I would upgrade OS X to 10.6.8 (besides being supported from Apple still with security and other updates, likely better support for SSD as it was only 2011 that we saw more Macs ship with Macs and spent half the year or more ironing out SATA3 + SSD issues.
- I have seen a couple others with problems with the m4 mentioned here in the last two weeks and with cloning
* Crucial m4 - there is a firmware update, which was a separate issue
* 2008s seem to have problems like this
* Does Vista show TRIM enabled?
* 512GB is for most users overkill for a boot drive.
* A small 128GB is enough or even 240GB and be able to afford a 2TB enterprise drive for data
*. You get great IOPS but hampered - not that a boot drive needs 450MB/sec but SATA2 and 275MB/sec
* OS X does not support TRIM but then the m4 does an excellent job on its own.
* SATA ports do not operate in AHCI mode for Windows, necessary for OS level TRIM
You have something very likely in your system - symantec, kaspersky, but something - try make a backup image (you need one anyway going forward) and do a clean install to the SSD.
That is what some people did anyway - goes fast - then use Setup Assistant, but only after testing etc
- just some off the top random thoughts....

I do have the time to do a fresh install. If necessary, I can use the cold start. I also do not wish to upgrade from OS 10.5.8 because my backup device is connected via a SATA card that (according to past reports) had difficulty with OS beyond 10.5.8.
Perhaps the question is: What is different between a cold boot and a restart that could result in the former succeeding and the latter failing routinely?
Would it be of any use again to disconnect all cables and the power cord and then reconnect? I did so earlier todat when I installed the SSD.
Thank you in advance for your help,

Please forgive my typo in the previous reply: I do not have the time to do a fresh install. Apologies.

you don't have tiime to have your system drive corrupted is what you mean.
Installing the OS on an SSD is quick; but your penny and I won't waste my time either.
WE have had long threads on what and why a sytem will have issues wth sleep, cold boot, restarts, etc. They seem endemic to 2008s more than any.
