisk CHS limits prevent me from entering the CHS provided by TestDisk quick search - the ending cylinder value (396645) is too high for TestDisk and it wants to start at cylinder 0.
