I'd have my backup to fall back on but let's go with no backups.
1. STOP USING THAT HDD!
2. Remove it so we can work it later and install then setup your new HDD.
3. All working? Time to add the old HDD so we can run RECUVA on it (what is Recuva and tutorials are on the web) so we can pull what Recuva finds onto that new drive.
HDD not migrated, no access to stored Data, Lost drive access, defect SATA
My system runs on an SSD[e:] and my programs on an HDD[e:] (Barracuda 2TB).
I have an additional internal 2TB HDD for games (Hitachi)
Today I installed an additional 2TB HDD for media (Barracuda) [m:]
In that process I switched up my SATA configuration on the mainboard (GA-Z97-D3H S1150)
After setting up the new drive I noticed that was missing.
After some testing I found out that the (till then unused) SATA port that I connect to was not working.
I plugged back into the old (working) port and on starting windows took a long time checking and repairing (canceled it first but as the drive was not visible I restarted and let it check).
Now: is visible as drive with only 465GB of space (which was the free space left) the folder is empty, and I am unable to see and access my data.
Checking with HDDtune the drive is healthy and undamaged.
CHKDSK is not working on it.
Same problem on different pc (adapter).
Disk management shows me the 2TB on the bottom as completely assigned but just the 465GB as partition size.
Last events report that the device has not been migrated, don’t know if that might help, all other devices are.
Does someone know what might be going on or a way to access the 1,5TB data, that seem to be still on the drive?
I guess that formatting is my last option, but the data loss would be a painful.
I am thankful for any help or direction to search.
My system is in German but if you need screenshots let me know.
