Dear WAMUG’ers, I use an external disc drive to which I get Time Machine to save its backups. I have however had troubles with different drives to mount on the desktop, and thus TM being unable to do its backups. Running Disk Utility to ‘Repair’ the disc, it reported unable to repair. I tried TechTool Pro 12 which also reported being unable to repair.
Disk Utility did show the external drive, but due to the fsck–hfs process running in the background, I suspect trying to repair the Backup drive used by TM, the drive was ‘greyed -out’ and I could not eject the drive. This is now the 4th Western Digital Drive which encountered this problem on 2 different iMacs, used exclusively by Time Machine. Every time I tried to reformat the drives concerned, whenever DiskUtil could do it, but the problem of not mounting up occurred again. I cannot believe that WD drives could be so unreliable as to fail in sometimes less that 7 or 8 months! The last one to ‘die’ is a 6TB My Book purchased about 8 or 9 months ago. I am now wondering whether TM is the culprit? To note that I have 2 other external HD connected to my iMac used to save some of my heavy files - mostly photos and books, and they have not shown any sign of corruption or of failing (as yet!) and have been in use for a few years now. By the way, all the external drives are connected via USB. I would appreciate any views on this matter. Do I have to purchase another 6TB drive, and if so what are the reliable brands out there? Many thanks. Keep safe and have a great night. Philippe C. Philippe dit la Grenouille ...🐸 iMac mid 2010 20GB RAM High Sierra v. 10.13.6
