External USB need Repair on every cable insert An external USB storage is used. It is a 2.5 inch SATA hdd along with SATA-USB 3.0 adapter. GPT with two data partitions, one in FAT, another in Mac OS file system. That one in Mac OS file system is used as second/alternate target for Time Machine Backups. Before the TM backup process is started the Verify is made for HDD and the Mac OS file system partition - manual start. The made observations are that after every usb cable pull and plug-in the Verify does not succeed and completes with recommendation to make Repair. In the fact it is sufficient after successful usage (here the TM backup) to pull the usb cable and after few seconds to plug in it back in order to run onto effect as described above. Is this a sign of abnormal behavior? Something to be trouble-shoted?
