Hi guys, Recently my Windows 7 OS wasn't booting in and I gave it for service . They came back saying that my Laptop had a faulty HDD. As per their recommendation i got a new HDD and they said they were not able to backup data as the drive changed to "dynamic" and to take it to data recovery experts for safe recovery. I eventually did that part myself using opensource tools (testdrive) and converted the old harddisk to an external USB hdd. Primarily it is not showing an error. But on SMART test (using HDD Scan) it shows fault with these two parameteres a) Reallocation Sector Count and b) UltraDMA CRC Errors How bad are these?? Full Scan report is as shown in attachment. Would like to know whether this HDD can be used for storage? Was it right from the service guy's part to say that it is faulty ( he said it got major errors as per his diagnosis). Or was I fooled to buy a new one?
