First thing, stop using the phone. Every new photo or app install lowers your chances. Were the photos on internal storage or SD card?
So I messed up. Deleted some old photos from my Android phone, then later cleared Trash thinking I was freeing space. These were family pics, not backed up (yeah I know…). Tried a couple Play Store apps but they just show current files. Am I totally screwed or is there legit way to get them back?
Also stop opening them repeatedly in Photos app. Windows Photos sometimes worsens corruption by rewriting metadata.
Then those aren’t totally dead. Standard recovery tools won’t fix broken image structure though. You’d need proper photo repair software that rebuilds headers using reference images.
Checked a few. Some are zeroes, but others have readable headers and random data after that.
Quick check: open one of the bad images in a hex editor. If it’s mostly zeroes, nothing can fix that. If there’s structured data, repair might still work.
That flickering between fine and corrupted usually means partial data is there. Viewer reads cached preview, then hits bad blocks when decoding full image.
Yeah it’s an SSD actually. That’s what worries me. But some files do open sometimes, which is confusing.
If it’s an SSD or newer drive, there’s a good chance TRIM already wiped parts of the data. Recovery tools can rebuild filenames but not missing content.
So I recovered a bunch of old photos from my external drive after accidentally deleting them. Recovery finished fine, file sizes look normal, but now a lot of images won’t open or show weird blocks. Some open once, then break again. Did I screw something up during recovery or are these files just gone?
For the same storage capacity, given that a RAID 10 consists of two RAID 1 arrays, is RAID 10 at least twice as likely to fail?
However, as the four drives in the RAID 10 will be half the capacity of the two drives in the RAID 1, will this also half the chance of a drive failure during rebuild? If so, there is comparable risk of failure between RAID 10 and RAID 1.
However, a RAID 10 will produce more heat and vibration than RAID 1 and draw more power. This will increase the failure rate of RAID 10.
Discuss.

Internal storage sadly. Phone is still working fine though. Haven’t used it much since.
