Restore an image to ssd drive

Thread needs solution

Is it safe to restore an image of my C drive to an existing ssd drive that contains a corrupted Win 7. I heard that it is bad to format an SSD drive. Does Acronis format the drive before installing the image

Thankyou

Yes it is safe. Many users are paranoid about writing large amount of data to SSDs (performance degradation and wear), and many of these concerns are unwarranted on modern systems and recent OSs.

Some practitioners recommend to do an ATA secure erase (a specific ATA operation, please do not use any secure wiping software) to reset the SSD to manufacturing performance every now and then (every 6 months for high intensity SSD usage).

I am also having the same doubts. Pat L hasn't fully answered the question in my opinion.. My niggle is that we are told that SSDs work completely to a Hard Disk, ie: to delete is not to delete, a specific command has to be issued (which escapes me, but fills the disk with zeros) or even a quick format. kuppatea asked the question, Does Acronis format the drive before installing the image? If nothing is done, then surely the SSD is going to have the corrupt system still in situ as well as the restored image .. Please tell me I am wrong . I have Acronis 2014

The hard drive isn't formatted in the case of a restore, however the MBR and boot sector contents are cleared before a restore continues.

Thanks Colin. But what happens to the rest of the leftover garbage? Can this be over written like a conventional HD? Its been said time and time again that SSDs will just continue building junk (unless a TRIM command is issued) up to the point where it is so chocca block that it will slow down to a crawl

I don't know the answer Brian, except that overwriting sectors works the same way basically as Trim does for SSD drives. I suspect (but am not sure) that when an image is recovered, the SSD is instructed to write 0xFF to a 4kB page, then a page of data is written to the drive and so on until the complete image is restored, this is how overwriting is performed with SSDs. Essentially this is an extreme 'Trim' function. Any pages that are not overwritten but subsequently not used are then recognised by Windows (W7 and later) and a trim command is issued on those pages, laternatively if the drive has it's own internal trim function it might do this off it's own back.
