Hi,
I upgraded my laptop with a 512 GB Crucial MX100 SSD. The first SSD starting pausing for a minute or so every so often, then longer and longer. Finally after a couple of days, the data partitions disappeared and were coded as RAW.
I replaced the SSD with the same model and restored the partitions leaving 100GB free space after the C Drive and left the last partition un-encrypted.
Today, the three bitlocker'd partitions are wiped again. Instead of saying RAW, they say nothing, just 0 for used and free space with File System blank, but that might change if I reboot.
I left 100 GB unused for garbage collection (20%) and future emergency space, and other than doing "quick" formats, then bitlockering, then loading data, there has not been much disk activity.
Partition | Drive | Space | Bitlocker |
Primary | SR | 350 MB | No |
Primary | C: Unallocated | 220 GB 100 GB | P |
Primary | T: | 28 GB | P |
Logical | H: | 32 GB | P |
Logical | M: | 24 GB | P |
Logical | U: | 73 GB | No |
The wiped drives were bitlockered, but C: didn't get wiped. T: and M: unlock automatically during the boot and H: unlocks manually.
There is no TPM in this machine so encryption is done at the OS level.
As far as I know, there hasn't been any power fail as the machine was left on last night and came out of hibernation OK this morning. I do not know when the drives messed up this time but they were OK yesterday. Windows Defender says it is up to date.
Any suggestions as to which of Bitlocker, Win 8.1, the laptop (Aspire 3830TG-6415), or the SSD could be wiping the partitions?
I was wondering if it could be some mess up with TRIM between Windows 8.1 Disk Formatting, Bitlocker, and the SSD's automatic garbage collection?
Thanks, Bob.
