Hi everyone,
I searched similar topics on this forum as well as numerous other resources available throughout the web, but I still haven't managed to solve my problem.
Just today I found out that I can no longer see my external HD (Seagate FreeAgent Desktop, 500gb). The disk is approx three years old, but so far I have never had any issues with it. Important information: for the past couple of weeks, every now and then, I would receive a OS "Device Removal" message (as in: improper removal), although I wouldn't touch anything. The drive was connected via an unpowered USB hub, so one might think that the message was due to insufficient power, but this type of HD has a power brick. However, I do concur that the problem was probably caused by poor quality USB hub.
Checks I performed and facts:
- The drive doesn't appear on desktop nor in finder
- The drive doesn't appear in terminal "ls /volumes" command
- The drive does appear in Disk Utility, but it's partition is greyed out.
- The partition won't mount in Disk Utility.
- Disk Utility First Aid hasn't detected any problems with the disk or - to be more exact - it did once and fixed it. Further checks returned no errors/problems.
- No information available in "Owners Enabled" in Desktop Utility (marked: "-")
- Seagate Disk Utility won't see it neither.
- Connecting it to a different USB port and with a different USB cable doesn't help.
- Logging into the system with "root user" and trying to change the access to the drive yielded no positive results. The disk doesn't appear in finder, and although it does appear in Disk Utility there is no option to change access.
I am now downloading Disk Warrior as I have read elsewhere that it might help. Will update on any results or lack thereof.
In the meantime - does anyone have any idea what to do?
Cheers,
marcinito
