Legend Posted October 28, 2009 Share Posted October 28, 2009 We conduct numerous tests at Apple Labs@Infinite Loop. Currently we have found issues ONLY IF you are using the Disk Utility>Restore to clone a previous image of your old drive. The Restore feature seems to be corrupting the GUID Partition Table. We currently recommend for Mac users to do a fresh install. If you need to migrate the old data from your previous HDD, either manually transfer the data or use the Migration Assistant. For further support, please list the following information: 1. SSD Model 2. MacBook/Pro model number 3. OSX version 4. Install method: Fresh Install, Clone Software or OSX>Disk Utility>Restore 5.

jzsimon Posted October 28, 2009 Share Posted October 28, 2009 Legend, Does that mean if we restore a Time Machine backup, instead of restoring a clone via Disk Utility, that everything should be fine (as far as you know)? Link to comment Share on other sites More sharing options...
Legend Posted October 28, 2009 Author Share Posted October 28, 2009 Time machine is not doing a block to block copy like Disk Utility>Restore and should be similar to Migration Assistant in regards to file to file copy. Thus it should be okay but I have not tested it ATM. Link to comment Share on other sites More sharing options...
critical_limit Posted October 30, 2009 Share Posted October 30, 2009 @ Legend: I´ve configured a Macbook Pro 13" (Mid 2009) with two X128 in Raid0.

Here are some facts: Installation of Snow Leopard using a 8GB USB Stick: 12:48 mins from start to reboot Systemstart from Power-on to ready-to-use: 19 seconds xBench (compared to Seagate Momentus 500GB 7200rpm): Results 49.00 with Seagate Momentus 500GB/7200 System Info Xbench Version 1.3 System Version 10.6.1 (10B504) Physical RAM 4096 MB Model MacBookPro5,5 Drive Type ST9500420AS Disk Test 49.00 Sequential 98.92 Uncached Write 144.12 88.49 MB/sec [4K blocks] Uncached Write 154.00 87.14 MB/sec [256K blocks] Uncached Read 46.45 13.60 MB/sec [4K blocks] Uncached Read 182.47 91.71 MB/sec [256K blocks] Random 32.57 Uncached Write 10.23 1.08 MB/sec [4K blocks] Uncached Write 165.19 52.88 MB/sec [256K blocks] Uncached Read 83.59 0.59 MB/sec [4K blocks] Uncached Read 140.87 26.14 MB/sec [256K blocks] Results 273.27 with 2 Corsair X128 in Raid0 System Info Xbench Version 1.3 System Version 10.6.1 (10B504) Physical RAM 4096 MB Model MacBookPro5,5 Drive Type Macintosh HD Disk Test 273.27 Sequential 176.94 Uncached Write 214.35 131.61 MB/sec [4K blocks] Uncached Write 423.91 239.85 MB/sec [256K blocks] Uncached Read 71.85 21.03 MB/sec [4K blocks] Uncached Read 600.83 301.97 MB/sec [256K blocks] Random 599.86 Uncached Write 246.07 26.05 MB/sec [4K blocks] Uncached Write 773.46 247.61 MB/sec [256K blocks] Uncached Read 1890.39 13.40 MB/sec [4K blocks] Uncached Read 1278.14 237.17 MB/sec [256K blocks] Link to comment Share on other sites More sharing options...
Shimodax Posted November 2, 2009 Share Posted November 2, 2009 Btw, a very easy to use file based backup/restore programm is called SuperDuper!. I regularly use it to copy installations between drives and partitions (it makes them bootable and everything) Link to comment Share on other sites More sharing options...
Shimodax Posted November 2, 2009 Share Posted November 2, 2009 FWIW I did an installation with DiskUtils restore today, pulling partitions to the fields (not the root hard disk). The DiskUtil while copying partition to partition said "Copying files ...". I've seen "Copying blocks ..." in the past too, not sure what would cause DU to use either form.

aublumberg Posted November 2, 2009 Share Posted November 2, 2009 I had a P256 failure on my MBP and after doing a fresh Snow Leopard install did a Time Capsule restore, works fine. Link to comment Share on other sites More sharing options...
maxito Posted November 3, 2009 Share Posted November 3, 2009 Same thing but using a fresh install and Migration Assistant: seems to work fine now. Link to comment Share on other sites More sharing options...
